Trump signs executive order tightening waiver rules for defense supply chain purchases from China

President Donald Trump signed an executive order on July 20, 2026, making it harder for U.S. defense contractors to obtain waivers allowing them 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 move away from prohibited suppliers, with contract loss as a penalty for non-compliance. The Pentagon is also directed to mandate contractors map critical defense supply chains from raw materials to finished products, identify origins of inputs, and assess suppliers for foreign ownership and financial risks. White House adviser Peter Navarro framed the measures as 'battlefield preparation' to reduce reliance on foreign-controlled suppliers before potential conflicts. The order addresses persistent vulnerabilities in supply chains for missiles, aircraft, and other advanced systems, amid Pentagon pressure on contractors like Lockheed Martin and Boeing to expand weapons production.
