In today’s growing market, counterfeit products often carry unauthorized ISI marks that look genuine but fail to meet the necessary safety norms. Verifying the CML number online through the BIS website or the BIS CARE mobile app helps you instantly confirm whether a product is truly BIS certified or not. This verification process not only assures authenticity but also safeguards your health, safety, and investment by preventing the purchase of non-compliant or illegal products.
The format remains consistent across all certified products, whether they are electrical appliances, building materials, electronics, or consumer goods. The “CM/L” stands for Certification Mark License, while the digits represent the unique license number issued to the manufacturer.
A genuine BIS marking on an electrical iron may look like this:
ISI Mark Logo
IS 302 (Part 2/Sec 9): 2009
CM/L-9512550215
Many manufacturers and consumers often get confused between the BIS R Number and the BIS CML Number. Although both numbers are issued by the Bureau of Indian Standards (BIS), they represent two completely different certification schemes — the Compulsory Registration Scheme (CRS) and the ISI Mark Certification Scheme.
