US to Restrict Critical Materials from China in Defense Supply Chains

The United States is implementing stricter regulations aimed at reducing reliance on China and other adversarial nations for critical materials essential to its defense supply chains. An order signed by President Donald Trump on Monday, July 20, 2026, will make it more difficult for defense contractors to obtain waivers for sensitive materials.

Beginning in January 2027, companies seeking to use materials from "non-allied foreign nations", generally defined as China, North Korea, Russia, and Iran, will need to provide extensive documentation. This includes demonstrating exhaustive efforts to source compliant materials or proving that no such alternatives exist. China, a major global producer of rare earths vital for advanced technologies, is a primary focus of these restrictions.

America cannot dominate the modern battlefield if the Department of War does not know where its critical materials, components and software come from.

White House trade advisor Peter Navarro explained that contractors must also detail their plans for removing "non-compliant" sensitive materials from their defense supply chains and establish a timeline for these actions. Currently, waivers allow the procurement of certain materials, like Chinese rare earth magnets, for defense purposes.

Additionally, the order directs the defense secretary to require contractors and subcontractors to map out their critical supply chains that have national security implications. Guidance for these mapping requirements is expected within six months. David Copley, White House senior director of global supply chains, stated that understanding the origin of critical materials is crucial for maintaining American military dominance, characterizing the measure as "battlefield preparation."

This is not paperwork. It is battlefield preparation.
