0303.89.00.64 - Ocean perch

This HTS code, 0303.89.00.64, specifically classifies "Ocean perch" when imported frozen, excluding fish fillets and other fish meat of heading 0304. This category falls under the broader scope of frozen fish, excluding edible fish offal, and within that, it encompasses "other fish" not specifically enumerated in preceding subheadings.

To distinguish this classification, note that sibling categories at this level include distinct types of fish such as smelts, cusk, shad, sturgeon, and Atka mackerel, each with their own specific HTS codes. This code for Ocean perch is for fish that do not fit into those more narrowly defined categories but are still frozen and not processed into fillets or other meat forms.

As this is a leaf node, there are no further subcategories under 0303.89.00.64. Therefore, classification under this code relies on the accurate identification of the fish as "Ocean perch" and confirmation that it meets the general criteria of being frozen and not being fish fillets or other fish meat of heading 0304. Importers should ensure that the merchandise precisely matches the description and context provided.
