Export screening a National Stock Number list (DEMIL codes)
NSN Lookup's check_export tool reads each item's DEMIL code and DEMIL Integrity Code from the federal catalog and marks it "no flag" or "export review required". It helps you see which lines need a closer look before an export. It is a screening aid, not a license determination.
Steps
Connect NSN Lookup
Connect NSN Lookup once: paste https://api.nsnlookup.com/mcp as a custom connector, then sign in with your free NSN Lookup account. Full click-by-click steps are on the setup page.
Add the list
One National Stock Number per row.
Run the screening
Use the prompt below. check_export takes up to 5 NSNs per call on the free plan and 25 on Developer, so long lists run in batches.
Review the flagged lines
Anything marked export review required goes to your export compliance process (EAR / ITAR classification and licensing).
Prompts to copy
Run NSN Lookup's check_export on every National Stock Number in the attached list. Return NSN, item name, DEMIL code, DEMIL Integrity Code and the screening result. Put flagged lines first and add a note that this is a screening aid, not a license determination.
