Butadiene rubber (BR)

Butadiene rubber (BR), in primary forms or plates, sheets, strip

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 4002 20 00 (Butadiene rubber, BR) 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 synthetic rubber grades and compounded or vulcanised rubber articles within Chapter 40 may fall under distinct tariff lines that carry compliance obligations; classification by precise rubber type and physical form is the principal importer risk.

No partner government agency notification covers this tariff line.

A word of counsel

Butadiene rubber imported as a compounded blend with natural rubber (heading 4001) or pre-vulcanised must be classified with care — the physical form and compound state can shift the applicable tariff line and trigger compliance not present here. Customs re-classification on examination exposes the importer to detention pending the relevant licence and retrospective duty recovery. Verify the technical specification — polymer type, Mooney viscosity grade, oil-extended or non-extended — against the customs tariff before shipment.

Frequently asked

Does HSN 4002 20 00 require any pre-import registration?

A valid Importer-Exporter Code is required for any commercial import; no product-specific registration applies to this tariff line.

What changes if the butadiene rubber is compounded with natural rubber or supplied as a finished rubber article?

Compounded mixtures with heading 4001 products or finished rubber articles may fall under separate tariff lines within Chapter 40 that attract their own compliance requirements, including potential Quality Control Order coverage.
