The Bureau of Indian Standards (BIS) launched “Scheme X” on March 16, 2022. Its main objective is to enable Indian and foreign manufacturers to get all types of assemblies, sub-assemblies, or machine tools under Schedule-II certified with the BIS mark before entering the Indian market.
BIS allows obtaining licenses or Certificates of Conformity (CoC) for low voltage switchgear and control gear, machinery, and electrical equipment under Scheme X. This enables manufacturers to use the BIS Standard Mark on their products, ensuring compliance with Indian standards and boosting consumer confidence.
Scheme X is a product certification scheme introduced under the BIS Conformity Assessment Regulations, 2018, and refined through the 2022 amendments. It aims to align Indian safety standards with global norms. It applies to machinery and electrical equipment manufactured or imported in India, requiring certification under Scheme X to meet technical and safety requirements.
The “Machinery and Electrical Equipment Safety (Omnibus Technical Regulation) Order, 2024” issued by the Ministry of Heavy Industries (effective August 28, 2025), covers items like pumps, compressors, cranes, rotary electrical machines, transformers, and switchgear. These, along with their components and sub-assemblies, must be certified under Scheme X unless explicitly exempted.
The OTR, titled “Machinery and Electrical Equipment Safety (Omnibus Technical Regulation) Order, 2024,” was issued on August 28, 2024. Its purpose is to enforce safety and conformity across all machinery, electrical equipment, and components covered under Scheme X. This regulation becomes mandatory from August 28, 2025.
Under the OTR Order, 2024, manufacturers of products like pumps, compressors, centrifuges, cranes, and transformers are required to obtain BIS certification under Scheme X. This helps ensure safety, reliability, and consumer trust in machinery and electrical products sold in India.
Micro, Small and Medium Enterprises (MSMEs) must also comply, helping them gain a competitive edge and adhere to safety standards.
Scheme X is mandatory for machine tools operating on stone, ceramic, concrete, asbestos cement, or mineral glass products, including assemblies. It was introduced by BIS to ensure compliance with Indian safety standards.
The BIS Standard Mark, used under Scheme X, includes a license number (e.g., CM/L-XXXXXXXXXX) and the relevant standard number. This mark is granted only after the successful issuance of a BIS license.
It is a punishable offense to use the BIS mark or a license number without valid certification. Manufacturers must strictly comply with BIS norms to sell their products legally in India.
