185 Days. 90% Chinese Processing. $931/kg Dysprosium Outside China.

On March 31, 2026 — three days before Trump flew home from Beijing — Premier Li Qiang signed State Council Order No. 834 and issued it with no transition period, no grace window, and no advance notice: China's first unified regulation on industrial and supply chain security, effective the moment it hit the official gazette. Thirteen days later, on April 13, Beijing followed with a companion instrument — the Regulations on Countering Improper Extraterritorial Jurisdiction — building a legal framework that could authorize MOFCOM to sanction any multinational, anywhere in the world, that makes commercial decisions Beijing decides are harmful to Chinese supply chain stability. Both documents took effect immediately. Neither received meaningful coverage in the Western financial press.

This is the architecture being assembled behind the truce. On November 7, 2025, at the Busan APEC summit, Xi and Trump agreed to a one-year suspension of China's most expansive rare earth export controls — the October 2025 measures that had added five new elements to the restricted list, banned transfers of processing equipment, and extended Chinese licensing jurisdiction to products made anywhere in the world containing as little as 0.1% by value of Chinese-origin rare earth material. That suspension expires on November 10, 2026 — 185 days from today. The controls are suspended, not repealed. The legal framework never went away. What Order No. 834 did was consolidate it, sharpen it, and give the State Council the authority to reinstate it — and extend it — faster than any previous instrument allowed.

Meanwhile, China's Ministry of Industry and Information Technology published a draft enforcement framework on April 29 adding criminal and administrative penalties for illegal rare earth mining, smelting, and separation — tightening production-stage control without touching the export regime at all. Beijing can squeeze the flow from the mine gate forward, independently of whatever the export licensing system says. The Busan suspension covers ports. It doesn't cover the pit.

The April 2025 controls on the original seven heavy rare earth elements — dysprosium, terbium, lutetium, samarium, gadolinium, scandium, and yttrium — were never suspended. They remain active. Under those controls, China requires case-by-case licensing for any rare earth shipment touching defense-relevant end users. Sixteen US defense contractors were blacklisted outright. The Busan agreement did not reinstate their access. Lockheed Martin, RTX, Northrop Grumman, and Boeing are still operating under a supply regime where China holds direct veto power over the specific rare earths that make jet engines, missile fins, and radar actuators function at the temperatures they encounter in combat.

Dysprosium is trading at $931/kg outside China — up more than 100% since March. Inside China the same material clears at roughly $240/kg. Terbium ex-China: above $4,000/kg. The spread is not a market anomaly. It is the price of a chokepoint that is still running.

Every F-35 rolling off the Lockheed Martin line in Fort Worth contains approximately 427 kilograms of rare earth materials — spread across engines, radar, power systems, and electronic warfare packages. The materials inside that airframe run from neodymium and praseodymium in the primary drive magnets to dysprosium and terbium in the high-temperature motor components that have to function at the edge of the thermal envelope where cheaper magnets demagnetize and fail. In 2022, the total US government stockpile of dysprosium metal was 203 kilograms. Annual defense consumption runs near 400 tonnes. The math is not difficult. China controls roughly 90% of global rare earth processing and more than 90% of high-performance magnet manufacturing

The clock has two faces. Face one: November 10, 2026 — the Busan suspension expires. The full October 2025 control package, which includes the extraterritorial FDPR provision, reinstates automatically unless both governments renegotiate before that date. Face two: January 1, 2027 — the DFARS rule under 10 U.S.C. §4872 takes full effect, prohibiting any Chinese rare earth content in magnets delivered to the Pentagon. Defense contractors must complete their supply chain transition before the first Pentagon delivery of 2027. The two deadlines are 52 days apart. In the space between them, every major US defense prime — Lockheed, RTX, Northrop, General Dynamics — must have secured sufficient non-Chinese supply of dysprosium and terbium alloy to meet production schedules. As of this writing, there is no commercial-scale heavy rare earth metallization facility outside China anywhere in the Western hemisphere. Lynas's Texas refinery, backed by a $120 million DoD contract, is targeting operational status in 2026. REalloys in Euclid, Ohio has an Export-Import Bank letter of intent for $200 million and is projecting Phase 1 output of 30 tonnes of dysprosium oxide per year — against a defense sector that consumes 400 tonnes annually.

The production is 7.5% of demand. The rest has no backup.

NdPr oxide — the light rare earth pair used in EV traction motors, wind turbine generators, and the AI data center power infrastructure currently absorbing hundreds of billions in capital expenditure — is up 45% year-to-date, per Morningstar data through April 30. Bloomberg Intelligence projects a 36% global shortfall of NdPr by 2030, even assuming $10 billion in public funding flows to alternative supply chains in 2026 as planned. New mines take ten to fifteen years to reach production. The Busan suspension bought manufacturers one year to build a backup that takes a decade to construct. The gap between what was promised and what can be delivered in 185 days is the operational exposure.

China is running two operations at once. The first is diplomatic — maintaining the Busan suspension and keeping Western manufacturers dependent on Chinese access while the clock runs. The second is structural — Order No. 834, the April 13 extraterritorial jurisdiction regulations, and the April 29 MIIT enforcement framework are all pieces of a permanent legal architecture that exists regardless of what happens on November 10. When the truce ends, Beijing will not need to make new policy. The policy is already written.

The rare earth story is not about mining stocks. It is about the cost floor of everything built from a motor. EVs, wind turbines, robotics, HVAC compressors, the MRI machine at the hospital, the traction motor in the train, the power conversion unit inside the AI data center running your brokerage's back office — all of them run on NdFeB permanent magnets, and all of those magnets run on rare earth inputs that are 90% controlled by one country and priced at a spread that is already punishing every manufacturer outside it. NdPr is up 45% year-to-date. Dysprosium has more than doubled since March. Those prices are inputs to products. Inputs to products are costs. Costs become prices. The transmission lag is six to eighteen months.

The defense angle is the sharper edge because it has a hard deadline and no good answer. The Pentagon is spending roughly $1.7 trillion on the F-35 program over its lifetime. The magnets that go into each airframe currently contain material that will be illegal to use in any future delivery after January 1, 2027. The domestic supply chain to replace that material does not yet exist at the required scale. Defense contractors do not publicize this in their quarterly calls. They describe it in 10-K risk factors under the heading "critical materials and components," where it is easy to miss and difficult to price.

On November 10, 2026, the Busan truce expires — and with it, the one-year suspension of China's extraterritorial rare earth controls that would allow MOFCOM to require an export license for any product made anywhere in the world containing as little as 0.1% Chinese-origin rare earth material. If those controls reinstate on schedule, Japanese automakers assembling EVs in Ohio, German turbine manufacturers shipping to US wind farms, and Korean chipmakers using Chinese-processed rare earth inputs in deposition equipment all face Chinese export licensing requirements before their products can leave their home factories. The $10 billion in 2026 public funding for alternative supply chains was announced in budget line items in four separate countries. It was celebrated in four separate press releases. It covers roughly one-third of the capital cost of the infrastructure needed, on a timeline that runs past 2030 — four years after the deadline.
