Why It Matters
China's systematic chokehold on critical minerals is forcing Congress to act. Over the past 18 months, Beijing has weaponized its dominance of rare earths, gallium, and other materials essential to defense and semiconductors, imposing export restrictions that have rippled through allied supply chains. The House Energy and Commerce Subcommittee on Environment scheduled for June 24 hearing to examine whether domestic mineral recycling legislation can reduce American dependence on a geopolitical adversary.
The Big Picture
The stakes are stark. Starting in December 2025, China denied export licenses to companies with any affiliation to foreign militaries, including those of the United States. The move followed earlier restrictions on heavy rare earths and permanent magnets in April 2025, then a broader expansion in October 2025 targeting defense and semiconductor users. By January 2026, China had begun restricting rare earth exports to Japanese companies, signaling a widening effort to leverage supply chains as a coercive tool.
The Trump Administration has responded with urgency. President Donald Trump issued a proclamation in January 2026 directing negotiations to address national security concerns tied to critical mineral imports, and Vice President JD Vance unveiled a proposal in February to marshal allies into a preferential trade bloc for critical minerals, complete with coordinated price floors aimed at loosening China's grip.
But the administration's diplomatic and trade efforts are only part of the equation. Congress is now turning to a different lever: the domestic supply side. The critical mineral recovery hearing will focus on how recycling discarded electronics and industrial waste can reduce dependence on new mining and, by extension, on China.
The Department of Energy has already begun investing in the concept. In April 2026, it selected five organizations to restart domestic primary gallium recovery, and Arizona State University published research in June 2026 on recovering gallium and indium from discarded LED light bulbs and lamps.
The Hearing on Critical Mineral Recovery
The subcommittee will examine domestic mineral recycling legislation on Wednesday, June 24. Two bills are expected to feature prominently: the Spent Petroleum Catalyst Recycling and Critical Minerals and Metals Recovery Exemption Act, which would exempt spent petroleum refining catalysts from hazardous waste regulations, and the Securing America's Mineral Supply Act, sponsored by Rep. Gary Palmer (R-AL), a member of the subcommittee itself.
