Websites to check prior to proceeding with U.S. Exports and Imports

While many trade content providers, such as Customs Info, developed a single screen check tool to verify denied parties list, those forwarders, importers, and exporters with scarce resources have free links at their disposal that will get the job done:

1. OFAC’s Specially Designated Nationals List 
2. BIS’s Entity List
3. BIS’s Denied Persons List
4. BIS’s Unverified Parties List
5. State’s Nonproliferation Sanctions Lists
6. State’s Debarred Parties List

Another list maintained by the General Services Administration – Excluded Parties List System – may also be relevant in the case of federal contracts.
