HS code for Fresh bigeye tuna: 0302.34
Fish, fresh or chilled, bigeye tunas (Thunnus obesus), excluding fillets, fish meat of 0304, and edible fish offal of subheadings 0302.91 to 0302.99.
Classification of fresh bigeye tuna under HS 0302.34
Fresh bigeye tuna is classified under HS code 0302.34, a designation that falls within Chapter 3 of the Harmonized System, which covers fish and crustaceans, molluscs, and other aquatic invertebrates. Heading 0302 is specifically reserved for fish that are fresh or chilled, excluding fish fillets and other fish meat that fall under heading 0304. The subheading 0302.34 is precisely allocated to Bigeye tunas, known scientifically as Thunnus obesus. This classification is determined by both the species of the fish and its state of preservation. For a product to be classified under this code, it must be either whole or in a form that has been gutted or headed, but it must not be cut into fillets or steaks, which would shift the classification to 0304. The distinction between "fresh" and "chilled" is also critical; fresh fish are those that have not been processed, while chilled fish have had their temperature lowered to near freezing to prevent spoilage during transport. If the tuna were frozen to a temperature of -18 degrees Celsius or lower, it would instead be classified under heading 0303.

Codes often confused with 0302.34
Common mistake. Bigeye tuna is often misclassified under 0303.44 if it has been frozen. Another common error is using 0304.87 for fresh bigeye tuna fillets or steaks, as heading 0302 only applies to whole or minimally processed fish. Furthermore, it may be confused with other tuna species like Albacore (0302.31) or Yellowfin (0302.32) if the species is not correctly identified by the importer.

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).
