Chile Lithium Carbonate Exports Lead Global Trade Despite Argentina’s Rapid Rise

Chile Lithium

Chile lithium carbonate exports remained the largest globally in 2025, although the country lost significant market share as Argentina rapidly expanded production. Chile shipped almost 225,750t of lithium carbonate worth $1.9bn, accounting for 62.2% of global exports.

Chile lithium carbonate exports had represented around 78% of global trade in 2024. The fall to 62.2% represents a 15.8 percentage-point decline in only one year and signals a major change in South America’s lithium supply structure.

Chile lithium carbonate exports still give the country a dominant position in battery raw materials, but Argentina is emerging as a much stronger competitor. Argentina exported 102,842t, equivalent to roughly 28-30% of global lithium carbonate flows.

Chile also maintained its position as the world’s leading copper exporter. Chilean producers shipped 5.7mn t of copper in 2025, generating $53.6bn in export revenue and accounting for 16.2% of global exports.

Argentina Changes the Balance of South American Lithium Supply

Argentina’s rapid increase in lithium carbonate exports is reducing Chile’s historical dominance of the market. The shift reflects new production capacity entering the Argentine lithium sector and creating a second major South American export platform.

This competition has strategic implications for battery manufacturers. Greater supply diversification between Chile and Argentina can reduce dependence on a single producing country and provide buyers with more procurement options.

For Chile, the challenge is maintaining competitiveness while expanding production and moving toward higher-value lithium processing. Resource quality alone will not guarantee continued market dominance as neighbouring projects add capacity.

The change also matters for pricing. A broader supply base can increase competition between producers, especially during periods when lithium markets are already well supplied.

At the same time, Chile remains a major strategic supplier because of its established operations, infrastructure and long experience in lithium carbonate production.

The market is therefore moving from overwhelming Chilean dominance toward a more balanced South American structure, with Argentina becoming increasingly important to global battery supply chains.

Copper Leadership Gives Chile a Second Strategic Advantage

Chile’s copper position remains even more deeply established. The country has held the leading global export position for decades and shipped 5.7mn t in 2025.

State-owned Codelco remains central to the sector, alongside major international miners operating across the country’s large porphyry copper deposits.

Copper export revenue of $53.6bn demonstrates the metal’s importance to Chile’s economy. It also gives the country exposure to structural demand from power grids, renewable energy, electric vehicles, data centres and industrial electrification.

The combination of copper and lithium gives Chile an unusually strong position in the energy transition supply chain. Few countries are leading exporters of both a major electrical metal and a core battery material.

However, the two markets face different competitive dynamics. Chile’s copper leadership remains firmly established, while lithium faces faster capacity growth from Argentina and other emerging producers.

Chile’s long-term industrial opportunity therefore lies not only in maintaining export volumes, but in capturing more value through processing, technology and downstream manufacturing connected to both metals.

The Metalnomist Commentary

Chile remains a critical supplier of both copper and lithium, but its lithium dominance is becoming less absolute. Argentina’s rise shows that future leadership in battery materials will depend increasingly on capacity growth, processing economics and speed of project development.
