Last updated: April 2026 dataFlatfish species not covered by the dedicated sole, turbot, or halibut subheadings — including flounder and miscellaneous flatfish — are classified here, with the US schedule separating flounder (0302290110) from other flatfish not elsewhere specified (0302290190). South Korea is the leading supplier, reflecting significant Korean fisheries and aquaculture production of species such as olive flounder (hirame), which is widely consumed in sashimi markets. Mexico and Canada also contribute supply, particularly for Pacific-caught species. FDA Prior Notice and Seafood HACCP documentation are required for all fresh fish imports.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Olive flounder (Paralichthys olivaceus) is a true flounder and should be classified under 0302290110. Importers should include the scientific name on entry documents to support this classification, as CBP may request species verification for high-value sashimi-grade fish where misclassification risk is elevated.
The flounder line captures species clearly identified as flounder by scientific classification, while the NESOI line covers other flatfish — such as plaice, dab, or witch flounder — that do not fit the more specific provisions for sole, turbot, halibut, or flounder. When a species' common name is ambiguous, importers should rely on scientific nomenclature and, if uncertain, seek a binding ruling from CBP before importation.
