TMT Steel Bar HSN Code & GST Rate

The HSN code for most TMT steel bars is 72142090 in India. TMT bars are generally classified under HSN Heading 7214, which covers certain bars and rods of iron or non-alloy steel.

For common ribbed or deformed TMT reinforcement bars, the relevant subheading is 721420, and the applicable Indian tariff item is generally 72142090.

TMT steel bars under this classification generally attract 18% GST.

What Is the HSN Code for TMT Steel Bars?

The commonly applicable HSN code for TMT steel bars is:

72142090 — Other bars and rods containing indentations, ribs, grooves or other deformations produced during rolling

The classification hierarchy is:

• 72 – Iron and steel

• 7214 – Other bars and rods of iron or non-alloy steel

• 721420 – Bars and rods with indentations, ribs, grooves or other deformations

• 72142090 – Other

This classification fits the common ribbed/deformed construction of TMT reinforcement bars.

TMT Steel Bar HSN Code – Quick Summary

CBIC places bars and rods of iron or non-alloy steel under HSN 7213 to 7215 in the 18% GST slab.

TMT Steel Bar HSN Code Details

TMT bars are classified based on their material and ribbed/deformed surface.

For ordinary TMT reinforcement bars used in construction, 72142090 is generally the relevant tariff item rather than the spring-steel classification.

HSN Codes for Different Types of Steel Bars and Rods

The HSN can vary depending on the form, material and manufacturing process.

TMT bars should therefore not be classified solely by the word “steel.” The material type and physical form matter.

GST Rate on TMT Steel Bars

TMT steel bars under HSN 7214 generally attract 18% GST.

For an applicable intra-state sale:

• 9% CGST

• 9% SGST

For an applicable inter-state sale:

• 18% IGST

CBIC currently lists HSN 7213 to 7215 — all bars and rods of iron or non-alloy steel — at 18% GST.

Example

If TMT bars have a taxable value of ₹1,00,000:

• Taxable value: ₹1,00,000

• GST @ 18%: ₹18,000

• Total invoice value: ₹1,18,000

For an applicable intra-state transaction:

• CGST @ 9% = ₹9,000

• SGST @ 9% = ₹9,000

What Is Included Under HSN 7214?

HSN 7214 covers certain bars and rods of iron or non-alloy steel that are not further worked beyond specified manufacturing processes such as:

• Forging

• Hot rolling

• Hot drawing

• Hot extrusion

• Twisting after rolling

Within this heading, 721420 specifically covers bars and rods with ribs, grooves, indentations or other deformations produced during rolling.

That makes it especially relevant to common TMT and reinforcement bars.

How to Choose the Correct HSN Code for TMT Steel Bars

1. Confirm the material

HSN 7214 applies to iron or non-alloy steel.

If the bar is stainless steel or another alloy steel, a different chapter subheading may apply.

2. Check whether the bar is ribbed or deformed

TMT reinforcement bars typically contain ribs or other surface deformations that improve bonding with concrete.

Products with such rolling-produced deformations fall under 721420.

3. Check whether it is spring steel quality

Within 721420:

• 72142010 – Spring steel quality

• 72142090 – Other

Most ordinary construction-grade TMT bars fall under the “other” classification, 72142090.

4. Check whether the product is supplied in coils

Bars and rods supplied in irregularly wound coils may instead fall under Heading 7213, depending on their specifications.

5. Check whether the steel is alloy or stainless

TMT-like bars made from stainless or other alloy steels may fall under headings in Chapter 72 other than 7214.

Use the most specific code that accurately matches the product supplied.

How to Add TMT Steel Bar HSN Code to an Invoice

When creating a GST invoice for TMT steel bars:

1. Enter the item name, such as TMT Steel Bar Fe500.

2. Add the applicable HSN code, generally 72142090 for common qualifying TMT bars.

3. Enter quantity or weight.

4. Add the taxable value.

5. Apply 18% GST.

6. Apply CGST and SGST for an applicable intra-state sale or IGST for an applicable inter-state sale.

7. Include all other mandatory GST invoice details.

The exact classification can depend on the steel grade, alloy content, manufacturing method and physical form. Products made from stainless or other alloy steels may fall under different headings.
