HS code for Frozen mussels: 0307.32
Molluscs, mussels (Mytilus spp., Perna spp.), whether in shell or not, frozen.
Classification of frozen mussels under HS 0307.32
Frozen mussels are classified under HS code 030732. This classification is specific to mussels belonging to the genera Mytilus and Perna. Under the Harmonized System, heading 0307 covers molluscs, whether in shell or not, live, fresh, chilled, frozen, dried, salted, or in brine. Subheading 030732 is specifically reserved for the frozen state. This includes mussels that are frozen whole in their shells, those on the half-shell, and mussel meat that has been removed from the shell before freezing. The classification is straightforward but requires that the product has not been prepared or preserved beyond simple freezing. If the mussels are steamed or boiled and then frozen, they may still fall under this heading provided they are in shell, but deshelled and cooked mussels generally move to Chapter 16. This code is vital for tracking the trade of popular species like the Blue mussel and the Green-lipped mussel.

Codes often confused with 0307.32
Common mistake. Mussels are frequently misclassified under HS code 030731, which is for live, fresh, or chilled mussels. Another common error is using 160553, which is for prepared or preserved mussels (e.g., those in airtight containers, marinated, or fully cooked and deshelled). It is also important not to confuse them with other bivalves like clams or cockles, which fall under 030772 when frozen.

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).
