Last updated: April 2026 dataScombrid mackerel — including Atlantic mackerel, Pacific mackerel, and chub mackerel — are widely traded frozen for both retail consumption and industrial processing into canned products and fishmeal. Species-level identification within the Scombridae family is important for accurate classification, as some scombrids (such as king mackerel) may be subject to FDA import alerts related to elevated mercury levels. Importers should maintain species documentation and be prepared for FDA sampling at entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Certain large scombrid species, particularly king mackerel, carry elevated methylmercury levels and are subject to FDA consumption advisories. FDA may also sample frozen mackerel shipments for histamine (scombroid toxin), which can accumulate if cold-chain integrity is compromised during harvest or transit. Importers should ensure temperature logs and HACCP documentation are available for review.
The Scombridae family includes Atlantic mackerel, Pacific (chub) mackerel, king mackerel, and Spanish mackerel, among others. Species identity affects FDA labeling compliance, mercury advisory applicability, and in some cases duty rates at the HTS 10-digit level. Supplier-provided species certificates and scientific names on commercial invoices help prevent classification disputes and labeling violations.
