Last updated: August 2026 dataNorway and Iceland are the leading sources of frozen whole mackerel entering the US under HTS 0303540000, which covers Scomber scombrus, S. australasicus, and S. japonicus in frozen, non-fillet form. The code is a single 10-digit provision with no further US subdivisions, so species, size grade, and processing style are captured in commercial documentation rather than in the tariff schedule itself.

No — 0303540000 is a single basket line covering all three Scomber species. The distinction matters commercially (different size profiles and fat content) and should be documented on invoices for FDA and CBP purposes, but it does not create separate duty treatment within this code.
When a shipment contains more than one Scomber species, classification typically follows the predominant species by weight. Consult a licensed customs broker if the species mix is close to equal or if the species identity is uncertain, as misclassification can trigger FDA examination or CBP penalties.
