Importers of Dried, Salted, or Brined Fish Fillets, Not Smoked (Other Species) paid $65K in duties in August 2026, an average duty rate of 9.68% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataHerring and mackerel fillets preserved by drying, salting, or brining — but not smoked — are the commercially prominent species in this residual heading, each assigned dedicated lines based on container size: herring and mackerel fillets in containers of 6.8 kg or less (0305392000 and 0305394000) are distinguished from bulk-packed herring (0305396110) and other fish fillets (0305396180). The container-size split reflects the retail versus food-service and industrial processing distinction that recurs throughout Chapter 3. Mackerel fillets in brine are widely traded for canned and ready-to-eat applications across European and Asian markets. FDA seafood HACCP requirements and prior notice apply to all entries under this heading.

The US tariff schedule uses a 6.8 kg container threshold to distinguish retail-oriented packs from bulk industrial or food-service packs. Herring fillets in containers of 6.8 kg or less classify under 0305392000, while bulk-packed herring fillets fall under 0305396110. This distinction can affect the applicable duty rate, so importers should confirm the net weight per individual container — not the total shipment weight — at the time of entry.
Classification as 'in brine' generally requires that the fish be immersed in or packed with a salt solution as the primary preservation medium. Vacuum-packed mackerel with a light salt rub but no free brine liquid may be considered 'salted' rather than 'in brine,' which can affect both the applicable tariff line and labeling requirements. Importers with borderline preservation methods should seek a binding ruling from CBP to confirm the correct classification.
