U.S. imports of frozen sole (whole, not fillets or roe) (HS 030333) totaled $2.8M in April 2026, traded with 7 countries.
Sole of the genus Solea — most notably Dover sole (Solea solea), a premium European flatfish — enters the US under tariff line 0303330000 as whole frozen fish, distinct from sole fillets which classify separately. The Netherlands leads US supply, followed by Iceland, Canada, and the United Kingdom, a pattern that reflects both North Sea trawl fisheries and the species' commercial importance in European cuisine. Dover sole commands premium pricing in fine-dining and specialty retail channels, and supply is sensitive to EU quota decisions under the Common Fisheries Policy. FDA admissibility review applies; consult a licensed customs broker regarding documentation for European-origin seafood.

Heading 030333 covers only fish of the genus Solea — true soles, including Dover sole (Solea solea). Fish marketed in the US as 'Pacific Dover sole' (Microstomus pacificus) or 'lemon sole' may belong to different flatfish genera and would classify under different HTS headings. Importers and brokers should verify the scientific name on the exporter's documentation to ensure correct classification, as misidentification can result in reclassification and duty adjustments.
Sole (Solea solea) in the North Sea is managed under annual Total Allowable Catches set through the EU Common Fisheries Policy, with the UK now negotiating its share bilaterally post-Brexit. When TACs are cut in response to stock assessments, Dutch and UK export volumes decline, which can reduce US availability and push up prices for frozen whole sole. Importers should track annual EU-UK fisheries negotiations, typically concluded in December, to anticipate supply conditions for the following year.
