Where the rubber compound content is less than 25% by weight
V-belts (trapezoidal cross-section, 60–180 cm circumference, low rubber compound content)
HSN 4010 32 10 (endless trapezoidal V-belts of 60–180 cm outside circumference, where rubber compound content is less than 25% by weight) 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. V-belts with higher rubber compound content, or V-ribbed variants, are classified under sibling tariff lines within Chapter 40 that may carry distinct compliance obligations.
The critical classification variable here is rubber compound content by weight: belts meeting or exceeding 25% rubber compound content fall under a separate tariff line within Chapter 40, and a customs re-assessment of compound content on examination can trigger reclassification with retrospective compliance consequences including detention pending the relevant order. Importers should obtain a material composition certificate from the manufacturer before shipment, confirming that rubber compound content is below 25% by weight, and retain it as part of the import documentation set.
