0304.46.00.00 - Toothfish (Dissostichus spp.)

This HTS classification, 0304.46.00.00, specifically covers fresh or chilled fillets and other meat of toothfish, belonging to the genus *Dissostichus*. Toothfish are large, deep-sea predatory fish often referred to by various trade names such as Chilean Sea Bass or Patagonian Toothfish. This category is distinct from other fresh or chilled fish fillets in that it exclusively pertains to this particular genus.

To differentiate this category from its siblings, consider the following. While siblings such as 0304.41.00 and 0304.42.00.00 classify fillets of salmon and trout respectively, and 0304.43.00 covers flatfish, this classification is solely for *Dissostichus* species. Similarly, it is separate from 0304.44.00, which encompasses fish from a different set of families, and 0304.45.00.00, which specifically designates swordfish fillets. The defining characteristic for inclusion in 0304.46.00.00 is the scientific genus of the fish.

As this classification is a leaf node, it does not have further subcategories. Therefore, the focus for classification purposes under 0304.46.00.00 rests entirely on the accurate identification of the fish as belonging to the *Dissostichus* genus and that the product is presented as fresh or chilled fillets or other meat. Proper documentation, including species identification, is crucial for correct classification.
