Flatfish species not covered by the named headings for halibut, plaice, sole, or turbot — most notably flounder — are classified here, with the US schedule separating flounder (0302290110) from other residual flatfish (0302290190). Mexico and South Korea are the leading US suppliers under this heading, followed by Canada, Japan, and Portugal, reflecting a diverse mix of Pacific and Atlantic species. Section 301 tariffs may affect imports from certain origins depending on the specific tariff line and country of origin, so importers should verify current trade-remedy applicability. FDA prior notice is required for all fresh fish entries, and species-level documentation is important to confirm that the product does not belong in a more specific named heading.
