Classification of chilled flatfish fillets under HS 0304.43
Chilled flatfish fillets are classified under HS code 0304.43. This classification is governed by Chapter 3 of the Harmonized System. Heading 0304 is specifically designated for fish fillets and other fish meat (whether or not minced), fresh, chilled, or frozen. Within this heading, the 0304.4x series is reserved for fresh or chilled fillets. Subheading 0304.43 specifically identifies fillets from flatfish belonging to the families Pleuronectidae, Bothidae, Cynoglossidae, Soleidae, Scophthalmidae, and Citharidae. A fillet is defined as a strip of meat cut parallel to the backbone of the fish. The \"chilled\" designation requires the product to be kept at a low temperature without reaching a frozen state, which is a critical distinction for both shelf-life and customs valuation.

Codes often confused with 0304.43
Common mistake. The most common misclassification is confusing chilled fillets (0304.43) with frozen fillets, which are classified under 0304.83. Another error involves classifying whole or gutted chilled flatfish under this code; whole fish belong in heading 0302 (specifically 0302.21 to 0302.29). Additionally, if the fish meat is minced rather than filleted, it may fall under 0304.59, even if it is from a flatfish species.

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).
