China permanent magnet controls squeeze motor supply as alloy research stalls
Export licensing and refining bottlenecks keep electric drive makers tied to standard rare-earth grades despite laboratory trials of multi-element alloys.

China's Ministry of Commerce maintained strict export licensing on rare-earth permanent magnets as automotive motor and industrial drive manufacturers assessed the limits of multi-principal high-entropy alloy research, according to ministry regulatory records on Sept. 1, 2026.
The International Energy Agency reported on June 1, 2026 that China controls 91% of global rare-earth refining capacity and 94% of sintered permanent-magnet production. That processing concentration leaves Western powertrain developers and robotics suppliers dependent on Chinese metal converters and sinter facilities for high-performance drive components.
