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

2
Ensure every consignment lot 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 mark must appear on the primary packaging or the product itself, not on shipping documents alone.

3
Confirm in writing with the supplier that the grade being imported is not carboxylated SBR latex intended for the manufacture of automotive lithium-ion batteries. The QCO exemption for that specific grade must be documented with a manufacturer's declaration stating the intended end-use before the bill of entry is filed.

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 grade-mismatched licence triggers consignment detention, demurrage, and ground rent accumulation pending resolution.

A word of counsel

The most consequential error on this tariff line is assuming the carboxylated SBR latex exemption applies broadly to any latex grade destined for battery-related use. The exemption under S.O. 3957(E) is narrowly confined to carboxylated SBR latex for manufacture of automotive lithium-ion batteries specifically; all other grades — including non-carboxylated latex used in tyre, footwear, or general industrial rubber applications — require a current CM/L licence against IS 11356:2020. Importers who rely on a loosely worded supplier declaration without confirming the carboxylated grade specification face detention on the entire consignment.

Frequently asked

Does HSN 4002 11 00 require BIS certification?

Yes. Styrene butadiene rubber latex under this tariff line requires a Bureau of Indian Standards CM/L licence under the ISI Mark Scheme against IS 11356:2020, with effect from 15 October 2021, per S.O. 1626(E) and S.O. 3957(E).

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

Yes, but only for that specific grade and end-use. The Styrene Butadiene Rubber Latex (Quality Control) Amendment Order, 2024 carves out carboxylated SBR latex used in automotive lithium-ion battery manufacture; all other grades remain subject to mandatory ISI marking.

When did the IS 11356:2020 enforcement obligation take effect for this HSN?

Enforcement commenced on 15 October 2021 under S.O. 1626(E) dated 15 April 2021, as subsequently amended by S.O. 3957(E) dated 18 September 2024.

Does a single CM/L licence cover all SBR latex grades produced at a facility?

No. The CM/L is scope-specific by grade and manufacturing facility; latex grades or production lines outside the licensed scope are not covered, and a grade mismatch with the BIS register triggers detention at customs.
