0304.51.01 - 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, 0304.51, specifically covers a diverse group of fresh or chilled fish meat and fillets that do not fall under broader family-based classifications. It encompasses popular species such as tilapias (Oreochromis spp.), a variety of catfish (including Pangasius spp. and Silurus spp.), carp (Cyprinus spp. and others), eels (Anguilla spp.), Nile perch (Lates niloticus), and snakeheads (Channa spp.). The key characteristic is that these are processed forms of these specific fish, presented either fresh or chilled for consumption.

Distinct from its sibling categories, which are organized by broader taxonomic families like Salmonidae (0304.52) or specific commercial fish like swordfish (0304.54) and toothfish (0304.55), 0304.51 focuses on a collection of commonly traded but taxonomically varied species. This ensures that these particular fish meats and fillets are correctly identified and distinguished from their more broadly defined relatives or commercially prominent counterparts.

Within this category, further subheadings provide for more granular classification based on the specific type of fish. This includes subdivisions for Ictalurus spp. catfish, Pangasius spp. (commonly known as basa), Nile Perch, and Tilapias. A residual subheading (0304.51.01.90) is available for other species that fit the general description but are not individually itemized. This detailed breakdown allows for precise tracking and tariff application based on the precise species of fish.
