Smoked Fish, Including Fillets, NESOI

Classification starts with species identification. Herrings go to 030542, trout to 030543, salmon to 030541, and tilapia/catfish/Nile perch/snakeheads to 030544. Only smoked fish that does not fit those species-specific headings — such as mackerel, cod, haddock, hake, pollock, cusk, and others — falls under 030549. Misclassification is common when a product contains multiple species or when common trade names obscure the scientific species identity.

Both smoked pollock and smoked cod are captured within the same 10-digit line (0305494020), which covers cod, cusk, haddock, hake, and pollock together. There is no further subdivision at the tariff-line level between these species, though the commercial invoice must still identify the species for FDA and country-of-origin labeling purposes. Consult a licensed customs broker if the product is a blend or if species documentation is incomplete.
