BIS Certification for Grey Iron Castings (IS 210:2009): Everything Manufacturers Need to Know
If you've ever held a car engine block, a manhole cover, or a heavy-duty machine part, there's a good chance you were holding grey iron casting. It's one of the most widely used industrial materials in the world — tough, easy to machine, and cost-effective. The name comes from the grey colour you see when the metal breaks, which happens because of the unique graphite flakes inside its structure.
Grey iron castings show up everywhere — in automotive components, water pipes, pumps, machine tools, and construction equipment. India's manufacturing sector depends heavily on this material. And because it's so widely used, the Government of India has made it mandatory for every manufacturer — whether Indian or foreign — to get their products BIS certified before selling in the Indian market.
What Is BIS Certification and Why Does It Matter?
BIS stands for Bureau of Indian Standards — India's national quality watchdog. When a product carries the ISI Mark, it means it has been independently tested and approved against a specific Indian Standard. For grey iron castings, that standard is IS 210:2009.
This is not optional. The Department for Promotion of Industry and Internal Trade (DPIIT), under the Ministry of Commerce and Industry, has made BIS certification mandatory for all grey iron castings sold in India — whether made locally or imported from abroad. The mandate came into full force from February 23, 2024.
No ISI Mark means no legal sale in India. It's that straightforward.
What Does IS 210:2009 Actually Cover?
IS 210:2009 is the Indian Standard written specifically for grey iron castings. It defines what a grey iron casting must look like, how strong it must be, and how it should perform under real-world conditions.
The standard recognises seven grades, each designed for different levels of mechanical stress:
• FG 150 — General-purpose, low-stress components
- FG 200 — Cylinder heads, gearbox housings
- FG 220 — Medium-duty machine parts
- FG 260 — Flywheels, brake drums
- FG 300 — Heavy-duty engine components
- FG 350 — High-stress industrial castings
- FG 400 — Demanding structural and engineering applications
The higher the number, the stronger and more demanding the grade. Each grade has its own requirements for tensile strength, hardness, microstructure, and chemical composition.
Mandatory Tests for BIS Certification (IS 210:2009)
Before a product can earn the ISI mark, it goes through a rigorous series of tests. Here's what BIS inspectors look for:
1. Workmanship and Finish: Is the casting free from visible cracks or surface defects?
2. Freedom from Defects: A thorough check for both internal and external flaws
3. Tensile Test: How much pulling force can the casting handle before breaking?
4. Hardness Test: Measured on the Brinell scale to confirm material consistency
5. Chemical Composition: Analysis of carbon, silicon, manganese, and other key elements
6. Microstructure Examination: Studying the graphite flakes under a microscope to confirm the authentic grey iron structure
7. Transverse Test (if required): Assesses bending strength for specific product types
8. Hydrostatic Test: Checks for leaks under water or fluid pressure, critical for pipes and valves
Only products passing all applicable tests qualify for BIS certification.
Who Needs BIS Certification?
The short answer: everyone who makes or sells grey iron castings in India.
Indian manufacturers must obtain the ISI Mark licence before legally selling their castings in the domestic market. Foreign manufacturers and importers are equally required to be BIS certified — without it, their products simply cannot enter or be sold in India.
BIS Certification Scheme Applicable
1. Certification Type: Product Certification Scheme
2. Scheme: ISI Mark Scheme – Scheme I (Schedule II)
3. Governing Standard: IS 210:2009
4. Marking Requirement: Compulsory ISI logo with unique CM/L license number
5. Mandatory From: February 23, 2024
Timeline for BIS Certification
These are standard timeframes under normal conditions. Delays happen when documentation is incomplete or testing results need re-evaluation. Starting early and getting your paperwork right the first time saves weeks of back-and-forth.
Scope of ISI Certification for IS 210:2009
This Standard Covers:
1. All seven grades of grey iron castings (FG 150 to FG 400)
2. Automotive components — engine blocks, cylinder heads, gearbox housings
3. Industrial machinery — flywheels, brake drums, machine tool bodies
4. Infrastructure products — manhole covers, pipes, valves, pumps
5. Heavy-duty structural and engineering applications
Specifically Excluded:
1. Ductile iron and malleable iron castings (governed by separate standards)
2. Non-ferrous castings
3. Castings not conforming to defined grade specifications
4. Products covered under separate BIS product standards
Benefits of BIS Certification for Grey Iron Casting Manufacturers
1. Market Access: Without the ISI mark, you cannot sell grey iron castings in India
2. Buyer Confidence: The ISI mark is an instant signal that your product has been independently verified
3. Brand Protection: Certification dramatically reduces liability risk from product failures
4. Equal Competition: The same standards apply to every manufacturer — domestic or international
5. Government Project Eligibility: Essential for public infrastructure and procurement tenders
6. Export Facilitation: Builds confidence and credibility in international markets
Consequences of Non-Compliance
Under the BIS Act, 2016, violations carry severe consequences:
1. Market Restriction: Inability to sell or import products in India
2. Goods Seizure: Confiscation of non-certified stock
3. Monetary Penalties: Fines up to ?5,00,000 or five times product value
4. Legal Action: Prosecution under Sections 29–33 of BIS Act
5. E-commerce Delisting: Removal from online marketplaces
6. Brand Reputation Damage: Loss of customer and stakeholder trust
7. Project Disqualification: Exclusion from government and infrastructure projects

Our Frequently Asked Questions
BIS certification for grey iron castings is a mandatory government requirement issued by the Bureau of Indian Standards (BIS) under IS 210:2009. It ensures that grey iron castings sold in India meet defined quality, safety, and performance standards. Products must carry the ISI Mark to be legally sold in the Indian market.
Yes, it is fully mandatory. The DPIIT (Department for Promotion of Industry and Internal Trade), Ministry of Commerce and Industry, Government of India, has made BIS certification compulsory for all grey iron castings — both domestically manufactured and imported — effective February 23, 2024.
The applicable standard is IS 210:2009, established by the Bureau of Indian Standards. It covers all requirements for grey iron castings including grades, mechanical properties, chemical composition, microstructure, and testing methods.
IS 210:2009 defines seven grades based on tensile strength: FG 150, FG 200, FG 220, FG 260, FG 300, FG 350, and FG 400. Each grade is suited for different industrial applications, from general-purpose low-stress components to high-demand structural and engineering parts.
The major tests include Workmanship and Finish, Freedom from Defects, Tensile Test, Hardness Test, Chemical Composition Analysis, Microstructure Examination, Transverse Test (if required), and Hydrostatic Test. All tests must be conducted at a BIS-approved laboratory.
For Indian manufacturers, the standard timeline is approximately 30 days. For foreign manufacturers and importers, the process typically takes around 180 days. Timelines can vary depending on documentation readiness and testing results.
No. Foreign manufacturers must obtain BIS certification under the Foreign Manufacturers Certification Scheme (FMCS) before their products can be imported and sold in India. Without the ISI Mark, grey iron castings cannot legally enter the Indian market.
Selling grey iron castings without the mandatory ISI Mark is a violation of the Quality Control Order issued by DPIIT. It can result in legal penalties, product seizure, and being barred from the Indian market. Compliance is not optional.
