0303.89.00.43 - Other

This HTS category, 0303.89.00.43, encompasses frozen freshwater fish not specifically listed in preceding subheadings. It serves as a residual category for a variety of commonly consumed freshwater species that do not fall under more specific classifications. The key criterion for inclusion here is that the fish must be frozen, and of freshwater origin.

This subheading distinguishes itself from its siblings by its broad scope covering "other" freshwater fish. For example, while 0303.89.00.40 specifically covers Tilapias (excluding Oreochromis spp.), this category would include other freshwater species like catfish, carp, or various types of trout if not classified elsewhere. It also differentiates from categories focused on saltwater fish or specific edible fish offal, which are handled under different HTS codes within Chapter 03.

As this is a leaf node, there are no further subcategories branching from 0303.89.00.43. Therefore, the classification decision relies heavily on a thorough examination of the specific species of frozen freshwater fish and ensuring it does not meet the criteria for any more granular subheading. This requires consulting reliable taxonomic classifications and ensuring the fish is not an offal product.
