About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS classification covers specific additives designed to enhance the performance and properties of mineral oils and similar liquids. Specifically, it falls under "Antiknock preparations: Based on lead compounds." These preparations are crucial for improving the octane rating of gasoline and preventing engine knocking, a detrimental phenomenon that can damage internal combustion engines. The "lead compounds" basis signifies that the primary active ingredient in these preparations is a lead-based chemical additive.

While the parent category addresses various prepared additives for mineral oils, this subcategory narrows the focus to antiknock preparations that specifically utilize lead compounds as their active component. It is important to distinguish this from other forms of antiknock preparations, such as those based on other metallic compounds or organic additives that might achieve similar octane-boosting effects without relying on lead.

As this node is a leaf node, there are no further subdivisions within HTS 3811.11.50.00. Therefore, the classification directly applies to any antiknock preparation based on lead compounds that does not fit into the more specific sibling category (3811.11.10.00, which covers preparations based on tetraethyl lead or mixtures thereof). This means that any lead-based antiknock preparation not explicitly defined by its tetraethyl lead content would fall under this residual "Other" classification within the lead-based antiknock preparations.
