What HS 0304.83 covers
This HS code encompasses frozen fillets derived from various flatfish species, a significant category in global seafood trade. These products are highly valued for their delicate texture and mild flavor, making them popular in both retail and food service sectors worldwide. Major fishing nations in the North Atlantic, Pacific, and other regions supply these fillets, which undergo processing like skinning, deboning, and freezing for preservation. Importers typically include countries with high seafood consumption like the United States, Japan, and various European Union members, where flatfish are a staple. Exporters often include countries with strong fishing industries and processing capabilities, such as China, Norway, and Iceland. Key considerations in this trade involve sustainable fishing practices, traceability, and adherence to food safety standards, as consumer demand for responsibly sourced seafood continues to grow.

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).
