BIS Certification for Indicating Bolts

You have used an indicating bolt every time you have locked a public toilet cubicle and seen the little window flip from green to red, or from "vacant" to "engaged." That small visual indicator is the entire reason this product exists as its own category - it is not just a latch, it is a latch that communicates occupancy to the person waiting outside. It saves the awkwardness of rattling a locked door and is now a standard expectation in any well-run public washroom.

Because these fittings live in high-traffic public facilities and get operated thousands of times, reliability is everything. A latch that jams, fails to show the right status, or wears out quickly creates both inconvenience and a genuine privacy concern, which is exactly the kind of everyday-quality issue compulsory certification is meant to address.

BIS testing for indicating bolts covers dimensional accuracy, the strength and durability of the latch components, the smooth and reliable operation of the locking and indicating mechanism, and finish quality. The indicating action in particular is scrutinised, since a latch that locks but does not reliably show the correct status defeats the purpose of choosing an indicating bolt over a plain one.

Manufacturers producing indicating bolts for sale in India - typically suppliers to the sanitaryware, washroom-fitting and commercial hardware sectors - need this BIS licence in their own name. The order's standard exemptions apply: export-only manufacturing, product imported only as part of a finished assembly, and small Udyam-registered micro units below specified limits, all detailed on our main fasteners page.

The path you take depends entirely on where your factory is. If you manufacture in India, the process runs through BIS's standard product certification route - sample testing, factory documentation and a factory inspection before the licence is issued. We have laid out every step on our BIS Certification for Indian Manufacturers page.

If your factory sits outside India, you will go through the Foreign Manufacturers Certification Scheme, which adds an Authorized Indian Representative and typically an overseas factory audit. The full breakdown is on our FMCS guide for foreign manufacturers.

Fasteners are a deceptively tricky category - 19 products, overlapping standards, easy-to-miss exemptions and a demanding factory audit. We work across the entire fasteners QCO, not as a general firm dabbling, but as a team that knows this product family inside out and prepares every document to exact BIS specification so your file keeps moving - for manufacturers in India and around the world.
