Dip bridge rectifier

DIP bridge rectifiers and static converters (power adaptors, UPS, inverters)

BIS QCO APPLICABLE · CRS SCHEME · IS 16221 · BEE OVERLAY

HSN 8504 40 21 (DIP bridge rectifiers) is covered by a Bureau of Indian Standards Quality Control Order under the Compulsory Registration Scheme. Conformity to the applicable Indian Standard — IS 16242 (Part 1):2014 for UPS/inverters, IS 15885 (Part 2, Section 13):2012 for LED control gear, IS 302 (Part 1):2008 for household adaptors, and IS 16221 (Part 2):2015 or IS 16169:2014 for photovoltaic inverters — is mandatory with effect from 07 September 2012 under S.O. 2357(E) as amended. Bureau of Energy Efficiency labelling and Extended Producer Responsibility authorisation apply as separate customs-clearance overlays.

Compliance steps

1
Identify the precise sub-category of the consignment — photovoltaic power inverter, utility-interconnected inverter, UPS/inverter ≤10 kVA, LED control gear, IT-equipment power adaptor, AV-equipment power adaptor, or household-appliance adaptor — and verify the supplier's BIS R-number against the corresponding Indian Standard on the BIS online register before placing the purchase order.

2
Confirm the applicable IS by product type: IS 16221 (Part 2):2015 for PV power inverters; IS 16169:2014 for utility-interconnected PV inverters; IS 16242 (Part 1):2014 for UPS/inverters ≤10 kVA; IS 15885 (Part 2, Section 13):2012 for DC/AC LED control gear; IS 302 (Part 1):2008 for household-appliance adaptors. The R-number must be model-specific and current on the shipping bill date.

3
For IT-equipment and AV-equipment power adaptors registered under IS 13252 (Part 1):2010 or IS 616:2017, note the concurrent-running window: for goods at Serial No. 65, concurrent running with IS/IEC 62368 (Part 1):2023 is permitted until 01-05-2026; for all other goods, the window runs until 01-11-2028, after which IS 13252 (Part 1):2010 and IS 616:2017 are withdrawn.

4
If the consignment includes UPS/inverters, obtain Extended Producer Responsibility authorisation from the Central Pollution Control Board under the E-Waste (Management) Rules, 2022 before import. MSMED-registered micro enterprises are exempt. Quote the EPR authorisation number on the bill of entry.

5
Quote the BIS R-number on the bill of entry and ensure compliance with CBIC Instruction 27/2025-Cus dated 26-08-2025, DGFT Notification 13/24-25 dated 20-05-2024, and Bureau of Energy Efficiency (Appliance Labelling and Compliance) Regulations, 2026. Customs verifies each reference independently; any absent, expired, or scope-mismatched credential triggers consignment detention.

A word of counsel

The single most common error on this tariff line is treating the DIP bridge rectifier as a single product category with one IS number, when the QCO obligation bifurcates sharply by end-use application — photovoltaic inverters, UPS, LED drivers, IT adaptors, and household adaptors each carry a distinct Indian Standard and, in some cases, a distinct concurrent-running deadline. A consignment declared generically as 'static converters' without specifying the sub-category and corresponding R-number will be detained at port while customs seeks clarification on which IS applies, generating demurrage and ground rent that accumulates well before re-export or compliance rectification is possible.

Frequently asked

Does HSN 8504 40 21 require BIS certification?

Yes. DIP bridge rectifiers and associated static converters under this tariff line require Bureau of Indian Standards registration under the Compulsory Registration Scheme. The applicable IS varies by product sub-type — IS 16221 (Part 2):2015, IS 16169:2014, IS 16242 (Part 1):2014, IS 15885 (Part 2, Section 13):2012, or IS 302 (Part 1):2008 — with effect from 07 September 2012.

Is Extended Producer Responsibility authorisation required alongside BIS CRS compliance?

Yes, for UPS and inverter imports. EPR authorisation is administered by the Central Pollution Control Board under the E-Waste (Management) Rules, 2022 and is independent of the BIS obligation. Micro enterprises as defined in the Micro, Small and Medium Enterprises Development Act, 2006 are exempt.

What is the concurrent-running window for IS 13252 and IS 616 with IS/IEC 62368 (Part 1):2023?

For goods at Serial No. 65, the concurrent-running period ends on 01-05-2026; for all other covered goods, it ends on 01-11-2028, after which IS 13252 (Part 1):2010 and IS 616:2017 are withdrawn. Importers must plan R-number transitions to IS/IEC 62368 (Part 1):2023 before the relevant deadline.

Does a single R-number cover all variants of a DIP bridge rectifier product line?

No. The R-number is model-specific and IS-specific; variants outside the registered model code, or products falling under a different applicable IS than the one against which the R-number is registered, are not covered and trigger detention on a scope mismatch.
