4010.39.20.00 - Other

This HTS category, 4010.39.20.00, classifies transmission belts and belting made of vulcanized rubber that are not of a combined textile material construction. These belts are specifically designed for transmitting power between rotating shafts in machinery, encompassing a broad range of applications where mechanical power transfer is required. Examples include belts used in automotive engines, industrial equipment, agricultural machinery, and other mechanical systems. The "Other" designation at this level signifies that these transmission belts do not fall under more specific classifications within the broader category of transmission belts or belting.

This classification is distinguished from its sibling category, 4010.39.10.00, which specifically covers transmission belts and belting that are combined with textile materials. Therefore, to be classified under 4010.39.20.00, the transmission belts must be solely or primarily composed of vulcanized rubber, without significant integration of textile reinforcement or components that would classify them as combined. The absence of textile integration is a key distinguishing factor.

As this is a leaf node, there are no further subcategories for this specific HTS code. Classification within this category relies on fulfilling the criteria of being a transmission belt or belting of vulcanized rubber and not meeting the requirements for the sibling category (combined with textile materials). The emphasis remains on the material composition and functional purpose of the rubber belting.
