HS code 0304.46 is the 6-digit subheading for fish fillets, fresh or chilled, toothfish (Dissostichus spp.). It is used for patagonian toothfish fillets, antarctic toothfish fillets, chilean Sea Bass fillets, toothfish steaks and skin-on toothfish fillets.
What HS 0304.46 covers
This HS code specifically covers fresh or chilled fillets of toothfish (Dissostichus spp.), which primarily includes Patagonian toothfish and Antarctic toothfish, often marketed under the trade name 'Chilean Sea Bass.' This is an exceptionally high-value product in the global seafood trade, celebrated for its rich, buttery flavor and firm, flaky white flesh. It is a staple in high-end restaurants and specialty seafood markets in affluent countries. The trade is characterized by stringent regulations due to the deep-water habitat of these species and their vulnerability to illegal fishing. Traceability and compliance with international conservation measures, such as those from CCAMLR (Commission for the Conservation of Antarctic Marine Living Resources), are paramount. Importers are typically luxury food distributors and gourmet retailers in North America, Japan, and Europe. Exporters are countries with legal, regulated toothfish fisheries, primarily in the Southern Ocean. Maintaining the cold chain is crucial for this premium, delicate product.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
