US Solar Duties Target Asian Cell Imports as Washington Defends Domestic Manufacturing

US solar

US solar duties on cells and modules from India, Indonesia and Laos will raise the cost of imported photovoltaic products after the Commerce Department issued preliminary antidumping findings. The decision allows customs authorities to begin collecting cash deposits from importers.

US solar duties are part of a broader trade case brought by domestic manufacturers that accuse foreign producers of selling solar products at unfairly low prices. The case covers crystalline silicon photovoltaic cells and modules imported into the US market.

US solar duties now combine antidumping margins with earlier countervailing duties. General preliminary duty rates stand at roughly 234% for India, 140% for Indonesia and 103% for Laos.

The decision comes at a critical point for the US solar supply chain. Washington is trying to expand domestic clean energy manufacturing while reducing dependence on lower-cost Asian imports.

Duties Raise Costs for India, Indonesia and Laos Solar Supply

The preliminary antidumping margins differ by country and company. Indian producers face the steepest margin, at about 123%.

Companies in Indonesia face a lower dumping margin of about 35%, while firms in Laos face around 22%. These rates come on top of countervailing duties announced earlier this year.

The combined duty levels could significantly affect solar module sourcing decisions. Importers may need to reassess contracts, landed costs and supply availability if final rates remain high.

The investigation was triggered by a petition from the Alliance for American Solar Manufacturing and Trade. The group includes US manufacturers such as First Solar and Mission Solar Energy, along with Qcells, a subsidiary of South Korea’s Hanwha.

The coalition argued that companies in the three countries benefited from subsidies and sold solar products into the US at unfairly low prices. It also alleged that Chinese-linked manufacturers operating in Southeast Asia were undercutting American-made products.
The decision strengthens the trade protection around US solar manufacturing. But it may also raise near-term procurement costs for developers that depend on imported cells and modules.

Domestic Manufacturing Push Collides With Deployment Costs

The case highlights the tension inside US clean energy policy. The government wants more domestic solar manufacturing, but the solar deployment market still relies heavily on imported equipment.

Antidumping tariffs are intended to counter imports sold below normal value. Countervailing duties target products that benefit from government subsidies.
Together, these duties can protect domestic producers from price competition that regulators view as unfair. They can also reshape trade flows by pushing buyers toward alternative origins or US-made products.

For manufacturers, the ruling supports investment in domestic capacity. Higher duties can improve the competitiveness of US-made solar products and encourage new factory spending.

For project developers, the impact is more complicated. Higher module costs can pressure project economics, especially where power purchase agreements, tax credits and construction budgets were based on cheaper imported supply.

Commerce is expected to issue final antidumping determinations in early September. Until then, the market will face uncertainty around final rates, supplier exposure and contract pricing.

The broader industrial message is clear. Solar policy is no longer only about renewable energy deployment. It is also about manufacturing location, trade enforcement and supply-chain control.

The Metalnomist Commentary

The new US solar duties show that clean energy deployment and industrial protection are increasingly inseparable. The key question is whether Washington can build domestic solar capacity fast enough to offset higher import costs without slowing project growth.

T1 Energy Plans 5GW Solar Cell Plant in Texas to Strengthen US Supply Chain

T1 Energy

Texas Facility Marks New Phase for US Solar Manufacturing

T1 Energy announced plans to build a 5GW solar cell facility in Texas, aiming to address critical gaps in the US solar supply chain. The $850mn G2_Austin plant is scheduled to start production by late 2026. This project follows T1 Energy’s acquisition of Trina Solar’s US assets in 2024 and a rebranding from Freyr Battery, which abandoned its $2.6bn battery storage project in Georgia.

The new facility will supply cells to the 5GW G1_Dallas module plant, reducing reliance on imports from Asia. Current US solar cell capacity remains just 2GW, compared to 56GW of module production. This imbalance highlights the urgency of building more domestic cell production.

US Tariffs and Technology Drive Expansion

T1 Energy’s Texas project benefits from US tariffs and tax incentives, which encourage domestic solar manufacturing. The US Commerce Department has imposed anti-dumping duties on PV cells from Southeast Asia to counter circumvention of Chinese tariffs. Meanwhile, T1 Energy will adopt high-efficiency TOPCon technology, which uses n-type polysilicon. This move reflects the global shift from older Perc technology toward higher-performing solar cells.

However, tariff uncertainty has caused the company to lower its module production forecast for 2025 to 2.6–3GW, down from 3.4GW. T1 Energy is also holding off on long-term power purchase agreements until cost visibility improves. Despite these challenges, the Austin facility represents a major step toward reshoring solar cell production and securing domestic supply chains.

The Metalnomist Commentary

T1 Energy’s 5GW solar cell project signals a turning point for US clean energy policy, linking tariffs, incentives, and new technology adoption. If executed successfully, this facility could strengthen US energy independence while setting a precedent for integrated solar manufacturing in North America. However, cost pressures and tariff volatility remain significant risks for long-term stability.

Solarcycle Georgia Recycling Plant Strengthens the US Solar Materials Loop

Solarcycle

The Solarcycle Georgia recycling plant marks an important step in building a domestic solar materials loop. Solarcycle has started operations at its new facility in Cedartown, Georgia. The site uses upgraded technology that more than doubles throughput versus earlier systems. As a result, the Solarcycle Georgia recycling plant could become a meaningful part of the US clean energy supply chain.

This project matters because solar waste is becoming a larger industrial issue. More end-of-life panels now need recovery rather than disposal. Solarcycle said the process diverts all material from landfill and recovers about 96pc of panel value. Therefore, the Solarcycle Georgia recycling plant is not just a waste solution. It is also a materials recovery platform.

The recovered materials also carry real industrial value. Silver, copper, aluminum, and glass are all embedded in used solar panels. These inputs matter for manufacturing economics and supply resilience. Consequently, solar panel recycling is becoming more relevant to both sustainability and domestic sourcing.

Solar Panel Recycling Is Moving Toward Industrial Scale

Solar panel recycling is shifting from niche activity toward industrial infrastructure. The Cedartown facility is already processing thousands of panels each week. Solarcycle expects that figure to rise to 1mn panels annually by the end of 2026. As a result, the company is building capacity for scale rather than demonstration.

