BIS Registration for Glass Screen Protectors IS 19348 — Complete Registration Guide

• IS 19348:2025 is the Indian Standard that governs quality, safety, and labelling of tempered glass screen protectors sold or imported in India.
• Registration is processed under BIS's Compulsory Registration Scheme (CRS), based on lab testing plus self-declaration of conformity — no factory audit is normally needed.
• Selling glass screen protectors without a valid BIS CRS registration can lead to seizure of stock, monetary penalties, and blocked customs clearance.
• A CRS registration is typically valid for 2 years from grant, renewable for further terms up to 5 years, subject to fresh test reports before expiry.

Introduction

BIS Registration for Glass Screen Protectors under IS 19348 is the mandatory registration Indian and foreign manufacturers, importers, and brand owners need before selling tempered glass screen protectors for mobiles, tablets, laptops, and wearables in India.

It is granted under the BIS Compulsory Registration Scheme (CRS), after the product is tested at a BIS-recognised laboratory for parameters such as dimensional accuracy, optical clarity, surface hardness, and impact and bend strength. Once approved, the manufacturer gets a unique registration (R) number and can use the BIS Standard Mark on the product and packaging. Registration is generally valid for two years and can be renewed. Without it, products can be seized, fined, or held at customs.

What Is IS 19348:2025?

IS 19348:2025 is the Indian Standard published by the Bureau of Indian Standards specifically for tempered glass screen protectors used on the display surfaces of electronic devices — smartphones, tablets, laptops, and smartwatches. Before this standard, glass screen protectors were sold in India with almost no uniform quality benchmark, which meant users regularly encountered products that scratched easily, distorted colours, reduced touch sensitivity, or shattered into sharp, injury-causing shards on impact.

The standard fixes this gap by setting measurable requirements for how a tempered glass protector should perform — from how accurately it is cut to fit a device, to how much light it lets through, to how much pressure it can withstand before cracking. For manufacturers and importers, IS 19348:2025 is now the reference standard used when applying for BIS registration for this product category, and compliance is verified through BIS-recognized laboratory testing rather than a factory-floor inspection alone.

Why BIS Registration Matters for Glass Screen Protectors

For Manufacturers and Importers

• Legal market access — a valid BIS registration is what allows the product to be legally manufactured, imported, and sold across India.
• Smoother customs clearance — registered products move through import checks without the delays that non-compliant shipments face.
• Marketplace eligibility — major e-commerce platforms increasingly ask sellers to declare BIS compliance for regulated electronics accessories.
• Stronger brand credibility — a BIS mark signals tested, standard-compliant quality to retailers, distributors, and buyers.

For Consumers

• Assurance that the protector meets a minimum bar for scratch resistance, clarity, and drop protection.
• Lower risk of the glass shattering into sharp fragments that can cut hands or damage the device screen underneath.
• Confidence that packaging discloses genuine manufacturer, batch, and thickness details rather than unverifiable claims.

Who Needs BIS Registration for Glass Screen Protectors Under IS 19348

Registration is required by anyone who places tempered glass screen protectors into the Indian market under their own brand or as the manufacturing entity. This includes:

• Domestic manufacturers producing screen protectors within India.
• Importers and brand owners who source finished screen protectors from overseas factories and sell them under an Indian brand.
• Foreign manufacturers exporting to India, who must appoint an Authorized Indian Representative (AIR) to file and manage the registration on their behalf.
• OEM/private-label sellers who get products manufactured on contract but sell under their own brand name.

Traders and pure resellers who do not own the brand or the manufacturing unit are generally not eligible to apply directly — registration sits with the manufacturer or the brand owner holding proper authorisation.

Key Quality Parameters Covered Under IS 19348

The standard lays down objective, testable criteria rather than vague quality claims. A BIS-recognised lab checks the sample against benchmarks that broadly cover:

• Dimensional accuracy — The cut must align precisely with the device model, without gaps, overhang, or misalignment around cutouts (camera, speaker, sensors).
• Optical clarity — Light transmission must stay within the defined range so screen visibility and colour accuracy are not compromised; privacy-glass variants have a separate, lower threshold since they're designed to restrict side-angle viewing.
• Surface and edge quality — The panel must be free of bubbles, cracks, pinholes, rough or unfinished edges, and visible processing defects.
• Mechanical strength — Minimum surface compression and bending strength thresholds so the glass can absorb everyday drops and knocks without shattering.
• Adhesion performance — The adhesive layer must bond evenly to the screen without bubbling, peeling, or leaving residue.
• Labelling and packaging — Manufacturer name, batch number, thickness, manufacturing date, and the BIS mark with registration number must be clearly and permanently displayed.

