Conduct a Product Certification Gap Assessment
- Evaluate your current product models (inverters, converters, rectifiers) against applicable IS standards.Â
- IS/IEC 60146 series (for inverters, converters),
- IS/IEC 60204-1, IS 16504, and IS 16569.
- Use ERA’s compliance scoring to:
- Pinpoint non-compliant SKUs,
- Prioritize SKUs by commercial risk or government contract relevance.
Target high-risk SKUs before the 1 Sept 2026 deadline.

QCO Title & Notification
This product category is governed under the Machinery and Electrical Equipment Safety (Omnibus Technical Regulation) Order, 2024, notified via S.O. 3649(E) on 28 August 2024 and later amended through S.O. 2579(E) dated 12 June 2025. The Order is issued by the Ministry of Heavy Industries under the authority of Sections 16, 17, and 25 of the BIS Act, 2016.
Objective & Coverage
The QCO aims to ensure the safe design, performance, and conformity of power semiconductor converters, such as rectifiers, inverters, and power control units, before they are manufactured, sold, or imported in India. It covers all equipment and their associated parts operating under HS Code 850440, whether imported or domestically produced.
Effective Date
The Order will come into effect from 1 September 2026 for fully assembled converters. For components and sub-assemblies, a separate enforcement date will be notified in the official Gazette.
Certification & Scheme
Certification is mandatory under Scheme X of the BIS conformity assessment regime. The manufacturer or importer must obtain either:
- A License to use the ISI Mark, or
- A Certificate of Conformity (CoC), depending on product applicability.
Without certification, sale or import will be restricted post the effective date.
Pre-Certification Requirement
Before applying for certification, the manufacturer or importer must:
- Complete BIS registration.
- Select the applicable IS standards for the product.
- Submit a technical file with safety data, specs, risk assessment, and drawings.
- Undergo type testing in a BIS-recognized lab.
- Prepare for a factory inspection (if required by BIS).
Labeling & Compliance
Each certified unit must display:
- The ISI mark or CoC number.
- Manufacturer’s details and product type.
- Voltage and input/output ratings.
- Safety markings, warnings, and compliance with Scheme X labeling norms.
Applicable Indian Standards (IS Codes)
The relevant IS codes include:
- Type A: General safety design (IS 16819 based on ISO 12100).
- Type B: Electrical safety and control systems (IS/IEC 60204-1, IS 16504, IS 16569).
- Type C: Product-specific standard – IS/IEC 60146 series for power semiconductor converters.
If there’s a conflict between the standards, Type C (product-specific) standards take precedence over Type A or B.
Product Coverage, IS Standards, HS Codes, and Impacted Industries
| Product | HS Code | Applicable IS Codes | Standard Type | Impacted Industries |
|---|---|---|---|---|
| Power Semiconductor Converters | 850440: Electrical transformers, static converters (for example, rectifiers) and inductors static converters: electric inverter | IS/IEC 60146 series, IS/IEC 60204-1, IS 16504 | Type B, C | Power supply units, EV chargers, automation, OEMs |
Additional Notes
The Order enhances market surveillance and technical standardization by requiring conformity documentation, safety marking, and third-party testing. The regulation strengthens India’s energy systems and promotes quality infrastructure in critical sectors like renewables, e-mobility, and power automation.

- Electrical OEMs and power supply manufacturers.
- EV charging system manufacturers.
- Renewable energy equipment suppliers.
- Industrial automation & robotics companies.
- Importers and public procurement departments.
Exemptions
The Order shall not apply to:
- Products made exclusively for export.
- Items already regulated under other BIS QCOs.
- Items falling under MoRTH’s CMVR regulations.
Legal Consequences & Penalties
Non-compliance with the Order will result in penalties as per the BIS Act, 2016, including:

Summary & Next Steps
The QCO mandates that all power semiconductor converters (HS Code: 850440) comply with Indian Standards through BIS certification under Scheme X. Stakeholders must register with BIS, identify applicable IS standards (especially IS/IEC 60146), and complete the certification process before 1 September 2026. Sub-assemblies/components will be notified separately. Immediate preparation is required to ensure smooth compliance and avoid market restrictions.