Full capacity makes the project even more significant. The plant can process up to 5 GW per year of solar panels. That level of throughput places the facility among the more serious recycling assets in the US solar chain. Therefore, the Solarcycle Georgia recycling plant could influence how the market thinks about end-of-life solar economics.

The technology angle also matters. Higher throughput and full landfill diversion improve the commercial case for recycling. Better material recovery can support stronger margins and more stable downstream reuse. Meanwhile, it gives developers and manufacturers a clearer pathway for circularity.

Recycled Solar Glass Could Deepen US Solar Materials Capacity

Recycled solar glass is the next major part of Solarcycle’s strategy. The recycling facility sits next to the company’s planned solar glass manufacturing plant. That plant is expected to break ground in mid-2026 and begin producing glass in 2028. Consequently, Solarcycle is linking recycling directly to new manufacturing capacity.

This integrated model matters for the broader US solar sector. Domestic manufacturing has become more important as buyers seek local supply and policy support favors US production. Solarcycle said it has already secured customer commitments for more than 80pc of the future glass plant’s planned 5 GW capacity. Therefore, demand for recycled and US-made solar materials appears to be strengthening.

The business model also shows a wider industrial trend. Recycling is no longer just about compliance or waste reduction. It is becoming a feedstock strategy for new manufacturing. As a result, the Solarcycle Georgia recycling plant may prove more important as the front end of a circular materials chain than as a stand-alone recycling site.

The Metalnomist Commentary

This project stands out because it connects recycling scale with future manufacturing capacity. Solarcycle is not simply collecting old panels. It is building a domestic solar materials loop that could matter more as US clean energy deployment accelerates.

Azur Space Solar Cell Expansion Signals Stronger Demand From the Satellite Market

Azur Space

Azur Space solar cell expansion is set to continue in 2026 as the company targets another major capacity increase. Germany-based Azur Space plans to lift production by 25pc this year. Its parent company, 5N Plus, expects capacity to rise steadily through the second half as investment supports process optimization and automation. As a result, Azur Space solar cell expansion is becoming a clear signal of stronger demand in the satellite supply chain.

This development matters because Azur is already coming off two years of strong growth. The company previously increased capacity by 35pc in 2024 and 30pc in 2025. Another 25pc increase would extend that momentum into a third consecutive year. Therefore, Azur Space solar cell expansion reflects sustained confidence rather than a one-off adjustment.

The timing also fits a broader technology trend. 5N Plus said faster adoption of artificial intelligence is boosting demand from the satellite sector. That suggests the expansion is tied not only to traditional aerospace demand, but also to digital infrastructure growth. Consequently, satellite solar cell demand is gaining support from a wider set of end markets.

Satellite Solar Cell Demand Is Moving Into a New Growth Phase

Satellite solar cell demand is becoming more structurally important as space-based infrastructure expands. More satellites require reliable power systems, and high-performance solar cells remain a core part of that requirement. This makes production scale more valuable for suppliers serving advanced aerospace applications. As a result, Azur Space solar cell expansion could strengthen its position in a market that is becoming more strategic.

Artificial intelligence is adding another layer to that demand story. Growth in AI applications is increasing pressure on data networks, communications systems, and related space assets. That can support more satellite launches and a larger installed base in orbit. Therefore, satellite solar cell demand is now being influenced by digital technology trends as much as by aerospace cycles.

This is important for the wider semiconductor and specialty materials chain. Space-grade solar cells are not bulk commodity products. They require higher performance, tighter manufacturing control, and strong quality consistency. Meanwhile, added automation can help producers scale without compromising technical standards.

5N Plus Semiconductor Strategy Gains More Industrial Depth

5N Plus semiconductor strategy appears to be moving deeper into high-value aerospace markets. The company did not disclose the financial size of the new investment, but it said the plan includes process optimization and additional automation. That suggests management is focusing on efficiency as well as higher output. Consequently, Azur Space solar cell expansion looks like a capacity and productivity story at the same time.

This approach matters because repeated annual expansions can create cumulative competitive advantage. Three years of sustained capacity growth can improve customer confidence, strengthen delivery capability, and widen market share opportunities. Therefore, 5N Plus semiconductor strategy may be shifting from niche participation toward stronger industrial scale.

The broader implication is clear. Space-related demand is no longer isolated from the rest of the technology economy. It is becoming more closely linked to AI, communications, and advanced electronics. As a result, Azur Space solar cell expansion could become one of the more interesting signals of how specialty semiconductor demand is evolving.

The Metalnomist Commentary

This expansion is important because it connects satellite demand with the wider AI infrastructure story. Azur is not only adding output. It is strengthening its role in a part of the supply chain where performance and reliability matter more than simple volume.

First Solar Module Sales Hit Record as US Manufacturing Capacity Expands

First Solar

First Solar module sales reached a record high in 2025 as the US thin-film solar manufacturer benefited from strong domestic demand and a changing tariff environment. The company shipped 17.5GW of modules, up 24pc from its previous record of 14.1GW in 2024, and slightly above its revised annual guidance.

First Solar module sales also translated into stronger revenue. Net sales rose by $1.01bn from 2024 to reach $5.2bn in 2025. Fourth-quarter sales increased to $1.7bn, reflecting continued momentum in utility-scale solar demand and the company’s strong position in the US market.

The outlook for First Solar module sales remains solid in 2026. The company expects to sell 17-18.2GW of modules this year, including 12.6-13.1GW in the US alone. However, its contracted backlog fell to 50.1GW from 68.5GW a year earlier, showing that growth remains exposed to project timing, policy uncertainty, and customer procurement decisions.

US Solar Manufacturing Becomes the Core Growth Engine

First Solar is shifting more production toward the United States as domestic manufacturing becomes a strategic advantage. The company produced 16.1GW of modules in 2025, including 10GW from US facilities, 2.8GW from India, and 3.3GW from other regions outside the US and India.

For 2026, First Solar expects total production of 16.5-17.5GW. US production is forecast to rise sharply to 13-13.3GW, while Indian output is expected at 2.6-2.8GW. Production from other regions is expected to fall to 0.9-1.4GW, showing a clear rebalancing of the company’s manufacturing footprint.

The company is also expanding its domestic capacity base. First Solar began commercial production at a new Louisiana facility this year, its fifth manufacturing site in the US. A 3.7GW plant in South Carolina is expected to begin production from the fourth quarter, further strengthening the company’s US solar supply chain position.

