Trump signs executive order tightening defense supply chain waiver rules on 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 searched for alternatives, explain material origins, and submit plans to move away from prohibited suppliers, with contract loss as a penalty. It also directs the Pentagon to mandate supply chain mapping from raw materials to finished military products, requiring contractors to identify origins of minerals, components, and software, and assess suppliers for foreign ownership and risks. White House adviser Peter Navarro framed the move as 'battlefield preparation' to reduce reliance on overseas supply chains amid Pentagon efforts to boost weapons production with Lockheed Martin and Boeing.
