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 primary goal is to strengthen the U.S. supply chain for these critical materials, which are essential for various technologies, including electric vehicles, renewable energy systems, and defense applications. Key provisions of the Act include the establishment of a tax credit for the production of rare earth magnets. Manufacturers can receive a credit of $20 per kilogram for magnets produced in the U.S.
