Whenever you purchase a product from the market you see an ISI mark on it. Sometimes you must wonder why this mark is used on the product, who provides certification for this mark, etc. In India, there are two standards to verify and clarify whether a product is valuable or complies with set standards or not. The ISI certification gives assurance of high-quality products in India. BIS is an organisation that provides ISI certification. 


To get the certification every product needs to pass certain quality standards to be sold in the market. Below is the comparison between BIS certification and ISI certification.

What is BIS Certification?

The BIS stands for Bureau of Indian Standards. When the ISI mark was established, there was a lack of standardized regulations. So, to ensure the growth of the economy and ensure uniformity in standardised practice, the BIS Act was launched on December 23rd, 1986.


The BIS took all the activities which are handled by ISI previously. Now the ISI certification comes under BIS. The following activities come under the BIS:

  • Creating guidelines and rules of standardisation
  • Certifying products
  • Awarding Trademark
  • Granting Patents

In the BIS Act, of 1986 there was a problem, in that the act was only focusing on certifying producers and not the material. So, the 1986 act was replaced with the BIS Act 2016. 


However, there was a problem with the 1986 BIS Act - it only focused on certifying producers, not the materials themselves. This new act was certifying the quality of the material. As per the act, the consumers will get compensation if their purchased product does not meet the standards. And, the companies which don’t follow the regulations will face punishment in terms of fines or imprisonment.

What is ISI Certification?

The ISI stands for Indian Standards Institution. The certificate comes under the BIS scheme to ensure that the product follows the BIS Standards and Safety. It was founded on January 6th, 1947 to safeguard the interests of consumers and implement a certification mark scheme. 


With time as the economy evolved, a more robust organisation, the Bureau of Indian Standards (BIS), was established to provide standardisation for industrial products. The ISI mark still indicates that a product has received a high-quality certification.


The ISI mark on Indian products signifies that the product meets all the guidelines set by the government of India and has been certified for quality assurance. Some advantages of the ISI marks are as follows:

  • Products that have the ISI mark have undergone a comprehensive evaluation and investigation to ensure that the product has high-quality standards.
  • If a customer is not satisfied with a product that bears the ISI mark, they can return it to the manufacturer for a replacement. 
  • If a customer is not happy with a product bearing the ISI mark, they may also file a complaint with the manufacturer.

Difference between Certification of WPC and BIS 

The following are the differences between WPC certification and BIS certification:

Parameters of comparison



What it stands for

BIS stands for the Bureau of Indian Standards.

ISI stands for Indian Standards Institution.


Maintaining the service and quality of a product is the main job of the Bureau of Indian Standards (BIS).

ISI mark on a product is an assurance that the product has high quality and follows the regulations set by the government.


BIS allot the ISI mark to products as a guarantee after ensuring their quality, reliability and safety.

The purpose of ISI is to provide certification for Indian products as well as protect local manufacturers.

Time of origin

BIS originated on 26 November 1986.

ISI was established on 6 January 1947.

Covered Products

The BIS certification is provided for industrial products. 

The ISI certification is provided for electric appliances.

Changes in the legislation

To change the BIS Act of 1986 the notification was passed on 22 March 2016 and it was forced into effect from 12 October 2017.

The ISI certification was overtaken by BIS certification in 1986. 

Advisory Body

BIS has a group of people called the Certification Advisory Committee. This provides certification for the product.

The ISI does not have an advisory body.


BIS works on providing the certification for the quality of the product as well as the company.

ISI only provides the assurance that products have the highest quality.


To conclude, it is evident that both the marks guarantee the consumer that the product is of high quality. When a product bears the ISI mark, it means that it meets the standards set by the Indian Standards Institution. However as the economy grew, the BIS Act was introduced to strengthen laws for both consumers and sellers.


Manufacturers can apply for the mark at the nearest BIS office. A BIS officer then visits the factory to test the samples. If the standards meet all guidelines and pass all tests, the manufacturer will grant the license.
