How to get an ISI mark licence under IS 7285
The licence is granted to the manufacturer for a specific factory and product. Indian factories apply under Scheme-I; overseas factories apply under the Foreign Manufacturers Certification Scheme (FMCS) and must nominate an Authorised Indian Representative.
- Confirm the exact Indian Standard and the varieties to cover
- Get the product tested at a BIS-recognised lab (simplified procedure) or arrange BIS sampling
- Apply on Manak Online with factory, quality-control and test documents
- BIS factory inspection and sample verification
- Grant of licence, then marking with the ISI mark and CM/L number
Timeline. BIS targets 30 days under the simplified procedure (applying with a recent lab test report) and 90 days under the normal procedure. Overseas factories under FMCS typically take around 6 months.
Fees. Application fee ₹1,000 and annual licence fee ₹1,000, inspection charges of ₹7,000 per man-day, testing charges, and an annual minimum marking fee set for each Indian Standard (with concessions for micro and small units).
