As of August 19, 2026, Energy Fuels announced that its terbium oxide, a heavy rare earth used to improve the performance and heat resistance of high-strength permanent magnets, has passed qualification for commercial use by one of Japan’s largest permanent-magnet manufacturers. [1] According to Energy Fuels, the approval is significant because terbium is a relatively scarce and strategically important material, and these magnets are used in technologies including EVs, robotics, advanced electronics, aerospace and defense. It also gives Energy Fuels another validated customer as it works to build a non-Chinese supply chain for rare earth materials. The company has already qualified its neodymium-praseodymium and dysprosium products with customers and is pursuing acquisitions that would expand its capabilities from rare-earth processing into magnet production. Energy Fuels believes that for Japan, the development supports broader efforts to diversify critical-mineral supplies away from China, which currently dominates much of the global rare-earth processing and permanent-magnet industry. Energy Fuels intends to make progress toward establishing a more diversified U.S.- and Japan-linked supply chain for the materials needed in advanced manufacturing and clean-energy technologies.
