Introduction

In response to evolving safety and quality demands for industrial machinery and electrical gear, the Bureau of Indian Standards (BIS) introduced Scheme X under the Omnibus Technical Regulation (OTR). Designed for high-risk, technical products like pumps, compressors, switchgear, HVAC systems, and more, Scheme X offers a streamlined approach to BIS certification—especially beneficial for experienced manufacturers.

This certification has been deemed mandatory for compliant market entry by September 1, 2026. At Diligence Certification, we offer specialized support to help both domestic and foreign manufacturers navigate Scheme X quickly and accurately.

What Is BIS Scheme X?

BIS Scheme X is a compliance pathway introduced under the OTR 2024, targeting machinery and electrical equipment not covered by older BIS regulations. Its key features:

• Simplified conformity via third-party lab reports and documentation
  
  

• Extended license validity—up to 3–6 years
  
  

• Reduced surveillance audits for trusted manufacturers
  
  

• Designed to accelerate certification and ensure safety, performance, and market access
  
  

It’s a critical option for companies manufacturing or importing high-risk equipment into India.

2. Scope & Product Categories

Scheme X applies to a wide range of industrial and electrical categories such as:

• Pumps, compressors, centrifuges
  
  

• Switchgear, control panels, transformers
  
  

• Electric motors, HVAC systems
  
  

• Cranes, lifting equipment, conveyors
  
  

• Welding machines and agricultural machinery
  
  

• Machine tools, filtration units, and related assemblies
  
  

Importantly, only manufacturers—not traders—are eligible to apply, and products must meet applicable IS standards such as IS 16819 (safety design) or the IS/IEC 60947 series.

3. Why Scheme X Matters

Mandatory Compliance in India: The OTR 2024 makes Scheme X obligatory for listed categories by September 2026

Compliance Speed: Scheme X reduces turnaround time due to reliance on documentation over frequent audits

Enhanced Credibility: Certified products stand out in B2B and government tender processes

Longer Validity: Licenses typically last 3–6 years, easing administrative burden

Global Readiness: Aligns with international conformity norms, making Indian certification globally relevant

4. Eligibility Criteria

Not every manufacturer qualifies. Key eligibility factors include:

• Holding a valid BIS Scheme I license
  
  

• At least 3 years of clean regulatory compliance
  
  

• Operational in-house lab with documented Standard Operating Procedures (SOPs)
  
  

• Robust Quality Management System (QMS) in place, preferably ISO 9001
  
  

• Strong product traceability and batch control mechanisms

6. Certification Process: Step-by-Step

For Domestic Manufacturers

1. Assess eligibility (license, compliance history, lab capabilities)
   
   

2. Gather documentation: company details, lab SOPs, product specs
   
   

3. Submit application via BIS portal with relevant fees
   
   

4. Provide third-party lab test reports for compliance
   
   

5. BIS reviews application; audits may be limited or waived
   
   

6. Upon approval, you receive Scheme X license and logo usage rights
   
   

7. Maintain compliance and prepare for occasional surveillance checks
   
   

For Foreign Manufacturers

• Appoint an Authorized Indian Representative (AIR)
  
  

• Submit the same documents and test reports—audits may occur in India or abroad
  
  

• Expect a 6–7 month timeline due to logistics and remote verification
  
  

7. Required Documentation & Testing

Manufacturers must submit:

• Company PAN, GST, facility addresses
  
  

• Quality manuals, lab SOPs, product specs
  
  

• Test reports from BIS-recognized or accredited labs
  
  

• Evidence of compliance history (production logs, audit reports)
  
  

• Packaging/labeling designs with Scheme X mark placement
