Classification of frozen cockles under HS 0307.72
Frozen cockles are classified under HS code 0307.72. This classification is part of Chapter 3, which includes fish, crustaceans, and molluscs. Heading 0307 specifically covers molluscs, whether in shell or not, live, fresh, chilled, frozen, dried, salted, or in brine. The subheading 0307.7x is designated for clams, cockles, and ark shells. Within this group, 0307.72 is the specific code for these molluscs when they are presented in a frozen state. This classification applies to various families of cockles, including Cardiidae. The cockles can be imported or exported either in their shells or as shucked meat. The classification remains 0307.72 even if the cockles have been steamed or boiled in water before freezing, as this is considered a standard preservation step for frozen molluscs. The determination is based on the biological classification of the mollusc and the fact that freezing is the primary method of preservation for the shipment.

Codes often confused with 0307.72
Common mistake. Cockles are often misclassified under HS code 0307.71, which is for live, fresh, or chilled clams, cockles, and ark shells. Another common error is using HS code 1605.56, which covers prepared or preserved clams, cockles, and ark shells. If the cockles are canned, marinated, or part of a prepared dish, they must be moved to Chapter 16. Additionally, other molluscs like mussels (0307.32) or scallops (0307.22) are sometimes confused with cockles, but they have their own specific subheadings within heading 0307.

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).
