China Holds the Rare-Earths Valve; the West Answers With Price Floors and Equity
Beijing's April-2025 export-licensing regime on heavy rare earths is still running in 2026. The response — U.S. and allied price floors, a Pentagon equity stake, long-dated offtakes — is rewriting how critical-mineral supply gets built, and seeding a new class of disputes.
What happened
In April 2025, amid the U.S.–China trade war, China imposed export licensing on seven medium and heavy rare earths — including dysprosium and terbium — plus the magnets made from them. A later, broader expansion was suspended under a November-2025 truce, but the core April-2025 regime remains active in 2026: every shipment still needs case-by-case approval.
China controls roughly 90% of rare-earth processing and the overwhelming majority of heavy-rare-earth separation, so the licensing valve effectively sets global availability. The Western response has been industrial policy at speed: a U.S. Department of Defense equity stake and price floor in MP Materials (July 2025); two separate US$110/kg price floors and long-dated offtakes for Lynas from the U.S. and Japan (March 2026); and an Australian critical-minerals strategic reserve.
Why it matters for dispute formation
Two dispute surfaces are opening at once. The first is state-to-state: export restrictions on raw materials have been found inconsistent with WTO rules before, and a discretionary licensing regime invites the same challenge — even as the appetite to pursue WTO remedies is itself uncertain.
The second is newer and closer to the operator. When governments become price-setters and shareholders, they import a web of subsidy, countervailing-duty, state-aid and procurement-law exposure into what used to be ordinary offtake. And downstream, every throttled shipment is a potential force-majeure or supply-contract dispute. The chokepoint is geopolitical; much of the litigation it seeds is commercial and regulatory.
Who's exposed
The only commercial producer of separated heavy rare earths — dysprosium and terbium — outside China, exactly the elements Beijing placed under export licensing. Secured US$110/kg NdPr price floors from both the U.S. Department of War and Japan's JARE (to 2038) in March 2026; its U.S. Seadrift plant stalled, leaving separation concentrated in Malaysia.
In July 2025 the U.S. Department of Defense took a ~15% equity stake plus a US$110/kg NdPr price floor — making the government MP's largest shareholder, a landmark in industrial policy.
Automakers, defence primes and electronics makers face licensing friction and price spikes on Dy/Tb — both on China's control list — where ex-China supply is scarce.
The historical parallel · WTO — China – Rare Earths (DS431, 2014)
A decade ago a WTO panel found China's rare-earth export quotas and duties inconsistent with its obligations. The instrument changed; the leverage did not. The 2025–26 licensing regime is the same chokepoint expressed a different way — and a reminder that a legal win does not, by itself, rebuild a supply chain.
What to watch
- Whether the November-2025 truce holds, or the broader October-2025 controls snap back.
- Heavy-rare-earth (Dy/Tb) pricing and the spread between Chinese-domestic and ex-China material.
- Whether U.S. price-floor and equity deals draw countervailing-duty or WTO subsidy scrutiny.
- Lynas's single-hub concentration in Malaysia after the Seadrift stall, and any revived push for U.S. or European separation.
