Frozen Clams, Cockles, and Ark Shells

Frozen clam products — a staple ingredient in foodservice, canned-goods manufacturing, and Asian cuisine — are classified across four US tariff lines that separate geoduck (0307720030), Stimson's clams (implicitly carved out in 0307720055), other clams (0307720050 and 0307720055), and cockles and ark shells (0307720060). Canada leads supply, with Vietnam and China serving as major sources of processed frozen clam meat. Imports from China are subject to Section 301 tariffs, a cost factor that importers sourcing from that origin must account for in landed-cost calculations. FDA admissibility review applies to all frozen shellfish entries.
