The Rare Earth Magnet Security Act of 2025 aims to encourage the domestic production of high-performance rare earth magnets by providing tax credits to manufacturers. The main goal is to strengthen the U.S. supply chain for these critical materials, which are essential for various technologies, including electronics, renewable energy, and defense systems. Key provisions of the Act include a tax credit for manufacturers based on the amount of rare earth magnets they produce and sell. Specifically, manufacturers can receive $20 per kilogram for magnets produced in the U.S.