Tariff Uncertainty Reshapes Global Solar Production

Tariff uncertainty is becoming a major factor in solar manufacturing strategy. First Solar expects significant underutilisation at its plants in Vietnam and Malaysia because demand for output from those facilities has been constrained by trade policy uncertainty.

This shift highlights how solar supply chains are being reorganised around policy risk as much as cost. Buyers increasingly want modules that can avoid tariff exposure, qualify for domestic incentives, and support long-term project certainty. That gives First Solar an advantage because its US manufacturing base aligns with domestic energy security and industrial policy goals.

Still, the company’s 2026 sales target of $4.9bn-5.2bn suggests revenue may not grow sharply despite higher expected module volumes. This reflects the complex balance between pricing, product mix, policy incentives, and manufacturing utilisation across different regions.

The Metalnomist Commentary

First Solar’s 2025 record shows that solar manufacturing is becoming a policy-driven industrial sector, not only a renewable energy market. The company’s US capacity expansion gives it a strong position, but tariff uncertainty will continue to reshape where modules are made and sold.

5N Plus Supply Security Becomes Top Priority as Semiconductor Materials Demand Rises

5N Plus

5N Plus supply security has become the company’s top priority as geopolitical volatility, trade uncertainty and rising customer demand reshape the semiconductor materials market. The Canadian producer said reliable supply is now essential to avoid disruptions for customers in renewable energy, space solar power and performance materials.

5N Plus supply security is becoming more important because the company operates in sensitive material chains serving semiconductors, solar cells and advanced industrial applications. These markets require consistent quality, qualified feedstock and stable delivery.

5N Plus supply security also reflects a wider shift in critical materials procurement. Customers are no longer focused only on price. They increasingly want trusted suppliers that can manage input volatility, origin risk and operating disruptions.

The company reported first-quarter revenue of $117.9mn, up 33% from a year earlier. Profit increased by 86% to $17.8mn, supported by growth across both business segments.

Specialty Semiconductor Revenue Rises on Solar and Space Demand

Revenue from the specialty semiconductor segment rose by 37% to $86.2mn in the first quarter. Higher volumes from the terrestrial renewable energy industry drove the increase.

Demand from the space solar power sector also supported growth. This is strategically important because space-grade solar cells require high-performance semiconductor materials and strict qualification standards.

5N Plus’ Germany-based solar cell producer Azur Space is expanding capacity again. The company expects to add another 25% of capacity by the second half of this year.

That follows capacity increases of 35% in 2024 and 30% in 2025. The expansion shows that demand for advanced solar cell technology remains strong across terrestrial and space applications.

The growth also highlights the strategic role of specialty materials in energy and aerospace supply chains. Solar power, satellites and advanced electronics depend on reliable access to high-purity inputs and qualified manufacturing capacity.

Cost Volatility Tests Performance Materials Margins

5N Plus’ performance materials segment also grew in the first quarter. Revenue rose by 21% on the year to $31.7mn.

Favourable pricing conditions supported the segment, but the company expects pricing to normalise in coming quarters. That could reduce some of the revenue uplift if volumes do not offset weaker prices.

Cost volatility remains a major risk. 5N Plus expects trade uncertainty, inflationary pressure and higher input costs to continue affecting margins through the year.

This matters because semiconductor and performance materials producers must manage both upstream feedstock risk and downstream customer commitments. Any mismatch between input costs and contract pricing can pressure profitability.

The company’s results show strong demand, but also a more complex operating environment. Supply security, inventory planning, sourcing diversification and cost control will remain central to performance.

For advanced manufacturing customers, 5N Plus’ message is clear. Secure materials supply is now a competitive advantage, especially in sectors linked to semiconductors, renewable energy, aerospace and space infrastructure.

The Metalnomist Commentary

5N Plus’ results show that specialty materials companies are becoming supply-chain security providers, not just product suppliers. In semiconductor and space solar markets, reliability, qualification and sourcing resilience may matter as much as capacity expansion.

Chinese PV Industry Faces Overcapacity and Profit Losses: IEA Reports

Iea(The International Energy Agency)

The International Energy Agency (IEA) has issued a concerning report highlighting the overcapacity and declining profitability in China’s photovoltaic (PV) industry, which is the dominant force in the global solar energy supply chain. The report, presented during a webinar this Thursday, sheds light on the financial struggles faced by major Chinese manufacturers such as JA Solar Technology and LONGi Green Energy Technology, which have reported significant losses in their recent financial statements.

According to Izumi Kaizuka, an analyst at the IEA, the mood at the 17th SNEC PV conference in Shanghai this June was grim. Kaizuka quoted the founder of GCL Group, a major PV manufacturer, who expressed concern that the Chinese PV industry is "entering an ice age" due to a severe imbalance in supply and demand. The report also highlighted the bankruptcy of Zhejiang Akcome, one of China’s leading PV manufacturers, earlier this year, with the IEA predicting more closures in the near future.

China's Dominance in Global PV Production

Despite the struggles at home, China continues to dominate the global PV industry. In 2023, China accounted for more than half of the 456GW of global solar power capacity added, and nine of the top 10 PV suppliers in the first half of 2024 were Chinese-owned. The country has increased its production share across all segments of the PV supply chain, including polysilicon, crystalline silicon wafers, solar cells, and PV modules, with its share reaching 92%, 98%, 92%, and 85%, respectively, in 2023.

The rapid expansion of China’s PV capacity is evident, with the country increasing its own year-on-year solar additions by 123% from 2022 to 2023, followed by Italy (113%) and Germany (109%). However, the global demand for PV capacity is pushing countries like the EU and the US to expand their own solar production capabilities, with the EU installing over 56GW in 2023 alone.

The EU's Push for Solar Manufacturing

In response to its growing reliance on Chinese imports, the European Union (EU) has set ambitious targets to scale up domestic production of PV panels. Under the Net-Zero Industry Act, the EU aims to produce at least 40% of its annual needs for strategic net-zero technologies—including solar panels—by 2030. With current production at under 5GW annually, the EU is planning to ramp up its manufacturing capacity to 30GW per year by 2030 in order to meet its renewable energy goals.

As the global PV market faces challenges like overcapacity and supply-demand imbalances, the role of China in driving production and the EU’s efforts to boost its domestic capabilities will shape the future of the solar industry.

