What HS 0307.71 covers

This code encompasses live, fresh, or chilled clams, cockles, and ark shells, covering a broad spectrum of bivalve species highly sought after in global seafood markets. These products are inherently perishable, necessitating extremely rapid transport and stringent temperature controls to maintain their freshness and ensure food safety from harvest to consumer. Major importers are typically nations with high demand for fresh seafood, including those in East Asia, North America, and Europe, where these molluscs are enjoyed in both restaurants and homes. Exporters are often coastal countries boasting robust aquaculture industries or sustainably managed wild fisheries. Critical trade considerations include obtaining necessary health certifications, ensuring origin traceability, and utilizing specialized packaging that allows the molluscs to remain alive and fresh throughout transit.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
