4010.35.30.00 - With textile components in which vegetable fibers predominate by weight over any other single textile fiber

This HTS classification, 4010.35.30.00, specifically designates endless synchronous belts of vulcanized rubber with an outside circumference exceeding 60 cm but not exceeding 150 cm. A key defining characteristic of this category is that these belts incorporate textile components where vegetable fibers, by weight, constitute the predominant textile fiber. This means that if the belt contains a blend of textile fibers, the vegetable fiber content must outweigh any other single type of textile fiber present for it to fall under this classification.

This category is distinguished from its sibling category, 4010.35.50.00 ("Other"), by the specific composition of its textile reinforcement. While 4010.35.50.00 would cover endless synchronous belts within the specified size range that are combined with textile materials where man-made fibers predominate or where no single textile fiber predominates, 4010.35.30.00 is exclusively for those reinforced with vegetable fibers. The classification hinges on a precise weight analysis of the textile components.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification at this level is determined by the belt's dimensions (circumference), its function as an endless synchronous belt, its construction from vulcanized rubber, and crucially, the specific predominance of vegetable fibers within its textile reinforcement. Examples of such belts might include those used in agricultural machinery or specific industrial applications where the properties of vegetable fiber reinforcement are advantageous.
