Styrene butadiene styrene oil-bound copolymer synthetic rubber

BIS QCO APPLICABLE · ISI MARK SCHEME · IS 11356

HSN 4002 19 30 (styrene butadiene styrene oil-bound copolymer) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 11356:2020 is mandatory under the ISI Mark Scheme with effect from 15 October 2021 under the Styrene Butadiene Rubber Latex (Quality Control) Amendment Order, 2024. No separate customs-clearance overlay beyond the BIS obligation applies to this tariff line.

Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 11356:2020 for styrene butadiene styrene oil-bound copolymer. Verify the supplier's CM/L number, licensed grade, and manufacturing facility on the BIS online register before placing the purchase order.

2
Ensure the consignment bears the ISI mark and the supplier's CM/L number in accordance with Scheme-I of Schedule-II of the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product or primary packaging unit, not solely on outer cartons.

3
Confirm with the supplier in writing that the grade being imported is not a carboxylated SBR latex grade intended for manufacture of automotive lithium-ion batteries. That specific grade is expressly carved out of the QCO and does not require BIS CM/L licensing under IS 11356:2020.

4
Quote the supplier's BIS CM/L number on the bill of entry and retain the test certificate showing conformity to IS 11356:2020 Mooney viscosity, bound-styrene content, volatile matter, and ash-content parameters. Customs verifies the CM/L against the BIS register; absent, expired, or scope-mismatched documentation triggers consignment detention.

A word of counsel

The single most common error on this tariff line is importing carboxylated SBR latex on a CM/L licence held against IS 11356:2020 and presenting it at customs as compliant — when the QCO itself carves out the carboxylated grade for automotive lithium-ion battery manufacture from the ISI-mark obligation entirely. The converse failure is equally costly: an importer of non-carboxylated SBR oil-bound copolymer who assumes the battery-grade carve-out extends to their product will arrive at port with no CM/L marking and face detention. Grade-level documentary confirmation from the supplier, tied to the specific carve-out language in S.O. 3957(E), must precede the purchase order.

Frequently asked

Does HSN 4002 19 30 require BIS certification?

Yes. Conformity to IS 11356:2020 is mandatory under the ISI Mark Scheme with effect from 15 October 2021; import is permitted only from manufacturers holding a current BIS CM/L licence covering the specific SBR grade and manufacturing facility.

Is the carboxylated SBR latex grade for automotive lithium-ion battery manufacture also covered by the QCO?

No. The Styrene Butadiene Rubber Latex (Quality Control) Amendment Order, 2024 under S.O. 3957(E) expressly exempts the carboxylated SBR latex grade intended for automotive lithium-ion battery manufacture from the ISI-mark obligation.

When did the BIS QCO obligation take effect for this tariff line?

The original Quality Control Order under S.O. 1626(E) fixed the date of effect at 15 April 2021; the 2024 amendment under S.O. 3957(E) dated 18 September 2024 introduced the carboxylated-grade carve-out but did not alter the original enforcement date.

Does a single CM/L licence cover all SBR grades and variants produced at a manufacturer's facility?

No. The CM/L is scope-specific by grade, specification parameter ranges (Mooney viscosity, bound-styrene content), and licensed manufacturing facility; grades or plants outside the licensed scope are not covered.
