Last updated: August 2026 dataFlounder frozen in whole or dressed form — excluding fillets, livers, and roes — is classified at this 10-digit line when the species does not fall under a more specific provision such as rock sole or yellowfin sole. The NESOI qualifier means importers must confirm that the flounder species in question lacks its own dedicated HTS line before using this code, making species-level supplier documentation essential. FDA prior notice and HACCP compliance apply; consult a licensed customs broker or FDA specialist for admissibility guidance.

Rock sole (Pleuronectes bilineatus) and yellowfin sole (Pleuronectes asper) each have their own dedicated 10-digit lines (0303390120 and 0303390130 respectively) and should not be entered here. Other flounder species — such as Pacific halibut-adjacent flatfish or species without a named US tariff provision — fall into this NESOI line, provided they are not turbot or sole (Solea spp.), which have separate headings.
Yes, but importers planning to process and re-export should consider whether a bonded warehouse or foreign-trade zone entry is more advantageous, as duties paid on import may not be recoverable unless a drawback claim is filed. The specific processing operation and destination market will determine the optimal customs strategy.
