FDA governs admissibility, and shellfish imports are additionally subject to the National Shellfish Sanitation Program (NSSP) framework, which requires that product originate from approved growing areas certified by the exporting country's competent authority. Importers should confirm that the country of harvest holds a current NSSP memorandum of understanding with FDA.

Importers should verify that the country of harvest (which may differ from the country of processing) is on FDA's current list of approved shellfish-exporting nations before sourcing.
