Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 11356:2020 for oil extended styrene butadiene rubber. Verify the supplier's CM/L number, licensed product scope, and manufacturing facility on the BIS online register before placing the purchase order.
Styrene Butadiene Rubber Latex (Quality Control) Amendment Order, 2024 · S.O. 1626(E) dated 15-04-2021 · S.O. 3957(E) dated 18-09-2024
2
Ensure each consignment unit bears the ISI mark and the supplier's CM/L number under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product or its primary container — not on outer packaging alone.

3
Confirm in writing that the consignment is not carboxylated SBR latex grade intended for manufacture of automotive lithium-ion batteries. That specific grade is expressly carved out of the QCO; importing it without the exemption documentation invites reclassification risk and detention.

4
Quote the supplier's BIS CM/L number on the bill of entry. Customs verifies the CM/L in real time against the BIS register; an absent, expired, or scope-mismatched licence triggers consignment detention, demurrage, and potential re-export or confiscation.

A word of counsel

The single most common error on this tariff line is failing to distinguish oil extended SBR from carboxylated SBR latex grades destined for automotive lithium-ion battery manufacture — the latter is expressly exempt from the QCO. Importers who ship carboxylated grades without documentary proof of the battery-manufacture end-use face the full BIS enforcement regime; equally, those who wrongly invoke the exemption on standard oil extended grades face detention and monetary penalty under the BIS Act, 2016. Obtain a supplier-issued grade-specific certificate confirming end-use before the purchase order is placed.

Frequently asked

Does HSN 4002 19 10 require BIS certification?

Yes. Oil extended styrene butadiene rubber must conform to IS 11356:2020 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 relevant grade and facility.

Is carboxylated SBR latex for automotive lithium-ion battery manufacture exempt from the QCO?

Yes. The Styrene Butadiene Rubber Latex (Quality Control) Amendment Order, 2024 expressly excludes carboxylated SBR latex grade intended for manufacture of automotive lithium-ion batteries. Documentary evidence of the end-use must be maintained and produced on demand.

What is the operative enforcement date — 15 April 2021 or 15 October 2021?

15 October 2021 is the operative date for mandatory conformity to IS 11356:2020 as stated in the CCR; S.O. 1626(E) dated 15 April 2021 is the original QCO notification date. Both references are live and cited in the controlling order.

Does a single CM/L licence cover all grades and facilities of the manufacturer?

No. The CM/L is scope-specific by rubber grade, Mooney viscosity range, and manufacturing facility; grades or plants outside the licensed scope are not covered, and a mismatch triggers detention at port.
