Skinned pollock fillets — other than Alaska pollock (Theragra chalcogramma) — packed in frozen blocks exceeding 4.5 kg and intended for mincing, grinding, or cutting into uniform pieces are classified here, distinguishing them from the Alaska pollock-specific block line in heading 030475. Atlantic pollock (Pollachius virens), also known as saithe or coalfish, is the species most likely to appear under this line in US trade. The over-4.5 kg block format signals an industrial processing destination, typically surimi analogs, fish cakes, or breaded portions. FDA prior notice and SIMP chain-of-custody records are required at entry.

The species is the controlling distinction: 0304751000 applies exclusively to Theragra chalcogramma (Alaska pollock), while 0304791010 covers all other pollock species — most commonly Pollachius virens (Atlantic pollock/saithe) — in the same skinned, over-4.5 kg frozen block format intended for further processing. Importers must provide species-level identification on commercial invoices and SIMP records to support the correct line.
Atlantic cod and related gadoids have been subject to SIMP requirements, but SIMP coverage is species-specific and has evolved. Importers should consult current NMFS guidance to confirm whether Pollachius virens is on the active SIMP species list at the time of entry, and maintain harvest documentation regardless, as CBP may request it during examination.
