What HS 0307.72 covers

This HS code pertains to frozen clams, cockles, and ark shells, offering a significantly longer shelf life and greater flexibility in global distribution compared to their live or fresh counterparts. Freezing enables these popular bivalves to reach markets far from their harvesting grounds, making them accessible to a wider consumer base. Importers include food service providers, retailers, and food processors who utilize them in a variety of culinary applications, from seafood stews and pasta dishes to fried clam strips. Exporters are typically countries with large-scale fishing or aquaculture operations equipped with efficient processing and freezing infrastructure. Key aspects of this trade involve maintaining an unbroken cold chain, employing proper freezing techniques to preserve texture and flavor, and adhering to stringent international food safety standards.

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).
