BIS Certificate for Aluminium Alloy Products IS 733

Aluminium alloy product manufacturers must follow Indian legal requirements when they want to sell in this market. BIS certification under IS 733 serves as an important method to reach the Indian market
This guide walks you through everything you need to know—from the technical side of IS 733 to the real-world application process. We’ll also explore the key documents, testing requirements, common pitfalls, and how to ensure your aluminium alloy bars and rods not only meet the standards but get BIS approval the first time around

What does 733 Really Mean

IS 733 is the Indian Standard that governs wrought aluminium and aluminium alloy bars, rods, and sections. This standard is set by the Bureau of Indian Standards (BIS). It outlines the exact physical, mechanical, and chemical characteristics required for these products.

It ensures product consistency and safety—especially in sectors where aluminium is a critical component, like aerospace, transport, construction, and electronics.

Unlike general aluminium grades or standardizations used globally, IS 733 is unique to India’s regulatory ecosystem. That means if you want to market or distribute aluminium products in India, certification under IS 733 is your gateway.

Why BIS Certification is a Non-Negotiable for Aluminium Products

The Government of India has made BIS certification mandatory for aluminium products through Quality Control Orders (QCOs). These QCOs are issued under the Bureau of Indian Standards Act, making it legally binding.

Failing to get certified isn’t just risky—it can halt operations, block shipments, or even attract legal penalties.

On the flip side, a BIS license gives you access to an enormous and quality-sensitive market. Whether you're supplying government contracts or working with major infrastructure companies, being certified boosts your credibility and your business prospects.

The Core Requirements

This certification applies to both domestic and foreign manufacturers of:

  • Wrought aluminium bars
  • Aluminium alloy rods
  • Precision-engineered aluminium sections

If your products fall under this classification and you intend to sell or distribute them in India, certification under IS 733 is mandatory.

It’s important not to confuse IS 733 with other aluminium-related standards like:

  • IS 1285 (for aluminium ingots and castings)
  • IS 5082 (for wrought aluminium and aluminium alloys that are used for electrical applications)

IS 733 has its own separate testing protocols and specifications.

Documents Required

To get started, you’ll need to gather the following documents for submission during the application process:

Document Type Purpose

Factory License

Legal proof of your facility’s operation
Process Flowchart End-to-end description of the manufacturing line
List of Machinery & Equipment In-house production and testing machinery details

Quality Control Manual SOPs for quality assurance and process control

Make sure every document is up-to-date, signed, and properly formatted. Missing even a single document can stall your application.
