Fresh or Chilled Trout (Salmo trutta and Oncorhynchus spp.)

Farmed rainbow trout (Oncorhynchus mykiss) dominates commercial trade under this heading and is separated at the 10-digit level (0302110010) from all other fresh or chilled trout (0302110090), reflecting the aquaculture industry's importance in US import patterns. Norway is the leading supplier, leveraging its established cold-water salmonid farming infrastructure, with Canada and Colombia also significant sources. All fresh and chilled fish imports are subject to FDA oversight for food safety, and shipments from approved foreign establishments may also face USDA FSIS review if the product is processed in a way that triggers meat-inspection jurisdiction. Cold-chain integrity from harvest to US port of entry is a primary quality and compliance concern for buyers.
