0304.75 - Alaska pollock (Theragra chalcogramma):

This HTS category, 0304.75, specifically covers frozen fillets of Alaska pollock (Theragra chalcogramma). These fillets are derived from fish belonging to the families Gadidae, which also include other commercially important white fish. The classification is distinct from its sibling categories which cover other specific species of cod, haddock, coalfish, and hake, as well as a general "other" category for fillets from these families.

The distinction lies in the precise species of fish. While all siblings fall under the broader heading of frozen fillets from specific Gadidae families, 0304.75 is exclusively for Alaska pollock. This specificity is crucial for accurate customs reporting and duty assessment.

This category is further subdivided to differentiate based on processing and intended use. The subcategory 0304.75.10.00 covers Alaska pollock fillets that have been skinned, frozen into blocks weighing over 4.5 kg, and are specifically imported for further processing into minced, ground, or uniformly cut pieces. The subcategory 0304.75.50.00 encompasses all other frozen Alaska pollock fillets that do not meet the specific processing criteria of the first subcategory.
