Last updated: July 2026 dataFlatfish 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.

The US schedule carves out flounder as a named species group at 0302290110, while 0302290190 captures all other fresh or chilled flatfish not specifically enumerated. Importers should identify the species by scientific name on commercial documentation; if the species is a recognized flounder (family Pleuronectidae or Paralichthyidae), it belongs at 0302290110 rather than the NESOI line.
Section 301 tariffs target goods of Chinese origin and generally do not apply to imports from South Korea or Japan. However, importers sourcing flatfish from any origin should confirm the current trade-remedy landscape with a licensed customs broker, as tariff schedules and applicable measures can change. Country of origin must be accurately declared to ensure the correct duty treatment.
