Classification of fresh cockles under HS 0307.71
HS code 0307.71 is used for the classification of fresh cockles and related molluscs. Chapter 3 of the Harmonized System covers fish, crustaceans, molluscs, and other aquatic invertebrates. Heading 0307 is specifically for molluscs, whether in shell or not, and whether live, fresh, chilled, frozen, dried, salted, or in brine. Subheading 0307.71 is a specific category for clams, cockles, and ark shells belonging to several families, including Arcidae, Cardiidae, and Veneridae. The primary criteria for this classification are the biological family and the state of the product, which must be live, fresh, or chilled. This includes cockles transported in seawater or kept on ice. The classification remains the same whether the cockles are presented in their shells or have been shucked (removed from the shell), as long as they have not been cooked or otherwise preserved.

Codes often confused with 0307.71
Common mistake. Cockles are frequently confused with other molluscs such as mussels (0307.31) or scallops (0307.21). A common technical error is misclassifying fresh cockles under 0307.72, which is reserved for frozen clams, cockles, and ark shells, or 0307.79, which covers those that are dried, salted, or in brine. Furthermore, if the cockles have been steamed or boiled in water, they must be classified under heading 1605 as prepared or preserved molluscs.

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).
