Classification of frozen oysters under HS 0307.12
Frozen oysters are classified under HS code 0307.12. This code is part of Chapter 3, which encompasses fish, crustaceans, and other aquatic invertebrates. Heading 0307 specifically covers molluscs, whether in shell or not, and includes various states such as live, fresh, chilled, frozen, dried, or salted. The 0307.1x subheadings are dedicated to oysters. Within this group, 0307.11 is used for live, fresh, or chilled oysters, while 0307.12 is the specific code for those in a frozen state. This classification applies to all species of oysters and covers both whole oysters in their shells and shucked oyster meat. The essential requirement for this code is that the oysters have been frozen and have not undergone further preparation like smoking or canning.

Codes often confused with 0307.12
Common mistake. Oysters are frequently misclassified under 0307.11 if the importer does not distinguish between chilled and frozen states. More significantly, prepared or preserved oysters fall under HS code 1605.51. This includes oysters that have been smoked, canned, or preserved in airtight containers. If the oysters are breaded or battered and then frozen, they are considered a prepared meal and should be classified under heading 1605. Another potential error is 0307.19, which is a residual category for oysters in forms like dried or salted, but not 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).
