President Donald J. Trump signed an executive order on Monday imposing strict new limits on defense contractors that rely on foreign-sourced critical materials, setting a hard deadline to phase out key administrative waivers.
The executive order, titled “Securing America’s Defense Supply Chains and Ensuring Domestic Acquisition of Critical Materials,” directs the Department of War to stop issuing standard waivers for foreign components starting January 1, 2027.
Under 10 U.S.C. 4872, military contractors are barred from using sensitive materials sourced from geopolitical adversaries, though exemptions have historically been granted when domestic alternatives were unavailable.
Under the new directive, contractors seeking waivers after the 2027 deadline must submit formal mitigation plans. These plans must identify the source of non-compliant materials, document exhaustive efforts to find domestic or allied alternatives, detail steps to eliminate foreign sourcing, and set a firm timeline for compliance.
“The United States military is the most effective and powerful fighting force on the planet,” the order states. “To continue this dominance in an era of renewed great power competition, the United States must secure its supply chains against physical, cyber, and economic subversion.”
The order explicitly clarifies that a contractor’s failure to qualify a domestic supplier does not automatically count as “non-availability” unless the firm actively funds and pursues domestic sourcing options.
The directive also introduces strict mandatory mapping requirements. Within 180 days, the Secretary of War must establish guidelines forcing defense contractors across all supply chain tiers to trace materials back to their raw origin. Contractors must submit an “indentured Bill of Materials” detailing every component, software item, and raw material source.
Additionally, contractors will be required to vet their suppliers for financial instability, foreign ownership, control, or influence, and manufacturing vulnerabilities. Identified supply chain risks must be reported to the Department of War within 15 days, followed by a corrective action plan within 45 days.
Contractors found submitting fraudulent mitigation plans or failing to follow through on approved timelines face administrative remedies, contract terminations, or potential referral to the Department of Justice for criminal investigation.
The order exempts certain international ventures, including critical mineral projects financed by the Export-Import Bank of the United States—such as the U.S. Strategic Critical Minerals Reserve, known as “Project Vault”—as well as initiatives funded by the International Development Finance Corporation, Department of State, Department of Commerce, or Department of Energy.
The Secretary of War is required to submit progress reports to the Assistant to the President for National Security Affairs every six months through January 1, 2028.
