Bolts, Nuts, Screws, Rivets, Washers & Other Turned Products

Aerospace fasteners generally require material test reports (MTRs) conforming to ASTM, AMS, or equivalent specifications, first-article inspection documentation, and traceability to the raw material heat lot. Buyers should also verify that the foreign manufacturer holds relevant quality management certifications (e.g., AS9100) and that the parts are not counterfeit — a known risk in the aerospace fastener supply chain.

Importers must match the specific HTS 10-digit code and country of origin against the Commerce Department's active antidumping and countervailing duty order list. Because fastener orders have been issued against multiple countries and cover specific product subsets, a thorough scope analysis — ideally with input from a licensed customs broker or trade attorney — is recommended before each new sourcing arrangement.
