We get some version of this question in almost every first call: "Do I need BIS or FMCS?" The honest answer is that it depends entirely on where the factory is, not on the product.
The short version
- If the factory is located in India, domestic BIS certification applies.
- If the factory is located outside India and the product is sold in the Indian market, FMCS (Foreign Manufacturers Certification Scheme) applies instead.
Same product, same Indian Standard — different scheme, purely based on manufacturing location.
Why FMCS takes longer
FMCS involves an extra layer that domestic BIS doesn't: an Authorized Indian Representative (AIR). This is a person or entity based in India who takes on regulatory responsibility on the foreign manufacturer's behalf — receiving communication from BIS, coordinating the factory audit logistics, and being the point of contact for market surveillance.
Setting up the AIR arrangement correctly, and scheduling an in-person or virtual factory audit across time zones, is usually what stretches an FMCS filing to 8–12 weeks versus the 2–8 weeks typical of a straightforward domestic filing.
A common mistake
Some overseas manufacturers assume that because their product already carries CE marking, UL listing, or another international certification, BIS/FMCS is a formality. It isn't — Indian Standards frequently test different parameters, or the same parameter to a different threshold, than the international standards a factory may already comply with. Existing certifications can speed up parts of the documentation, but they don't replace the Indian Standard test requirements.
If you're not sure which applies to you
Tell us where the factory is and what the product is, and we'll confirm the scheme, the AIR requirement (if any), and a realistic timeline before anything is filed.
