Compliance steps

1
Identify the precise sub-type of the consignment and match it to the applicable Indian Standard: IS 12933 (Parts 1 and 2):2003 for solar flat-plate collectors, IS 16544:2016 for all-glass evacuated tube systems, IS 16542:2016 for their storage water tanks, IS 15558 for LPG instantaneous heaters, and IS 302-2-201 for electric immersion heaters. Verify the supplier's BIS CM/L licence number on the BIS online register against the specific IS and manufacturing facility before placing the purchase order.
S.O. 4485(E) dated 08-10-2024 · S.O. 5244(E) dated 10-10-2018 · S.O. 189(E) dated 17-02-2003
2
Ensure every article 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 itself; marking only on packaging does not satisfy the requirement.

3
For LPG instantaneous water heaters, verify PESO approval in addition to the BIS CM/L licence. Import of pressure vessels and associated equipment requires Petroleum and Explosives Safety Organisation authorisation under the Gas Cylinders Rules, 2016.

4
Ensure compliance with the Bureau of Energy Efficiency (Appliance Labelling and Compliance) Regulations, 2026 for products within the labelling scope. Quote the BEE labelling reference in the consignment-level documentation.

5
Quote the supplier's BIS CM/L number — and, where applicable, PESO approval details and the BEE labelling reference — on the bill of entry. Customs verifies the CM/L in real time against the BIS register; an absent, expired, or IS-scope-mismatched licence triggers consignment detention.

A word of counsel

The single most common error on this tariff line is presenting a single CM/L licence that covers one water-heater sub-type as sufficient for a mixed consignment spanning multiple sub-types — for example, a licence against IS 12933 for flat-plate solar collectors does not extend to evacuated tube systems under IS 16544:2016 or to LPG instantaneous heaters under IS 15558. Each sub-type requires its own IS-specific CM/L, and customs can detain on a sub-type mismatch even when the primary product in the consignment is fully certified.

Frequently asked

Does HSN 8419 19 20 require BIS certification?

Yes. Multiple Indian Standards apply depending on sub-type: IS 12933 for solar flat-plate collectors, IS 16544:2016 for evacuated tube systems, IS 16542:2016 for associated storage tanks, IS 15558 for LPG instantaneous heaters, and IS 302-2-201 for electric immersion heaters. All require a current BIS CM/L licence under the ISI Mark Scheme.

Is PESO approval required in addition to BIS QCO compliance?

Yes, for LPG instantaneous water heaters and pressure vessels. Petroleum and Explosives Safety Organisation approval under the Gas Cylinders Rules, 2016 is a separate requirement, independent of the BIS CM/L licence obligation under S.O. 5244(E).

When did the solar water heating systems BIS QCO obligation take effect?

The obligation under S.O. 4485(E) for solar flat-plate collectors (IS 12933) and all-glass evacuated tube systems (IS 16544:2016 and IS 16542:2016) took effect from 14 April 2025. LPG instantaneous heaters under IS 15558 have been notified since S.O. 5244(E) dated 10 October 2018.

Does one CM/L licence cover all water heater variants from the same manufacturer?

No. Each CM/L licence is specific to the Indian Standard, product sub-type, and manufacturing facility; a licence for one sub-type does not cover variants falling under a different IS, and customs detains consignments where the CM/L scope does not match the imported goods.
