Trump may permit Chinese minerals as US industry faces 2027 deadline

The US has a deadline. On January 1, 2027, American defense contractors and manufacturers must stop buying critical minerals from China, Russia, Iran, and North Korea. Full stop, no exceptions, that’s the law.

There’s just one problem: the US doesn’t have nearly enough of its own supply to replace what it currently buys from those countries.

The math doesn’t work yet

China controls over 80% of global rare earth refining capacity. That’s not a temporary quirk of the market. It’s the result of decades of deliberate industrial policy, cheap labor, and an environmental permitting culture that made processing rare earths economically viable in ways that Western regulators have historically resisted.

The minerals in question aren’t obscure. Rare earths, tungsten, molybdenum, and tantalum show up in fighter jets, missile guidance systems, electric vehicle motors, and semiconductor manufacturing. In English: cutting off Chinese supply without a domestic alternative isn’t a bold strategic move. It’s a production stoppage.

Pentagon-backed domestic mining projects are in development, but most aren’t expected to reach meaningful output until somewhere between 2027 and 2030. The deadline and the solution are arriving at roughly the same time, which leaves a window where compliance is technically required but physically impossible.

One senior mining executive said the 2027 timeline is “simply not achievable” without significant changes to permitting processes.

China already paused exports once, and the US blinked

Earlier in 2025, China restricted rare earth exports to the US as part of broader trade tensions. In June 2025, the Trump administration reached an agreement with Beijing that allowed those shipments to resume.

That episode illustrated something important: for all the tariffs, subsidies, and strategic rhetoric about decoupling from Chinese supply chains, the US industrial base still depends on Chinese refining in ways that create real negotiating constraints. When China turned off the tap, the response wasn’t a domestic production surge. It was a deal.

What exceptions or delays would mean for markets

If the Trump administration grants waivers or pushes the deadline, the immediate effect on supply chains would be stabilizing. Defense contractors wouldn’t face production halts. Manufacturers dependent on rare earth inputs could continue operating without emergency procurement scrambles.

Any formal exception granted to Chinese mineral imports would effectively signal that the 2027 mandate has softer teeth than the legislation implies. That signal would ripple through investment decisions in domestic mining and processing, potentially slowing the capital flows that alternative supply chains need to develop.

Mineral prices themselves could see volatility as the deadline approaches. Any indication that exceptions will be granted could compress the premium that domestic and allied-nation suppliers have been able to charge. Conversely, any hawkish signal suggesting strict enforcement would push prices higher and accelerate investment into alternative sources in Canada, Australia, and allied processing facilities.

If the Trump administration moves to streamline environmental review and approval processes for critical mineral projects, that would be the most durable signal that the 2027 mandate is meant to be enforced rather than delayed. Without that, the administration is essentially choosing between Chinese imports and production disruptions, and based on June 2025, it has already demonstrated which of those two options it finds more tolerable.
