Clams, Cockles, and Ark Shells, Live, Fresh, or Chilled

Geoduck (Panopea generosa) is classified separately under 0307710050 because of its distinct commercial value, size, and trade patterns — particularly its role as a high-value export commodity to Asian markets. The separation allows customs authorities to track trade flows for this species independently from commodity clams.

FDA administers the National Shellfish Sanitation Program (NSSP), which requires that live bivalve mollusks originate from a country whose shellfish control authority has an equivalence agreement with the US. Shipments must be accompanied by shellfish tags or certificates from the approved foreign authority. Importers should verify their source country's current NSSP status before shipment.
