Last updated: April 2026 dataFlounder, sole, halibut, plaice, and related flatfish species enter US commerce in frozen whole or dressed form under this heading, distinct from fillets which are classified separately. FDA exercises admissibility oversight at the port of entry, and importers must ensure compliance with seafood HACCP regulations. Species-level identification is a recurring classification challenge, as different flatfish species may carry different duty rates at the HTS 10-digit level.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Frozen flat fish under this heading are whole, gutted, or dressed fish — not separated into fillets. Once the flesh is removed from the bone and presented as fillets, the product shifts to the fish fillets heading. Species identification documents and processing records help customs officers confirm the correct classification.
FDA has jurisdiction over imported seafood and requires importers to have a HACCP plan in place and to verify that foreign suppliers meet US food safety standards. Shipments may be subject to FDA examination at the port of entry. Consulting a licensed customs broker familiar with seafood imports is advisable given the complexity of admissibility review.
