BIS QCO APPLICABLE · ISI MARK SCHEME · IS 17150 · PESO OVERLAY

HSN 8419 11 90 (instantaneous gas water heaters, other) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 17150:2019 is mandatory under the ISI Mark Scheme with effect from 01 March 2025 under the Electrical Appliances for Domestic Water Heating (Quality Control) Order, 2025; LPG-fired instantaneous heaters additionally require conformity to IS 15558 under a separate Quality Control Order. Petroleum and Explosives Safety Organisation approval applies as a separate customs-clearance overlay for consignments involving pressure vessels.

Compliance steps

1
Verify the foreign manufacturer's BIS CM/L licence number on the BIS online register against IS 17150:2019 for PNG-fired instantaneous water heaters, or against IS 15558 for LPG-fired variants. Confirm the licensed product scope, model range, and manufacturing facility address before placing the purchase order.

2
Ensure every unit bears the ISI mark and the supplier's CM/L number as required under Scheme-I of Schedule-II of the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the appliance itself, not on packaging alone.

3
Determine whether Petroleum and Explosives Safety Organisation approval is required for the consignment, particularly where the heater incorporates or is imported with pressure vessels or gas-handling components. Submit the manufacturer's particulars, ISO certificate, drawings, and third-party inspection certificate through the PESO online portal.

4
Quote the supplier's BIS CM/L number on the bill of entry and ensure it corresponds to the correct IS (17150:2019 for PNG heaters, IS 15558 for LPG heaters). Customs verifies the CM/L in real time; an absent, expired, or standard-mismatched licence triggers consignment detention.

5
If importing for research and development purposes, document that the importer is a manufacturer of electric appliances for domestic water heating and that the quantity does not exceed 200 units per year. Such goods must not be sold commercially and may be disposed of as scrap; a year-wise record must 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 indiscriminately to both PNG-fired and LPG-fired instantaneous heaters, when the two fuel-type variants are governed by different Quality Control Orders and different Indian Standards — IS 17150:2019 under S.O. 355(E) for PNG-fired appliances, and IS 15558 under S.O. 5244(E) for LPG-fired appliances. A CM/L licence scoped to one standard does not cover the other; importing LPG heaters on a CM/L issued against IS 17150:2019 (or vice versa) constitutes a scope mismatch that results in consignment detention at port regardless of whether the physical product is identical in construction.

Frequently asked

Does HSN 8419 11 90 require BIS certification?

Yes. Instantaneous gas water heaters under this tariff line require the ISI Mark under a current BIS CM/L licence — against IS 17150:2019 for PNG-fired heaters (mandatory from 01 March 2025) and against IS 15558 for LPG-fired heaters under the Domestic Water Heater for Use with Liquefied Petroleum Gas (Quality Control) Order, 2018.

Do small and micro enterprises face the same enforcement date?

No. Under the Electrical Appliances for Domestic Water Heating (Quality Control) Order, 2025, small enterprises as defined under the MSMED Act, 2006 have an implementation date of 01 June 2025, and micro enterprises of 01 September 2025, while the general enforcement date is 01 March 2025.

Is there an exemption for research and development imports?

Yes, but narrowly. The Quality Control Order exempts up to 200 units per year imported for R&D by manufacturers of electric appliances for domestic water heating; such goods may not be sold commercially, must be disposed of as scrap, and the importer must maintain and furnish year-wise records to the central government.

Does a single CM/L licence cover both PNG-fired and LPG-fired heater models?

No. The CM/L is standard-specific and model-specific; IS 17150:2019 and IS 15558 are separate standards under separate Quality Control Orders, and a licence issued against one does not authorise import of products within the scope of the other.
