0304.83.50 - Other

This HTS category, 0304.83.50, specifically covers "Other" frozen fillets and other meat of flat fish. It encompasses a broad range of flat fish species not otherwise specified in the preceding subheadings, provided they are presented as fillets or minced meat and have been frozen. This classification is crucial for distinguishing these products from more specifically defined flat fish categories.

The key differentiator for this category lies in its residual nature. It is intended for frozen flat fish meat that does not fit into the more granular classifications, such as the sibling category 0304.83.10, which details skinned, frozen-into-block flat fish intended for further processing like mincing or cutting into uniform pieces. Therefore, 0304.83.50 applies to frozen flat fish fillets or minced meat in other forms that do not meet the specific processing or weight requirements of the sibling.

To further refine classification within this "Other" category, several subcategories exist. These subdivisions are designed to provide more precise identification of commonly traded flat fish species. They include specific entries for Greenland turbot (Greenland halibut), sole, and flounder, allowing for more accurate tariff application. Any frozen flat fish meat that falls outside these specifically enumerated subcategories will then be classified under the residual "Other" classification at the deepest level of this node.
