Fresh or Chilled Tuna (Other), Excluding Fillets, Livers & Roe

Species such as longtail tuna (Thunnus tonggol), blackfin tuna (Thunnus atlanticus), and bullet tuna (Auxis rochei) are examples that lack dedicated HTS headings and would default to 030239. Importers should confirm the scientific name of the species with the exporter and cross-reference it against the named-species headings (030231–030236) before filing entry documents to ensure the residual heading is genuinely appropriate.

NOAA's Seafood Import Monitoring Program covers tunas of the genus Thunnus and related species broadly. Importers should verify with NOAA's current SIMP species list whether the specific tuna species in a shipment triggers reporting obligations, as coverage can depend on both the genus and the fishing gear type. When in doubt, filing harvest event data proactively is advisable to avoid compliance gaps.
