Fresh or Chilled Jack & Horse Mackerel

The US HTS subdivides Trachurus spp. based on whether scaled fish weigh less than 6.8 kg (approximately 15 lbs), with line 0302451100 covering that smaller-size category and 0302455000 covering other forms not elsewhere specified. This size threshold affects duty classification, so importers must document individual fish or lot weights accurately on entry paperwork.

For HTS classification purposes, both 'horse mackerel' and 'jack mackerel' refer to Trachurus spp. and fall under heading 030245. However, trade professionals should confirm the scientific species name, as some regional 'jack' species may belong to the Carangidae family more broadly and could be classified differently. Consult a licensed customs broker if species identity is uncertain.
