Isoprene rubber, other than latex, in primary forms
HSN 4002 49 00 (isoprene rubber, other than latex, in primary forms or in 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. Finished rubber articles — tyres, seals, hoses — classified elsewhere in Chapter 40 may attract compliance obligations that do not apply to this upstream synthetic rubber input.
The absence of compliance at this tariff line reflects its classification as a raw synthetic rubber input; downstream rubber products manufactured from or incorporating isoprene rubber frequently carry BIS Quality Control Order obligations under other Chapter 40 headings. Customs re-classification — for instance, to a latex-form or vulcanised-rubber tariff line — triggers retrospective compliance and potential detention. Verify the precise physical form, vulcanisation state, and intended end-use against the tariff schedule before confirming classification.
