The volatility in antimony, where prices jumped from $1,400 to $38,000 per ton, serves as a blueprint for the potential weaponization of rare earth metals. China’s systematic move to restrict exports of gallium, germanium, and now heavy rare earth elements has prompted a scramble for non-Chinese supply chains. Companies like REalloys (NASDAQ: ALOY) are positioning themselves as alternatives, securing offtake agreements in North America and developing metallization facilities in Euclid, Ohio, to bypass Chinese-origin inputs.

The 2027 Procurement Shift

The urgency is driven by the Pentagon's new DFARS procurement rules, which will ban Chinese-origin rare earths from U.S. defense supply chains by January 1, 2027. This mandate forces major contractors, including Lockheed Martin and Northrop Grumman, to overhaul their sourcing for components in the F-35 fighter jet and the B-21 Raider. As demand for rare earth magnets is projected to triple by 2030, the market is splitting into a two-tier system where non-Chinese materials trade at a significant premium. With terbium prices already up 103% this year, the industry faces a narrow window to establish independent production before the regulatory cutoff makes current reliance on Chinese materials untenable.
