0304.89.50.55 - Dolphin (Mahi mahi) (Coryphaena spp.)

This HTS classification covers frozen fillets and other meat, whether minced or not, derived from fish not specifically enumerated under preceding subheadings within the "Other" category. This includes fish meat that does not fall under fresh-water fish, Atlantic ocean perch, other ocean perch, ocean catfish, or orange roughy. The primary characteristic is that the product must be in a frozen state.

The key distinction of this category lies in its residual nature. It captures all frozen fish fillets and meat that are not otherwise specifically listed at this granular level. Therefore, if a particular species of frozen fish fillet or meat does not have a dedicated HTS code, and it is not a fresh-water fish or one of the specifically named ocean species, it will likely be classified here.

As this is a terminal classification (a leaf node), there are no further subdivisions. Classification at this level is determined by the exclusion of the specific species listed in the sibling categories. Importers and exporters should carefully review the preceding subheadings to ensure that their product is not more specifically classified elsewhere before assigning it to this residual category.
