India Mandates BIS Certification for Smartphone Screen Protectors Starting April 2027

The Government of India has officially brought smartphone screen guards and tempered glass protectors under its mandatory quality compliance regime. According to a Gazette notification issued by the Ministry of Electronics and Information Technology (MeitY), all screen protectors manufactured, imported, or sold within the country must comply with Bureau of Indian Standards (BIS) specifications under IS 19348:2025 starting April 1, 2027.

The order amends the Electronics and Information Technology Goods (Requirement of Compulsory Registration) Order, 2021, inserting screen protectors at Serial No. 66 of its regulated product schedule. The policy intervention aims to bring quality assurance to an estimated ₹12,000 to ₹16,000 crore market that sells upwards of 500 million units annually, while weeding out brittle, unbranded imports that fail to provide meaningful display protection.

Inside IS 19348:2025: Tough Benchmarks for Glass and Adhesives

Historically, tempered glass screen guards sold across roadside kiosks, repair stalls, and e-commerce storefronts have operated with zero standardized oversight. Under the newly notified IS 19348:2025 (“Glass Screen Protector – Specification”), every protector must pass rigorous testing at BIS-recognized laboratories:

• Mechanical & Impact Strength: Glass sheets must demonstrate a minimum surface compression strength of 500 MPa and a bending strength of at least 200 MPa, backed by calibrated steel-ball drop tests to simulate accidental drops on hard concrete.
• Optical Transmission & Clarity: Clear tempered glass must guarantee a minimum light transmittance of 89%, while specialized privacy-filter glass must maintain at least 59% transmission without distorting display color reproduction or touch accuracy.
• Shatter Containment: Protectors must feature an integrated anti-shatter film layer to prevent fractured glass shards from detaching and causing personal injury or scratching the underlying smartphone display during a high-impact fall.
• Adhesive Integrity & Surface Defect Limits: Adhesives must adhere uniformly without forming persistent air bubbles, resisting degradation from hand sweat, skin cosmetics, and cleaning alcohol. Batches exhibiting visible pinholes, edge chips, or surface micro-scratches will fail certification.
• Mandatory Packaging Disclosure: Retail packaging must explicitly list the registered manufacturer, batch tracking number, exact glass thickness (in millimeters), and the official BIS registration mark.

Primary Target	Substandard, brittle unbranded imports (primarily from East Asia)

Curbing Substandard Imports and Driving Domestic Manufacturing

A large portion of the tempered glass sold in India consists of unbranded bulk sheets imported at rock-bottom container tariffs, which are subsequently packaged locally without standardized thermal tempering or chemical bath strengthening.

By placing screen protectors under the Compulsory Registration Scheme (CRS), customs authorities will block non-compliant shipments at Indian ports of entry starting April 1, 2027. Foreign and domestic fabricators must register their manufacturing lines with the BIS and submit physical test samples to accredited laboratories.

The move aligns with New Delhi’s broader “Make in India” electronics value-addition roadmap, encouraging domestic accessory brands to invest in local precision cutting, chemical strengthening, and automated adhesive coating facilities, potentially generating thousands of specialized manufacturing jobs.

Consumer Impact: Better Protection vs. Potential Price Hikes

For smartphone users, the mandate delivers long-overdue consumer protection:

• End of Misleading “9H” Marketing: Consumers will no longer have to decipher marketing buzzwords such as “11D Gorilla Tempered” or “Diamond Hardness,” as the BIS certification ensures an audited baseline of impact resistance and touch sensitivity.
• Potential Rise in Street-Corner Pricing: Compliance overhead-including initial lab evaluation costs, factory auditing, and recurring certification fees of around ₹28,000 for a two-year license per SKU-will disproportionately impact hyper-budget sellers. Market analysts anticipate that the ubiquitous ₹49 to ₹99 generic tempered glasses sold at street kiosks may gradually vanish or see prices adjust upward toward the ₹149 to ₹199 range.
• Six-Month Clearance Window: The government has provided a transition grace period running until April 1, 2027, allowing retailers, distributors, and e-commerce warehouses to clear existing non-certified stock without facing immediate seizure or operational disruption.

With smartphone displays becoming increasingly costly to replace-frequently exceeding 30% to 40% of a device’s total purchase value on curved OLED flagships-the introduction of standardized testing guarantees that aftermarket accessories provide genuine drop defense rather than mere cosmetic cover.
