Frozen Sole (Whole, Not Fillets or Roe)

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.
