4010.39.10.00 - Combined with textile materials:

This HTS category, 4010.39.10.00, specifically covers conveyor or transmission belts and belting made of vulcanized rubber that are combined with textile materials. These are transmission belts, meaning they are designed to transfer power from one shaft to another, and they possess a trapezoidal cross-section, commonly referred to as V-belts. The presence of textile materials within their construction is a defining characteristic for this classification.

The key distinction from its sibling, 4010.39.20.00, lies in the material composition. While both fall under "Other" transmission belts of trapezoidal cross-section, this specific code requires the inclusion of textile materials. Therefore, if a V-belt does not incorporate textile reinforcement or components, it would likely be classified under the "Other" sibling category.

As this is a leaf node, there are no further subcategories. Classification within 4010.39.10.00 is determined by the presence of both a V-belt design and the integration of textile materials to enhance strength, durability, or other performance characteristics. This ensures precise identification for import and export purposes based on the physical attributes and construction of the belting.
