BIS ISI Mark Certification in India: Process, Documents and Benefits

Author : PSR Compliance | Published On : 10 Nov 2026

If you manufacture or sell products in India, product quality and safety are important for building customer trust. The Bureau of Indian Standards (BIS) provides certification to ensure that products meet the required Indian Standards. One of the most recognised certifications is the BIS ISI Mark Certification.

The ISI Mark indicates that a product has been assessed and certified under the applicable Indian Standard through the relevant BIS certification scheme. It is mandatory for several products covered under Quality Control Orders (QCOs).

Manufacturers dealing with regulated products must understand the certification requirements before manufacturing, selling, importing or distributing products in the Indian market.

What Is BIS ISI Mark Certification?

BIS ISI Mark Certification is a product certification scheme operated by the Bureau of Indian Standards (BIS) under the BIS Act, 2016.

It allows eligible manufacturers to use the ISI Mark on products that meet the applicable Indian Standard and have received the required BIS licence.

The ISI Mark helps consumers identify products that comply with specified quality, performance and safety requirements.

Some common product categories that may require ISI certification include:

  • Cement and construction materials

  • Electrical appliances and equipment

  • Steel and metal products

  • Pressure cookers

  • Automotive components

  • Household products

  • Packaged drinking water

  • Industrial machinery and equipment

The exact certification requirement depends on the applicable Indian Standard and government notifications.

Why Is BIS ISI Certification Important?

BIS ISI Mark Certification provides several benefits to manufacturers and businesses.

1. Legal Compliance

Products covered under mandatory BIS certification requirements must comply with the applicable regulations before being sold in India.

2. Customer Confidence

The ISI Mark helps customers identify products that meet recognised Indian quality and safety standards.

3. Better Market Opportunities

BIS certification can help manufacturers build credibility with distributors, retailers, government buyers and business partners.

4. Product Quality Assurance

The certification process involves product testing and factory assessment to verify compliance with relevant standards.

5. Brand Reputation

Using the ISI Mark under a valid BIS licence can strengthen the reputation of a manufacturing business.

BIS ISI Mark Certification Process in India

The BIS certification process involves multiple stages. Manufacturers must complete the applicable requirements before receiving permission to use the ISI Mark.

Step 1: Identify the Applicable Indian Standard

The first step is to identify the Indian Standard applicable to the product. Manufacturers should also check whether their product falls under a mandatory Quality Control Order.

Step 2: Prepare the Required Documents

Collect business, factory, manufacturing and product-related documents. Ensure that the information is accurate and matches the actual manufacturing setup.

Step 3: Submit the BIS Application

Submit the application through the applicable BIS process with the required details and supporting documents.

Step 4: Factory Inspection

BIS may conduct a factory inspection to assess manufacturing facilities, production processes, quality control systems and testing arrangements.

Step 5: Product Testing

Product samples are tested against the relevant Indian Standard at a BIS-recognised laboratory, as required under the applicable scheme.

Step 6: Application Review and Licence Grant

After reviewing the inspection findings, test reports and other requirements, BIS decides whether to grant the licence.

Step 7: Use of ISI Mark

Once the licence is granted, the manufacturer can use the ISI Mark according to the conditions and marking requirements specified by BIS.