Note: exact numerical thresholds (light transmission percentages, compression and bend strength values) are defined in the full text of IS 19348:2025. Applicants should procure the official standard document from the BIS online standards store rather than relying on secondary summaries, since test houses will assess samples strictly against the published clauses.

Eligibility Checklist For BIS Registration for Glass Screen Protectors

• Confirm you are the manufacturer, the brand owner with manufacturer authorization, or a foreign manufacturer with an appointed AIR.
• Have a registered business entity with a valid PAN and GST registration.
• Finalize the exact product variants (models, sizes, thickness, normal vs privacy glass) you intend to register together.
• Identify a BIS-recognized or NABL-accredited laboratory that tests to IS 19348:2025.
• Prepare product samples in the final packaging and labelling format the market version will use.

Step-by-Step BIS Registration Process for Glass Screen Protectors

• Identify the correct standard: Confirm your product is covered under IS 19348:2025 and note the exact model variants you're registering.
• Get samples tested: Send representative samples to a BIS-recognized or NABL-accredited laboratory for testing against IS 19348:2025 parameters.
• Prepare documentation: Compile business, technical, and legal documents, including the lab test report.
• Register on the CRS portal: Create an account on the BIS CRS portal and file the application with all supporting documents.
• BIS review: BIS officials verify the test report, technical documents, and manufacturer/brand details for compliance.
• Grant of registration: On successful verification, BIS issues a registration certificate with a unique R-number, which must appear on the product and its packaging.
• Start compliant marking and sale: Apply the BIS Standard Mark and registration number to every unit before it enters the market.

BIS Registration Fees — Indicative Structure

These figures are indicative and drawn from published BIS/CRS fee patterns for electronics-category registrations; they are subject to periodic revision by BIS. Always verify the current fee notification on the official BIS CRS portal (www.crsbis.in) or bis.gov.in before budgeting, since fee circulars are updated from time to time.

Validity, Renewal & Compliance Timeline For Glass Screen Protectors

Because BIS periodically updates registration and renewal circulars — including validity periods, fee slabs, and portal procedures — it's worth checking the latest official notification PDF published on bis.gov.in or crsbis.in before you file, rather than relying only on secondary sources. If BIS issues a fresh notification or Quality Control Order (QCO) specifically for IS 19348:2025, the validity and enforcement timeline in that PDF will supersede general CRS timelines described above.

Marking & Labelling Requirements For Glass Screen Protectors

• The BIS Standard Mark and unique registration (R) number must be printed clearly and permanently on the product or its packaging, or both.
• Marking must remain legible and durable — it shouldn't rub off, fade, or peel under normal handling.
• Packaging must disclose manufacturer name and address, batch number, glass thickness, and date of manufacture.
• Any change in label design, company details, or manufacturing address requires a modification application to BIS before the new packaging is used.

Consequences of Selling Without BIS Registration

• Seizure and confiscation of unregistered stock by enforcement authorities.
• Monetary penalties and legal proceedings under the BIS Act, 2016.
• Import shipments held or rejected at customs without valid registration proof.
• Listing removal or restriction on e-commerce marketplaces that require BIS compliance declarations.
• Long-term damage to brand trust once non-compliance becomes publicly known.

Common Mistakes Applicants Should Avoid

• Submitting test reports from a lab that isn't BIS-recognized for this standard — such reports are rejected outright.
• Registering a product description that doesn't exactly match what's sold — mismatched thickness, model, or glass type can trigger a compliance flag.
• Waiting until the last month before expiry to start renewal — fresh testing and document review take time.
• Changing packaging or manufacturing address without filing the required modification application first.
• Assuming one registration automatically covers every future model variant without formal inclusion.
