Creates a U.S.-led Critical Minerals Security Alliance and gives the U.S. Trade Representative authority to negotiate membership agreements with partner countries to secure supply chains for critical minerals used in defense, energy, and advanced manufacturing. It imposes higher import duties on critical minerals from designated “countries or entities of concern,” directs those duty receipts into a new Treasury trust fund, and automatically channels trust funds to the Department of Energy, the Department of Defense, and the U.S. International Development Finance Corporation to support domestic mining, processing, and related manufacturing and investment.
