Chinook (king), sockeye (red), coho (silver), pink, and chum salmon are the primary Pacific species covered here. Species is typically documented on the commercial invoice and health certificate using both common and scientific names; FSIS may verify species identification during reinspection, particularly for high-value species like chinook.

Most Pacific salmon runs are concentrated in summer and early fall, creating a narrow window for fresh product. Importers sourcing fresh non-Atlantic salmon must coordinate closely with processors on harvest timing, as the fresh/chilled shelf life is short and air-freight capacity can tighten sharply during peak season.
