Classification of fresh trout fillets under HS 0304.42
Fresh trout fillets are classified under HS code 0304.42. This classification is found within Chapter 3 (Fish and Crustaceans) and Heading 0304, which is dedicated to fish fillets and other fish meat. The subheading 0304.42 specifically targets fresh or chilled fillets of trout species, including Salmo trutta and various Oncorhynchus species like Rainbow trout. A fillet is defined by the Harmonized System as a strip of meat cut parallel to the backbone, which may or may not have the skin or pin bones removed. The "fresh or chilled" designation means the product has been kept at a low temperature (usually between 0°C and 4°C) to maintain freshness but has never been frozen. Under General Rule of Interpretation 1, the classification is driven by the specific description of the product as a fillet and its biological species. This code is essential for monitoring the trade of high-value processed fish products and ensures that fillets are distinguished from whole fish or minced meat for both statistical and regulatory purposes.

Codes often confused with 0304.42
Common mistake. A frequent misclassification occurs when fresh trout fillets are entered under 0302.11. However, 0302.11 is strictly for whole or headed/gutted trout. Once the fish is filleted, it must move to Heading 0304. Another common error is using 0304.82, which is the code for frozen trout fillets. Additionally, if the trout fillets have been smoked, they must be classified under 0305.43 rather than 0304.42. Finally, trout meat that has been minced or ground should be classified under 0304.52 (fresh trout meat, excluding fillets) rather than 0304.42.

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).
