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, 3811.19.00.00, covers "Other" antiknock preparations for mineral oils and similar liquids. This residual category encompasses antiknock preparations that do not fit into the more specific sibling category 3811.11, which is exclusively for preparations based on lead compounds. Therefore, goods classified here would be designed to increase the octane rating of fuels like gasoline but would utilize non-lead based chemical compounds or formulations as their primary antiknock agent.

The purpose of these preparations is to prevent premature detonation (knocking) in internal combustion engines, thereby improving engine performance and efficiency. Examples of products that might fall under this classification include antiknock agents based on manganese, iron, or other metallic compounds, as well as organic compounds specifically formulated for this anti-knock function, provided they are not classified elsewhere.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification within 3811.19.00.00 hinges on the chemical composition of the antiknock preparation and its intended use in mineral oils or analogous liquids, specifically excluding those primarily reliant on lead compounds.
