U.S. imports of frozen clams (HS 030772) totaled $1.5M in August 2026, imported from 8 countries.
Importers of Frozen Clams paid $38K in duties in August 2026, an effective tariff rate of 2.59% of the $1.5M imported — duty actually collected as a share of that value, not the published tariff schedule. Frozen Clams imports of $1.5M in August 2026 ran 24% above the year-to-date monthly average of $1.2M.
Last updated: August 2026 dataFrozen clams serve a broad range of end uses — from restaurant chowder bases to retail seafood blends — making this a commercially active heading with diverse supplier geography. Canada leads US imports, supplying surf clams and other Atlantic species, while Vietnam has grown significantly as a source of frozen clam meat for food-manufacturing applications. The US schedule distinguishes geoduck clams (0307720030), other clams excluding geoduck and Stimson's clams (0307720055), a transitional 'other' clam line (0307720050), and frozen cockles and ark shells (0307720060), so importers must identify both species and product form to select the correct 10-digit line. FDA seafood HACCP requirements apply, and frozen clam products from certain origins have been subject to FDA import alerts; supplier qualification and third-party audit documentation are standard risk-management tools for this category.

Both lines cover frozen clams other than geoduck, but 0307720055 specifically excludes both geoduck and Stimson's clams, while 0307720050 is a broader 'other' line. In practice, importers should determine whether their product is geoduck (0307720030), Stimson's clam, or another species, and classify accordingly. When the species is ambiguous or a new variety, a binding ruling from CBP provides the most reliable guidance.
Freezing alone is not a substantial transformation, so clam meat frozen in a country different from where the clams were harvested generally retains the harvest country as its country of origin. However, if the clam meat undergoes further processing — such as cooking, mincing, or incorporation into a prepared product — a substantial transformation analysis may shift the origin. Importers sourcing from complex supply chains should seek a CBP binding ruling to confirm origin before entry.
