0304.85.00.00 - Toothfish (Dissostichus spp.)

This HTS classification, 0304.85.00.00, specifically covers toothfish, scientifically identified as belonging to the genus *Dissostichus*. These are substantial, predatory fish found in the deep, cold waters of the Southern Hemisphere, commonly known by names such as Chilean sea bass or Patagonian toothfish. The classification applies to the meat of these fish, presented in various forms including fillets or other cut portions, provided they are fresh, chilled, or frozen.

Distinguishing this category from its siblings is crucial. While 0304.85.00.00 focuses exclusively on toothfish, other codes within 0304.8 cover different species or groups of fish. For instance, 0304.81 pertains to various types of salmon, 0304.82 to trout, 0304.83 to flatfish, and 0304.84 to swordfish. This precise designation ensures that toothfish are not misclassified with more common or commercially distinct fish species.

As a leaf node, this HTS category does not have further subdivisions. Therefore, classification under 0304.85.00.00 is determined solely by the identification of the fish as belonging to the *Dissostichus* genus and its presentation as fresh, chilled, or frozen meat. Exporters and importers should ensure accurate species identification to comply with customs regulations and facilitate smooth trade.
