Neodymium-iron-boron magnets are among the most critical materials affected by the new DFARS 252.225-7052 requirements, and they present one of the clearest examples of supply chain vulnerability.
China currently dominates global production of neodymium-iron-boron magnets, controlling approximately 80-90% of the world’s supply. This heavy reliance on a single country creates significant national security and supply chain risks for the United States.
These high-performance magnets are essential in many defense applications, including electric motors, actuators, sensors, and guidance systems. You’ll find them in everything from drone motors and radar components to precision-guided munitions and electric vehicle systems used in support roles.
Because of their importance and the concentration of supply in China, the new DFARS rules place special emphasis on tracing the full production chain for these magnets — from mining and refining through final magnet manufacturing.
The strategic importance of onshoring or securing allied sources for neodymium magnets cannot be overstated. Reducing dependence on a potential adversary for materials critical to our most advanced systems is essential for maintaining technological superiority and operational readiness.
For defense contractors and suppliers, this means that even small magnets in commercial components can trigger full compliance requirements once integrated into a defense end item.
At RavenClear, we help companies understand their exposure to neodymium and other critical materials and develop practical compliance strategies that meet current requirements while preparing for future expansion of these rules.
