HS Code 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
HS code 0307.99 is the 6-digit subheading for 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. It is used for dried whelk, salted razor clams, smoked cockles, periwinkles in brine and dried sea snails.
What HS 0307.99 covers
This 'not elsewhere specified' category covers a diverse range of molluscs that have undergone traditional preservation methods such as drying, salting, brining, or smoking, excluding those specifically itemized in other 0307 subheadings. These methods significantly extend shelf life, reduce weight, and often enhance flavor, making them suitable for long-distance trade and storage without refrigeration. Such products are particularly popular in regions where these preservation techniques are part of culinary tradition or where fresh seafood access is limited. They cater to specific cultural tastes and provide a stable food source. Importers often include countries with strong culinary traditions for preserved seafood or large diaspora communities, such as East Asian nations and parts of Europe. Exporters are typically coastal nations with abundant mollusc resources and established processing capabilities for these traditional products, contributing to a global market for specialty preserved seafood.

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).
