4010.33.30.00 - Combined with textile materials 🖩

This HTS category encompasses endless transmission belts, specifically those with a trapezoidal cross-section (commonly known as V-belts) or V-ribbed belts, whose outside circumference measures between 180 cm and 240 cm, inclusive. These belts are constructed from vulcanized rubber and are designed for transmitting power within mechanical systems. The "combined with textile materials" descriptor indicates that these V-belts may incorporate textile reinforcement, such as cords or fabric plies, within their rubber structure to enhance tensile strength and durability.

The primary distinguishing factor for this specific subcategory, 4010.33.30.00, lies in its precise circumference range. It differentiates itself from the sibling category 4010.33.60.00, which covers "Other" endless transmission belts of trapezoidal cross-section (V-belts) and V-ribbed belts, implying that the sibling category likely encompasses belts with circumferences outside the 180 cm to 240 cm range, or potentially those with different structural compositions not specifically classified elsewhere within the 4010.33 heading.

As this is a leaf node within the HTS classification system, there are no further subcategories to introduce. Therefore, the classification of a product under 4010.33.30.00 hinges on its verification as an endless transmission belt of trapezoidal or V-ribbed cross-section, composed of vulcanized rubber (potentially with textile reinforcement), and falling within the specified outside circumference range of 180 cm to 240 cm.
