• China controls 60% of global critical mineral production and 85% of processing capacity, per U.S. threat assessment.
  • Recent export restrictions on gallium, germanium and graphite highlight supply chain vulnerabilities.
  • U.S. accelerating efforts to diversify sources through domestic investment and allied partnerships.

China's Market Stranglehold

China's grip on critical mineral supply chains has tightened to alarming levels, with the country now controlling 99% of battery-grade graphite production and over 80% of refined magnet rare earths, according to the newly released U.S. Annual Threat Assessment Report. The dominance extends across multiple strategic materials, including 70% of refined cobalt and 40% of refined copper production - giving Beijing unprecedented leverage in global markets.

"This isn't just about economics - it's become a clear national security issue," said one U.S. official familiar with the report who requested anonymity. The assessment comes as China implements fresh export controls on graphite, following similar restrictions on gallium and germanium last summer.

Washington's Countermeasures

The Biden administration has quietly accelerated efforts to break China's stranglehold through a three-pronged strategy: export controls on advanced technologies, subsidies for domestic processing facilities, and "friend-shoring" partnerships with Australia and Canada. Recent moves include fast-tracking permits for rare earth mines and allocating Defense Production Act funds for lithium processing plants.

Industry analysts note the challenges remain daunting. "Even if we ramp up mining, China still holds most of the world's processing know-how," noted a metals strategist at a major investment bank. "Building that expertise will take years and billions in capital."

Shifting Global Dynamics

While China's share of raw material production may decline from 62% to 28% by 2035 according to some projections, its processing dominance appears secure for the foreseeable future. The report highlights how Chinese firms have locked in long-term supply agreements across Africa and South America, while maintaining cost advantages through vertically integrated operations.

European and Asian manufacturers are feeling the pinch most acutely. "We're seeing clients pay 30-40% premiums for non-Chinese graphite that meets battery standards," shared a procurement officer at a Korean battery maker, speaking on condition of anonymity. The situation has sparked renewed interest in recycling programs and alternative battery chemistries among automakers.

Editor's Note: An earlier version understated China's share of rare earth processing. The correct figure is 85-90% globally.
