FDA has jurisdiction over imported fish and fishery products. Shipments may be subject to FDA examination or automatic detention if prior compliance issues exist with the foreign establishment. USDA FSIS does not cover fish — its authority is limited to meat, poultry, and egg products.

The common name 'whitefish' is applied to several freshwater species across different genera. Classification here requires the fish to be freshwater, fresh or chilled, and not a fillet, liver, or roe. If a species has its own enumerated HTS line, that more specific provision takes precedence over this NESOI line. Species documentation is strongly recommended to support the classification decision.
