Vietnam and China together account for the largest share of US imports in this heading, which spans a notably granular set of eight 10-digit tariff lines reflecting the commercial diversity of bivalve preparations. The schedule distinguishes razor clams in airtight containers (1605561000), whole or chopped boiled clams in packages not exceeding 680 grams gross weight (1605561500), clams in airtight containers not elsewhere specified (1605562000), and general clam preparations (1605563000), alongside separate lines for cockles and arkshells (1605566000) and products containing fish meat (1605560500). Correct classification depends on species, container type, and net weight, making careful product review essential. FDA admissibility review applies; importers should confirm that foreign processing establishments are FDA-registered and that country-of-origin labeling is compliant.

Frequently Asked Questions

What factors determine which 10-digit HTS line applies to an imported clam product?

Classification depends on three main variables: species (razor clams vs. other clams vs. cockles/arkshells), container type (airtight vs. non-airtight), and package weight (the 680-gram gross weight threshold is relevant for boiled whole or chopped clams). Importers should review all three factors before filing entry.

Who are the primary foreign sources of prepared clams, cockles, and arkshells entering the US?

Vietnam and China lead supply under this heading, followed by Indonesia, Thailand, and South Korea. The mix of species and processing formats varies by country, so origin can be a useful indicator of likely product type.
