Silver oxide

Silver oxide primary cells and batteries

BIS QCO APPLICABLE · ISI MARK SCHEME · IS 8144 · CPCB OVERLAY

HSN 8506 40 00 (silver oxide primary cells and batteries) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 8144:2018 is mandatory under the ISI Mark Scheme, with the QCO obligation tracing to the Ministry of Consumer Affairs notification dated 25 May 1987. Extended Producer Responsibility authorisation under the Battery Waste Management Rules and the E-Waste Management Rules applies as a separate customs-clearance overlay administered by the Central Pollution Control Board.

Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 8144:2018 for multipurpose dry batteries. Verify the supplier's CM/L number, licensed product scope, and manufacturing facility address on the BIS online register before placing the purchase order.

2
Ensure every silver oxide cell and battery 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 packaging; marking on outer cartons alone does not satisfy the requirement.
BIS (Conformity Assessment) Regulations, 2018, Scheme-I of Schedule-II · S.O. 516(E) dated 25-05-1987
3
Obtain Extended Producer Responsibility authorisation from the Central Pollution Control Board under the Battery Waste Management (Amendment) Rules, 2023 before import. EPR certificates must be current and in force on the date of the bill of entry.
Battery Waste Management (Amendment) Rules, 2023 · S.O. 3984(E) dated 22-08-2022 · S.O. 4669(E) dated 25-10-2023
4
Verify separately whether EPR authorisation under the E-Waste Management Rules, 2022 is triggered by the product category. Micro enterprises as defined in the MSMED Act, 2006 are exempt from both EPR obligations; document the exemption basis if relied upon.
Schedule-I of the E-Waste Management Rules, 2022 · G.S.R. 801(E) dated 02-11-2022 · G.S.R. 338(E) dated 23-03-2016
5
Quote the supplier's BIS CM/L number and the CPCB EPR authorisation reference on the bill of entry. Customs verifies the CM/L in real time against the BIS register; an absent, expired, or scope-mismatched CM/L triggers consignment detention.

A word of counsel

The most common failure on this tariff line is treating the Battery Waste Management EPR obligation as the headline compliance item while overlooking the underlying BIS QCO. IS 8144:2018 governs the product itself; an importer who secures EPR authorisation but sources from a manufacturer whose CM/L is lapsed, facility-specific scope is mismatched, or does not cover the silver oxide chemistry will face detention and potential confiscation regardless of EPR status. Confirm CM/L scope maps precisely to silver oxide chemistry and cell size before the purchase order, not at the port.

Frequently asked

Does HSN 8506 40 00 require BIS certification?

Yes. Silver oxide primary cells and batteries require conformity to IS 8144:2018 under the ISI Mark Scheme; import is permitted only from manufacturers holding a current BIS CM/L licence covering the relevant product scope and manufacturing facility.

Is Extended Producer Responsibility authorisation required separately from BIS QCO compliance?

Yes. EPR authorisation under both the Battery Waste Management (Amendment) Rules, 2023 and the E-Waste Management Rules, 2022 is administered by the Central Pollution Control Board and is independent of the BIS obligation. Micro enterprises under the MSMED Act, 2006 are exempt.

Does IS 8144:2018 apply specifically to silver oxide batteries or to all primary batteries under HSN 8506?

IS 8144:2018 is cited in the QCO notification as the applicable standard for multipurpose dry batteries under this tariff line; importers should confirm with the licensed manufacturer that the CM/L scope expressly covers silver oxide chemistry.

Does a single CM/L licence cover all battery sizes and cell variants from one manufacturer?

No. A CM/L licence is scope-specific by product type, chemistry, size, and manufacturing facility; silver oxide cells outside the licensed scope, or produced at an unlicensed plant, are not covered.
