Classification of frozen bluefin tuna under HS 0303.45

The classification of frozen bluefin tuna under HS code 0303.45 is governed by specific species identification and the state of preservation. Heading 0303 applies to fish that are frozen, excluding fillets and other fish meat of heading 0304. Subheading 0303.45 specifically identifies Atlantic bluefin tuna (Thunnus thynnus) and Pacific bluefin tuna (Thunnus orientalis). This classification is precise and excludes other tuna species like Albacore or Yellowfin, which have their own dedicated subheadings. The product must be frozen to a temperature that ensures the core is maintained at a level where biological activity is suspended, typically -18 degrees Celsius or lower. Furthermore, the fish must be presented whole, headed, gutted, or in pieces that still contain the bone; once the bones are removed and it is presented as a fillet or steak, it moves to heading 0304. The classification follows GRI 1 and GRI 6, ensuring the species-specific subheading is applied correctly.

Codes often confused with 0303.45

Common mistake. Bluefin tuna is often misclassified under HS code 0303.46, which is specifically for Southern bluefin tuna (Thunnus maccoyii). While they are all bluefin, the geographical and biological distinction is mandatory in the HS nomenclature. Another common error is using 0304 for whole frozen fish; 0304 should only be used if the fish is filleted or the meat is removed from the bone. Finally, if the tuna is prepared or preserved (e.g., canned or cooked), it falls under heading 1604 rather than Chapter 3.

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).
