4010.36.41.00 - Of a width exceeding 20 cm

This HTS category, 4010.36.41.00, specifically covers endless synchronous belts manufactured from vulcanized rubber that have an outside circumference exceeding 150 cm but not exceeding 198 cm. A key defining characteristic of these belts is the incorporation of textile materials, where man-made fibers constitute the predominant component by weight over any other single textile fiber. These belts are designed for power transmission applications, functioning as synchronous belts due to their toothed construction which ensures precise timing and eliminates slippage.

The classification of these belts is further refined by their width. This particular subheading is for belts with a width exceeding 20 cm. It's important to distinguish this from potential sibling categories, such as "Other" (4010.36.45.00), which would encompass synchronous belts with textile components where man-made fibers do not predominate by weight or other variations not explicitly covered here. The emphasis on the predominant use of man-made fibers within the textile reinforcement is crucial for accurate classification within this specific subdivision.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification within 4010.36.41.00 is final based on the criteria of being an endless synchronous belt, within the specified circumference range, with textile components dominated by man-made fibers, and exceeding 20 cm in width. Importers and exporters should ensure these physical and material characteristics are met to correctly classify their goods under this tariff item.
