Importers must ensure foreign processors operate under a seafood HACCP plan that meets FDA's 21 CFR Part 123 requirements. FDA may detain shipments from facilities with prior violations, and all labels must comply with US nutrition labeling and country-of-origin rules. Consulting a licensed customs broker or FDA-registered importer of record is advisable given the complexity of admissibility review.

Several prepared seafood products — including certain shrimp and crawfish preparations — are subject to active antidumping duty orders. The applicable order depends on the specific species, processing level, and country of origin, so precise HTS classification and scope review are essential before entry to avoid unexpected duty liability.
