How to check if a helmet is certified for use in India
Which safety mark is the standard on helmets in India? The ISI mark, governed by IS 4151:2015 for two-wheeler helmets and IS 2925 for industrial and workplace protection, is the only legally mandated
Which safety mark is the standard on helmets in India? The ISI mark, governed by IS 4151:2015 for two-wheeler helmets and IS 2925 for industrial and workplace protection, is the only legally mandated certification for helmets sold in the country. Counterfeit ISI marks are a well-documented and persistent problem: BIS enforcement operations have repeatedly uncovered helmets bearing unauthorised marks that never passed BIS testing. For procurement teams and HSE officers, buying the wrong helmet is not just a compliance failure. It leaves workers unprotected with paperwork that looks correct. A ₹1,000 fine for a rider caught wearing a non-ISI helmet is the least of your problems when you consider the cautionary risk of supplying uncertified PPE across a workforce.
Every certified helmet must carry the ISI mark alongside a valid BIS licence number in the CM/L format. Without both, the helmet is not compliant, regardless of how authentic it looks.
One of the fastest ways to sidestep counterfeit risk is to source from a supplier who already lists BIS licence numbers and certification details on every product page. That is exactly how Safety Online structures its approved helmet range, so procurement teams can verify compliance before placing an order rather than chasing paperwork after delivery.
What the ISI mark actually certifies, and which standard applies to which helmet
The ISI mark is issued by the Bureau of Indian Standards (BIS) and is the only legally mandated certification for helmets sold in India. It is not a voluntary quality badge. Under the Motor Vehicles Act and the Helmet for Riders of Two Wheeler Motor Vehicles (Quality Control) Order, 2020, which came into force on 1 June 2021, riding without an ISI-marked helmet is a punishable offence. Selling non-ISI helmets is banned outright.
IS 4151:2015 for two-wheeler riders
IS 4151:2015 covers protective helmets for everyday motorcycle and scooter riders, not high-speed competition. The standard specifies impact absorption, retention system strength, field of vision, penetration resistance, rigidity, and a maximum helmet mass of 1,500 g. Any helmet sold for road use in India must comply with this standard. Choosing a helmet based on appearance, thickness, or price alone is how compliance gaps start.
IS 2925 for industrial and workplace protection
IS 2925 applies to industrial safety helmets used on construction sites, factory floors, and other occupational settings. IS 2925 is designed to cover falling-object and workplace-impact hazards, not road crash dynamics. The two standards are not interchangeable, and a construction site manager who orders two-wheeler helmets for shopfloor use, or vice versa, is running a non-compliant PPE programme regardless of how many ISI marks are on the products.
How to check which safety mark is standard on a helmet in India: reading the certification markings
Many buyers look for the ISI logo and stop there. The full marking tells a more complete story and is what BIS inspectors and procurement audits check against. Learning to read it takes two minutes and saves considerable trouble later.
What to look for on the helmet itself
A genuine ISI-marked helmet displays three elements together: the ISI logo (the circular BIS mark), the standard reference (IS 4151:2015 for two-wheelers), and a CM/L licence number in the format CM/L-XXXXXXX, where XXXXXXX is a seven-digit number. This marking should be permanently applied, either embossed, laser-etched, or laminated into the helmet shell or inner liner. It should not be a removable sticker. If it lifts at the edge, that is already a red flag.
Decoding the carton and packaging label
The outer carton of a compliant helmet repeats the same CM/L number, the manufacturer's name and address, the standard reference, and the BIS mark. Cross-check that the brand name and model on the box matches what is physically on the helmet. Discrepancies between the carton and the product are a common sign of a non-compliant batch, and BIS enforcement operations have consistently found this pattern in raided stock.
Step-by-step authenticity checks procurement teams can run
This is a repeatable process any HSE officer or procurement manager can apply before approving a helmet supplier or clearing an incoming batch. It works whether you are checking a single helmet at a retail counter or evaluating a bulk shipment of five hundred units.
Step 1: Physical inspection of the mark and CM/L number
Confirm the ISI mark is permanent, not a peel-off label. Locate the CM/L number and note it down exactly as printed. Check that the IS 4151:2015 reference appears alongside the mark. If any of these three elements are missing, stop the process and reject the batch. No exceptions.
Step 2: Verify the licence on BIS CARE
Open the BIS CARE app (available on standard app stores) or the BIS online portal. Select "Verify Licence Details" and enter the CM/L number exactly as printed on the helmet. A valid result returns the manufacturer's registered name and address, the licence status (active, expired, or cancelled), the covered standard, and the brands or models authorised under that licence. This step takes under a minute and is the most reliable verification available.
