Frozen Salmonidae (Other), Whole — Not Elsewhere Specified

Classification follows the species hierarchy in Chapter 3. Named species — Atlantic salmon (030311), sockeye and other Pacific salmon (030312–030313), and the seven trout species in 030314 — take priority. If the salmonid species is not enumerated in those specific headings, it falls to 030319 as NESOI. Importers should obtain a species identification certificate from the exporter and, when uncertain, seek a binding ruling from CBP before shipment.

Duty rates can differ across the named and NESOI salmonid headings, so correct species identification has direct cost implications. Because rates are subject to change and vary by tariff line, importers should verify the current rate in the USITC Harmonized Tariff Schedule and consult a licensed customs broker to confirm classification and applicable duty treatment before entry.
