Frozen Sardines, Sardinella, Brisling & Sprats

Frozen small pelagics classified here span three distinct genera — Sardina/Sardinops (true sardines), Sardinella, and Sprattus sprattus (brisling/sprats) — each with different fat profiles and end-use markets ranging from direct retail to fishmeal and canning feedstock. All whole frozen fish under this heading enter under a single US tariff line (0303530000), covering the product except fillets, livers, and roes. Mexico leads US supply, with Portugal and Morocco also significant sources, reflecting both Atlantic sardine fisheries and established processing infrastructure. FDA oversight applies at entry, and importers should verify that country-of-origin labeling and seafood HACCP documentation are in order before shipment.
