Surimi (a refined, washed, and concentrated fish protein paste, typically from Alaska pollock or other whitefish) has its own dedicated tariff lines — including 0304991130 for Alaska pollock surimi and 0304991140 for other surimi — while plain minced fish meat that has not undergone the surimi refining process is classified under separate lines such as 0304991109 or 0304991185. The distinction matters because surimi commands different duty treatment and is used primarily as a processed seafood ingredient rather than a direct food product.

Yes. Several tariff lines under 030499 specifically apply to product in bulk containers greater than 6.8 kg each (for example, 0304991104 for surimi and 0304991194 for other fish meat in bulk), while other lines cover smaller retail or foodservice pack sizes. Importers should confirm the net weight per container against the applicable tariff line to avoid misclassification.
