4010.31.60.00 - Other

This HTS classification covers endless transmission belts, commonly known as V-belts or V-ribbed belts, that are manufactured from vulcanized rubber and possess an outside circumference greater than 60 cm but not exceeding 180 cm. These belts are specifically designed for transmitting power between rotating shafts in various machinery and equipment. Their trapezoidal cross-section is engineered to fit into corresponding grooved pulleys, ensuring efficient and stable power transfer.

This category is distinguished from its sibling, 4010.31.30.00, by the material composition. While this sub-heading exclusively covers V-belts made of vulcanized rubber, the sibling category specifically includes those combined with textile materials. Therefore, the presence or absence of reinforcing textile elements is the key differentiating factor at this level of classification.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification is complete at this point, meaning that belts meeting the defined criteria of vulcanized rubber construction, endless form, trapezoidal cross-section, and the specified circumference range will be classified under this code.
