HSN Code for SS Pipes: Everything You Need to Know for Seamless Procurement

When it comes to industrial sourcing, government tenders or even routine invoicing, one code can make a big difference: the HSN code. For stainless steel (SS) pipes, getting the right HSN classification is crucial for tax compliance, smooth documentation, and successful procurement. In this guide, we will learn exactly what the HSN code for SS pipes is, how it is different for every pipe type, and why it matters.

What is an HSN Code?

HSN (Harmonized System of Nomenclature) is an internationally accepted system developed by the World Customs Organization (WCO) for classifying goods systematically. In India, it’s used under the Goods and Services Tax (GST) regime to always apply correct tax rates on different products.

An incorrect HSN code could actually lead to a lot of delays in tender applications, penalties during audits, or even rejections in procurement processes. That’s why every serious buyer or supplier must understand beforehand how to use it properly.

Standard HSN Codes for Stainless Steel Pipes

Stainless steel pipes fall under Chapter 73 of the HSN classification — "Articles of iron or steel."

Here are the main HSN codes relevant to SS pipes:

1. 73044100

Description: Seamless stainless steel pipes and tubes

Usage: Usually used in high-pressure, high-temperature applications like boilers, heat exchangers, and industrial fluid transport.

2. 73044900

Description: Other steel tubes and pipes (welded, not seamless)

Usage: For general construction, water pipelines, structural applications, and lower-pressure use cases.

3. 73064000

Description: Tubes, pipes, and hollow profiles (welded), of circular cross-section

Usage: Often used in architectural structures, automotive parts, and fabrication work.

How to Choose the Correct SS Pipes HSN Code?

While all the codes mentioned apply to stainless steel pipes, choosing the correct one depends on:

• Pipe type: Seamless vs. welded
• Application: Structural, fluid transport, decorative, etc.
• Manufacturing method
• Product form: Tubes, circular sections, square profiles, etc.

Quick Tip: Seamless = 73044100, Welded = 73044900 or 73064000.

If you’re responding to tenders, most government departments specify the required HSN code in the procurement document. Make sure your product listing or invoice matches it exactly.

You should even make sure to always verify with your tax consultant if you're supplying pipes for a specific industry (like petrochemical, pharma, etc.), as classification might change.

Why Is the HSN Code Important in Stainless Steel Pipe Procurement

Using the correct SS pipes HSN code helps with:

• Correct GST rate application (usually 18% for stainless steel pipes)
• Faster invoicing and e-way bill generation
• Accurate tender bidding (especially for GeM or public sector orders)
• Smooth audits and compliance with government tax regulations
• Export documentation and international trade

If you are bidding on some projects from Indian Railways, PSU oil & gas companies, or large infra EPC players, misclassification can kill your bid in the worst case before it even starts.

This code is applicable whether you're importing, exporting, or conducting domestic trade involving stainless steel pipes.

Correct use of this HSN code is essential when filing GST returns or generating e-invoices for SS pipe prices and orders.

GST Rate on Stainless Steel Pipes

Most stainless steel pipes—whether seamless or welded—attract a GST rate of 18%. However, for buyers working in special economic zones or government-backed projects, exemptions or differential rates may apply.
