What HS 0303.46 covers
This HS code specifically covers whole frozen southern bluefin tuna (Thunnus maccoyii), another highly sought-after species in the premium seafood market, particularly for sashimi. Southern bluefin shares the high value and culinary prestige of its Atlantic and Pacific cousins, known for its rich, fatty meat. Its trade is subject to stringent international regulations due to its endangered status, with quotas managed by the Commission for the Conservation of Southern Bluefin Tuna (CCSBT). Major exporters are typically countries with significant aquaculture operations or highly regulated wild fisheries in the Southern Hemisphere, such as Australia, New Zealand, and South Africa. Similar to other bluefin species, the primary destination for southern bluefin is Japan, where it is a staple of high-end sushi and sashimi restaurants. Critical factors in this trade include maintaining an unbroken cold chain to preserve quality, rigorous traceability systems to ensure compliance with conservation measures, and adherence to CITES regulations. The market is characterized by high prices, limited supply, and a strong focus on sustainability and legality.

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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
