ISI Mark (BIS) Certification Process

The ISI Mark is granted by the Bureau of Indian Standards (BIS). BIS reviews your application, inspects the factory, and draws product samples for testing against the relevant Indian Standard. On success, a licence to use the ISI Mark is issued, maintained through surveillance and periodic testing.

Avantcert prepares your factory, quality controls and test evidence so the BIS inspection and testing pass first time.