5N Plus Poised for Increased Tellurium Orders from First Solar Amid China Export Controls

5N Plus

US Solar Panel Giant May Boost Spot Demand as 5N Plus Expands Non-Chinese Supply and Space Solar Capacity

5N Plus Expects Surge in Tellurium Spot Sales from First Solar

Canadian semiconductor materials producer 5N Plus anticipates additional spot tellurium orders from US-based solar panel leader First Solar, as the latter moves to diversify its supply chain away from China. The shift comes after Beijing imposed new export controls on tellurium, following similar restrictions on gallium and germanium.

First Solar uses cadmium telluride (CdTe) in its thin-film solar panels and partners with 5N Plus to refine tellurium by-product sourced from Rio Tinto’s Kennecott mine in Utah. 5N Plus already has a minimum-volume supply agreement, which was increased by 50% for the next two years, effectively tripling the contract volume compared to 2022.

According to CEO Gervais Jacques, First Solar is “most likely to request more than the minimum,” signaling robust demand as the U.S. seeks to reduce reliance on Chinese critical minerals.

5N Plus Expands Non-Chinese Supply Chains and Space Solar Production

While First Solar evaluates potential disruptions from China’s export policy, 5N Plus has strengthened sourcing of key materials. It procures germanium from Europe and Canada, while maintaining a stable bismuth supply outside of China. These measures are part of a broader strategy to insulate the company from geopolitical supply risks.

Additionally, 5N Plus is scaling up its space solar division, which manufactures advanced germanium substrates used in high-efficiency satellite applications. These substrates are layered with materials such as AlInGaP, AlGaAs, and InGaAs. The company expects this business to grow by 30% in 2024, with capacity expansions ongoing through Q4.

Bismuth Chemicals to See Steady Demand from Health Sector

Beyond semiconductors, 5N Plus projects continued bismuth demand growth driven by pharmaceutical and healthcare markets, in line with global GDP trends. The company’s Lübeck, Germany facility is positioned to support this growth, supplying high-purity bismuth chemicals used in medical applications.

India Critical Minerals Supply Chain Faces Funding Gap Despite Policy Push

Indonesia nickel mining

India critical minerals supply chain ambitions face a major financing test as the country tries to reduce dependence on imported lithium, cobalt, nickel and rare earth materials. A new report from the Institute for Energy Economics and Financial Analysis warns that funding gaps, slow policy execution and raw material import dependence could delay India’s strategy.

India critical minerals supply chain development is becoming urgent because the country imports 100% of the lithium, cobalt and nickel used in clean energy manufacturing. Demand is expected to rise as India targets 30% electric vehicle penetration by 2030, along with 230GW of solar capacity and 140GW of wind capacity.

India critical minerals supply chain policy has moved quickly on paper. The government launched the National Critical Mineral Mission in January 2025 with a seven-year budget of 343bn rupees to support exploration and auctions.

However, the mission still lacks enough direct capital expenditure support for large-scale mining, refining and processing. That is the central weakness in India’s current critical minerals push.

Exploration Targets Need Processing Capital

The National Critical Mineral Mission targets 1,200 exploration projects and more than 100 critical mineral block auctions by 2030-31. This can improve domestic resource visibility, but exploration alone will not create battery, magnet or semiconductor supply chains.

Critical minerals projects require large upfront capital, long permitting timelines and technical processing capability. Mining projects can take 10-15 years to move from exploration to commercial production, creating long periods of uncertainty for investors.

India has identified major resource potential. The country reported 5.9mn t of inferred lithium resources in Jammu and Kashmir as of 2023. It also holds 13.15mn t of monazite deposits containing an estimated 7.23mn t of rare earth oxides.

The Geological Survey of India also identified 482.6mn t of rare earth ore resources through exploration projects in February. These figures suggest significant geological potential, but they do not solve the refining and separation challenge.

Rare earths are a clear example. Monazite and rare earth ore must be separated, purified, converted into metals or alloys, and qualified by downstream users before they can support magnets, defence systems, electronics or clean energy applications.

India’s midstream sector also faces pressure from Chinese overcapacity. China controls around 60-70% of global refining and processing capacity for key minerals such as lithium, nickel and cobalt, and about 90% of rare earth refining.

That dominance suppresses margins and makes new Indian refining projects harder to finance. Without price support, offtake contracts or direct capital backing, investors may hesitate to fund projects that compete against established Chinese capacity.

Import Dependence Extends Beyond Battery Metals

India’s critical minerals strategy now reaches beyond battery materials. The government classified coking coal as a critical and strategic mineral in January to reduce import dependence and support steel expansion.

This widens the funding challenge. India aims to increase crude steel production capacity to 300mn t/yr by 2030 and 500mn t/yr by 2047. Its Mission Coking Coal targets domestic output of 140mn t/yr by 2030, up from 66.49mn t/yr in fiscal 2025-26.

These goals will require long-term investment in mining, washing, transport, processing and related infrastructure. That makes critical minerals policy a broader industrial financing issue, not only an energy transition issue.

India is also seeking overseas supply partnerships. It is working with Australia, Argentina, Peru, Chile, Zimbabwe, Mozambique, Malawi and Côte d’Ivoire to secure access to critical minerals.

State-backed Khanij Bidesh India is also pursuing overseas lithium and cobalt assets. These efforts can reduce raw material risk, but they still need downstream processing and domestic industrial integration.

The global funding requirement is enormous. The International Energy Agency estimates that mining and refining will need $915bn in new investment during 2026-35 under its Announced Pledges Scenario.

For India, the strategic question is how to convert policy ambition into bankable projects. Auctions and exploration can identify resources, but refining plants, processing hubs, offtake agreements and financing tools will decide whether domestic supply chains actually emerge.

The Metalnomist Commentary

India has recognised the critical minerals problem, but recognition is not the same as industrial capacity. The next stage must focus on project finance, refining economics and guaranteed demand, or India will remain dependent on imported materials despite its resource potential.

First Solar 3.7GW South Carolina module plant lifts US solar manufacturing to 17.7GW by 2027

First Solar

The First Solar 3.7GW South Carolina module plant adds major new US capacity. First Solar will build the facility in Gaffney. The First Solar 3.7GW South Carolina module plant carries a planned $330 million investment. Therefore, it strengthens domestic solar module manufacturing.

The plant should start commercial operations in the second half of next year. The company announced the project after outlining another US plant in October. Meanwhile, developers want stable module supply and shorter delivery timelines. As a result, the First Solar 3.7GW South Carolina module plant supports supply chain resilience.

