Product classification
HS code for Fresh oysters: 0307.11
Molluscs, oysters, whether in shell or not, live, fresh or chilled.
Classification of fresh oysters under HS 0307.11
Fresh oysters are classified under HS code 0307.11. Chapter 3 of the Harmonized System covers fish and crustaceans, molluscs, and other aquatic invertebrates. Heading 0307 specifically addresses molluscs, whether in shell or not, live, fresh, chilled, frozen, dried, salted, or in brine. The subheading 0307.11 is the most specific classification for oysters that are live, fresh, or chilled. This classification is based on the biological nature of the product and the minimal level of processing it has undergone. Under GRI 1, the product is classified here because it is a raw mollusc in its natural or chilled state. If the oysters were to undergo further processing, such as steaming or boiling, they would move out of Chapter 3 and into Chapter 16, which covers prepared or preserved seafood.

Codes often confused with 0307.11
Common mistake. A common misclassification occurs with HS code 0307.12, which is used for frozen oysters. Importers often confuse these when the product is transported at very low temperatures that may lead to partial freezing. Additionally, HS code 0307.19 is used for dried, salted, or smoked oysters. Most importantly, prepared oysters (e.g., canned in oil or breaded) must be classified under HS code 1605.51, as Chapter 3 only covers raw or minimally processed aquatic invertebrates.

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).
