Energy Fuels’ Terbium Oxide Wins Key Japan Magnet Qualification

Energy Fuels Inc. has achieved a major milestone in the rare earth elements market after its terbium oxide received full qualification from one of Japan’s largest manufacturers of rare earth permanent magnets outside China.

The U.S.-based producer announced that terbium (Tb) oxide manufactured at its White Mesa Mill in Utah has successfully met the Japanese manufacturer’s technical specifications. The customer has approved the material for commercial production of rare earth permanent magnets, with no additional qualification or validation required.

The approval represents an important step for Energy Fuels as it seeks to establish itself as a reliable supplier of heavy rare earth elements to markets outside China. Terbium is considered one of the most strategically important and valuable rare earth elements because of its limited availability and critical role in advanced magnet technologies.

Terbium improves the heat resistance and performance of high-strength neodymium-iron-boron (NdFeB) permanent magnets. These magnets are widely used in electric vehicles, robotics, advanced electronics, aerospace systems, defense equipment and other high-technology applications.

According to Benchmark Mineral Intelligence, terbium oxide currently commands a market price of around $5.5 million per tonne on a CIF Europe basis. The high value reflects the element’s extreme scarcity and limited production capacity in Western markets.

Energy Fuels said the qualification further validates its rare earth processing capabilities and strengthens efforts to develop a more secure and diversified supply chain for critical materials. The company has already secured qualifications for its neodymium-praseodymium (NdPr) and dysprosium (Dy) oxides for rare earth permanent magnet applications.

The company also expects its position in the global rare earth industry to expand through its proposed acquisitions of Australian Strategic Materials (ASM) and Vacuumschmelze (VAC). Once these transactions close, Energy Fuels expects to establish a vertically integrated mine-to-magnet supply chain across the United States and Europe.

Its White Mesa Mill is expected to play an important role in this strategy, with NdPr, terbium and dysprosium oxides forming key components of the planned supply chain.

The latest qualification could also strengthen Energy Fuels’ commercial relationships with Japanese manufacturers and support future demand for its heavy rare earth products. More broadly, the development highlights growing efforts among Western economies and Asian allies to diversify rare earth supplies and reduce dependence on concentrated sources.

Product and Chemical Commodity Price Impact

The qualification is bullish for Energy Fuels’ terbium oxide business because commercial approval from a major Japanese magnet producer validates product quality and could unlock additional demand. Higher adoption may improve Energy Fuels’ sales prospects and strengthen the long-term value of its heavy rare earth portfolio. For the broader rare earth market, the immediate price impact may remain limited because the qualification does not create substantial new supply. However, stronger Western production could gradually reduce supply-chain risk. Terbium and dysprosium prices may remain firm due to scarcity and strategic demand, while NdPr prices could gain moderate support from expanding permanent-magnet applications.
