U.S. Defense Supply Chains Face Rare Earth Crunch Ahead of 2027 Deadline

The urgency stems from DFARS procurement regulations taking effect January 1, 2027, which mandate that U.S. defense supplies be entirely free of Chinese rare earth content. This policy shift arrives alongside China’s aggressive move to weaponize mineral exports; for instance, after Beijing restricted antimony in 2024, prices surged 2,600% and U.S. shipments plummeted by 97%. Similar patterns now threaten heavy rare earths, which are vital for drone motors, missile guidance systems, and fighter jet engines.

Companies such as REalloys are positioning themselves to fill this void by establishing supply chains independent of Chinese feedstock and technology. The market is already reflecting this bifurcation, with non-Chinese dysprosium and terbium trading at three to four times domestic Chinese prices. While industry players like MP Materials, USA Rare Earth, and Critical Metals Corp work to scale domestic production, the Pentagon’s annual demand for rare earth magnets is projected to triple by 2030, leaving a narrow window for contractors to certify their supply lines before the upcoming deadline.
