What Is BIS Certification?

BIS Certification refers to the product certification (also called conformity assessment) system administered by the Bureau of Indian Standards (BIS), the National Standards Body of India.

BIS operates under the Bureau of Indian Standards Act 2016 (Ministry of Consumer Affairs, Food & Public Distribution, Government of India) and is responsible for:

• Development of Indian Standards (IS)
• Conformity assessment (Product certification)
• Hallmarking of Jewellery
• Testing of Products and Laboratory recognition
• Promotion of Standards
• Consumer protection through standardization

In simple terms, BIS certification is a verification that a product conforms to applicable Indian Standards with respect to:

• quality
• safety
• performance
• reliability
• durability
• environmental requirements etc. as specified in the Standard.

Depending on the product category and applicable regulations, BIS certification may either be:

• Voluntary
  or
• Mandatory

For many regulated products covered under Quality Control Orders (QCOs), BIS certification becomes mandatory for manufacture, import, sale, or distribution in the Indian market.

The certification process generally involves the following steps:

• identification of applicable standards
• submission of application
• product testing
• factory assessment or inspection
• verification of manufacturing infrastructure
• evaluation of quality control systems
• grant of license or registration

The exact process varies depending on the applicable BIS scheme.

Why BIS Certification Matters

BIS certification serves multiple purposes for regulators, consumers, manufacturers, and businesses. We will describe this in detail in the following section.
