American rare earth miners are sending most of their output to Japan and South Korea, even as Washington pours more than $1.2 billion into grants and conditional funding to build a domestic magnet supply chain. The largest recipients — MP Materials, Energy Fuels, and Phoenix — are using public money to scale production but shipping the processed oxides abroad for conversion.
The US still makes 1,000 tonnes or less of neodymium iron boron magnets a year, compared with Japan’s 10,000–15,000 tonnes. Energy Fuels’ $1.9 billion deal for German magnet maker Vacuumschmelze shows how companies are solving the onshoring problem by buying foreign capacity rather than building American plants.
The US government has committed $1.28 billion in grants and conditional funding to build a domestic rare earth magnet supply chain. The largest recipients are still sending their output to Asia.
MP Materials, Energy Fuels and Phoenix — the three companies that dominate American rare earth mining and processing — are exporting most of their material to Japan and South Korea. The reason is straightforward: the US lacks the industrial capacity to turn those oxides into magnets. And the companies are finding it faster to buy German and Korean magnet plants than to wait for homegrown factories to emerge from government-funded pilot projects.
In June 2026, Energy Fuels announced a $1.9 billion acquisition of Vacuumschmelze, the German magnet maker. The same month, it sealed $725 million in conditional US funding. The message from the market was unambiguous: the quickest way to claim “capacity” is to buy it. It is harder to build it from scratch in Fort Worth or Mountain Pass.
The policy objective is a fully American rare earth supply chain. The industrial reality is a feedstock pipeline feeding established Asian factories that make the magnets for electric vehicles, smartphones and F-35s.
The magnet gap that money cannot close quickly
Energy Fuels’ chief executive Ross Bhappu confirmed the near-term strategy: the company will send rare earth oxides to Korea “in the near future.” A major South Korean manufacturer had already converted a small batch of the company’s neodymium-praseodymium into magnets in 2025. The new plan is to do much more.
MP Materials, which runs the Mountain Pass mine in California, stopped selling to China’s Shenghe Resources as part of its US government pact. It now ships to Japan and South Korea, plus an unnamed US technology and industrial firm under a deal struck in early 2026. It also has long-term contracts to supply finished magnets to General Motors and Apple — but those magnets will not begin shipping until later this year, at the earliest.
Consultant John Ormerod, of JOC LLC, traces the numbers that explain the export imperative. Japan turns out 10,000 to 15,000 tonnes of neodymium iron boron magnets annually. South Korea produces 2,000 to 3,000 tonnes. The United States manages 1,000 tonnes or less. China, he notes, remains the world’s largest producer, setting the global price floor.
Gina Raimondo, the US Secretary of Commerce, has called dependence on foreign critical mineral supply chains a “national security risk.” Industry analyst James Kennedy warns that without comprehensive downstream investment, US mining “risks becoming a feedstock supplier to Asian magnet makers rather than a full domestic supply chain.” Kathleen Barrón, a senior executive at Constellation Energy, points out that Inflation Reduction Act-linked incentives are reshaping investment but that “build-out of domestic manufacturing capacity lags the rapid growth in demand for critical inputs.”
The production gap that forces American rare earths onto ships bound for East Asia is made visible in a single set of figures.
Washington wrote the cheque. Tokyo and Seoul own the line.
Rare earth prices offer little help. Neodymium prices in mid‑2026 are subdued compared with the 2021‑2022 peaks, reflecting slower EV demand growth and ample magnet capacity in East Asia, according to market trackers. That pressures the margins of new US projects that must still post oxide shipments before their own magnet plants come online.
The regulatory picture is just as tough. US rare earth projects face a tangle of federal and state rules — NEPA environmental reviews, EPA hazardous waste obligations, Bureau of Land Management leasing — while the main funding relies on Defense Production Act Title III and programs under the Infrastructure Investment and Jobs Act and the Inflation Reduction Act. Unlike the EU’s Critical Raw Materials Act or Australia’s more streamlined regime, the US approach showers projects with subsidies but does little to shorten permitting timelines.
