Several sea cucumber species have been added to CITES appendices in recent years, particularly following increased commercial pressure on wild populations. Importers should verify the species name against current CITES listings and, if the species is listed, obtain the required export permit from the source country and an import permit from the US Fish and Wildlife Service before shipment arrives.

Whole sea urchins — live, fresh, chilled, or frozen — classify under 030821 or 030822. Processed sea urchin roe (uni) prepared for consumption may fall under 030829 if preserved by methods other than freezing, or could migrate to Chapter 16 if it qualifies as a prepared or preserved seafood product. The degree of processing and the form of the product at the time of importation determine the correct heading, so detailed product specifications are essential.
