What Is BIS ISI Mark Certification?
ISI Mark Certification is a product certification issued by the Bureau of Indian Standards under Scheme I of the BIS (Conformity Assessment) Regulations, 2018. The ISI Mark shows that a product meets the relevant Indian Standard (IS). It helps customers identify products that have been certified for compliance with the applicable quality and safety requirements. Manufacturers can use the ISI Mark only after obtaining a valid BIS licence for the covered product.
For example, manufacturers producing certain electrical products, cement and other regulated industrial goods may need ISI Mark Certification, depending on the applicable Indian Standard and government notification.
Is ISI Mark Certification Mandatory in Delhi?

Under Section 16 of the BIS Act, 2016, the government can make compliance with Indian Standards compulsory for specified products. However, not every product requires ISI Mark Certification. Manufacturers should check the latest BIS compulsory certification list before applying.
