Classification of chilled trout fillets under HS 0304.42

Chilled trout fillets are classified under HS code 0304.42. This code is situated within heading 0304, which covers fish fillets and other fish meat. According to the Explanatory Notes to the Harmonized System, fillets are defined as the fleshy parts of the fish cut parallel to the backbone. For trout, this includes species such as Salmo trutta and Oncorhynchus mykiss. The classification 0304.42 is specific to fresh or chilled fillets. If the fillets were frozen, they would be classified under 0304.82. The distinction is vital because different tariff rates or sanitary regulations may apply based on the preservation method. Furthermore, the fillets must be presented in a fresh or chilled state, typically packed in ice or refrigerated to maintain quality during transport. This classification excludes fish that has been minced or processed into "other meat" forms, which would fall under 0304.52. The accuracy of this classification is paramount for compliance with international trade agreements and for the collection of accurate species-specific trade data.

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).
