Introduction

For domestic manufacturers in India, maintaining product quality and meeting regulatory requirements is important before selling the products in the market. BIS ISI Mark Certification is one of the mandatory requirements before the products can be sold or distributed in India.

The Bureau of Indian Standards (BIS) is India's national standards body. It develops and publishes Indian Standards and operates certification schemes to ensure that products meet specified quality, safety, and performance requirements. The ISI Mark is one of the most recognized product conformity symbols in India. Domestic manufacturers with the notified products need to obtain the relevant BIS licence before using the ISI Mark on them.

In this blog, we will explain the BIS ISI Mark Certification process for domestic manufacturers, documents required, benefits, costs, and other important points.

Understanding BIS ISI Certification

BIS ISI Certification is a mandatory product certification under which BIS verifies whether a product included in the BIS applicable product list conforms to the prescribed Indian Standard. Once the manufacturer meets the required conditions and receives the BIS licence, they can use the ISI Mark on the notified product according to BIS requirements for sale in India.

The ISI Mark indicates that the product has been assessed against the applicable Indian Standard. It helps customers identify products that comply with specified quality and safety requirements. 

Who can apply for BIS ISI Mark Certification?

All manufacturers (Indian and Foreign) manufacturing a notified product covered under the applicable BIS product list can generally apply for the relevant BIS licence. They are required to obtain the BIS ISI mark certificate before the sale, export, and import of notified products in the Indian market. The exact requirements can vary depending on the product and its applicable Indian Standard.

Note: Indian Importers and Traders cannot apply directly for the certification. They can request a copy of the license from the actual manufacturer for the import and sale of the notified products in the Indian market.
