Where the rubber compound content is less than 25% by weight
V-ribbed endless V-belts, low rubber compound content, medium circumference
HSN 4010 31 10 (V-ribbed endless V-belts with rubber compound content below 25% by weight, outside circumference 60–180 cm) is not covered by a Bureau of Indian Standards Quality Control Order and carries no Partner Government Agency clearance requirement at the tariff-line level. Import follows the standard customs procedure: Importer-Exporter Code, bill of entry, commercial invoice, packing list. Conveyor or transmission belts with higher rubber compound content, different cross-sections, or different circumference ranges are classified under sibling tariff lines within Chapter 40 that may carry distinct compliance obligations.
The principal risk at this tariff line is misclassification: rubber compound content percentage, belt cross-section geometry, and outside circumference are all classification determinants, and a customs officer finding that the rubber content meets or exceeds 25% by weight will re-classify the consignment to a sibling line — triggering retrospective compliance and potential detention. Importers should obtain a material composition certificate from the manufacturer confirming the rubber compound percentage before shipment.
