Frozen Trout (Whole, Not Fillets or Roe)

Yes — the heading explicitly covers Oncorhynchus mykiss (rainbow trout) along with Salmo trutta (brown trout), O. clarki (cutthroat), O. aguabonita (golden), O. gilae (Gila), O. apache (Apache), and O. chrysogaster (Mexican golden). Both farmed and wild-caught specimens qualify, provided they are frozen and presented as whole fish rather than fillets, livers, or roes.

FDA requires a Prior Notice of Imported Food for all seafood shipments. For farmed trout, importers should also be prepared to provide aquaculture drug-use declarations and, where applicable, country-of-origin labeling (COOL) documentation. Shipments may be subject to FDA detention if residue violations have been flagged for a given supplier or country. Consulting a licensed customs broker and reviewing FDA's OASIS system for any existing import alerts on the source country is strongly advised.
