Last updated: April 2026 dataFrozen abalone, dried scallops, salted clams, brined mussels, and processed flours and meals of non-crustacean aquatic invertebrates all converge in this residual heading, which explicitly excludes crustaceans classified elsewhere. Dried scallops (conpoy) and dried abalone are among the highest unit-value items in this heading, with strong demand in East Asian culinary markets. FDA admissibility and HACCP verification apply across all preservation states, and bivalve species remain subject to NSSP-equivalent harvest-area certification requirements regardless of whether they arrive frozen or dried.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. FDA's position is that bivalve molluscs — including clams, mussels, scallops, and abalone — require traceability to an approved harvest area regardless of preservation state. The NSSP framework applies to fresh, frozen, and processed bivalves intended for human consumption. Importers should obtain harvest-area certification documentation from the foreign shipper and retain it as part of their HACCP importer verification records.
Conpoy is the dried adductor muscle of scallops, a labor-intensive product with a concentrated umami flavor prized in Chinese cuisine. For classification, the key distinction is that it is dried (not frozen or fresh), which places it in this heading rather than a fresh/chilled or frozen scallop category. High unit values mean that accurate weight and value documentation is important to avoid undervaluation scrutiny at entry.
