China Tightens Rare‑Earth Export Controls, Spurring Diversification

Beijing issued six export‑control notices in October 2025 that tighten licensing for rare earths, permanent magnets, separation reagents, production equipment, and recycling technologies.

The measures extend regulatory oversight beyond ores to processing methods and machinery, giving authorities fine‑grained tools to slow, scrutinize, or redirect critical material flows. The moves followed the U.S. Bureau of Industry and Security’s new Affiliates Rule, which expands U.S. export jurisdiction to companies with 50% Chinese ownership—prompting Beijing to demonstrate its own leverage.

China still accounts for roughly 70% of global rare‑earth mining and about 90% of refining capacity, so regulatory shifts have immediate technical and commercial impact. Companies in automotive, defense and clean energy sectors now face competing, sometimes incompatible rulebooks, increasing compliance costs and supply uncertainty.

At the same time, policy responses and industry investment are accelerating supply‑chain diversification: refinery builds and financing in Australia and Canada, magnet recycling growth in Japan, and U.S. defense contracts to shore up domestic capability. That fragmentation reduces China’s absolute leverage over time, creating both near‑term disruption and medium‑term investment opportunities in upstream mining, processing, and recycling technologies.
