Yes. HTS 0303540000 is a single basket provision covering Scomber scombrus (Atlantic mackerel), Scomber australasicus (blue mackerel), and Scomber japonicus (chub mackerel) when frozen and not presented as fillets, livers, or roe. Importers should note that species identification may be requested by CBP or FDA, so commercial invoices and packing lists should specify the scientific name.
Frozen mackerel must be maintained at or below 0°F (-18°C) throughout transit and must carry country-of-origin labeling (COOL) at retail. FDA prior notice is required before arrival, and the foreign processing facility must be registered with FDA and operate under a documented seafood HACCP plan.
