HS code for Chilled mussels: 0307.31
Molluscs, mussels (Mytilus spp., Perna spp.), whether in shell or not, live, fresh or chilled.
Classification of chilled mussels under HS 0307.31
Mussels belonging to the genera Mytilus and Perna are classified under HS code 0307.31 when they are live, fresh, or chilled. This classification is part of Heading 0307, which covers molluscs. The subheading 0307.31 is specific to these two genera, which include the common blue mussel and the green-lipped mussel. The classification applies whether the mussels are presented in their shells or have been shucked. The "fresh or chilled" designation is critical; it refers to products that are either alive or have been kept at a temperature just above freezing to maintain freshness during transport and sale. This code excludes mussels that have been frozen (0307.32) or those that have been prepared or preserved, such as those canned in brine or vinegar, which would move to Chapter 16. Proper classification depends on verifying the genus and ensuring the preservation method does not exceed chilling. Mussels are often traded live in mesh bags or chilled on ice. For customs purposes, the distinction between species is less important than the genus and the state of the product. This code is also used to monitor health certifications required for bivalve molluscs in many jurisdictions, ensuring they originate from approved harvesting waters.

Codes often confused with 0307.31
Common mistake. Mussels are frequently misclassified under 0307.32 if they are frozen, or 0307.39 if they are dried, salted, or smoked. Another common error is using 1605.53, which is for prepared or preserved mussels (e.g., those in airtight containers or marinated). Importers must also distinguish between the genera Mytilus/Perna and other bivalves like clams (0307.71) or scallops (0307.21), which have different subheadings. Misidentifying the genus can lead to incorrect duty applications.

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).
