Where the rubber compound content is less than 25% by weight
V-belts (180–240 cm circumference) with under 25% rubber compound
HSN 4010 34 10 (V-belts of trapezoidal cross-section, outside circumference exceeding 180 cm but not exceeding 240 cm, with rubber compound content below 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 conveyor or transmission belts under Chapter 40 — particularly those with higher rubber compound content or different dimensional specifications — may fall under sibling tariff lines that carry distinct compliance obligations.
The principal importer risk at this tariff line is misclassification: the rubber compound content threshold (below 25% by weight) and the precise outside circumference range (exceeding 180 cm but not exceeding 240 cm) are both measurable parameters that customs examination can challenge. A re-classification to a sibling belt tariff line — whether for higher rubber content, a different circumference band, or V-ribbed construction — triggers retrospective compliance and detention pending resolution. Verify laboratory test data confirming rubber compound percentage and belt dimensions before filing the bill of entry.
