Subheading 28 of 28 in heading 0307
Non-frozen stromboid conchs not elsewhere specified — covering live, fresh, chilled, dried, salted, and brined forms outside the frozen heading — are classified under tariff line 0307880000. Nicaragua is the primary US supplier, with Vietnam also a notable source, an unusual pairing that reflects both Caribbean wild-harvest operations and Indo-Pacific aquaculture or processing channels. Queen conch (Strombus gigas) in any non-frozen preserved state still triggers CITES Appendix II export-permit requirements, and FDA seafood HACCP rules apply regardless of preservation method.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Tariff line 0307880000 covers stromboid conchs that are live, fresh, chilled, dried, salted, or in brine — essentially all non-frozen commercial forms. Frozen stromboid conchs are classified separately under 030784 (0307840000). Importers should confirm the product's temperature and preservation state at the time of entry to select the correct heading.
Yes. CITES Appendix II controls apply to all commercial trade in queen conch (Strombus gigas) regardless of the form — live, fresh, frozen, dried, or salted. A valid CITES export permit from the country of origin is required for every commercial shipment, and US Fish & Wildlife Service enforces this at the port of entry.
