0304.89.10.10 - Ocean catfish (wolf fish)

This HTS classification covers ocean catfish, also known as wolf fish, specifically when presented as frozen fillets or other fish meat. The key characteristics for this subcategory are that the fish meat must be skinned, and it can be divided into pieces. Critically, it is imported frozen into blocks, with each block weighing over 4.5 kilograms. The intended use of this product is for subsequent processing, such as mincing, grinding, or cutting into pieces of uniform weights and dimensions.

This specific classification for ocean catfish distinguishes it from its siblings which include other types of fish meat classified under 0304.89.10. For instance, pickerel (0304.89.10.15) and sauger (0304.89.10.20) represent distinct species. Similarly, perch, though listed without a specific code at this juncture, would represent another group of fish meat classified separately. The residual category, "Other" (0304.89.10.90), captures all other frozen fish fillets and meat that do not fit the more specific descriptions, including ocean catfish not meeting the stated block weight or processing intent.

As this is a leaf node within the HTS structure, there are no further subcategories under 0304.89.10.10. Therefore, the classification is definitive for ocean catfish meeting all the outlined criteria: skinned, frozen into blocks exceeding 4.5 kg, and intended for further processing into uniform pieces. Classification is solely determined by the species, the form of the meat (fillets or other meat), its temperature (frozen), and the specific processing and packaging requirements (skinned, block weight, intended use).
