Last updated: August 2026 dataSouthern bluefin tuna (Thunnus maccoyii) is one of the most quota-constrained fish in global trade, managed exclusively by the Commission for the Conservation of Southern Bluefin Tuna (CCSBT), which allocates national catch limits among a small group of member countries. Japan leads US supply under this heading, followed by Indonesia and Morocco — a supplier mix that reflects both the species' Southern Ocean range and the distribution of CCSBT national allocations. The sole US tariff line is 0303460000, and NOAA's SIMP requires full harvest traceability documentation at entry. Given the species' critically endangered status and the strict quota regime, importers face heightened scrutiny on catch documentation authenticity.

Importers must provide a CCSBT Catch Documentation Scheme (CDS) certificate demonstrating the fish was harvested within the exporting country's CCSBT national allocation. NOAA's SIMP additionally requires harvest event data submitted through the ACE filing system. Shipments without valid CDS documentation are subject to detention or refusal.
Japan holds one of the largest CCSBT national allocations and has long-established supply chains for premium sashimi-grade tuna, including cold-chain infrastructure and buyer relationships with US high-end seafood distributors. Japan also re-exports southern bluefin sourced from other CCSBT member nations, consolidating trade flows through Japanese trading houses.
