Plain-language overview

Use HS-6 381900 when importing or exporting hydraulic fluids specifically designed for brake systems and other hydraulic applications. For example, if you’re shipping a container of brake fluid that contains less than 70% petroleum oils, this code is applicable.

This code covers prepared liquids for hydraulic transmission that do not contain significant amounts of petroleum oils. In contrast, HS-6 3818 includes hydraulic fluids that may contain higher levels of petroleum oils, which could affect your classification decision.

When considering HS-6 381900, think about the specific formulation of your hydraulic fluid. If it’s a synthetic brake fluid or a similar product that meets the criteria of containing less than 70% petroleum oils, this is the right classification.

Be aware that other related codes, such as HS-6 3820, cover different types of chemical preparations not specifically related to hydraulic applications. Ensure you select the correct code based on the intended use and composition of your product.
