The ISI Certificate, issued by the Bureau of Indian Standards (BIS), is a prestigious quality mark that assures consumers that a product meets Indian safety and performance standards. In 2026, getting an ISI Certificate has become essential for manufacturers who want legal market access, consumer trust, and a competitive edge. Whether you produce food items, electrical appliances, steel products, cement, or consumer goods, the ISI Mark adds significant value to your brand.

This easy-to-follow guide explains the complete step-by-step process to apply for an ISI Certificate in a simple and practical way, helping both new and experienced manufacturers complete the process smoothly.

What is ISI Certificate?

The ISI Mark is part of BIS’s Product Certification Scheme. Unlike the CRS scheme (mainly for electronics), the ISI Certificate requires factory inspection, quality control systems, and regular surveillance. It is mandatory for many product categories and voluntary for others. Once granted, you can use the famous ISI logo on your products and packaging.

Why ISI Certificate is Important

The ISI Mark builds instant consumer trust, helps products stand out in the market, and is often required for government tenders and large institutional orders. It also ensures consistent product quality through regular BIS audits. For food product manufacturers, in particular, the certification carries extra importance due to health and safety concerns.

Step-by-Step Process to Apply for ISI Certificate Easily

Step 1: Check Product Applicability Visit the official BIS website and confirm whether your product falls under compulsory certification. Identify the exact Indian Standard (IS) code for your product. This initial step prevents unnecessary applications and saves time and money.

Step 2: Business and Factory Preparation Ensure your manufacturing unit meets basic infrastructure requirements. Appoint qualified technical staff and set up a proper quality control laboratory. Maintaining good manufacturing practices (GMP) from the beginning makes the later inspection process much easier.

Step 3: Product Testing Send product samples to a BIS-recognized laboratory for testing as per the relevant Indian Standard. The test report is one of the most important documents in your application. Choose a reputed lab to avoid delays or re-testing.

Step 4: Register on Manak Online Portal Go to manakonline.in and create a company account. Fill in accurate business details including GST, PAN, address, and contact information. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).

Step 5: Submit Online Application Log into the portal, select the ISI Mark scheme, fill the detailed application form, upload the test report and other documents, and pay the required fee. Double-check all entries before final submission.

Manufacturers often seek clarity on differences between various BIS schemes. You can refer to ISI Certificate for Manufacturers for better understanding.

Step 6: Factory Inspection by BIS After application scrutiny, BIS officers will visit your factory. They check manufacturing processes, quality control systems, testing facilities, and record-keeping. Prepare your factory, train your staff, and keep all records ready. This is a crucial step — a well-prepared factory usually gets faster approval.

Step 7: Respond to Queries BIS may raise queries during the review process. Reply promptly with correct information or additional documents. Quick responses significantly reduce overall processing time.

Step 8: Grant of ISI Certificate Once everything is approved, BIS grants the ISI Certificate and license number. You can then legally print the ISI Mark on your products as per guidelines and start commercial sales.
