0304.99.91.90 - Ocean

This HTS classification, 0304.99.91.90, specifically covers "Ocean" fish meat that is processed and then frozen. This designation applies to frozen fish fillets and other fish meat, including minced varieties, that do not fit into more specific subheadings within the 0304 chapter. The key characteristic for this category is that the fish originated from the ocean and has undergone freezing after initial processing.

Distinguishing this category from its sibling, 0304.99.91.92 (also described as "Other"), relies on the specific origin of the fish and the absence of further distinguishing characteristics that would place it in a more granular subheading. While both are broad categories for "Other" frozen fish meat, this node is intended for instances where the fish is marine in origin and no other specific descriptive elements are applicable for further breakdown.

As this is a leaf node in the HTS structure, there are no further subcategories under 0304.99.91.90. Therefore, the classification is definitive for ocean fish meat that is frozen and does not fall under any more narrowly defined classifications within the broader "fish meat, frozen, other" umbrella. Practical classification relies on confirming the marine origin of the fish and its frozen state, in conjunction with the absence of any specific processing or species identification that would lead to a different HTS code.
