Fish Fillets, Fresh or Chilled (NESOI)

Classification among the eight lines — covering pickerel (0304490106), freshwater whitefish (0304490109), tilapia (0304490112), other freshwater fish (0304490115), Atlantic ocean perch (0304490120), cusk (0304490125), and two NESOI catch-alls — depends first on whether the species is freshwater or marine, then on whether it matches a named species. Importers should use the scientific name on the commercial invoice and consult a licensed customs broker to confirm the correct line, as misclassification between freshwater and saltwater provisions or between named and NESOI lines can trigger liquidation adjustments.

Shipments from Canada benefit from streamlined border procedures under USMCA, but FDA seafood HACCP requirements still apply regardless of origin. The Canadian establishment must be registered with FDA and maintain a HACCP plan covering the specific species being exported. Country-of-origin labeling under COOL rules applies at retail, and importers should ensure the commercial invoice clearly identifies the species and its freshwater or saltwater origin to support correct 10-digit classification.
