BIS ISI Certification for Gypsum Based Building Materials in India: Standards, Process & Requirements

Gypsum based building materials — plaster boards, ceiling tiles and reinforced panels — have become a construction-industry staple for false ceilings, partition walls and interior finishing across India's residential and commercial building boom. Recognising this growth, BIS notified the Gypsum based Building Materials (Quality Control) Order, 2024 (S.O. 1153(E), dated 6 March 2024), bringing 4 Indian Standards under mandatory ISI certification.

For manufacturers and importers of gypsum boards and panels, this guide lists all 4 notified IS standards, explains what BIS certification verifies, and walks through the ISI licensing process, documentation, timeline and common pitfalls.

🎯 What Is BIS ISI (Scheme-I) Certification?

BIS Scheme-I is the classical Indian Standards Institution (ISI) mark scheme — India's original and most rigorous product certification route. Unlike the self-declaration model used under CRS for electronics, Scheme-I certification requires the manufacturer to hold a BIS licence granted only after laboratory testing and a physical BIS audit of the factory's manufacturing process and quality control system. The ISI mark on a product is a direct assurance that both the product and the process producing it meet the notified Indian Standard.

📄 The Governing Quality Control Order

This category is notified under the Gypsum based Building Materials (Quality Control) Order, 2024 (S.O. 1153(E), dated 6 March 2024). Corrected by Corrigendum S.O. 2007(E) dated 14 May 2024, and amended by S.O. 5058(E) dated 25 November 2024. Import and purchase exemption orders (S.O. 775(E) and S.O. 776(E)) were both issued on 13 February 2026.

📜 All 4 IS Standards Covered Under This QCO

The Gypsum based Building Materials (Quality Control) Order notifies the following 4 Indian Standards, covering plain, coated/laminated and reinforced gypsum plaster boards plus glass fibre reinforced gypsum panels:

⚙ What BIS ISI Certification Verifies

BIS testing for gypsum building materials evaluates board thickness and dimensional tolerance, breaking load/flexural strength, surface hardness, water absorption, and fire-resistance characteristics appropriate to the board type. Reinforced boards and glass fibre reinforced panels are additionally tested for reinforcement integrity and impact resistance, since these grades are specified for higher structural-demand applications.

📋 Step-by-Step: BIS ISI (Scheme-I) Licensing Process

Scheme-I is a test-and-audit certification, more rigorous than the self-declaration route used for CRS-scheme electronics. The sequence is:

1. Identify the applicable IS standard(s)Confirm which of the notified Indian Standards under this QCO apply to your exact product variant and specification.
2. Test at a BIS-recognised laboratorySubmit representative samples for testing against the applicable IS standard. The test report is the foundation of the ISI licence application.
3. Prepare documentationCompile factory details, quality control records, product technical data, and — for foreign manufacturers — the Authorised Indian Representative (AIR) nomination under FMCS.
4. File the online applicationSubmit the application on the BIS Manak Online portal with the test report, factory details, and supporting documents.
5. Factory auditUnlike the CRS self-declaration route, Scheme-I (ISI) certification involves a physical BIS assessment of the manufacturing unit and its quality control system.
6. Grant of licence and ISI markBIS reviews the application and audit findings and grants the licence with a unique licence number, allowing use of the ISI mark on the product.
7. Surveillance, renewal and market samplingLicensees remain under periodic BIS surveillance, including market sample testing, and must renew the licence on schedule.

📂 Documents Required

A complete file at the outset shortens both the review and audit stages. You will typically need:

• Test report from a BIS-recognised laboratory against the applicable IS standard
• Factory registration, business incorporation and address proof
• Product technical specifications, drawings and bill of materials
• In-house quality control and testing facility details
• Manufacturing process flow chart and machinery list
• Trademark / brand authorisation documents
• For foreign manufacturers: Authorised Indian Representative (AIR) nomination under FMCS
• Marking / label artwork showing the IS standard and ISI licence number
• Authorised signatory details and application declarations

⏱ Timeline & Renewal

Because Scheme-I combines laboratory testing with a factory audit, timelines run longer than the self-declaration CRS route. Once granted, the BIS ISI licence remains subject to ongoing surveillance, including unannounced market sampling, and must be renewed on schedule to stay valid.

⚠ Common Mistakes That Delay ISI Licensing

• Assuming one licence covers all board types — plain, laminated and reinforced gypsum boards are separate IS standards under this QCO; each product line needs its own testing and licence.
• Overlooking the May 2024 Corrigendum — this QCO was corrected shortly after notification; applications based on the original, uncorrected text can be rejected.
• Missing glass fibre reinforced panels as a separate category — IS 17400 is distinct from the IS 2095 board series and has its own testing requirements.
• Foreign manufacturers skipping AIR appointment — an Authorised Indian Representative is required under FMCS before a foreign manufacturer's application can proceed.
• Letting surveillance and renewal lapse — an expired or surveillance-failed licence stops the ISI mark from being used, even mid-production run.
