Where the rubber compound content is less than 25% by weight
Vulcanised rubber conveyor belts, metal-reinforced, under 25% rubber compound
HSN 4010 11 10 (conveyor or transmission belts of vulcanised rubber, reinforced only with metal, 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 (IEC), bill of entry, commercial invoice, packing list. Other vulcanised rubber belting products within Chapter 40 — particularly those reinforced with textile or those with higher rubber compound content — may fall under sibling tariff lines that carry distinct compliance obligations.
The absence of compliance at this tariff line turns entirely on the declared rubber compound content and reinforcement type: a belt with 25% or more rubber compound content, or one reinforced with textile rather than metal alone, is classified differently within Chapter 40 and may attract BIS Quality Control Order coverage. Re-classification on customs examination — based on product specification, test reports, or composition declarations — triggers retrospective compliance and potential detention. Importers should retain third-party laboratory certification of rubber compound content and reinforcement composition prior to shipment.
