Trump signs executive order tightening defense supply chain waiver rules

Published Jul 20, 08:30 PM UTC

President Donald Trump signed an executive order on July 20, 2026, making it harder for U.S. defense contractors to obtain waivers to buy critical minerals and materials from China and other prohibited foreign suppliers. The order requires companies to prove they have searched for alternatives, explain material origins, and submit plans to shift away from prohibited sources. Contractors face contract loss if they fail to demonstrate sufficient domestic sourcing. The Pentagon is also directed to mandate supply chain mapping from raw materials to finished weapons, including lower-tier suppliers. White House adviser Peter Navarro framed the move as 'battlefield preparation' to reduce reliance on foreign-controlled suppliers. The order targets persistent vulnerabilities in defense supply chains, especially for missiles and aircraft, amid pressure on firms like Lockheed Martin and Boeing to boost production.
