China is still restricting the rare earth elements that the U.S. needs to produce its own permanent magnets and other products even after President Donald Trump reached a deal with his Chinese counterpart in October to lift restrictions on the supplies, according to market participants.

More than a dozen consumers, producers, government officials and trade experts said that while China has boosted deliveries of finished products — primarily permanent magnets — the U.S. industry remains unable to acquire the inputs needed to make those items on its own, a key priority for the administration. The people asked not to be identified discussing matters that aren’t public.

The reduced trade highlights continuing tensions in the U.S.-China relationship in the months since Trump and Xi Jinping hammered out a truce in South Korea on Oct. 30, with the U.S. cutting tariffs and China pledging to restore rare earth supplies. At the time, Trump said the deal amounted to the “de facto removal” of a range of limits China had imposed.

By restricting deliveries of raw materials, China is hamstringing U.S. efforts to build its own industry to process rare earths into magnets used in everything from consumer goods to missile guidance systems. The Trump administration has made developing domestic production capacity for permanent magnets and other rare earth products a key priority after China spent years building a global monopoly.

The White House didn’t respond to a request for comment for this article. Administration officials have said in recent weeks that China is complying with the terms of the deal on rare earth supplies.

China’s Commerce Ministry also didn’t respond to a request for comment. Beijing has said it’s already approved some applications for rare earth exports. But it continues to restrict supplies that could go to military contractors.

Official Chinese data released Dec. 20 showed magnet supplies to the U.S. dropped 11% in November from the month before, but remain above the lows seen when Beijing restricted them in April. Overall, China’s exports of rare earth elements and products — including magnets — were up 13% in November from the month before, according to Bloomberg calculations using official customs data.

Industry officials and market participants said the reality is different for U.S. players.

“People aren’t getting materials out of China, you’re not getting dysprosium metal or oxide if you’re a U.S. entity,” Scott Dunn, the chief executive of Noveon Magnetics Inc, said in an interview, citing his contacts with others in the industry. Noveon is one of just a few U.S. makers of permanent magnets. The company doesn’t buy rare earth inputs from China, but Dunn said some of his customers do.

“Outside of China, the world can produce 50,000 tons of magnets, but there isn’t even close to the equivalent in rare earth minerals to support those tons outside of China,” Dunn said. “China restricts materials far beyond what it restricts in magnets to keep that dynamic in place.”

To be sure, Beijing’s easing of restrictions on products like magnets made from rare earths has, for the moment, removed the risk that consuming industries like autos and technology might have to shut down production, according to Gracelin Baskaran, director of the critical minerals security program at the Center for Strategic and International Studies in Washington.

“Given we import further down the supply chain, companies don’t feel that interruption nearly as much,” she said. “Because we import more magnets, the impact is much softer.”

China’s overall exports of the raw materials have risen since last year, but the U.S. hasn’t received a similar uptick, according to government data. The stasis for U.S. firms continues even as the European Union said Dec. 15 that China started granting licenses with lengthier terms to allow European companies to obtain rare earths.

The U.S. and China still haven’t reached an agreement on key details of how Beijing will free up sales of rare earths, according to a person familiar with the negotiations. Bloomberg News reported last month that the two sides had given their teams until the end of November to agree on terms for so-called “general licenses” for exports. This has left market participants worried that the truce could collapse.

“We reached various temporary agreements in London, in Geneva, in South Korea and they were reneged,” Baskaran said. “So no agreement so far has proved to be final, and that gives industry a level of skittishness that’s justified.”

The upcoming expiration of six-month temporary export licenses China approved in the early summer to ease market congestion as the two nations negotiated also means American companies will be applying for renewals around the same time, likely creating a logjam of applications. The worry among buyers is that China, as they did in May and June, will slow-walk approvals — a move seen by industry players as a type of export control.

“In discussions with Chinese counsel, the recommendation is to proceed with license applications before the pause expires,” said Mark Ludwikowski, the chair of Clark Hill’s international trade practice. “They could pull the plug on this at any point if this goes south.”
