Last updated: April 2026 dataFlatfish fillets — covering sole (0304430010), plaice (0304430015), flounder (0304430020), Greenland turbot (0304430025), and other flatfish (0304430090) — are sourced primarily from Canada, Spain, and Iceland, reflecting the North Atlantic's dominance in commercial flatfish fisheries. The species-specific breakdown at the 10-digit level means that correct identification of the flatfish variety is essential: sole, plaice, flounder, and turbot each carry their own line, with a catch-all for remaining flatfish. FDA prior notice and seafood HACCP documentation are required at entry, and importers should confirm that the common name on commercial invoices corresponds to the correct scientific species, as regional naming conventions for flatfish vary widely and can cause classification errors.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Regional common names for flatfish are notoriously inconsistent — 'sole' in Europe may refer to Dover sole (Solea solea) or any of several other species, and 'flounder' covers multiple genera. Importers should require the scientific name on the commercial invoice and packing list. If the species cannot be confirmed, the NESOI line 0304430090 may apply, but a CBP binding ruling is advisable for recurring shipments to lock in the correct classification.
No. Greenland turbot (Reinhardtius hippoglossoides) has its own dedicated tariff line, 0304430025, and is a distinct species from Atlantic turbot (Scophthalmus maximus). Atlantic turbot fillets would fall under the NESOI flatfish line 0304430090 if no other specific line applies. The distinction matters because the two species differ in origin, price, and market positioning.
