4010.36.50.00 - Other

This HTS code covers endless synchronous belts specifically designed for power transmission, manufactured from vulcanized rubber, and incorporating textile materials. The key defining characteristic for this subcategory is the composition of the textile components. These belts are designed for applications where precise speed and position control are critical, often found in machinery, automotive systems, and industrial automation.

This category is distinguished from its sibling, 4010.36.30.00, by the predominant fiber type within the textile reinforcement. While 4010.36.30.00 addresses belts where vegetable fibers (such as cotton or linen) are the most abundant, this code specifically pertains to belts where man-made fibers (like polyester, nylon, or aramid) constitute the largest proportion by weight of the textile components. This difference in material composition can affect the belt's strength, flexibility, heat resistance, and overall performance characteristics.

As a leaf node within the HTS structure, there are no further subcategories under 4010.36.50.00. Classification within this code is therefore determined solely by the presence of vulcanized rubber construction, its function as an endless synchronous transmission belt with an outside circumference between 150 cm and 198 cm, and the predominance of man-made fibers in its textile reinforcement. Importers and exporters should carefully examine the bill of materials and technical specifications to confirm the fiber composition of the textile elements to ensure accurate classification.
