HS code for Chilled bigeye tuna: 0302.34

Classification of chilled bigeye tuna under HS 0302.34
Chilled bigeye tuna (Thunnus obesus) is classified under HS code 0302.34. This classification is part of Chapter 3, which covers fish and aquatic invertebrates, and Heading 0302, which is reserved for fresh or chilled fish. The Harmonized System provides specific subheadings for different tuna species to allow for precise monitoring of global fish stocks and trade. Bigeye tuna is a high-value species often used in the sashimi market, and its classification under 0302.34 requires that the fish be fresh or chilled. Chilling typically involves packing the fish in ice or using refrigerated seawater to maintain a temperature near 0°C. The fish may be whole, or it may be gilled and gutted, but it must not be filleted or otherwise processed into meat portions, as those products would fall under heading 0304.

Codes often confused with 0302.34
Common mistake. Bigeye tuna is frequently misclassified with other tuna species. For example, Albacore tuna is 0302.31 and Yellowfin tuna is 0302.32. Accurate species identification is critical for customs compliance. Another common error is using the code for frozen bigeye tuna, which is 0303.44. Because bigeye tuna is often "super-frozen" at -60°C for the sushi trade, it frequently falls under the frozen category rather than the chilled one. Finally, if the tuna is presented as steaks or fillets, it must be classified under HS code 0304.44 (for fresh/chilled fillets) or similar codes in heading 0304.

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).
