Classification of smoked ark shells under HS 0307.79
Smoked ark shells are classified under HS code 0307.79. This subheading is part of the broader category for clams, cockles, and ark shells belonging to the families Arcidae, Arcticidae, and others. The Harmonized System organizes molluscs in Chapter 3 based on their species and the level of processing they have undergone. Heading 0307 includes molluscs that are dried, salted, in brine, or smoked. Because ark shells are bivalve molluscs belonging to the Arcidae family, they are grouped with clams and cockles. The code 0307.79 specifically captures those that are not live, fresh, chilled, or frozen, but rather preserved through smoking or drying. This classification applies to the meat whether it is presented in the shell or has been shucked, provided that the smoking process is the primary method of preservation and no additional culinary preparation has moved the product into the prepared or preserved category of Chapter 16.

Codes often confused with 0307.79
Common mistake. Smoked ark shells are often misclassified under 1605.56, which is the code for prepared or preserved clams, cockles, and ark shells. The distinction lies in the extent of processing; if the shells are part of a prepared dish or preserved in a way not mentioned in Chapter 3 (like vinegar or airtight cans with sauce), they move to 1605. They are also sometimes confused with 0307.71, which is only for live, fresh, or chilled specimens.

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).
