Where the rubber compound content is less than 25% by weight
Conveyor or transmission belts, rubber compound under 25% by weight
HSN 4010 19 10 (conveyor or transmission belts of vulcanised rubber where the 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. Belts with a higher rubber compound content, or those classified under specific automotive or industrial sub-headings within Chapter 40, may fall under sibling tariff lines that carry compliance.
The principal risk at this tariff line is misclassification: if the rubber compound content of the imported belt meets or exceeds 25% by weight, a different sub-heading applies, and any Quality Control Order covering that line activates retrospectively on customs re-classification. Detention pending verification of compound content — typically established by test certificate — is the practical consequence of a content-threshold dispute at the port of entry. Importers should obtain a supplier material composition certificate confirming the rubber compound percentage before filing the bill of entry.
