The ISI mark is the most recognisable certification symbol in Indian manufacturing, but few buyers know exactly what it verifies or how to check whether it's genuine. Here's what it means and how to confirm it.

What the ISI Mark Actually Certifies

The ISI mark is issued by the Bureau of Indian Standards (BIS) and confirms that a product has been tested and certified as compliant with the relevant Indian Standard. For safety footwear, this is IS 15298 (Part 2), covering toe protection, sole properties and construction quality.

Crucially, the mark isn't a one-time approval. Manufacturers must hold an active BIS license tied to their specific factory and product line, which is subject to periodic renewal and surveillance audits by BIS.

What Information Appears Alongside the Mark

A genuine ISI marking on safety footwear is typically accompanied by the BIS license number and the relevant IS standard number (IS 15298:2016 Part 2), either stamped or moulded directly onto the product — not just printed on a hangtag or box that can be swapped.

How to Verify an ISI Mark Is Genuine

1. Locate the BIS license number on the product and search it on the official BIS licensee database to confirm it's active and registered to that manufacturer.
2. Check that the mark is moulded or stamped into the footwear itself, since counterfeit products often print the mark only on removable packaging.
3. Cross-check the product model number against the model listed on the manufacturer's BIS certificate — a valid license for one model doesn't cover a different unlisted model.
4. If sourcing at scale, request a copy of the test certificate from the manufacturer's BIS-recognised testing lab.

Why Counterfeit ISI Marks Are a Real Risk

Because the ISI mark carries weight in tenders and B2B procurement, some manufacturers print it without holding a valid license. Footwear with a fake or expired ISI mark may not actually meet the toe protection or sole performance standards it claims to, putting workers at real risk during an actual workplace incident.

Why It Matters for Tenders

Government, PSU, Railway and large industrial tenders almost always require valid ISI/BIS certification as a mandatory technical qualifier. A supplier who cannot produce a matching, verifiable BIS license is typically disqualified outright, regardless of price.
