BIS ISI Certification for Aluminium and Aluminium Alloy Products in India: Standards, Process & Requirements

Aluminium's combination of light weight, corrosion resistance and workability has made it indispensable across construction, electrical, packaging, and even aerospace applications — and BIS has responded with one of its most actively revised Quality Control Orders. The Aluminium and Aluminium Alloy Products (Quality Control) Order, 2023 (S.O. 4241(E), dated 25 September 2023) has been amended five times since, most recently in March 2026, reflecting how quickly this category is being refined. It notifies 17 Indian Standards spanning wrought bars, sheets, tubes, wire, rivet stock, composite panels and specialised forgings.

For aluminium extruders, rolling mills and fabricators, staying current with this fast-moving QCO is itself a compliance task. This guide lists all 17 IS standards, explains what BIS certification verifies for aluminium products, and walks through the 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 Aluminium and Aluminium Alloy Products (Quality Control) Order, 2023 (S.O. 4241(E), dated 25 September 2023). Amended by the Amendment Order, 2024 (S.O. 1512(E), 22 March 2024), the 2024 Order (S.O. 4696(E), 28 October 2024), the 2025 Order (S.O. 2021(E), 6 May 2025) with Corrigendum (S.O. 2682(E) & 2683(E), 16 June 2025), and the 2026 Order (S.O. 1319(E), 13 March 2026).

📜 All 17 IS Standards Covered Under This QCO

The Aluminium and Aluminium Alloy Products (Quality Control) Order notifies the following 17 Indian Standards, spanning irrigation tubes, general engineering bars/plates/sheets/wire, electrical-grade products, pharmaceutical foil, composite panels and aerospace forgings:

⚙ What BIS ISI Certification Verifies

BIS testing for aluminium products evaluates chemical composition against the specified alloy grade, mechanical properties (tensile strength, elongation, hardness) appropriate to the temper condition, dimensional tolerances, and — for specialised applications — additional requirements such as electrical conductivity (for electrical-grade wire and bars under IS 5082 and IS 2067) or aerospace-grade forging integrity (IS 7902). Composite panels (IS 17682) are additionally tested for bond strength between the aluminium skins and core material.

📋 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

• Certifying against a superseded standard — IS standards and their governing QCOs are periodically amended; always confirm the current in-force version before testing.
• Treating it like CRS self-declaration — Scheme-I requires a factory audit in addition to testing; manufacturers who plan only for lab testing are caught off guard by the audit stage.
• Missing a variant's distinct standard — product ranges spanning multiple IS standards in the same category need a separate licence for each; assuming one licence covers the whole range is a common and costly error.
• 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.
