0302.89.50.55 - Ocean perch

This HTS subheading, 0302.89.50.55, specifically classifies "Ocean perch" when imported fresh or chilled. This category falls under "Other fish" within the broader classification of "Fish, fresh or chilled, excluding fish fillets and other fish meat of heading 0304." The "ocean perch" designation is crucial, distinguishing it from freshwater varieties which would be classified under a different subheading.

To accurately classify goods under this code, it's important to differentiate "ocean perch" from its sibling categories at this level. For instance, while this code is for ocean perch, other subheadings at this level cover specific species such as smelts, cusk, shad, sturgeon, and sable fish. The key distinguishing factor is the species identity, as these other categories are reserved for their named fish types.

As this is a leaf node, there are no further subcategories under 0302.89.50.55. Therefore, the classification hinges entirely on the accurate identification of the imported product as ocean perch and ensuring it meets the criteria of being fresh or chilled. Any deviations, such as being frozen or processed into fillets, would necessitate classification under different HTS codes.
