Where the rubber compound content is less than 25% by weight
V-ribbed transmission belts, outside circumference 180 to 240 cm, low rubber content
HSN 4010 33 10 (V-ribbed endless transmission V-belts of outside circumference exceeding 180 cm but not exceeding 240 cm, 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 transmission belts within Chapter 40 — particularly those with higher rubber compound content or different circumference ranges — may be classified under sibling tariff lines that carry distinct compliance obligations.
The principal importer risk at this tariff line is misclassification: the rubber compound threshold of less than 25% by weight is a hard criterion, and customs examination of a belt with a higher rubber content will trigger re-classification to the corresponding sibling line, potentially with retrospective compliance and detention. Automotive-use transmission belts may also draw scrutiny under industry-specific technical standards applicable to vehicle components under Chapter 40 broadly. Confirm the rubber compound percentage with a material test certificate before filing the bill of entry.
