Frozen Jack & Horse Mackerel (Trachurus Species)

Horse mackerel (Trachurus spp.) classifies under 030355/0303550000, while true mackerel (Scomber spp.) falls under 030354/0303540000. Because both are commonly called 'mackerel' in trade, invoices that omit the scientific name or use only a vernacular name can lead to misclassification. Customs brokers recommend that all documentation specify the Latin genus and species to avoid delays or reclassification.

As of current schedules, this heading does not carry widely publicized antidumping or Section 301 measures, but duty exposure can shift. Importers should verify the current tariff treatment with a licensed customs broker before shipment, particularly for origins such as Vietnam or China if product is transshipped through listed suppliers.
