HS Code 0307.91 – Molluscs; n.e.c. in heading 0307, whether in shell or not, live or fresh, chilled
HS code 0307.91 is the 6-digit subheading for molluscs, n.e.c. in heading 0307, whether in shell or not, live or fresh, chilled. It is used for live sea snails, fresh whelks, chilled razor clams, live cockles and fresh periwinkles.
What HS 0307.91 covers
This 'not elsewhere specified' category for live, fresh, or chilled molluscs covers a wide array of species beyond those specifically listed in other 0307 subheadings, such as oysters, scallops, mussels, cuttlefish, squid, octopus, abalone, and conch. It encompasses lesser-known or regionally popular molluscs traded in their most natural, perishable state. International trade in these goods often involves specialized logistics for rapid transport to maintain freshness, catering to niche markets, ethnic cuisines, or high-end restaurants. The demand for live or fresh products signifies a market willing to pay a premium for quality and immediate consumption. Importers are typically countries with strong seafood consumption cultures or large diaspora communities, such as Japan, South Korea, and various EU nations. Exporters are coastal nations with diverse mollusc fisheries and efficient cold chain infrastructure, ensuring the swift delivery of these delicate products.

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).
