3819.00.00.10 - Hydraulic brake fluids

This HTS classification, 3819.00.00.10, specifically covers hydraulic brake fluids. These are specially formulated liquid compositions designed for use in automotive and other hydraulic braking systems. Their primary function is to transmit force from the brake pedal to the braking mechanisms, ensuring efficient and reliable stopping power. The key characteristic for this classification is their explicit designation and use as hydraulic brake fluid.

This category is distinguished from its sibling, 3819.00.00.90 ("Other"), by its precise application. While the "Other" category encompasses a broader range of prepared liquids for hydraulic transmission not meeting the specific criteria of brake fluids, this particular code isolates only those products intended for braking systems. This distinction is crucial for accurate tariff assessment, as brake fluids often possess unique chemical compositions and performance requirements.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification hinges on the direct identification of the product as hydraulic brake fluid. Examples of goods falling under this code would include DOT 3, DOT 4, and DOT 5 brake fluids, provided they meet the explicit definition and do not contain or contain less than 70 percent by weight of petroleum oils or oils obtained from bituminous minerals, as specified in the parent category.
