DFARS compliance fails in the supply chain, not the prime. Most findings trace to a subtier supplier whose country-of-origin, cybersecurity, or counterfeit-parts controls were never verified. This guide maps the core clauses to controls you can actually implement.
The Clauses That Matter Most
DFARS 252.225-7012 (preference for domestic specialty metals), 252.225-7014 (Buy American), 252.246-7007 (contractor counterfeit electronic part detection), and 252.204-7012 (safeguarding covered defense information) form the backbone. Each pushes obligations down to your suppliers.
Country-of-Origin Verification
Specialty metals and Buy American compliance require documented country-of-origin for the actual material, not just the supplier's location. Build a supply chain map that traces origin to the mill or foundry, and require certifications as a condition of PO acceptance.
Counterfeit Parts Prevention
A compliant program requires approved-supplier controls, purchase from OCMs/authorized distributors, incoming test and inspection, and traceability. Gray-market electronics are the highest-risk category — enforce authorized-source purchasing contractually.
CMMC 2.0 Flow-Down
CMMC obligations flow to subcontractors that handle CUI. You must assess which suppliers touch covered information and verify their maturity level. Treat cybersecurity as a supplier-qualification criterion, not an afterthought.
Key Takeaways
- Most DFARS findings originate at subtier suppliers, not the prime.
- Trace country-of-origin to the mill/foundry, not the supplier address.
- Enforce authorized-source purchasing to prevent counterfeit electronics.
- Treat CMMC maturity as a supplier-qualification requirement.