The forward view hinges on a few milestones. MP Materials expects to ship finished magnets to General Motors sometime in 2026. If that date slips beyond this year, Asian processing will remain essential and the onshoring narrative will lose credibility. At the same time, regulatory approvals for Energy Fuels’ acquisitions of Australian Strategic Materials and VAC are expected over the next six to twelve months. Clearance would cement a hybrid US‑Asia‑Europe magnet network — but not an independent American one.
Washington wrote the cheques. The magnet lines that turn those dollars into productive capacity are still thousands of miles away, in Japan and South Korea.
Beyond the headline
The Money Trail
The funding architecture reveals why US rare earths are still flowing abroad: Washington is pouring billions into miners and mid‑stream processors, but the fastest route to monetisation is selling feedstock into Japan and South Korea’s existing magnet plants. Acquiring foreign manufacturers lets US firms book near‑term revenues while formally ticking the “capacity” box, even if the critical conversion steps remain anchored in East Asia rather than on US soil.
The Power Behind It
Control over the supply chain today rests less with miners than with those who own magnet know‑how and installed plants. Japan and South Korea command leverage because they can turn oxides into indispensable components for EVs and defense hardware at scale, while China’s dominance sets the global price floor. US agencies can write cheques, but until domestic magnet lines operate at comparable scale, they lack the industrial power to dictate terms.
The Timing
This story is unfolding at the intersection of climate policy deadlines, auto industry model cycles and election‑driven security rhetoric. EV targets and clean‑energy tax credits are ramping now, but magnet projects only started receiving major funds in 2024–2026, creating a multi‑year lag between policy intent and industrial reality. That gap ensures Asian plants remain indispensable through this decade, regardless of how aggressive new US announcements sound.
The decisions the gap now forces
With US government‑backed magnet projects facing several years’ lag between funding and full output, three groups must act now.
- US Policy Maker
Track the Department of Energy’s critical minerals funding announcements to see if timelines for MP Materials’ magnet shipment to GM hold. If the 2026 target slips, prepare for a fresh round of congressional scrutiny and pressure to impose export controls on raw oxides — measures that would anger allies in Seoul and Tokyo before any US substitute exists.
- Institutional Investor
Compare the US Geological Survey’s annual Mineral Commodity Summaries rare earth data with the value of your equity positions in MP Materials, Energy Fuels and Phoenix. Near‑term cash flows still depend on export volumes to Asia, not on American magnet premiums. Any disruption to those export channels — from trade friction or an accelerated domestic-build push — would re‑price these companies quickly.
- Automotive Supply Chain Executive
Dual‑source your neodymium iron boron magnets now. GM and Apple have secured long‑term contracts with MP Materials, but the US magnet plant is not yet producing at scale. Maintain at least one qualified East Asian supplier through 2028 to protect assembly lines from a domestic start‑up that could miss its ramp‑up by a year or more.
Explainer
- NdFeB magnets
- Neodymium iron boron magnets are the strongest permanent magnets available, essential for EV motors, wind turbines and defense guidance systems. They are made from a mix of rare earth oxides that must be processed into alloys and shaped under specific magnetic orientation. The manufacturing step where most value is added — and where China, Japan and South Korea dominate — is not the US mining but the downstream metallurgy and magnet assembly.
- Rare earth oxides
- Rare earth oxides are the initial refined product extracted from mined ore. They contain the separated rare earth elements — neodymium, praseodymium, dysprosium — but are not yet magnets. An oxide shipment leaving the US represents an unfinished input that must cross an ocean to enter a furnace, meaning the highest‑value work stays in Asia.
- Defense Production Act (DPA) Title III
- A Cold War‑era law that lets the US president direct the private sector to produce goods for national defense. Since 2020, Title III has been invoked to fund rare earth separation and magnet projects to reduce reliance on Chinese supply. It provides grants and purchase commitments but does not override state‑level environmental permitting, which remains a major bottleneck for new plants.
