The short version
- Alka Industries asked which HSN heading covers its cast iron brackets.
- The brackets are sand-blasted and enamelled without any machining work.
- Gujarat AAR ruled the products belong under HSN Chapter Heading 7325.
- Basic finishing does not turn cast iron items into sanitary ware parts.
In short
Alka Industries asked the Gujarat Authority for Advance Ruling (AAR) how to classify its cast iron brackets under Goods and Services Tax (GST). These brackets are installed in buildings to support ceramic washbasins, commodes, and urinals. The company melts pig iron, casts it in sand moulds, sand-blasts the rough edges, and applies rust-preventive enamel. The core question was whether these basic castings are general iron articles or specialized sanitary ware parts.
What has changed
How it worked before
Manufacturers often assumed that support brackets designed specifically for sanitary items should be classified as sanitary ware parts under Harmonized System of Nomenclature (HSN) 7324. Others treated them as structural iron or general castings, leading to inconsistent tax rates and disputes during audits.
What has changed
In order GUJ/GAAR/R/2018/9, the tax authority decided that unmachined cast iron brackets fall under HSN Chapter Heading 7325 as general cast articles of iron. Because the products only undergo sand blasting and rust-proofing without machining, they remain basic foundry castings. They do not gain the essential character of sanitary ware parts under HSN 7324 merely because they support ceramic items.
Who this affects
Foundries and engineering units in India that manufacture cast iron brackets, clamps, or supports without performing machining work.
An example
A foundry in Rajkot manufactures cast iron wall clamps used to hold heavy drainage pipes. The foundry casts the iron in sand moulds, sand-blasts them, and paints them to stop rust, but does no drilling or lathing. Based on this ruling, the clamps are treated as general cast iron articles under HSN 7325 rather than specialized pipe fittings.
What you should do
Review your production steps to confirm whether your iron castings undergo machining or only basic cleaning and painting. Note that an advance ruling binds only the business that applied for it and its local tax office. If you want legal certainty for your own business, you should file a separate advance ruling application.
If you do nothing
If you classify unmachined castings under the wrong HSN code, tax officers may reclassify your goods during a GST audit. This can trigger demands for unpaid tax, interest, and penalties. Applying the wrong classification can also lead to disputes over input tax credit claimed by your buyers.

The ruling in detail
Authority for Advance Ruling
M/s. Alka Industries
GUJ/GAAR/R/2018/9 dated 9.04.2018 · Gujarat
Questions before the authority
- Whether the article manufactured by the applicant fall under Chapter Heading 7308, 7325 or 7326 of the HSN or any other heading ?
Facts
The applicant manufactures cast iron brackets and clamps used in the building construction industry as support structures for hanging ceramic washbasins, commodes, and urinals. The manufacturing process involves melting pig iron and scrap in a cupola furnace, pouring molten iron into sand moulds to obtain rough cast iron castings, sand blasting for cleaning, and applying enamel to prevent rust. The applicant does not perform any machining operations on the cast products.
Ruling
| Question | What the authority ruled |
|---|---|
| Classification of cast iron brackets and clamps | Chapter Heading 7325 Unmachined cast iron articles |
The Authority for Advance Ruling held that the cast iron brackets and clamps manufactured by the applicant fall under **Chapter Heading 7325**. As the castings undergo only cleaning and rust prevention without machining, they remain products of the casting industry and have not acquired the essential character of parts of sanitary ware.
Reasoning
The Authority referred to Explanation (iii) and (iv) of Notification No. 1/2017-Central Tax (Rate) dated 28.06.2017 and Chapter Note 1 to Chapter 73 of the First Schedule to the Customs Tariff Act, 1975, defining 'cast iron'. Chapter Heading 7325 covers all cast articles of iron or steel, not elsewhere specified or included. Because the brackets and clamps are merely sand-blasted and enamelled without any machining process, they cannot be held to have acquired the essential character of parts of sanitary ware under Heading 7324, and therefore remain classifiable under **Chapter Heading 7325**.
Provisions relied on
- Section 97(2)(a) of the CGST Act, 2017
- Notification No. 1/2017-Central Tax (Rate) dated 28.06.2017
- Chapter Note 1 to Chapter 73 of the Customs Tariff Act, 1975
- Chapter Heading 7325
For the practitioner
This ruling establishes that cast iron support articles like brackets and clamps that undergo only basic finishing such as sand blasting and rust-proofing without **further machining** are classifiable under **Chapter Heading 7325** as general cast articles. They are not treated as parts of sanitary ware under CETH 7324 merely because they support ceramic sanitary items.
