Fish Fillets, Fresh or Chilled, NESOI

Serving as the catch-all heading for fresh and chilled fish fillets not classified elsewhere, this heading spans a wide range of species — from freshwater pickerel and whitefish (0304490106, 0304490109) to tilapia (0304490112), Atlantic Ocean perch (0304490120), and cusk (0304490125) — making precise species identification on commercial invoices essential to landing in the correct 10-digit line. Canada and Mexico are the dominant suppliers, benefiting from geographic proximity and integrated North American cold-chain logistics under USMCA. FDA Prior Notice is required for all fish fillet shipments, and country-of-origin labeling obligations apply at retail. The breadth of species covered means classification disputes are common, particularly for lesser-known saltwater species that may fall into the residual line 0304490190.
