0305.31.01.00 - Tilapias (Oreochromis spp.), catfish (Pangasius spp., Silurus spp., Clarias spp., Ictalurus spp.), carp (Cyprinus spp., Carassius spp., Ctenopharyngodon idellus, Hypophthalmichthys spp., Cirrhinus spp., Mylopharyngodon piceus, Catla catla, Labeo spp., Osteochilus hasselti, Leptobarbus hoeveni, Megalobrama spp.), eels (Anguilla spp.), Nile perch (Lates niloticus) and snakeheads (Channa spp.)

This HTS category, 0305.31.01.00, specifically classifies dried, salted, or brined fish fillets derived from a defined list of freshwater and certain marine species. These include tilapias, catfishes, carps, eels, Nile perch, and snakeheads. The key distinguishing characteristic is that the fish must be presented in fillet form and prepared through drying, salting, or brining, with the exclusion of any smoking process.

This category is distinguished from its sibling, 0305.32.00, which covers dried, salted, or brined fillets from a different, specific set of marine families including Gadidae (cod) and Merlucciidae (hake). Furthermore, it differs from the "Other" sibling category, 0305.39, which serves as a residual category for any other fish fillets dried, salted, or brined, not falling under the more specific enumerations.

As this HTS code represents a leaf node, there are no further subcategories. Classification at this level hinges on both the species of fish and the specific preparation method (dried, salted, or in brine, excluding smoking) applied to the fillets. Precise identification of the fish species and confirmation of the absence of smoking are critical for accurate classification.
