Complete Guide to BIS ISI Mark Certification in India: Process, Documents, Cost & Benefits
India has one of the world's most comprehensive product quality compliance systems. For manufacturers and importers, obtaining BIS ISI Mark Certification is often a mandatory requirement before products can be manufactured, imported, or sold in the Indian market. Products covered under Quality Control Orders (QCOs) cannot be legally marketed without the required BIS licence and ISI Mark.
Whether you are a domestic manufacturer or an overseas company planning to enter the Indian market, understanding the certification process can save both time and compliance costs.
What is BIS ISI Mark Certification?
BIS ISI Mark Certification is a product certification scheme operated by the Bureau of Indian Standards (BIS). The ISI Mark signifies that a product complies with the applicable Indian Standard (IS) and meets prescribed safety, quality, and performance requirements.
The certification is granted under Scheme-I of the BIS Conformity Assessment Regulations and is mandatory for hundreds of products notified under various Quality Control Orders issued by different ministries.

The manufacturer maintains a quality management system.
Every certified product carries:
ISI Logo
Applicable IS Standard Number
BIS Licence Number (CM/L Number)
What is an ISI Certificate?
An ISI Certificate is the licence issued by BIS that authorizes manufacturers to use the ISI Mark on eligible products.
This certificate confirms that:
