0304440010 covers Atlantic cod (Gadus morhua) specifically, while 0304440015 captures fillets of all other cod species not classified as Atlantic cod. This distinction matters because Atlantic cod and Pacific cod (Gadus macrocephalus) are commercially interchangeable in some markets but carry separate tariff lines; species identification on invoices must be precise.

All imported fish fillets require FDA Prior Notice submission before arrival and are subject to FDA port-of-entry examination. Shipments must originate from facilities registered with FDA. Iceland and Norway are not US free-trade-agreement partners, so standard MFN duty rates apply. Importers should also verify that harvest documentation satisfies any applicable IUU fishing regulations and that labeling meets FDA seafood identity standards.

No. Alaska pollock (Gadus chalcogrammus) is classified under a different HTS heading covering Pacific groundfish. The pollock line at 0304440025 within heading 030444 covers pollock of the Gadidae family harvested in Atlantic or other non-Pacific fisheries, such as Norwegian pollock. Importers should confirm species and origin to ensure correct classification.
