381111

Anti-knock preparations; based on lead compounds

Heading 3811Anti-knock preparations, oxidation and gum inhibitors, viscosity improvers, anti-corrosive preparations and the like, for mineral oils (including gasoline) or other liquids used for the same purposes

Chapter 38: Miscellaneous chemical products

Plain-language overview

Use HS-6 381111 when importing or exporting anti-knock preparations based on lead compounds, commonly used in gasoline. For instance, a shipment of leaded gasoline additives falls under this code.

This code specifically covers anti-knock agents that enhance the performance of mineral oils and fuels. In contrast, HS-6 381112 applies to similar preparations but is based on compounds other than lead.

When dealing with products like tetraethyl lead, which is used to improve engine performance by preventing knocking, this HS-6 is the correct classification. It's essential to distinguish it from other additives that may not contain lead.

If you're unsure whether your product qualifies under this code, consider its formulation and intended use. Products designed for similar purposes but without lead may require a different classification.
