0302.45.11.00 - Scaled (whether or not heads, viscera and/or fins have been removed, but not otherwise processed), in immediate containers weighing with their contents 6.8 kg or less

This HTS category covers jack and horse mackerel, scientifically identified as belonging to the genus *Trachurus spp.* These fish are classified as fresh or chilled, with the proviso that they have not undergone further processing beyond scaling. This includes fish where the heads, viscera, and/or fins may have been removed, but crucially, they must be presented in their immediate containers, with each container weighing 6.8 kg or less. This specific packaging and weight limitation are key criteria for classification within this sub-heading.

The primary distinction for this sub-heading lies in its specific focus on *Trachurus spp.* compared to its sibling category, 0302.45.50.00, which is designated for "Other." This implies that any jack and horse mackerel fitting the description of being scaled and presented in containers under 6.8 kg will be classified here, while other types of fish falling under the broader "Jack and horse mackerel" heading but not meeting these precise criteria would be directed to the "Other" sub-heading.

As this is a leaf node in the HTS classification system, there are no further subdivisions. Therefore, the classification of jack and horse mackerel under this code is definitive based on the described physical state (scaled, fresh or chilled) and packaging requirements (immediate containers weighing with their contents 6.8 kg or less). Any variations in processing beyond what is permitted, or different packaging configurations, would necessitate re-evaluation under other HTS codes.
