No More Cheap Tempered Screen Protectors For Mobiles: Govt Makes Mandatory BIS Norms from April 2027

Smartphone buyers in India will soon say goodbye to brittle, sub-standard screen guards as the Centre makes Bureau of Indian Standards (BIS) certification compulsory for all glass screen protectors sold or imported in the country starting April 1, 2027.

Under a notification issued on September 21, 2026, by the Ministry of Electronics and Information Technology (MeitY), glass screen protectors have been added to the Compulsory Registration Order under entry 66. The move mandates that every glass guard must strictly conform to Indian Standard IS 19348:2025 before hitting store shelves or e-commerce platforms.

Real Screen Protection Instead of Marketing Gimmicks

For everyday consumers, the new regulation shifts the smartphone accessory market from unverified seller claims to lab-tested durability.

Buying cheap road-side tempered glass often leaves devices vulnerable to cracked displays during minor drops. Under IS 19348:2025, certified protectors must pass strict laboratory drop and impact tests, meeting minimum surface compression (500 MPa) and bending strength (200 MPa) benchmarks. Buyers get guaranteed impact resistance rather than relying on misleading "11D" or "100D" retail labels.

Protection From Sharp Glass Shards and Injuries

Low-quality tempered glass typically shatters into razor-sharp splinters upon impact, posing a risk of finger cuts to users.

The mandatory standard enforces anti-shatter and fragmentation testing. If a certified screen protector breaks, the glass is required to disintegrate into dull, safe fragments held together by an underlying adhesive film, protecting both the user's hands and the underlying phone display.

Uncompromised Display Clarity and Touch Response

Cheap screen guards frequently dull display brightness, create rainbow patterns, or leave permanent adhesive bubbles that ruin touch sensitivity.

The BIS framework mandates a minimum light clarity threshold of 89% for standard clear glass and 59% for privacy-tinted guards. The guidelines also penalize manufacturing defects like pinholes, air pockets, or uneven adhesive layers, ensuring full screen visibility and smooth touch responsiveness.

What Buyers Should Expect at Checkout

Consumers will begin seeing official BIS certification marks on accessory packaging ahead of the April 2027 enforcement deadline.

While the additional compliance testing may slightly raise the baseline cost of budget screen guards, buyers gain verified scratch resistance against keys and coins, resistance to sweat and cleaning chemicals, and actual shock absorption for expensive phone displays. Uncertified, unbranded glass guards will be completely removed from physical shops and online marketplaces
