HS Code 0303.83 – Fish; frozen, toothfish (Dissostichus spp.), excluding fillets, livers, roes, and edible fish offal of subheadings 0303.91 to 0303.99
HS code 0303.83 is the 6-digit subheading for fish, frozen, toothfish (Dissostichus spp.), excluding fillets, livers, roes, and edible fish offal of subheadings 0303.91 to 0303.99. It is used for frozen whole Patagonian toothfish, frozen gutted Antarctic toothfish, frozen toothfish steaks (bone-in), frozen toothfish portions (bone-in) and frozen toothfish collars.
What HS 0303.83 covers
This HS code specifically targets frozen toothfish, primarily Patagonian toothfish (also known as Chilean sea bass) and Antarctic toothfish, in forms other than fillets, livers, roes, or offal. These highly prized deep-sea fish are a luxury seafood item, commanding premium prices in international markets. Major importers are high-end restaurants, gourmet food distributors, and specialty retailers in affluent countries like the United States, Japan, and China. Exporters are typically nations with access to the Southern Ocean fisheries, such as Chile, Argentina, Australia, and South Africa, operating under strict international quotas set by CCAMLR (Commission for the Conservation of Antarctic Marine Living Resources). Key aspects of this trade involve rigorous traceability systems to combat IUU fishing, CITES regulations for certain species, and maintaining the integrity of the cold chain due to the fish's high value and delicate nature. The sustainability and legality of the catch are paramount for market access.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
