0304.89.50 - Other

This HTS classification, 0304.89.50, encompasses "Other" frozen fillets and other fish meat (whether or not minced) of fish not specifically enumerated elsewhere within subheading 0304.89. This category applies to fish meat that is processed as fillets or minced, is preserved by freezing, and does not meet the specific criteria outlined in other subheadings. It serves as a residual category for a wide variety of frozen fish meat products.

Crucially, this classification differs from its sibling category, 0304.89.10, which is specifically reserved for skinned, frozen fish blocks weighing over 4.5 kg, intended for subsequent mincing, grinding, or cutting into uniform pieces. Category 0304.89.50, conversely, is not limited to specific weight blocks or intended end-use in further processing in the same manner, and can include fish meat that is already cut into smaller portions or minced, as long as it is otherwise within the scope of frozen fillets and other fish meat.

This subheading is further subdivided to provide more granular classification for various types of frozen fish meat. Subcategories include specific designations for "Fresh-water fish," as well as distinct classifications for species such as Atlantic ocean perch, other ocean perch, ocean catfish (wolf fish), orange roughy, dolphin (mahi mahi), and cusk. The existence of these specific subcategories reflects the trade volume and the need for precise identification of different fish species for customs purposes, while the residual category "Other" (0304.89.50.91) captures any remaining frozen fish meat products not otherwise detailed.
