Compliance steps

1
Identify the precise product type before procurement: power inverters for photovoltaic systems must conform to IS 16221 (Part 2):2015; utility-interconnected PV inverters with islanding prevention to IS 16169:2014; UPS/inverters of rating ≤10 kVA to IS 16242 (Part 1):2014; LED control gear to IS 15885 (Part 2, Sec 13):2012; IT-equipment power adaptors to IS/IEC 62368 (Part 1):2023; household-appliance adaptors to IS 302 (Part 1):2008. Verify the supplier holds a current BIS R-number against the correct standard for the specific product type.

2
Check the concurrent running window for IS 13252 (Part 1):2010 and IS 616:2017 against IS/IEC 62368 (Part 1):2023. For goods at Serial No. 65 of the Electronics QCO, concurrent running is permitted until 01-05-2026; for all other notified goods, until 01-11-2028, after which IS 13252 (Part 1):2010 and IS 616:2017 are withdrawn.

3
Ensure every unit bears the BIS Standard Mark with the supplier's R-number per Scheme-II of Schedule-II of the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product itself; packaging-only marking is insufficient.
Scheme-II of Schedule-II of the BIS (Conformity Assessment) Regulations, 2018 · BIS Act, 2016
4
Obtain Extended Producer Responsibility authorisation from the Central Pollution Control Board before importing UPS or inverter products. Micro enterprises registered under the MSMED Act, 2006 are exempt from EPR. Quote the EPR authorisation number on the bill of entry.
Schedule-I of the E-Waste (Management) Rules, 2022 · G.S.R. 801(E) dated 02-11-2022
5
Quote the BIS R-number on the bill of entry and ensure compliance with CBIC Instruction 27/2025-Cus dated 26-08-2025 (paragraphs 1 to 4) and DGFT Notification 13/24-25 dated 20-05-2024 with reference to FTP-2023 paragraph 2.31(1)(b) and policy conditions 5 and 7 of Chapter 85. Ensure Bureau of Energy Efficiency labelling compliance under Notification 5506/BEE/S&L/AL/2025-26 dated 26-12-2025.

A word of counsel

The single most common error on this tariff line is importing under a single R-number that does not match the specific product type in the consignment — for example, using an IS 16242 (Part 1):2014 registration for a UPS to clear a solar PV power inverter that requires IS 16221 (Part 2):2015 or IS 16169:2014. The BIS register is verified in real time at customs against the declared model code and standard; a standard-to-product mismatch triggers consignment detention even when the R-number itself is current and validly issued.

Frequently asked

Does HSN 8504 40 40 require BIS certification?

Yes. Voltage regulators, stabilisers, inverters, UPS units, and power adaptors falling under this tariff line require Bureau of Indian Standards registration under the Compulsory Registration Scheme against the applicable Indian Standard, with effect from 07 September 2012 under S.O. 2357(E) as amended.

Does one R-number cover all product variants under HSN 8504 40 40?

No. The R-number is standard-specific and model-specific; a UPS registered under IS 16242 (Part 1):2014 does not cover a solar PV inverter requiring IS 16221 (Part 2):2015 or a utility-interconnected inverter requiring IS 16169:2014. Each product type must be registered against its own applicable standard.

When do IS 13252 and IS 616 cease to be valid for concurrent running?

For goods at Serial No. 65 of the Electronics and Information Technology QCO, concurrent running of IS 13252 (Part 1):2010 and IS 616:2017 alongside IS/IEC 62368 (Part 1):2023 is permitted until 01-05-2026. For all other notified goods, concurrent running continues until 01-11-2028, after which both earlier standards are withdrawn.

Is EPR authorisation required for all importers of UPS and inverter products?

Yes, except for micro enterprises as defined in the Micro, Small and Medium Enterprises Development Act, 2006. EPR authorisation is administered by the Central Pollution Control Board under Schedule-I of the E-Waste (Management) Rules, 2022 and is independent of BIS Compulsory Registration.
