What is BIS Certification?

The Bureau of Indian Standards (BIS) is the national standards body of India. It ensures that products made or sold in India meet quality and safety standards. The BIS operates under the Ministry of Consumer Affairs, Food & Public Distribution.

There are different types of BIS certifications, but the two most common are:

• ISI Mark Certification – for domestic manufacturers of various products like electrical appliances, cement, steel, and household items.

• BIS CRS Registration (Compulsory Registration Scheme) – mainly for electronic and IT products.

Whether you want to apply BIS certification for toys or get BIS CRS registration online, BIS ensures that only safe, reliable, and standardized products reach Indian consumers.

What is the ISI Mark?

The ISI Mark stands for the Indian Standards Institute — the former name of BIS. This mark proves that a product conforms to Indian standards.

You'll see the ISI mark on items like:

• Pressure cookers

• Cement bags

• Water heaters

• Wires and cables

• Packaged drinking water

For example, if you buy an electric iron or gas stove with an ISI mark, it means that product has passed quality checks under BIS norms.
