Last updated: April 2026 dataJack and horse mackerel of the genus Trachurus — including Chilean jack mackerel (Trachurus murphyi) and Atlantic horse mackerel (Trachurus trachurus) — are classified separately from true Scomber mackerels, consolidating into a single 10-digit line (0303550000). These species are important inputs for fishmeal and fish oil production as well as for canned and frozen consumer products in European, Latin American, and Asian markets. The Chilean jack mackerel fishery in the Southeast Pacific is one of the largest pelagic fisheries by volume globally, and supply availability is closely tied to stock assessments issued by the South Pacific Regional Fisheries Management Organisation (SPRFMO).
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Jack and horse mackerels (Trachurus spp.) classify under 0303550000, while true mackerels (Scomber spp.) classify under 0303540000. The two genera are sometimes sold under similar trade names in different markets, but they are distinct HTS lines. Misclassification can result in incorrect duty assessment and potential penalties; species-level documentation from the supplier is the standard safeguard.
The South Pacific Regional Fisheries Management Organisation sets annual catch limits for Chilean jack mackerel (Trachurus murphyi), the dominant species in this heading by volume. When SPRFMO reduces the total allowable catch in response to stock assessments, available frozen supply can tighten significantly mid-year. Importers with forward contracts should monitor SPRFMO annual meeting outcomes, typically published in the first quarter, to anticipate supply constraints.
