0304.92 - Toothfish (Dissostichus spp.):

This HTS classification covers frozen toothfish meat, including fillets and minced portions, derived from species belonging to the genus *Dissostichus*. Toothfish, commonly known as Chilean Sea Bass, is characterized by its rich, oily flesh and is primarily sourced from Antarctic and sub-Antarctic waters. The key defining element for this category is the species of origin, *Dissostichus spp.*, ensuring that only this specific type of fish meat is classified here.

It's important to distinguish this category from its siblings. While they all fall under frozen fish meat that is "other," 0304.92 is exclusively for toothfish. Other sibling categories at this level classify frozen swordfish, tilapias, catfish, carp, eels, Nile perch, snakeheads, Alaska pollock, various deep-sea fish from specific families, and dogfish/sharks. Each of these has its own distinct species or family designation.

Within the 0304.92 classification, further subdivisions exist to account for the presentation of the frozen toothfish meat. The primary distinction is made based on packaging. Subcategory 0304.92.10.00 applies to toothfish presented in bulk or in immediate containers whose individual weight, including contents, exceeds 6.8 kilograms. Conversely, 0304.92.90.00 encompasses all other presentations, typically smaller retail packaging or individually wrapped portions.
