HS code for Dried molluscs: 0307.99
Molluscs, n.e.c. in heading 0307, whether in shell or not, dried, salted, in brine, or smoked, cooked or not before or during the smoking process.
Classification of dried molluscs under HS 0307.99
Dried molluscs that are not specifically named in other subheadings are classified under HS code 0307.99. Chapter 3 of the Harmonized System covers fish, crustaceans, and molluscs. Heading 0307 is dedicated to molluscs, whether in shell or not, and includes those that are live, fresh, chilled, frozen, dried, salted, or in brine. Subheading 0307.99 is a residual category for "other" molluscs and aquatic invertebrates that are dried, salted, or in brine, and which are not covered by the specific subheadings for oysters, scallops, mussels, cuttlefish, squid, octopus, clams, abalone, or snails. This code is used for a wide variety of marine species that are preserved through drying. The product may be cooked before or during the drying process if it is part of a smoking process, but generally, cooked molluscs that are not smoked or dried in a specific manner may fall under Chapter 16. The classification depends heavily on the species and the level of processing.

Codes often confused with 0307.99
Common mistake. Dried molluscs are frequently misclassified under 0307.49 (dried cuttlefish and squid) or 0307.59 (dried octopus) because these are the most common dried molluscs in trade. If the species is not squid or octopus, it must be checked against 0307.99. Another major area of confusion is 1605.59, which covers prepared or preserved molluscs. If the molluscs are prepared in a sauce, heavily seasoned, or canned, they belong in Chapter 16 rather than Chapter 3.

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).
