Last updated: August 2026 dataFrozen fillets from the cod-order families — including Gadidae (cod, haddock, hake), Merlucciidae (merlucza/whiting), Macrouridae, and several related families — are grouped under this HS6 heading when they fall outside the Alaska pollock-specific heading. Argentina and Chile are the leading suppliers, reflecting the importance of South Atlantic hake (Merluccius spp.) in this trade flow, with China and South Africa also significant sources. The US tariff schedule subdivides the heading by species (pollock NESOI, whiting/Merluccius spp.) and by physical form — particularly the over-4.5 kg skinned frozen block format used for industrial mincing — across five 10-digit lines. All shipments are subject to FDA prior notice and SIMP harvest documentation requirements.

Heading 030475 is reserved exclusively for Alaska pollock (Theragra chalcogramma); this heading (030479) captures all other frozen fillets from the same broad cod-order families, including Atlantic cod, haddock, Pacific cod, hake (Merluccius spp.), whiting, and related species. Importers must confirm species identity — typically via supplier certificates and SIMP records — to ensure product is not misclassified between the two headings.
Both countries operate large-scale hake (Merluccius hubbsi and M. gayi) fisheries in the South Atlantic and Southeast Pacific, and their processing sectors produce the skinned frozen block format that US seafood manufacturers require for minced fish products. The geographic proximity of these fisheries to productive cold-water upwelling zones supports consistent year-round supply, making them the primary sources for this heading.
