China suspends rare‑earth exports, 90% share
- China put export controls on seven medium and heavy rare earths on April 4, 2025, and shipments effectively stalled as exporters waited for licenses. - The bottleneck hit dysprosium, terbium, samarium and related magnets — materials China dominates in processing and magnet-making, near 90% or higher. - That matters because motors, missiles, EVs and robots use them, and alternative supply chains still take years to build.
Rare earths are not actually rare in the “running out tomorrow” sense. The problem is processing — and magnets. That is where China built the choke point. In April 2025, Beijing imposed export controls on seven medium and heavy rare earth elements and related products, and shipments then slowed or stopped while companies waited for the new license system to function. ### What exactly did China do? China’s Ministry of Commerce and customs agency announced controls on April 4, 2025 covering samarium, gadolinium, terbium, dysprosium, lutetium, scandium, and yttrium, plus related forms and compounds. This was not a blanket permanent ban written that way on paper. It was a licensing regime. But in practice, when a government suddenly says “you now need approval” and the approval pipeline is not ready, cargo sits. (english.mofcom.gov.cn) That is why so many descriptions called it a suspension or halt. ### Why do these particular elements matter? Because these are the ingredients that make high-performance permanent magnets survive heat and stress. Dysprosium and terbium are the big ones for high-coercivity magnets — the kind used in EV drivetrains, wind turbines, drones, missiles, and other systems where failure is not an option. Samarium also matters for samarium-cobalt magnets used in aerospace and defense. These are tiny inputs by volume, but they decide whether the motor or guidance system works at all. (english.mofcom.gov.cn) ### Why does everyone keep saying “90%”? Because the real dependence is not just mining. China’s strongest position is downstream — separation, refining, metal-making, and magnet production. Recent assessments put China near 90% of rare-earth processing for some key segments, and around 90%-plus in rare-earth magnet manufacturing. So even if ore exists elsewhere, the step that turns it into usable industrial material is still concentrated in China. (hklaw.com) Basically, the mine is not the bottleneck — the chemistry plant and magnet factory are. ### Was this aimed only at the U.S.? No — and that is the part many people miss. Reporting at the time said shipments were being blocked or delayed for multiple destinations, not just the United States, because the licensing system itself was the constraint. That meant Japanese, German, and other buyers were exposed too. A chokepoint this concentrated does not need a formal embargo on every country to create global disruption. Administrative friction is enough. (iea.org) ### Why did the impact show up so fast? Because many manufacturers do not hold huge stockpiles of specialized magnet materials. These are niche inputs with long qualification cycles, and some defense and industrial uses cannot just swap in a different supplier next week. Think of it less like losing access to steel and more like losing a specific semiconductor tool chemical — tiny line item, massive production consequence. CSIS described the 2025 controls as exposing a major U.S. and allied supply-chain vulnerability. (yahoo.com) ### Can the rest of the world just build around China? Eventually, partly. But not quickly. New mines help less than people think if separation, alloying, and magnet sintering still sit elsewhere. The U.S. and partners have been throwing money at domestic projects, offtake guarantees, and deals with Australia, Japan, Malaysia, and others. The catch is timing — building a resilient chain for heavy rare earths and magnets is a multi-year industrial project, not a quarter-to-quarter fix. (csis.org) ### Did anything ease after the initial shock? Some signs did emerge that specific exports were getting approved later, including one aerospace-related material shipped in large quantities in March 2026. But that is not the same thing as the chokepoint disappearing. It just shows Beijing can tighten or loosen flows selectively while keeping the licensing lever in place. (csis.org) ### Bottom line The story is not “China mined 90% of rare earths.” The story is harsher than that. China controls the hard middle of the chain — the processing and magnets — and that is why an export-control notice turned into a global industrial scare almost immediately.