Step 3: Match the result to the physical product
Confirm that the brand, model, and manufacturer name on the helmet match the BIS CARE result. An active licence for a different brand or a different product category does not validate the helmet in your hand. BIS enforcement data from 2024 to 2025 shows that over 162 helmet-manufacturer licences were cancelled and more than 2,500 non-compliant helmets were seized in Delhi alone, meaning active-looking marks on stock may reference licences that are already cancelled or reassigned.
Red flags that expose a counterfeit ISI mark
Knowing what a genuine mark looks like is a start. Knowing what a fake typically looks like is what saves procurement teams from expensive mistakes. Counterfeit ISI marks follow predictable patterns, and most of them are visible before you even open BIS CARE.
Physical signs the certification is not genuine
The most common indicator is a sticker-based ISI mark that lifts at the edges or can be peeled off cleanly. Other physical red flags include a blurred or uneven CM/L number, a number that does not follow the CM/L-XXXXXXX format, or a standard reference that reads something other than IS 4151:2015 on a two-wheeler helmet. Helmets with missing impact-absorbing foam or unusually light shells are also consistent with the counterfeit patterns BIS has documented in enforcement raids.
When the BIS CARE search raises a concern
If the CM/L number returns no result, an expired licence, or a licence covering a completely different product category, the helmet is non-compliant regardless of how authentic the mark looks. An inactive or cancelled licence means the manufacturer no longer holds BIS approval, even if older batches were once legitimate. BIS enforcement operations have confirmed that some helmets sold on major e-commerce platforms have carried unauthorised ISI marks linked to CM/L numbers that resolve to entirely different product categories.
International marks like ECE, DOT, and SNELL: context for Indian buyers
Many premium helmets carry international certifications alongside or instead of the ISI mark. Procurement teams sourcing imported helmets or reviewing supplier catalogues need to understand what these marks indicate and where they stand legally in India.
How protection levels compare across standards
ECE R22.06 (Europe) is among the more rigorous of the commonly referenced standards. It tests at multiple impact speeds and includes rotational force testing, which measures oblique-impact brain injury risk. IS 4151 does not include explicit rotational impact requirements, placing ECE R22.06 ahead on that specific dimension of real-world crash protection. SNELL is a voluntary, racing-oriented standard that is generally stricter than DOT certification in the United States. DOT (FMVSS 218) is a self-certification standard, meaning no independent pre-approval is required before a manufacturer applies it to a product. IS 4151 sits at a solid baseline and is fit for road use in Indian conditions. ECE R22.06 adds a higher degree of protection specifically for rotational brain injury, which IS 4151 does not explicitly address.
Legal standing in India: why these marks do not replace ISI
A helmet carrying only ECE, DOT, or SNELL certification is not road-legal in India. Enforcement authorities accept the ISI mark under IS 4151:2015 as the sole legal standard for two-wheeler helmets. A helmet with dual marking, for example, ISI plus ECE, is compliant because the ISI mark is present. Buyers importing or recommending premium helmets must still confirm the ISI mark is on the product. No matter how well-regarded the international standard, Indian traffic police and workplace inspectors will only accept an ISI-certified helmet as legally valid.
Where to source BIS-approved helmets with verified certification
Running the BIS CARE check yourself is straightforward, but sourcing from a supplier who does this vetting upfront removes the risk of non-compliant stock entering your workplace entirely. This is the difference between a reactive compliance process and a proactive one, and it matters most during large-scale procurement cycles where a single bad batch affects dozens or hundreds of workers.

The short answer, and the practical next step
Which safety mark is the legal standard on helmets in India? The ISI mark under IS 4151:2015 for two-wheeler riders and IS 2925 for industrial use. A genuine certified helmet shows the ISI mark, the standard reference, and a valid CM/L number that confirms active status when checked in BIS CARE. International marks like ECE R22.06 and DOT add useful context about protection levels, but they do not replace the ISI requirement under Indian law.
For procurement teams and HSE officers, the simplest way to maintain compliance is to work with a supplier who has already done the verification. Browse Safety Online's BIS-approved helmet range, review the certification details on each product page, and contact the team for bulk compliance support. Counterfeit helmets are a documented and persistent problem in the Indian market; verified sourcing is the most reliable way to keep them out of your supply chain.
