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 rubber. Verify the supplier's CM/L number, licensed grade scope, and manufacturing facility on the BIS online register before placing the purchase order.

2
Ensure every consignment bears the ISI mark and the supplier's CM/L number under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. The standard mark must appear on the product or its primary packaging.

3
Confirm that the imported grade is within the licensed IS 11356:2020 scope covering Mooney viscosity, bound-styrene content, volatile matter, and ash content parameters. Grades outside the CM/L scope are not covered, even if the supplier holds a CM/L for a different SBR grade.

4
If the consignment is carboxylated SBR latex solely for manufacture of automotive lithium-ion batteries, document the end-use basis and retain the declaration on file. The QCO exemption applies only to this specific grade and end-use; all other SBR grades and end-uses attract the CM/L requirement.

5
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 grade-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 importing a specific SBR grade — particularly carboxylated SBR latex — under the general IS 11356:2020 CM/L without confirming whether the end-use falls within the automotive lithium-ion battery exemption. The exemption is grade-specific and end-use-specific; an importer who claims it without documentary evidence of the battery-manufacturing end-use faces detention on the grounds that the CM/L is absent and no valid exemption basis has been established. Retain a manufacturer's declaration and end-use certificate on file before shipment.

Frequently asked

Does HSN 4002 19 90 require BIS certification?

Yes. Styrene butadiene rubber under this tariff line 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 exempt from the BIS QCO?

Only if the carboxylated SBR latex is exclusively for manufacture of automotive lithium-ion batteries. All other grades and end-uses attract the full CM/L requirement under the Styrene Butadiene Rubber Latex (Quality Control) Amendment Order, 2024.

What is the enforcement date difference between S.O. 1626(E) and S.O. 3957(E)?

S.O. 1626(E) dated 15 April 2021 is the original QCO notification, effective 15 October 2021. S.O. 3957(E) dated 18 September 2024 is the amendment order; both are in force and together constitute the current regulatory framework for this HSN.

Does a single CM/L licence cover all SBR grades from the same manufacturer?

No. The CM/L is grade-specific under IS 11356:2020; latex, oil-extended, high-styrene, and block-copolymer grades each require separate licensed scope, and consignments of grades outside the licensed specification are not covered.
