0304.89.50.45 - Ocean catfish (wolf fish)

This HTS category encompasses frozen fillets and other fish meat, not minced, derived from fish not otherwise specified within Chapter 3. Specifically, it includes "Ocean catfish," also commonly known as wolf fish (Anarhichas spp.), when presented in frozen, filleted, or other meat forms. The key defining characteristic is the species of fish and its frozen state, distinguishing it from fresh or chilled preparations.

It is crucial to differentiate this category from its siblings. For instance, classifications for "Atlantic ocean perch," "Other ocean perch," "Orange roughy," and "Dolphin (Mahi mahi)" cover specific, named marine species. This category acts as a residual classification for frozen fish meat that does not fall under those more narrowly defined subheadings, provided it is not minced and originates from species other than those specifically listed.

As this is a leaf node within the HTS structure, there are no further subdivisions. Classification under 0304.89.50.45 is final for qualifying frozen ocean catfish (wolf fish) fillets and meat. Therefore, accurate identification of the species as ocean catfish (wolf fish) is paramount for correct classification and adherence to import/export regulations.
