What is BIS ISI Mark Certification?
The ISI Mark is India's most recognized conformity mark for industrial, electrical, chemical, construction, and consumer goods. Regulated under the Bureau of Indian Standards Act (Scheme-I), it guarantees that a product complies with rigorous Indian Quality Standards (IS Specifications).
The Government of India has issued Quality Control Orders (QCOs) making ISI mark mandatory for hundreds of critical product categories. Operating or selling without an ISI license on notified items attracts strict legal penalties and confiscation of consignments at customs.
Domestic Manufacturers

FMCS (Foreign Manufacturers)
Mandatory statutory scheme for overseas manufacturing plants exporting regulated goods to India. Requires nomination of an Authorized Indian Representative (AIR), overseas physical factory audit by designated BIS delegation, and submission of performance bank guarantee (PBG).
