Trump Orders Defense Contractors to End Reliance on Suppliers From Adversary Nations

President Donald Trump signed an executive order Monday (July 20) that requires defense contractors to map their supply chains and encourages them to shift their sourcing of critical materials to suppliers in the United States or partner nations.

The order aims to secure the critical materials and components needed to manufacture cutting-edge equipment used on modern battlefields, the White House said in a Monday fact sheet.

“Despite the longstanding prohibition on the use of sensitive materials sources from geopolitical adversaries, defense contractors have historically under-prioritized domestic production and resilience,” Trump said in the order. “My Administration will act to ensure that the statutory requirements of 10 U.S.C. 4872 are strictly observed and result in resilient domestic and allied supply chains.”

The executive order refers to a law [10 USC 4872] that prohibits the acquisition of sensitive materials from non-aligned foreign nations.

The order limits the circumstances in which the Secretary of Defense should issue waivers under this law, directs the Defense Department to initiate regulatory action requiring more comprehensive supply chain mapping for critical supply chains, and encourages defense contractors to begin qualifying new domestic sources of critical minerals, materials and components, according to the fact sheet.

White House Press Secretary Karoline Leavitt said in a Monday post on X: “President Trump signs order to make U.S. supply chains more secure, less reliant on foreign nations.”

Bloomberg reported Monday that Peter Navarro, a senior trade adviser to the president, told reporters that the Defense Department needs to know if a critical system depends on a foreign-controlled supplier and that these dependencies are sometimes hidden.

“America’s vulnerabilities are buried in the lower tiers: The subcontractors and vendors supplying specialty metals, electronics, chemicals, software and raw materials that Washington is not watching,” Navarro said, per the report.

The report said that last year, China retaliated for tariffs imposed on it by the United States by limiting exports of some rare earth materials and permanent magnets.

Reuters reported Monday that materials can pass through dozens of suppliers before reaching the company that build the final product, and that the executive order aims to identify and eliminate any vulnerabilities.