New capacity raises domestic output to 17.7GW in 2027

The new factory adds 3.7GW of annual module capacity. First Solar expects this expansion to lift domestic capacity to 17.7GW in 2027. However, ramp schedules depend on equipment delivery and workforce training. Therefore, early execution will matter.

This expansion signals continued investment in US solar manufacturing. Companies are rebuilding localized supply lines for utility-scale demand. Meanwhile, buyers increasingly prefer contracted, predictable volumes. As a result, capacity additions can improve pricing stability.

US footprint expands across multiple states

The South Carolina site will join five other US manufacturing facilities. First Solar already operates plants in Ohio, Alabama, and Louisiana. Therefore, the company widens geographic redundancy and logistics options.

More domestic module output can reduce exposure to shipping disruptions. It can also support faster project cycles for developers. Meanwhile, US-based manufacturing can simplify procurement for regulated tenders. As a result, the expansion can improve bankability for long-duration build plans.

The Metalnomist Commentary

Module capacity matters, but reliable ramp execution decides real supply. Meanwhile, US factories will compete on uptime, yields, and delivery certainty. Therefore, buyers should align contracts with commissioning milestones and proven throughput.

ReElement South African Antimony Contract Extension Strengthens Defense Supply Chain

ReElement

ReElement South African antimony contract received a significant extension as American Resources and its subsidiary ReElement Technologies expanded their existing five-year antimony agreement to ten years with an undisclosed South African mineral supplier. The ReElement South African antimony contract extension positions the US company to process 500 metric tonnes monthly of stibnite ore initially, with expected revenues of at least $29 million annually from contracted volumes, addressing critical supply chain vulnerabilities following China's antimony export restrictions.

Strategic Timing Capitalizes on Chinese Export Restrictions

ReElement South African antimony contract expansion comes at a critical juncture following China's December 2024 ban on antimony exports to the United States, alongside germanium and gallium restrictions. The partnership initially targets 1,000 metric tonnes per month of antimony-bearing ore with potential for significant volume expansion based on market demand and offtake agreements. ReElement confirmed the ore quality exceeds 50% antimony concentration, indicating high-grade material suitable for defense and commercial applications.

Meanwhile, ReElement demonstrated advanced refining capabilities achieving greater than 99.7% pure antimony(III) sulfide from antimony ore at its central Indiana facilities. The company will process stibnite ore into ultra-pure antimony(III) sulfide or antimony(III) oxide using proprietary refining technology. These compounds serve critical applications in ammunition production, missile manufacturing, flame retardants, batteries, and solar panels across defense and commercial sectors.

Market Fundamentals Support Long-Term Growth Strategy

However, the global antimony(III) oxide market provides substantial growth opportunities with 2023 valuations reaching approximately $852 million. Market analysts project compound annual growth rates of 4.9% through 2034, potentially reaching $1.43 billion total market value. Antimony trisulfide applications in military ammunition and antimony trioxide usage in flame retardants drive sustained demand across defense and commercial markets.

Therefore, the ten-year agreement with automatic renewal provisions supports long-term supply agreements while generating stable revenue streams for ReElement's operations. Initial tolling revenues from the first phase are projected to exceed $29 million annually, with substantial growth potential aligned with rising domestic demand for critical minerals. The extended contract duration delivers enhanced value for all stakeholders including commercial and defense customers requiring secure antimony supplies.

Domestic Processing Capabilities Address National Security Priorities

Furthermore, ReElement's antimony refining expansion aligns with broader US critical minerals supply chain security initiatives. The company operates as part of American Resources Corporation's integrated approach to critical mineral processing, focusing on rare earth elements, lithium, and now antimony refining capabilities. ReElement's Marion, Indiana facility provides the foundation for scaling antimony operations while evaluating additional domestic and international processing sites.

As a result, the partnership addresses urgent national security requirements for domestically produced antimony compounds essential to defense applications. Mark Jensen, CEO of American Resources and ReElement, emphasized the strategic importance: "China's recent ban on exports of antimony, germanium and gallium accelerated this opportunity, allowing us to showcase the versatility, scalability and flexibility of our technology on a global scale - filling the supply gap now present in the United States and other allied nations."

The Metalnomist Commentary

ReElement's antimony contract extension exemplifies how US critical minerals companies capitalize on Chinese export restrictions to establish alternative supply chains, particularly important given antimony's essential role in defense applications where supply security outweighs cost considerations. The partnership's focus on high-grade South African ore combined with domestic processing capabilities creates a vertically integrated approach that addresses both economic and national security objectives in the evolving critical minerals landscape.

Corning Nvidia Optical Connectivity Partnership Expands US AI Infrastructure Supply Chain

Corning

Corning Nvidia optical connectivity plans will expand US manufacturing capacity for the optical systems needed to support artificial intelligence data centres. Corning will build three new manufacturing facilities in North Carolina and Texas as it targets a tenfold increase in optical connectivity output.

Corning Nvidia optical connectivity investment also includes a more than 50% expansion in Corning’s fibre production. The move reflects rising demand for high-speed data movement across AI infrastructure, where advanced optical links are becoming as important as chips themselves.

Corning Nvidia optical connectivity partnership strengthens the domestic supply chain around Nvidia’s AI computing ecosystem. Nvidia chips require high-performance optical fibre connectivity to move data quickly and at scale across large data centre networks.

The agreement also has a strategic materials angle. The fibre-optics industry is the largest US end-user of germanium, making AI data centre buildout increasingly relevant to minor metals demand.

AI Data Centres Drive Optical Connectivity Demand

AI workloads require massive data movement between chips, servers and storage systems. As computing clusters grow, copper-based connections face performance, distance and energy-efficiency limits in some high-speed applications.

Optical connectivity helps solve that problem. It allows data to move faster and across longer distances, supporting the scale required by advanced AI data centres.

Corning’s planned facilities in North Carolina and Texas will increase domestic capacity for these optical systems. That is important because AI infrastructure is becoming a national industrial priority, not only a technology market.

For Nvidia, the partnership supports the physical network behind its chips. AI accelerators create value only when data can move efficiently through the system.

For Corning, the deal gives stronger exposure to one of the fastest-growing infrastructure markets. Optical fibre, cable assemblies and connectivity products are becoming critical components in the AI supply chain.

