The Magnets Value Chain Support Act of 2026 aims to bolster the production and use of permanent magnets in the United States, reducing reliance on foreign sources, particularly China, for essential materials critical to various technologies, including electric motors, generators, and defense systems. This legislation addresses national security and economic concerns by promoting domestic manufacturing. The act introduces a tax credit system to incentivize the domestic production of permanent magnets, magnet metals, and rare earth oxides.
