GTP Tungsten Oxide Stockpile Expansion Strengthens US Defense Supply

GTP Tungsten & Powders

GTP tungsten oxide stockpile plans will expand US access to one of the most strategically sensitive defense metals. Global Tungsten and Powders plans to raise tungsten oxide production capacity at its Towanda, Pennsylvania, plant to about 12,000 t/yr.

The GTP tungsten oxide stockpile will support US defense and critical industries, with initial deliveries expected later this year. The company did not disclose the exact volume dedicated to the reserve.

The GTP tungsten oxide stockpile is significant because tungsten is essential for armour-piercing ammunition, aircraft engine components, electronics, hard metals and other high-performance applications. Defence currently accounts for about 10% of global tungsten demand, but that share is rising as military budgets expand.

GTP, part of Austria’s Plansee group, already has around 10,000 t/yr of tungsten oxide capacity, although output can vary by about 15% depending on operating conditions. The planned expansion would give the US a stronger domestic platform for strategic tungsten oxide supply.

Recycling-Based Supply Supports Traceability and Security

The stockpile will use tungsten oxide sourced from recycled scrap and concentrates. This structure is important because US strategic materials procurement increasingly requires clear sourcing, traceability and supply-chain security.

Recycling is already central to GTP’s Towanda operation. Recycled material accounted for the majority of supply in 2025, when the plant recorded a recycling rate of 90%.

This gives the project a stronger compliance profile. Tungsten supply chains are exposed to geopolitical risk, concentrated processing and origin scrutiny, so recycled feedstock can help reduce dependence on higher-risk primary sources.

Tungsten recycling also supports industrial resilience. Scrap recovery can preserve valuable metal units inside the US system while reducing exposure to foreign concentrate availability.

For defense users, the key requirement is not only tonnage. They need reliable, traceable and qualified material that can be converted into powders, carbides, alloys and components without supply interruption.

The Towanda expansion therefore addresses a strategic gap. It does not only increase tungsten oxide capacity; it creates a more controlled domestic reserve tied to recycled and traceable inputs.

Stockpiling Moves From Emergency Buffer to Industrial Tool

Plansee US Holding has formed a joint venture with Manhattan Five to establish the stockpile. Manhattan Five will oversee warehousing, logistics and long-term asset management, while Plansee will lead production growth and supply.

The structure separates metal production from storage and asset management. That distinction matters because strategic stockpiles require more than buying material. They need inventory systems, logistics, inspection, rotation policies and long-term custody control.

The Defense Logistics Agency manages strategic and critical material procurement for the National Defense Stockpile. This system supports military and federal customers that need access to critical materials during supply disruptions.

The GTP project aligns with broader US priorities and could qualify for support from the Department of Defense, Department of Energy or the Export-Import Bank of the United States.

Washington is also preparing Project Vault, a proposed $12bn critical minerals stockpile for US manufacturers. The programme would be funded by $2bn in private capital and a loan.

The broader policy direction is clear. The US is moving from passive dependence on global tungsten markets toward active supply-chain positioning through stockpiles, domestic processing, recycling and public-private financing.

For tungsten markets, this could tighten competition for clean feedstock, especially recycled scrap and compliant concentrates. It may also raise the strategic value of processors that can meet US sourcing and traceability rules.

The Metalnomist Commentary

GTP’s tungsten oxide expansion shows that US stockpiling is becoming more industrially sophisticated. The strategic advantage will come not from holding material alone, but from linking stockpiles to recycling, domestic processing and qualified defense supply chains.
