US rare earth supply gap threatens Trump's 2027 China mineral ban

The US needs 48,000 metric tons of rare earth magnets a year but produces just 300 — and the January 2027 deadline to stop buying from China is five months away.

The Trump administration's push to end US purchases of Chinese critical minerals by January is colliding with a stark reality: American miners and processors can meet less than 1% of domestic demand for rare earth magnets.

"It's going to take many more years to get the needed infrastructure in the ground to compete," Chris Berry, a minerals industry analyst and consultant, said.

US demand for the most common type of rare earth magnet was roughly 48,000 metric tons in 2025, while domestic sources supplied just 300 metric tons, according to data from Arthur D. Little consultancy. US firms are on track to have capacity to produce 5,000 metric tons by year-end. The US has not produced tungsten since 2015 or tantalum since 1959.

The International Energy Agency warned this month that $6.5 trillion of global manufacturing is at risk if Beijing imposes export restrictions on rare earths. China controls more than 80% of the minerals refining sector today.

$12 Billion in Pentagon Loans Flow to Critical Minerals Startups

The Defense Department has poured tens of billions of dollars into nearly 150 minerals companies. MP Materials, backed by the Pentagon, built a magnet facility in Texas and expects to supply General Motors by year-end, CEO Jim Litinsky said. A separate Pentagon facility is slated for 2028.

Ucore Rare Metals developed a processing technology called RapidSX but pushed back production to 2027 at the earliest after what CEO Pat Ryan described as changing Pentagon demands. "Can the entire supply chain be propped up by 2027? Boy, I tell you, that's a battle," Ryan said.

Energy Fuels received a $725 million Pentagon loan last month and plans to process 6,000 metric tons of rare earths annually by 2029. Phoenix Tailings secured a $500 million loan to build a processing facility. Nova Minerals won a $43.4 million Defense Production Act award for an antimony mine in Alaska, with first production targeted for 2027.

Project Vault Stockpiling Exposes $6.5 Trillion China Dependency

The Trump administration in February launched Project Vault, a $12 billion effort to stockpile critical minerals. Officials acknowledged in April they would need to buy from "anywhere in the world," including China. Defense contractor Lockheed Martin has submitted a list of minerals it wants stockpiled, CEO Jim Taiclet said.

The stockpiling push frustrates US miners who say defense contractors must place orders with them. "Defense contractors have just assumed they can keep buying Chinese products," said Nick Myers, CEO of Phoenix Tailings. "The defense industry is never going to stop if you keep giving waivers."

Trump railed against waivers in a May 10 post on Truth Social, saying "ALL FEDERAL AGENCIES MUST BUY AMERICAN — NO EXCUSES!" An executive order signed July 20 tightened waiver rules, requiring contractors to show "exhaustive effort" to avoid Chinese material.

Partnerships with South Korea, Japan and other allies may offer a bridge until US suppliers ramp up, said Samantha Carl-Yoder of law firm Brownstein Hyatt Farber Schreck.
