Last updated: August 2026 dataFlatfish fillets — spanning sole, plaice, flounder, Greenland turbot, and other species — enter the US under a heading with six distinct 10-digit lines that require species-level identification at classification. Canada leads supply, reflecting the proximity of North Atlantic and Pacific flatfish fisheries, with Spain and Iceland also significant sources. Imports from China are subject to Section 301 tariff considerations, making origin documentation a key cost variable for buyers sourcing across multiple suppliers. FDA Prior Notice and registered-establishment requirements apply to all entries. Consult a licensed customs broker for current admissibility and classification requirements.

85 import shipments a month
The US schedule breaks out sole (0304430010), plaice (0304430015), flounder (0304430020), Greenland turbot (0304430025), a legacy aggregate line (0304430000), and a residual NESOI line (0304430090). Misclassifying a species — for example, entering a Dover sole fillet as a generic flatfish — can result in CBP penalties and may affect applicable duty rates. Commercial invoices and catch certificates should identify the species by common and scientific name.
Greenland turbot (Reinhardtius hippoglossoides), also known as Greenland halibut, is a deep-water flatfish distinct from European turbot (Scophthalmus maximus). It has its own dedicated line (0304430025) in the US schedule, whereas European turbot fillets would fall under the NESOI line (0304430090). Importers should confirm species identity with the exporter to avoid misclassification between these lines.
