US-funded rare earths to Asian markets: supply-chain takeaways for mine planners
Reviewed by Joe Ashwell

30 Second Briefing
US-backed rare earths producers MP Materials, Energy Fuels and Phoenix Tailings, which together have secured billions of dollars in federal support including a $725 million package for Energy Fuels and $500 million for Phoenix Tailings, are selling most NdPr oxides and metals to Japan and South Korea via channels such as Sumitomo Corp. MP Materials has halted concentrate sales to China’s Shenghe Resources and plans to start supplying finished magnets to General Motors this year, while Energy Fuels is acquiring Australian Strategic Materials and German magnet maker Vacuumschmelze in a $1.9 billion deal to onshore more magnet capacity. The pattern shows upstream US mining and processing capacity is outpacing domestic NdFeB magnet manufacturing, leaving producers reliant on Asian demand until US downstream plants are built and qualified for defence and EV supply chains.
Technical Brief
- MP Materials channels most NdPr oxide and metal via Sumitomo Corp into Japan’s magnet supply chain.
- Mountain Pass output is no longer sold as concentrate to China’s Shenghe Resources under US government terms.
- Energy Fuels’ near‑term plan is export of rare earth oxides to South Korea from its US facilities.
- Acquisition of Australian Strategic Materials gives Energy Fuels direct access to an operating South Korean rare earth metals plant.
- Phoenix Tailings reports its paying customers are “primarily in Korea and Japan”, driven by post‑restriction demand growth.
- MP Materials benefits from a federal pricing agreement guaranteeing minimum prices for specified rare earth products during ramp‑up.
- China currently accounts for ~90% of global NdFeB magnet output; Japan is the largest producer outside China.
- For other critical mineral projects, the case illustrates upstream mining/processing can scale faster than downstream alloying and magnet fabrication capacity.
Our Take
MP Materials and its Mountain Pass mine already feature in our coverage via China’s 2026 export controls on the company and USA Rare Earth, so US-backed output flowing to Asian NdFeB magnet makers sits awkwardly alongside tightening Chinese technology restrictions on the same operators.
The Energy Fuels–Vacuumschmelze US$1.9 billion deal effectively marries a US critical minerals player with a German magnet specialist at a time when China still accounts for about 90% of NdFeB magnet output, signalling a push to build non-Chinese magnet capacity that can serve both US and allied Asian OEMs.
