Classification of frozen clams under HS 0307.72
Frozen clams are classified under HS code 030772. This code is part of Chapter 3, which covers fish and crustaceans, molluscs, and other aquatic invertebrates. Heading 0307 is specifically for molluscs, whether in shell or not, and includes various states such as live, fresh, chilled, frozen, dried, salted, or in brine. Within this heading, the 03077x series is dedicated to clams, cockles, and ark shells belonging to families such as Arcidae, Arcticidae, Cardiidae, Donacidae, Hiatellidae, Mactridae, Mesodesmatidae, Myidae, Semelidae, Solecurtidae, Solenidae, Tridacnidae, and Veneridae. The subheading 030772 specifically identifies these molluscs when they are in a frozen state. The classification process requires identifying the biological family of the mollusc and confirming that the preservation method is freezing. This code applies to both clams in their shells and shucked clam meat, provided that no additional preparation, such as cooking or seasoning, has taken place. The use of this specific code allows for the detailed tracking of mollusc trade and ensures that food safety regulations specific to frozen shellfish are correctly applied at international borders.

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).
