Clams, Cockles & Arkshells, Prepared or Preserved

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.
