Overview
This HTS category, 3811.11.10.00, specifically classifies antiknock preparations for mineral oils (including gasoline) that are formulated based on either tetraethyl lead or a mixture containing both tetraethyl lead and tetramethyl lead. These preparations are designed to increase the octane rating of gasoline and prevent engine knocking or pre-ignition by retarding combustion.
This classification is distinguished from its sibling category, 3811.11.50.00, which covers "Other" antiknock preparations. While both fall under the broader heading of lead-based antiknock compounds, this particular code is exclusively for those whose active antiknock agents are exclusively tetraethyl lead or a defined blend of tetraethyl and tetramethyl lead. The sibling category would encompass other lead-based antiknock agents not meeting this precise formulation requirement.
As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification hinges entirely on the presence and type of lead compounds as the primary antiknock agent. Importers must ensure that the composition of their goods precisely matches the specified lead compounds to correctly utilize this tariff code.
