Jack and horse mackerel belong to the family Carangidae (genus Trachurus), while true mackerel are Scombridae (genus Scomber). The HS system places them in separate 6-digit headings — 030355 versus 030354 — because they are biologically and commercially distinct species with different market applications, fat profiles, and fishery management regimes.
Commercial invoices and packing lists should state the scientific name (e.g., Trachurus murphyi for Chilean jack mackerel or Trachurus trachurus for Atlantic horse mackerel), the catch area, and the processing establishment's FDA registration number. Species-level documentation helps avoid reclassification disputes and supports FDA HACCP traceability requirements.
