Trump's Executive Order Tightens Defense Rare Earth Rules, but US Magnet Supply Gap Won't Close by 2027
On July 20, President Donald Trump signed an executive order requiring the Department of Defense to phase out most waivers by January 1, 2027, that have allowed defense contractors to procure samarium cobalt (SmCo) and neodymium iron boron (NdFeB) magnets, tantalum metal and alloys, tungsten metal powder and heavy alloys, and molybdenum from "non-allied foreign countries"—namely China, Russia, Iran, and North Korea. From 2027 onward, contractors or subcontractors seeking a waiver must submit a DoD-approved mitigation plan, prove the precise origin of non-compliant materials, demonstrate extensive efforts to source compliant alternatives, and lay out a timeline for removing prohibited materials from their supply chains. In parallel, the order directs the DoD to issue policy guidance within 180 days, pushing contractors to map critical supply chains "from raw materials to end-use products" and to begin qualifying domestic sources of critical minerals, materials, and components.
The Real Weight of the Order: Closing Loopholes, Not Breaking New Ground
To assess the order's true significance, it must be read against Section 4872 of Title 10 of the US Code, enacted in 2018, which already prohibited the DoD from procuring the above sensitive materials from "adversary countries," with SmCo and NdFeB magnets being the core rare earth items at stake. The problem was that, for years, America's domestic rare earth permanent magnet industry remained too thin to meet defense demand, so the DoD kept issuing case-by-case waivers to keep Chinese imports flowing legally.
The actual teeth of Trump's order lie not in the procurement ban itself—the law already mandated that—but in shifting waivers from "default issuance" to "item-by-item strict review," with "inability to build domestic supply" explicitly ruled out as a valid excuse. White House trade advisor Peter Navarro put it bluntly: contractors can no longer claim they had no choice without having tried anything. Symbolically, this marks the Trump administration's push to move "de-China-ification of the defense supply chain" from slogan to enforceable institution.
Why the US Is Now "Following China's Playbook"
The most telling provision is the 180-day mandate to build a full-chain traceability system—a clear benchmark against China.
Since the Rare Earth Regulations took effect on October 1, 2024, China has required mining and smelting-separation enterprises to maintain flow-recording systems. In February 2025, the Ministry of Industry and Information Technology (MIIT) circulated the Interim Measures for Rare Earth Product Information Traceability Management for public comment, establishing a rare earth traceability system jointly operated by MIIT, the Ministry of Natural Resources, the Ministry of Commerce, the General Administration of Customs, and the State Taxation Administration, covering the entire chain from production to circulation to use. Enterprises must upload product flow data to the government traceability platform monthly by the 10th of each month. Layered on top of this are the export controls on medium-and-heavy rare earth items implemented since April 2025, the "de minimis traceability" rule requiring licenses for re-exported products containing Chinese rare earth content above certain thresholds, and the whistleblower reward mechanisms rolled out in July 2026. Together, these form a closed-loop regulatory system of "quota—traceability—export review—anti-smuggling.
The US requirement to map supply chains "from raw materials to final military products" is, at its core, an acknowledgment that any procurement ban is paper-thin without visibility into downstream flows. China has wielded its traceability system to make its rare earth leverage precise; the US is now forced to learn the same lesson.
The Reality for US Defense: The Magnet Gap Cannot Be Closed by 2027
The market consensus that this ban carries far greater symbolic than practical weight holds up—and the root cause is the awkward state of US domestic rare earth magnet capacity.
USA Rare Earth's commercial sintering NdFeB production line at Stillwater, Oklahoma, only began commissioning in March 2026. The company expects to reach a run-rate of 600 metric tons per annum (mtpa) by the end of Q4 2026, scaling to a combined 1,200 mtpa across two lines in Q1 2027. Even adding the planned 6,400 mtpa greenfield base at the Bailey Industrial Park in South Carolina, plus supporting projects such as MP Materials' NdPr conversion in Texas and Lynas' heavy rare earth separation plant in Texas, the overall progress remains in the "0-to-1" ramp-up stage.
For context, mature magnet makers in Japan—Proterial, Shin-Etsu—each operate single-site capacities in the 2,000–3,000 mtpa range with deep technical moats, while China dominates global rare earth magnet supply and refining capacity. Annual US defense and high-end manufacturing demand for NdFeB magnets far exceeds the sum of all domestically planned capacity, meaning that when the waiver gate closes in 2027, domestic supply will clearly be insufficient to backfill.
The heavy rare earth segment is even more precarious. MP Materials' NdPr oxide has yet to be effectively converted into metal and magnets in the short term. Lynas' heavy rare earth separation plant in Texas remains sluggish. Energy Fuels has spent heavily to acquire European magnet veteran VAC to expand heavy-rare-earth-containing magnet capacity, but short-term supply of dysprosium- and terbium-containing high-performance magnets remains inadequate, with feedstock still heavily dependent on Chinese or allied transshipment.
Expected Impact on China's Rare Earth Exports
For China, this executive order adds further uncertainty to the year-end 2026 extension of export controls and the issuance of general licenses. Considering the market adjustments following the April 2025 tightened controls and the gradual refinement of relevant legal and policy frameworks, the probability of a repeat of the aggressive April 2025 restrictions is relatively low. However, total NdFeB export volumes in 2026 are likely to take a hit.
In the medium-to-long term, US "de-China-ification" will advance along two tracks: one is the "mine-to-magnet" vertical integration model exemplified by USA Rare Earth, targeting 10,000 mtpa of NdFeB capacity; the other is capacity expansion at high-end magnet bases in Japan and Europe (VAC, Neo, etc.). Both tracks point to the same reality—the US is spending 5–10 years plugging the magnet gap, but with rigid defense supply chain demand in place, the curve of declining dependence on China during the transition period will be far flatter than the political rhetoric suggests.
One easily overlooked detail: the executive order explicitly excludes the US Strategic Critical Minerals Reserve (the so-called "Project Vault") and critical minerals produced by projects financially supported by EXIM or DFC from its scope. This effectively leaves a "back door" for the US—strategic stockpiling and federally funded projects can still be handled flexibly. This also confirms from the side that the order's true intent leans more toward "establishing rules and tightening accountability" than "cutting off supply tomorrow."
Final Assessment
Placed in the broader context of the US-China rare earth contest, this executive order is neither the decisive "decoupling" strike nor a merely symbolic political gesture. It is an act of institutional alignment—the US has realized that to hold equivalent leverage in the rare earth game, it must first build supply chain visibility on par with China's. But institutions can be signed overnight; capacity has to be ramped up ton by ton.