Germanium Demand Links AI Growth to Critical Materials

The partnership also connects AI infrastructure to germanium demand. Germanium is used in optical fibre production, making fibre expansion relevant to critical minerals and specialty materials markets.

This matters because germanium supply is already strategically sensitive. It is used in fibre optics, infrared systems, semiconductors, defence electronics and solar applications.

If AI data centre construction accelerates, optical fibre demand could strengthen further. That would increase attention on germanium availability, recycling, refining and origin security.

The transaction also includes a financial component. Nvidia has the right to purchase up to 15mn shares of Corning stock at a fixed price of $180/share, as well as a pre-funded warrant to purchase up to 3mn shares for a total price of $500mn.

That structure shows how strategic customers are moving closer to upstream and midstream suppliers. Nvidia is not only buying components. It is helping secure the manufacturing base needed for future AI infrastructure.

For the US, the partnership supports domestic manufacturing around semiconductors, photonics and critical materials. It also reinforces the wider shift toward regionalised supply chains for high-value technology infrastructure.

The Corning-Nvidia partnership shows that AI supply chains are moving beyond chips into optical fibre, photonics and specialty materials. Germanium demand could become a hidden beneficiary as data centres require faster and more resilient optical connectivity.

US solar duties on imports: manufacturers target India, Indonesia and Laos

US solar companies

A new petition seeks US solar duties on imports from India, Indonesia and Laos to curb alleged dumping. A coalition of domestic manufacturers filed AD/CVD cases with Commerce and the ITC. They allege Chinese-backed and Indian firms sell below fair value with illegal subsidies. As a result, US solar duties on imports could expand again after last month’s Southeast Asia tariffs.

Who is behind the push

The Alliance for American Solar Manufacturing and Trade leads the petition. Members include First Solar, Mission Solar Energy and Qcells. Previously, the alliance won duties on Cambodia, Malaysia, Thailand and Vietnam. However, petitioners say producers shifted capacity to Laos and Indonesia. They argue US solar duties on imports must follow those shifts to protect jobs and investments.

The filing targets crystalline silicon PV cells and modules. Petitioners claim antidumping sales under “normal value.” They also cite countervailable subsidies that distort US prices. The first step is an inquiry by Commerce and the ITC. Regulators can then impose provisional tariffs pending final determinations.

How new tariffs could reshape supply chains

New tariffs would raise delivered costs for targeted panels and cells. Meanwhile, they could bolster US factory utilization and planned expansions. Developers may diversify procurement across non-targeted sources to manage risk. As a result, buyers face short-term price volatility and contracting delays.

Trade diversion remains a central concern for policymakers. Petitioners argue enforcement must track ownership and processing routes. Therefore, compliance programs and country-of-origin audits will matter more. Clear guidance on scope will be critical for bankable supply.

The Metalnomist Commentary

Trade policy is steering the solar supply chain as much as technology. If Commerce opens these cases, expect tighter margins and faster localization. Bankable EPCs will hedge with multi-country sourcing while awaiting preliminary duty rates.

U.S. Finalizes Massive Solar Tariffs, Reshaping Southeast Asia’s Export Landscape

US solar

Commerce Department sets duties as high as 3,400% on solar products from Cambodia, Vietnam, Thailand, and Malaysia

The U.S. Department of Commerce has concluded a landmark trade investigation by imposing some of the highest anti-dumping and countervailing duties ever recorded on imported solar panels. The decision targets silicon photovoltaic cells and modules from four Southeast Asian nations: Cambodia, Vietnam, Thailand, and Malaysia.

These duties follow a year-long investigation into allegations that Chinese solar companies, previously subject to tariffs, shifted operations to Southeast Asia in an attempt to bypass U.S. trade regulations. The move is widely regarded as a turning point for the global solar supply chain, with U.S. officials and industry leaders viewing it as a necessary step to restore fair competition.

According to the final determination, some companies—particularly those that failed to comply with the Commerce Department’s requests—will now face duties exceeding 3,400%, an unprecedented figure. For example, four Cambodian firms, including Jintek and ISC, will be subject to this highest tier. In comparison, these same companies were only facing duties of 68% under the preliminary findings issued in October 2024.

On a broader scale, countrywide anti-dumping rates have also surged. Vietnam faces an average rate of 271%, Thailand 111%, and Cambodia 125%. Malaysia, while receiving the lowest general rate—just under 9%—still saw several of its companies slapped with individual duties over 80%, due to non-cooperation during the investigation.

The Commerce Department also imposed steep countervailing duties, which are used to offset the benefits companies receive from government subsidies. Cambodia again ranked highest, with a countrywide rate near 535%, while Vietnam, Thailand, and Malaysia saw rates of 125%, 264%, and 32%, respectively. The lowest countervailing duty—under 15%—was assigned to Hanwha Q Cells Malaysian subsidiary.

These tariffs are expected to take effect in June 2025, pending the final approval of the U.S. International Trade Commission (ITC). In certain cases, particularly in Thailand and Vietnam, duties may apply retroactively if the agencies determine that "critical circumstances" exist—such as import surges meant to beat the implementation timeline.

The ruling stems from a petition filed by the American Alliance for Solar Manufacturing Trade Committee, which includes prominent U.S. solar companies like FirstSolar, Mission Solar, and the U.S. arm of Hanwha Q Cells. The coalition argues that Chinese firms exploited a tariff moratorium enacted by President Biden in 2022 to reroute supply chains and avoid penalties, effectively distorting the market.

Tim Brightbill, legal counsel for the petitioner coalition, welcomed the decision. He emphasized that the tariffs represent a major victory for domestic manufacturers and are essential to encouraging long-term investment in the American solar industry. “These duties will go a long way toward protecting U.S. jobs and restoring a level playing field,” Brightbill said.

Industry analysts believe that the tariffs will have a ripple effect on solar deployment in the U.S., at least in the short term. Project developers who rely heavily on low-cost imported modules may face delays or cost increases. However, domestic producers see the ruling as a long overdue reset that prioritizes manufacturing resilience over low-cost imports.

As the global solar sector undergoes this structural shift, all eyes are on how China and Southeast Asian exporters will respond—and how U.S. clean energy goals will adapt to a more protected domestic market.

