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

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 searched for alternatives, explain material origins, and submit plans to move away from prohibited suppliers. Contractors face contract loss if they fail to demonstrate sufficient domestic sourcing. The order also directs the Pentagon to require contractors to map critical defense supply chains from raw materials to finished products, identify origins of inputs, and assess suppliers for foreign ownership and financial vulnerability. White House adviser Peter Navarro framed the measures as 'battlefield preparation' to reduce reliance on foreign-controlled suppliers before potential conflicts.
