Classification of salted molluscs under HS 0307.99
Salted molluscs are classified under HS code 0307.99 when they do not fall into the more specific categories defined in the preceding subheadings of heading 0307. Heading 0307 covers molluscs, whether in shell or not, and includes various states such as live, fresh, chilled, frozen, dried, salted, or in brine. Subheading 0307.99 serves as a residual category for "other" molluscs that are dried, salted, in brine, or smoked. This classification is used for species that are not explicitly named in subheadings 0307.11 through 0307.89, such as certain types of sea snails, whelks, or abalone. The classification process involves identifying the species and then determining the state of preservation. If the mollusc is salted and does not have a dedicated subheading (like oysters, mussels, or octopus do), it defaults to 0307.99. It is essential that the product has not been prepared or preserved by methods beyond those specified in Chapter 3. For instance, if the molluscs are cooked in a sauce, breaded, or hermetically sealed in a can with preservatives other than salt, they would shift to Chapter 16. This subheading ensures that all mollusc species not otherwise specified are captured under a single administrative code for international trade.

Codes often confused with 0307.99
Common mistake. Common misclassifications occur with 0307.91, which is for live, fresh, or chilled "other" molluscs, and 0307.92 for frozen versions. More importantly, if the molluscs are prepared or preserved beyond simple salting (e.g., canned in oil or vinegar), they must be classified under 1605.59. Confusion also arises with 0308.19 for salted sea cucumbers, which are not 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).