China Antimony Market Stabilises as Chenzhou Mining Output Halts Tighten Supply Risk

Antimony

China antimony market conditions have stabilised after prices fell from late March, as production suspensions by major producer Chenzhou Mining raised expectations of tighter domestic supply. The market is now balancing potential output losses against weak downstream demand.

The China antimony market had been under pressure from soft buying in flame retardants and solar glass. But safety-related production halts at Chenzhou Mining subsidiaries have limited further downside and encouraged sellers to watch market developments more closely.

The China antimony market remains fragile because the supply shock is occurring in a demand environment that is still weak. Prices may hold steady in the near term, but a strong rebound looks difficult unless downstream consumption improves.

Chenzhou Mining subsidiaries Xinlong Mining and Zhazixi Mining suspended production and began safety inspections after fatal accidents at two sites. Xinlong Mining has 5,000 t/yr of antimony concentrate capacity, while Zhazixi Mining has 6,000 t/yr of antimony metal capacity.

Output Suspensions Create Short-Term Supply Support

The restart timeline for the suspended operations remains unclear. Some market participants expect the stoppages to last at least one month, potentially cutting overall domestic supply by around 15%.

That scale is important for antimony because China remains a central producer and processor of the metal. Any disruption at a major domestic producer can quickly affect market sentiment, especially when inventories are not evenly distributed across producers and traders.

Antimony metal prices have stabilised at 158,000-162,000 yuan/t ex-works after falling by 9,000 yuan/t since 31 March. Sellers are now less willing to cut offers aggressively while they wait to see how long the production suspensions last.

The supply issue also matters beyond China. Antimony is used in flame retardants, lead alloys, ammunition, cables, batteries, solar glass and other industrial applications. It has become more strategically sensitive as governments reassess critical mineral supply chains.

However, production halts alone do not guarantee a price rally. The market needs stronger buying interest to convert supply risk into sustained upward price movement.

Weak Demand Limits Price Recovery

Demand from flame retardant and solar glass sectors remains soft. This continues to offset the impact of lower production and keeps buyers cautious.

A Hunan-based producer said domestic demand is weak and that some producers still hold hundreds of tonnes of metal stocks. This suggests that inventories are still available, even if fresh supply becomes tighter.

Most antimony metal and trioxide producers appear to be facing similar conditions. Buyers are not rushing to restock because downstream consumption has not improved enough to justify aggressive procurement.

This creates a holding pattern. Sellers have a reason to resist further price cuts because supply may tighten. Buyers have a reason to wait because demand remains weak and existing stocks are still available.

For the antimony value chain, the next price signal will come from the duration of Chenzhou Mining’s suspensions. A short halt may only stabilise the market. A longer shutdown could gradually reduce available supply and strengthen sellers’ position.

Still, demand recovery remains the decisive factor. Without stronger orders from flame retardants, solar glass or other industrial users, the China antimony market is likely to remain stable rather than sharply higher.

The Metalnomist Commentary

The antimony market is showing how supply shocks behave differently when demand is weak. Chenzhou Mining’s output halts have created a floor, but the market needs real downstream restocking before supply risk becomes a stronger price driver.

First Solar plans 3.7GW module plant in Gaffney

First Solar

First Solar plans 3.7GW module plant in South Carolina to expand US solar manufacturing capacity. The company will build the facility in Gaffney, South Carolina. First Solar plans 3.7GW module plant in South Carolina after it announced another US plant in October. The company expects to invest $330mn and start commercial operations in the second half of next year.

Domestic module capacity accelerates toward 17.7GW in 2027

First Solar is scaling domestic output to match rising utility and corporate demand. The added 3.7GW capacity will lift total US production capacity to 17.7GW in 2027. Meanwhile, the company is building a multi-site manufacturing footprint to improve logistics and resilience. Therefore, the new plant strengthens delivery reliability for long-term solar procurement.

The Gaffney investment also signals confidence in sustained US solar deployment. Manufacturers are prioritising repeatable factory designs and faster ramp schedules. However, execution will depend on hiring, qualification, and stable equipment commissioning. As a result, early operational milestones will shape the market’s confidence in the timeline.

US manufacturing footprint widens across multiple states

First Solar plans 3.7GW module plant in South Carolina to add to five existing US facilities. The company already operates plants in Ohio, Alabama, and Louisiana. Meanwhile, a broader footprint can diversify operational risk and improve regional supply coverage. Therefore, the company can support customers across different grid and project corridors.

This expansion also influences the solar supply chain beyond modules. Domestic output can support faster project cycles when logistics and lead times tighten. However, developers still monitor input costs, permitting, and interconnection delays. As a result, manufacturing expansion works best when grid buildout keeps pace.

The Metalnomist Commentary

US module capacity is shifting from policy ambition to industrial reality. Meanwhile, scale manufacturing can stabilise pricing and shorten delivery times. Therefore, winners will be the firms that ramp reliably and meet bankability standards.

T1–Corning US solar production partnership targets stable domestic supply

US solar

T1–Corning US solar production will anchor cells and modules in America. The partners plan a Michigan–Austin–Dallas supply chain. T1–Corning US solar production uses Corning’s hyper-pure polysilicon and wafers. T1’s 5GW Austin cell facility starts by late 2026. T1–Corning US solar production then feeds T1’s Dallas module line. The strategy pursues predictable US solar components amid new tariffs.

US manufacturing plan links Michigan wafers to Austin cells

Corning will supply wafers and polysilicon from Michigan. T1 will convert these inputs at its $850mn Austin plant. The facility targets 5GW of cell capacity. Production should begin by end-2026. Cells will ship to Dallas for module assembly. Therefore, logistics remain entirely inside the US. This reduces import risk and lead times.

Policy tailwinds and risk factors for domestic solar

US trade actions tightened import conditions this year. Commerce imposed AD/CVD on key Southeast Asian suppliers. A Section 232 probe now reviews polysilicon import security. Therefore, domestic output gains relative certainty. However, ramp risk still includes yields and qualifications. Bankable offtakes and tax credits will shape execution.

The Metalnomist Commentary

This partnership aligns manufacturing with policy and grid needs. Yet scale economics hinge on high yields and steady wafer supply. Watch contract visibility and Austin ramp curves through 2027.

Hoshine Silicon Output Falls as China Photovoltaic Demand Slows

Hoshine

Hoshine silicon output fell sharply in 2025 as weaker photovoltaic demand weighed on China’s largest silicon metal producer. The company produced around 1.45mn t of silicon metal during the year, down 22.3% from 2024.

