Last updated: August 2026 dataA broad residual heading, this category captures molluscs and aquatic invertebrates not enumerated elsewhere — including sea cucumbers, sea urchins, jellyfish, and their processed derivatives — across all preservation states from fresh to dried. FDA admissibility review applies to all forms, and the edible flour and meal subset must be documented as fit for human consumption to avoid reclassification into non-food categories. The wide species range within this heading makes accurate scientific and common-name identification on commercial invoices essential for both classification and potential CITES compliance checks.

Sea cucumbers (bêche-de-mer), sea urchins (uni), jellyfish, and various whelks and periwinkles are among the most commercially significant species in this catch-all heading. Many of these are high-value specialty seafood items with strong demand in Asian markets, and their dried or salted forms are particularly common in international trade.
Yes. Certain sea cucumber and giant clam species are listed under CITES appendices, requiring export permits from the country of origin and import documentation demonstrating legal acquisition. Importers should verify the CITES status of the specific species before shipment, as non-compliance can result in seizure and penalties at the port of entry.
