3917.40.00.10 - For brake hoses for the vehicles of subheadings 8701.21, 8701.22, 8701.23, 8701.24 or 8701.29 or headings 8702, 8703, 8704, 8705 or 8711

This HTS category, 3917.40.00.10, specifically classifies plastic fittings designed for brake hoses. These fittings are intended for use with vehicles falling under subheadings 8701.21 through 8701.29, or headings 8702, 8703, 8704, 8705, or 8711. The primary function of these fittings is to connect or terminate brake hoses, ensuring the secure and leak-free transfer of hydraulic fluid within a vehicle's braking system. Their construction from plastic materials and their specific application in automotive braking systems are key classification determinants.

While other fittings for tubes, pipes, and hoses are classified under the broader heading 3917.40, this particular subheading is distinct due to its specialized application. Unlike general plumbing fittings, which may be designed for water distribution or drainage and are categorized under sibling entries like "Plumbing fittings, not pressure rated (Drain/Waste/Vent (DWV))" or "Other plumbing fittings," these brake hose fittings are engineered to withstand the pressures and demands of a vehicle's braking system. The sibling category "Other" (3917.40.00.95) serves as a residual category for plastic fittings not otherwise specified, making the precise application of a fitting crucial for correct classification.

As this node is a leaf node, there are no further subcategories. Classification at this level therefore relies on a precise identification of the fitting's intended use with specific vehicle types and its role within a brake hose system. Examples of such fittings might include connectors, adapters, or unions that attach brake hoses to components like wheel cylinders, master cylinders, or anti-lock braking system (ABS) modules. The material being plastic and the functional requirement for brake hose connection are the definitive criteria for goods falling under this classification.
