Compliance steps

1
Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 17150:2019. Verify the supplier's CM/L number, licensed product scope covering the specific gas type (PNG or LPG), and licensed manufacturing facility on the BIS online register before placing the purchase order.

2
Identify which Indian Standard governs the specific fuel type of the consignment: IS 17150:2019 applies to mini domestic water heaters for piped natural gas (PNG); IS 15558 applies to instantaneous domestic water heaters for liquefied petroleum gas (LPG). The CM/L must correspond to the correct standard for the fuel type being imported.

3
Ensure every unit bears the ISI mark and the supplier's CM/L number per Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the appliance itself and not on packaging alone.

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 fuel-type-scope-mismatched licence triggers consignment detention, demurrage, and potential re-export.

5
If the consignment is imported for research and development by a manufacturer of electric appliances for domestic water heating, document the R&D exemption basis: maximum 200 units per year, no commercial sale permitted, scrap-disposal record to be maintained and furnished to the central government.

A word of counsel

The single most common error on this tariff line is applying a single CM/L licence across both PNG and LPG product variants when the two fuel types are governed by distinct Indian Standards — IS 17150:2019 for PNG and IS 15558 for LPG. A CM/L issued against one standard does not extend coverage to the other fuel type; importers who mix product variants under a single licence face detention of the non-covered units at port regardless of the overall BIS relationship with the supplier. Verify that the CM/L scope explicitly matches the fuel type stated on the commercial invoice before the purchase order is placed.

Frequently asked

Does HSN 8419 11 10 require BIS certification?

Yes. Instantaneous gas water heaters of the domestic type require a Bureau of Indian Standards CM/L licence against IS 17150:2019 (PNG) or IS 15558 (LPG) under the ISI Mark Scheme, mandatory with effect from 01 March 2025 under S.O. 355(E).

Do phased enforcement dates apply for small and micro enterprises?

Yes. Under S.O. 355(E), the enforcement date for small enterprises as defined under the MSMED Act, 2006 is 01 June 2025, and for micro enterprises it is 01 September 2025; the standard date of 01 March 2025 applies to all other importers.

Is the R&D import exemption available for all importers?

No. The exemption — capped at 200 units per year — is available only to manufacturers of electric appliances for domestic water heating; the imported units must not be sold commercially, must be disposable as scrap, and records must be maintained and furnished to the central government.

Does a single CM/L licence cover both PNG and LPG instantaneous water heater variants?

No. IS 17150:2019 (PNG) and IS 15558 (LPG) are separate standards requiring separate CM/L licences; a licence issued against one standard does not cover units manufactured to the other, and customs detains consignments on a standard-scope mismatch.
