Isobutene-isoprene and other synthetic rubber, primary forms or strip
HSN 4002 39 00 (other isobutene-isoprene and related synthetic rubber in primary forms, plates, sheets, or strip) 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. Synthetic rubber grades used in specific downstream applications — such as vulcanised rubber articles or automotive components covered under Chapter 40 product-specific Quality Control Orders — may attract compliance at the finished-goods level rather than the raw-material tariff line.
The absence of compliance at the raw-material tariff line does not insulate finished or semi-finished rubber articles derived from this input: several downstream tariff lines in Chapter 40 are subject to Quality Control Orders applicable to vulcanised rubber products, hoses, and automotive parts. Misclassification risk is elevated where the import arrives in a form that customs may re-examine as a fabricated rubber article rather than a primary form — detention pending re-classification and retrospective duty recovery follow. Confirm that the imported goods meet the primary-form or strip criterion before relying on the clean compliance position at this tariff line.
