US rare earth supply chain faces tight 2027 defence procurement deadline
:format(auto):focal(center))
US defence suppliers have just over two months to prove compliant rare earth supply chains before Defense Federal Acquisition Regulation Supplement (DFARS) restrictions extend to the full mine-to-magnet chain on 1 January 2027. Domestic and allied rare earths separation capacity will not meet demand by that deadline. Existing Department of War (DoW) restrictions on rare earth magnet and tungsten purchases from China are to be expanded from where materials are melted or produced to mining, refining, and separation from 1 January 2027. The rules were first set out in 2021, but the deadline for implementation is approaching. Those who fail to comply risk liabilities or contract termination.