Hoshine silicon output declined as downstream polysilicon and photovoltaic markets lost momentum. Sales also fell by 10.1% on the year to 1.11mn t, reflecting softer consumption from key solar supply-chain customers.

Hoshine silicon output remains important because the company is a major force in China’s silicon metal market. Its production trends provide a clear signal for supply conditions across aluminium alloys, organosilicon, polysilicon and photovoltaic materials.

China’s wider silicon metal production also weakened. National output fell by 11% on the year to around 4.20mn t in 2025, showing that the slowdown was not limited to one producer.

Polysilicon Weakness Hits Silicon Metal Demand

Polysilicon production fell sharply in 2025, reducing one of the key demand channels for silicon metal. China produced around 1.33mn t of polysilicon during the year, down 27.8% from 2024.

This decline reflects pressure across the solar manufacturing chain. Photovoltaic growth continued, but the pace slowed compared with the previous year.

China’s newly installed photovoltaic capacity reached around 31.7GW in 2025, up 14% from a year earlier. However, this was well below the 28% growth recorded in 2024.

That slowdown matters for silicon producers. Silicon metal is a critical feedstock for polysilicon, which is then used in solar wafers, cells and modules.

When polysilicon output falls, demand for silicon metal weakens quickly. Producers then face lower sales, inventory pressure and weaker pricing power.

Hoshine’s 2025 results show how tightly silicon metal is linked to solar-sector cycles. Even large producers with scale advantages are exposed when downstream photovoltaic demand slows.

Capacity Remains Large Despite Softer Market Conditions

Hoshine still operated at high capacity utilisation despite lower output. The company has 1.22mn t/yr of designed silicon metal capacity, with utilisation reaching 119.2% in 2025.

This indicates that Hoshine continued producing above nameplate capacity, even as output fell from the previous year. The company remains a dominant supplier in China’s silicon metal market.

Hoshine also had 1.73mn t/yr of designed organosilicon capacity by the end of 2025. Organosilicon remains another major downstream channel for silicon metal, serving construction, electronics, automotive, industrial and consumer applications.

The company also had 50,000 t/yr of polysilicon capacity and a further 350,000 t/yr under construction. This shows that Hoshine is still investing in downstream integration despite short-term market weakness.

The expansion strategy carries both opportunity and risk. Integrated silicon-to-polysilicon capacity can improve value capture when solar demand recovers. However, it can also increase exposure to oversupply if polysilicon markets remain weak.

For China’s silicon industry, the key issue is balance. Producers must manage large capacity bases while downstream photovoltaic growth becomes less explosive than in previous years.

The Metalnomist Commentary

Hoshine’s lower silicon output shows that solar-sector growth is no longer strong enough to absorb every upstream expansion. China’s silicon market now faces a more selective phase where cost control, downstream integration and demand timing will determine profitability.

ReElement Germanium Recovery Signals New US Supply for Critical Minerals

ReElement

ReElement germanium recovery has achieved 3N–5N purity from recycled and ore feedstocks. The US refiner produced 99.9–99.999pc germanium and plans rapid scale-up. ReElement germanium recovery directly addresses a critically tight non-Chinese supply chain.

Scaling high-purity germanium in the US

ReElement germanium recovery will expand at the Marion, Indiana facility and partner sites. The company targets higher output over the next year. As a result, US manufacturers gain a domestic source of high-purity germanium. This supports defense, telecom and solar supply chains.

Tight global supply creates strategic opening

Global germanium supply remains tight after Chinese export controls. Beijing halted shipments to the US in 2024. Therefore, alternative refining and recycling capacity matters more than ever. ReElement’s multi-feedstock platform reduces dependence on single-country supply.

US demand spans infrared optics, fiber optics and space-grade solar cells. Meanwhile, defense programs require traceable, high-purity inputs. A 4N–5N product slate can meet stringent procurement standards. Price volatility may ease as diversified supplies emerge.

Recycling strengthens material security and sustainability. The process captures germanium from industrial scrap and end-of-life components. Consequently, metallurgical yields rise while waste declines. Circular flows lower import risk and carbon intensity.

Downstream buyers seek assured quality and delivery. ReElement’s roadmap signals qualification runs and offtake discussions. In turn, OEMs can lock in compliant material ahead of program ramps. Indiana’s growing critical-minerals hub supports rapid scale and logistics.

The Metalnomist Commentary

This milestone is small in tonnage but large in leverage. If ReElement converts pilot wins into reliable, multi-feedstock output, US germanium risk premia should narrow. Watch for long-term offtakes from infrared, satellite and grid-solar segments as validation.

Rio Tinto Explores Gallium Extraction in Canada Amid Global Supply Shift

Rio Tinto

Global mining giant Rio Tinto is investigating the feasibility of extracting gallium from its operations in Canada, positioning itself to play a critical role in the North American supply chain for this strategically significant metal. The company plans to establish a demonstration plant in Quebec's Saguenay-Lac-Saint-Jean region, which could eventually produce up to 40 million tonnes of gallium annually, accounting for 5-10% of global output.

Leveraging Bauxite for Gallium Extraction

The gallium extraction initiative focuses on utilizing the gallium present in the bauxite ore processed at Rio Tinto's alumina refinery in Quebec. This approach highlights the company’s innovation in valorizing existing materials in its production processes.

During the project's initial phase, Rio Tinto will evaluate the technology required to extract gallium. If successful, the company aims to build a demonstration facility capable of producing 3.5 million tonnes annually in its early stages, with plans to expand capacity as demand grows.

Gallium, a critical metal primarily used in the semiconductor and solar panel industries, has seen a surge in strategic importance following China's decision to restrict exports of gallium and other vital minerals to the U.S. As the world's largest gallium producer, China's actions underscore the need for alternative sources, making Rio Tinto's initiative a pivotal development.

Strengthening North American Critical Mineral Supply

Rio Tinto’s project aligns with broader efforts to bolster the North American supply chain for critical and strategic minerals, ensuring a more resilient and independent supply network. Rio Tinto Aluminium’s chief executive, Jerome Pecresse, emphasized the project’s role in addressing geopolitical and supply chain challenges in the global critical metals market.

With the growing reliance on gallium for advanced technologies, including semiconductors and renewable energy solutions, Rio Tinto’s project represents a significant step forward in diversifying the global supply of this vital resource.
