For defense contractors, sourcing geography is a compliance decision before it is a cost decision. DFARS, ITAR, and Buy American constraints narrow the field in ways commercial manufacturers never face.
Compliance as a Gate
Specialty-metals and Buy American clauses can disqualify offshore sources outright for covered items. ITAR-controlled technical data adds another layer. Compliance is the first filter, not the last.
The Cost of Traceability
Offshore sourcing multiplies the cost of country-of-origin verification and counterfeit-parts control. Nearshore and domestic sources simplify traceability — a real, if hidden, cost advantage.
Making the Call
For covered and critical items, default to compliant domestic or nearshore sources. Reserve offshore for commercial, non-covered commodities where traceability burden is low.
Key Takeaways
- Compliance gates the sourcing decision for covered items.
- Offshore multiplies traceability and counterfeit-control cost.
- Default covered/critical items to compliant domestic or nearshore sources.
