5910.00.10 - Of man-made fibers

This HTS subheading, 5910.00.10, specifically classifies transmission or conveyor belts and belting that are constructed entirely of man-made textile fibers. This includes belts that may have undergone impregnation, coating, covering, or lamination with plastics, or reinforcement with metal or other materials, provided the primary textile component is man-made. The key defining characteristic for classification under this code is the origin of the textile fibers used in the belt's construction.

Within the broader category of textile transmission or conveyor belts, this subheading is distinguished from its sibling, 5910.00.90, which covers all "other" such belts. Therefore, if a belt is made from natural fibers or a blend where natural fibers predominate, it would fall under the "other" category. This distinction is crucial for accurate tariff assessment, as different fiber types can influence duty rates and trade regulations.

The subcategories under this heading, such as "Power transmission belts and belting" and "Other," further refine the classification based on the belt's specific function and material composition. For instance, the "Power transmission belts and belting" subcategory would likely encompass belts designed to transfer mechanical power, while the "Other" subcategory within the children would capture remaining types of man-made fiber belts not specifically delineated in further subdivisions.
