Key facts
- A Chinese rare earth export ban could force defense and civilian sectors to compete for limited domestic supply.
- REalloys aims to establish the Western Hemisphere's first commercial-scale heavy rare earth metallization platform.
- The U.S. aims to ban Chinese-origin rare earths in weapons systems by January 1, 2027.
- REalloys secured feedstock agreements in Greenland, Brazil, Montana, Wyoming, and Kazakhstan.
- Rio Tinto is developing lithium production in Argentina and scandium production in Quebec.
A potential Chinese blockade of rare earth exports to the United States could have severe repercussions for both the defense sector and the broader civilian economy. The U.S. Pentagon has set a January 1, 2027 deadline to ban Chinese-origin rare earths in its weapons systems, a move that defense manufacturers warn may not be achievable with current supply chain readiness. REalloys, a company developing a significant heavy rare earth metallization facility outside China, is a key player in the race to establish domestic capacity. The company has secured multiple feedstock sources and is working to integrate the entire manufacturing chain from raw materials to finished magnets. Recent disruptions in Japan and Europe have already shown how quickly inventories can dwindle, leading to rationing, product redesigns, and temporary production suspensions. In the U.S., manufacturers with the thinnest inventories and highest reliance on high-performance magnets, particularly in the automotive, industrial motor, robotics, and aerospace sectors, would be the first to face shortages. China's dominance in rare earth supply chains, including yttrium, poses a significant challenge, as the U.S. currently relies entirely on imports for commercial-scale primary yttrium production. Beyond rare earths, other critical minerals like copper, lithium, and scandium are also crucial, with companies like Rio Tinto and BHP Group expanding their roles in supplying these materials.
