Rubber threads
Rubber threads of vulcanised rubber
HSN 4016 99 30 (Rubber threads) 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. Other articles of vulcanised rubber — particularly those used in automotive or industrial applications under Chapter 40 — may fall under sibling tariff lines that carry compliance obligations; classification accuracy is the principal importer risk.
The absence of compliance at this tariff line does not extend to all rubber articles within Chapter 40: rubber thread covered or wound with textile material is classified separately, and certain moulded or extruded rubber components for specific end-uses may attract product-specific obligations on re-classification. Customs examination that results in re-classification to a covered tariff line triggers retrospective compliance, including detention pending the relevant licence. Verify the precise product specification — vulcanisation process, textile covering, intended end-use — against the customs tariff before relying on the absence of compliance.
