Fabrication Work HSN Code
Fabrication Work HSN Code
Fabrication work hsn code is 9988 with a GST Rate of 18% in India under the name of General fabrication work. If you are looking for specific HSN codes for sheet metal, SS or aluminium fabrication, we have provided the table below.
Fabrication work, in simple terms, is all about taking raw metal and turning it into something useful. It could be cutting, bending, welding, or assembling metal sheets, pipes, or beams to make products or structures. Think of everything from a steel gate to a custom-made kitchen rack, or even large structural frames used in construction.
Under GST, fabrication work is treated as a service when someone is paid to create or assemble these metal products. It is not about selling metal, GST is applied to the service of transforming that metal into a finished product. That’s where the Fabrication Work HSN code comes into play. Every type of fabrication work has a code, which tells the tax authorities exactly what kind of service you provided

What is an HSN Code?
- HSN (Harmonized System of Nomenclature) is an internationally recognized method used to classify goods and services for taxation. In the context of fabrication work, the HSN code applies to the manufacturing, assembly, or repair of metal products.
- Since fabrication involves providing a service rather than just selling goods, it is classified under SAC (Services Accounting Code) for GST purposes.
- Using the correct HSN or SAC code makes sure you have proper taxation, compliance, and eligibility for input tax credit, making it easier for businesses to manage their accounts and avoid disputes with tax authorities.
Assigning the right HSN coder for fabrication work is crucial for several reasons:
- GST Compliance: The GST regime covers all the goods and services. Failing to comply with the right HSN code will lead to penalties, fines and even legal scrutiny.
- Input Tax Credit (ITC): Businesses can claim ITC only when purchases and services are reported under the correct HSN code. Using the wrong code may result in being denied ITC.
- Transparency in Trade: HSN codes provide clarity on the type of product or service being supplied, providing clear trade documentation, especially for international transactions.
- Industry Standardization: Using standardized codes like MS fabrication HSN code, SS fabrication HSN code, or steel fabrication HSN code ensures uniformity across industries.
Simplified Accounting: Proper HSN classification simplifies maintaining records, file GST returns, and calculate tax liabilities accurately.

MS Fabrication HSN Code
Mild steel (MS) is one of the most commonly used materials in fabrication because it’s affordable and quite versatile. MS fabrication usually involves shaping the steel into beams, sheets, pipes, and other components. Using the MS fabrication HSN code makes sure that GST is applied correctly and consistently on these products and services. Businesses involved in mild steel fabrication should use HSN codes like 998873 or 7308, depending on whether it is a product manufacturing service or a structural fabrication.
Steel Fabrication HSN Code
Steel fabrication covers both carbon steel and alloy steel. This process includes cutting, rolling, welding, and assembling steel into structural components or machinery parts. Using the steel fabrication HSN code helps businesses maintain proper tax compliance while also standardizing invoicing and accounting practices. The most common codes applied here include 7308, 7326, and 998873, with an 18% GST rate applicable across most services.
SS Fabrication HSN Code
Stainless steel (SS) fabrication is really important in industries that need corrosion-resistant components, like kitchen equipment, medical tools, or chemical machinery. Using the SS fabrication HSN code helps make sure these high-value fabrication services are taxed correctly and reported well. Like other metal fabrication services, SS fabrication typically falls under HSN 998873 or similar structural codes, attracting an 18% GST rate.
How to Choose Right HSN Code for Fabrication Work
Choosing the correct HSN code depends on several factors, including the type of product, the manufacturing process, and the nature of the service. Here’s a simple way to decide:
- Identify the type of metal: Whether it’s mild steel (MS), stainless steel (SS), or alloy steel, each metal type may have a different HSN code.
- Determine the type of manufacturing: Understand whether the work involves manufacturing, fabrication, or repair services.
- Verify GST details: Check credible sites like the ClearTax portal or the official GST portal to make sure you have the correct GST rates and HSN codes.
Consult professionals: If you are in doubt, contact GST practitioners or tax consultants for accurate proper classification and compliance.
Conclusion
If you want to set up a fabrication business in India, understanding fabrication work HSN code is essential. Accurate HSN classification ensures GST compliance, makes accounting a bit simpler, and helps businesses claim input tax credit properly. Be it MS fabrication, SS fabrication, or just steel fabrication in general, using the right HSN code usually helps standardize taxation, cut down errors, and keeps operations running smooth without interruptions.
With the latest 2025 update, most fabrication work falls under the 18% GST rate, so it is important for businesses to keep an eye on HSN code changes. Following these codes properly helps companies stay compliant, makes operations easier, and lets them focus more on growth in the metal fabrication industry.
