HSChapter 03
Whole frozen yellowfin tuna (Thunnus albacares, head-on and ungutted) is the presentation most commonly traded for sashimi-grade processing and high-end foodservice, where buyers want to assess freshness and fat content before butchering. This 10-digit line is distinguished from 0303420060 strictly by the whole, head-on condition of the fish at time of importation. Cold-chain integrity from vessel to US port is a key quality and compliance concern, as temperature abuse can trigger FDA refusal on histamine (scombrotoxin) grounds. Importers should ensure foreign processors maintain validated cold-chain records as part of their HACCP documentation.

Line 0303420020 applies only when the yellowfin tuna is frozen in its entirety — head-on and ungutted. Any processing step that removes the head, guts, or fins before freezing shifts the product to the NESOI line (0303420060). CBP may request documentation such as processing records or photographs to confirm the condition of the fish at time of export.
Histamine (scombrotoxin) formation is the principal hazard for frozen scombroid fish like yellowfin tuna. FDA's seafood HACCP regulations require importers and their foreign suppliers to have a HACCP plan with a critical control point addressing time-temperature control from catch through freezing. Shipments found to have temperature-abuse indicators or elevated histamine levels at port of entry are subject to detention and refusal of admission.
