HS code for Fresh molluscs: 0307.91
Molluscs, n.e.c. in heading 0307, whether in shell or not, live or fresh, chilled.
Classification of fresh molluscs under HS 0307.91
Fresh molluscs that are not specifically named in other subheadings are classified under HS code 0307.91. This code is part of Chapter 3, which encompasses fish, crustaceans, molluscs, and other aquatic invertebrates. Heading 0307 specifically deals with molluscs, whether in shell or not, live, fresh, chilled, frozen, dried, salted, or in brine. The subheading 0307.91 serves as a residual category for molluscs that do not have their own specific subheadings (such as oysters, scallops, mussels, or cuttlefish) and are presented in a live, fresh, or chilled state. Classification depends on the biological species and the method of preservation. To qualify for this code, the product must not have been frozen or subjected to any cooking process. The term "chilled" refers to products that have had their temperature reduced to near 0°C without being frozen. This classification follows GRI 1, which prioritizes the specific terms of the headings, and GRI 6 for the subheading level.

Codes often confused with 0307.91
Common mistake. A frequent misclassification occurs when fresh molluscs are confused with frozen ones, which fall under 0307.92. Additionally, if the molluscs are dried, salted, or in brine, they must be classified under 0307.99. Importers often mistakenly use specific codes like 0307.11 (oysters) or 0307.31 (mussels) for general molluscs. It is also critical to distinguish between raw molluscs and prepared or preserved ones; if the product has been cooked or canned, it moves to Chapter 16, specifically heading 1605.

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).
