Frozen Fish Meat (Except Fillets), NESOI

Surimi — the refined, frozen fish protein paste used in imitation crab, seafood sticks, and analog products — is the commercially dominant product within this broad residual heading, with dedicated lines for Alaska pollock surimi (0304991130) and other surimi (0304991140), as well as bulk minced surimi (0304991104). Beyond surimi, the heading captures frozen tuna meat in bulk (0304991190), freshwater fish meat including pike and whitefish, and a wide range of ocean and non-ocean fish meat not covered by more specific headings. Chile, Indonesia, and Vietnam are the leading US import suppliers, reflecting the geographic diversity of species covered. The breadth of this heading makes precise classification — particularly distinguishing minced from non-minced forms and bulk from retail pack sizes — a recurring challenge for importers.
