The short answer
ITAR is not just a label for defense work. It governs defense articles, related technical data, and defense services. That means your RFQ handling process matters before machining starts.
What ITAR changes in sourcing
If the drawing, model, or part falls under ITAR control, you need to know who can access the data, where the work is performed, and whether any foreign-person access is involved. This is not a small commercial footnote. It changes supplier selection and data flow.
The mistake is treating ITAR like a badge you mention after files are already shared.
Supplier questions that matter
Ask whether the supplier handles ITAR-controlled work, how access is restricted, whether subcontracting is controlled, and whether data is stored and transmitted inside compliant processes. Also confirm domestic manufacturing expectations if that is part of your control strategy.
Do not assume a supplier is suitable because it says 'defense capable' on a website.
RFQ handling discipline
Mark controlled data clearly. Limit distribution. Use the right portal or channel. Keep revision control tight. And do not mix ITAR-controlled and uncontrolled package handling out of convenience.
Control failures often happen in admin workflows, not on the machine.
Commercial impact
ITAR control can reduce the supplier pool and increase cost or lead time. That is normal. The right benchmark is compliant execution, not commodity pricing.
Cheap and careless is not a sourcing strategy.

The right move is usually to define the real functional requirement, remove the decorative requirements, and let the supplier build a route around what actually matters.
Comparison table where relevant
| ITAR sourcing question | Why it matters | Bad assumption |
|---|---|---|
| Who can access files? | Controls technical data exposure | 'Email is fine' |
| Where is work performed? | Location control matters | No source visibility |
| Is subcontracting allowed? | Flowdown control required | Hidden outside process |
| How is data marked and stored? | Admin discipline matters | Treating it as ordinary work |
How to specify this in your RFQ
State clearly if the RFQ contains ITAR-controlled technical data and whether domestic-only manufacture is required. Ask suppliers to confirm compliant handling before you transmit the full package. That check belongs before the upload, not after it.
A clean RFQ does not just list requirements. It separates must-haves from preferences so the supplier can optimize where it is safe.
