Chemically modified form of natural rubber including graft rubber
Chemically modified natural rubber and graft rubber mixtures
HSN 4002 80 20 (chemically modified natural rubber including graft rubber) 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 products within Chapter 40 — including finished rubber articles or tyres — may carry compliance obligations, making precise classification against the tariff description essential before shipment.
The principal risk at this tariff line is misclassification: chemically modified or graft rubber that has been further processed into sheets, strips, or compounded mixtures may be re-classified by customs into a tariff line that does attract compliance under Chapter 40. Retrospective re-classification exposes the importer to detention pending the applicable clearance and recovery of differential duty. Confirm that the product specification — degree of chemical modification, physical form, and intended downstream use — squarely fits the heading 4002 80 20 description before relying on the absence of compliance.
