Restoring American Mineral Security Act of 2025

This bill establishes the Critical Minerals Security Alliance, an international partnership to build a reliable supply chain for critical minerals by creating a network of countries that agree to increase duties on minerals from China and other "foreign countries of concern" while receiving duty-free access to the U.S. market. It requires countries joining the alliance to commit to higher tariffs on minerals from China and to share information about their mineral production capacity. The bill creates a trust fund using duties collected on minerals from China to support U.S. projects for mining, processing, and manufacturing critical minerals, with funds allocated to the Department of Energy, Department of Defense, and U.S. International Development Finance Corporation. It mandates annual reporting to Congress on alliance progress and sets specific requirements for countries to join the alliance, including commitments to address unfair trade practices.
