Frozen Atlantic Salmon and Danube Salmon

Danube salmon (huchen) is a rare, CITES-listed species with very limited commercial aquaculture production; it appears in the heading's legal text but represents a negligible share of actual US import volume. Any shipment of Danube salmon would require CITES documentation in addition to standard SIMP and FDA requirements, making it a highly specialized import.

This heading covers frozen Atlantic salmon in whole, headed, gutted, or otherwise dressed forms — provided the fish has not been reduced to separated flesh portions. Once the flesh is separated from the backbone into fillet form, the product moves to the frozen fish fillet headings in Chapter 3. Butterfly-cut or pin-bone-in product that retains the backbone generally remains in this heading, but borderline presentations should be reviewed with a licensed customs broker.
