Frozen Herring Fillets

Atlantic herring (Clupea harengus) and Pacific herring (Clupea pallasii) fillets, frozen, serve dual roles as a retail seafood product and a key input for fish processing, smoking, and marinating industries. Iceland and Norway dominate US supply, reflecting the North Atlantic's status as the world's primary herring fishery; both countries operate under robust quota management systems that can create seasonal supply tightening. The single 10-digit line 0304860000 covers all frozen herring fillets, so classification is straightforward, but importers should confirm country-of-origin documentation carefully given the multiple North Atlantic flag states involved. FDA prior notice is required for all seafood imports; consult a licensed customs broker or FDA-registered importer of record.
