0304.49.01 - Other

This category, HTS code 0304.49.01, encompasses "Other" fresh or chilled fillets of fish that do not fall under the more specific subheadings within 0304.4. It serves as a residual category for fish fillets that are not from Pacific or Atlantic salmon, trout, flatfish, or specific families like Gadidae, nor swordfish. The primary classification criterion here is the species of fish, where fillets of species not explicitly listed in preceding sibling categories are directed to this subheading.

To differentiate, this category is distinct from its siblings which are dedicated to particular types or families of fish with established import/export trade volumes and classifications. For instance, 0304.41.00 specifically covers various salmon species, while 0304.42.00.00 is for trout. This "Other" category is for the remaining unassigned fresh or chilled fish fillets.

Within this subheading, further distinctions are made to provide greater specificity. The subcategories include provisions for "Fresh-water fish," with further breakdowns for specific species like Atlantic ocean perch and cusk. A final residual category, "Other," exists within this level to capture any remaining fresh or chilled fish fillets that do not fit into the more detailed sub-classifications. This hierarchical structure ensures comprehensive coverage of all fresh or chilled fish fillets.
