What HS 0303.55 covers

This code covers frozen jack and horse mackerel, a significant commodity in global seafood trade. These fish are often caught in large quantities by industrial fishing fleets and then frozen whole or in large blocks for preservation and transport. Major importers are countries with high per capita fish consumption or those that process fish for re-export, particularly in Africa and Asia, where these species are a staple food source due to their affordability and nutritional value. Exporters typically include countries with extensive coastlines and advanced fishing industries, such as Peru, Chile, and various European nations. Key things to know include the importance of sustainable fishing practices to prevent overfishing, the role of cold chain logistics in maintaining product quality, and the impact of international trade agreements and tariffs on market access. The trade in these frozen fish supports livelihoods in many coastal communities and provides an essential protein source globally, making it a vital component of the international food supply chain.

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).
