381190

Oxidation and gum inhibitors, viscosity improvers, anti-corrosive preparations, other prepared additives for mineral oils or liquids used as mineral oils (including gasoline), n.e.c. in heading no. 3811

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 381190 when importing or exporting prepared additives like oxidation inhibitors for mineral oils, such as gasoline. For instance, if you're shipping a package of anti-corrosive additives designed for engine oils, this is the correct code.

This code specifically covers products that enhance the performance of mineral oils by preventing oxidation and gum formation. It differs from HS-6 381191, which focuses on anti-knock preparations, highlighting the importance of selecting the right classification based on the product's function.

If you're dealing with viscosity improvers or other prepared additives that aren't classified elsewhere, HS-6 381190 is your go-to. For example, a shipment of a liquid additive that improves fuel stability would fall under this code, while a fuel octane booster would require HS-6 381191.

Understanding the nuances between these codes is essential for compliance and accurate duty assessment. Make sure to verify the specific properties and intended use of your product to ensure proper classification.
