When you are investing in steel for building your home, shop, or commercial project, reading TMT bar certification and Marking labels correctly is extremely important.
Why?
Because every original branded TMT bar has specific embossed markings and certification codes that confirm its quality, grade, manufacturing standard, and authenticity.
But unfortunately, in many markets — especially in smaller towns — fake / duplicate TMT bars are sold using similar-looking ribs and colors to confuse buyers.
👉 If you don’t know how to verify certification & quality marks,
you might end up buying low-quality TMT bars that can risk your entire construction.
This guide will help you learn:
✔️ How to identify an original TMT bar
✔️ Where to check ISI mark, grade, and batch number
✔️ How to read TATA TISCON / SAIL SeQR / Shyam Steel markings
✔️ What certification documents you must ask for
✔️ Common frauds used in the market
✔️ Checklist before purchasing TMT bars
What is Embossed Marking on TMT Bars?
Every branded TMT bar contains permanent markings on its outer ribs.
Example:
| TATA TISCON 550SD | 12MM | BILLET MADE | BIS CERTIFIED |
These markings communicate:
| Information on Bar | Meaning |
|---|---|
| Brand Name (TATA TISCON / SAIL SeQR / SHYAM STEEL) | Confirms manufacturer |
| Grade (Fe500, Fe500D, 550SD, Fe550D) | Strength + ductility level |
| Diameter (8mm / 10mm / 12mm / 16mm / 20mm / etc.) | Bar size |
| ISI / BIS Standard Code (IS 1786:2008) | Government-approved quality |
| Heat / Batch Number | Traceability to factory batch |
| Manufacturing method (BILLET) | Ensures purity of steel used |
How to Read the Material Test Certificate (MTC)
Whenever you buy branded steel, ask for the MTC (Mill Test Certificate).
It proves:
- Chemical composition
- Tensile strength
- Yield strength
- Elongation % (D Grade = higher ductility = earthquake resistant)
| Parameter | Ideal for Home Construction |
|---|---|
| Carbon % | Low (prevents brittleness) |
| Sulphur & Phosphorus | Must be within BIS limit |
| Yield Strength | Fe500D or Fe550D preferred |
| Elongation (%) | Higher value means flexibility |
If supplier cannot give MTC → Don’t buy.

Difference Between Original vs Duplicate TMT Bars
| Feature | Original Branded Bar | Duplicate / Local Bar |
|---|---|---|
| Proper embossed brand name | ✅ Yes | ❌ Often missing / uneven |
| ISI / BIS license number | ✅ Proper | ❌ Fake / not traceable |
| MTC certification | ✅ Always provided | ❌ Never available |
| Weight accuracy | ✅ Within tolerance | ❌ Usually underweight |
| Corrosion resistance | ✅ High | ❌ Very low |
Warning Signs of Fake TMT Bars
❌ No embossed branding
❌ No ISI mark
❌ Inconsistent rib pattern
❌ Weight is significantly lower than standard
Lower weight = manufacturer cheating
→ Less steel = weaker foundation
