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.
Source report
President Donald Trump on Monday signed an executive order making it harder for U.S. defense contractors to obtain waivers allowing them to buy critical minerals and other materials from China and other prohibited foreign suppliers. The move represents the administration’s latest effort to reduce reliance on overseas supply chains for weapons production.
Stricter Waiver Requirements
Under the new rules, defense contractors will have to do much more than simply show that a Chinese supplier is the easiest or cheapest option. Companies seeking a waiver must:
- Prove they searched for alternatives
- Explain where their materials come from
- Lay out a plan to move away from prohibited suppliers
Contractors will face the loss of contracts if they fail to demonstrate sufficient efforts to source domestically.
“No more: ‘we tried nothing and we’re out of options’,” White House adviser Peter Navarro told reporters during a briefing before the executive order was released.
Context and Industry Impact
The order comes as the Pentagon pushes defense contractors like Lockheed Martin and Boeing to rapidly expand weapons production while facing persistent vulnerabilities in the supply chains that feed the U.S. military.
Many critical minerals and processed materials used in missiles, aircraft and other advanced systems still rely on Chinese suppliers, leaving companies caught between demands to move away from Beijing and the need to keep weapons flowing to U.S. forces and allies.
Supply Chain Mapping Requirements
Beyond tightening waiver requirements, the executive order directs the Pentagon to develop rules requiring contractors to map critical defense supply chains from raw materials through finished military products. Companies will be required to:
- Identify the origins of minerals, components, software and other inputs used in designated weapons systems
- Extend government visibility beyond prime contractors to lower-tier suppliers
“This is not paperwork. It is battlefield preparation,” Navarro said, arguing the Pentagon needs to know whether missile systems or other military platforms depend on foreign-controlled suppliers before a conflict begins.
Supplier Risk Assessment
The order also requires contractors to:
- Assess suppliers for foreign ownership, financial vulnerability and manufacturing risks
- Replace suppliers deemed unreliable
