Bricks HSN Code: Understanding HSN Classifications for Bricks
Bricks are basic building materials used in houses, boundary walls, factories and many other structures. Common types include red clay bricks, fly ash bricks and cement bricks and blocks.
To use the bricks HSN code correctly and charge GST without mistakes, traders, builders and brick manufacturers need to know how different bricks are classified under HSN and which GST rates generally apply after the changes from 22 September 2025.
What Is the Bricks HSN Code?
Under GST, most building bricks are classified in the chapter that covers ceramic products and cement based products. Ordinary burnt clay bricks usually fall in the ceramic bricks heading, while many cement and fly ash bricks are grouped in headings for cement articles or other building blocks.
There is no single HSN code for every type of brick. Red clay bricks, fly ash bricks and cement concrete blocks can follow different headings depending on composition and how the product is described in trade.
In day to day billing, many businesses decide one HSN family for common building bricks and another HSN family for cement based blocks and special bricks. They then manage size and strength grades through their own item codes under these HSN families.
Key Bricks HSN Codes and GST Rates after 22 September 2025
| HSN Code | Product Description | Product Type or Variant | GST Rate |
|---|---|---|---|
| 6904 | Ceramic building bricks, flooring blocks and similar articles | Red clay building bricks and common burnt clay bricks | 5% |
| 6815 | Articles of cement, concrete or artificial stone | Fly ash bricks and blocks used for walling | 5% |
| 6810 | Pre cast articles of cement, concrete or artificial stone | Solid and hollow cement blocks and heavy duty paver blocks | 18% |
| 2523 | Cement | Cement used as input for making cement bricks and blocks | 18% |
| 2505 | Natural sands of all kinds | River sand and manufactured sand used with bricks | 5% |
HSN Code for Fly Ash Bricks, Red Bricks, and Cement Bricks
Red bricks made from clay and burnt in kilns are generally treated as ceramic building bricks. They normally fall under the ceramic bricks heading which covers common building bricks and similar articles used in walls and partitions.
Fly ash bricks are made from fly ash mixed with cement and other binders and then moulded and cured. In trade and in many notifications they are treated as a type of building block. For GST purposes they are often placed in the cement or artificial stone article headings that cover blocks and bricks made with cement binders.
Cement bricks and concrete blocks are also grouped in the same cement article or pre cast article headings. Heavy duty pavers, kerb stones and other moulded cement items for roads and landscaping normally share this HSN family but can carry a higher GST rate than basic walling bricks.
Because classification depends on composition and use, businesses should ensure that the item description in their software clearly says red clay bricks, fly ash bricks or cement blocks so that the correct HSN family can be mapped consistently.
GST on Bricks and HSN Code Classification
Under the three slab GST structure that applies from 22 September 2025, basic building materials that support housing and infrastructure such as common bricks are generally kept in the lower 5% slab. This helps keep construction costs under control.
This is why red clay building bricks and fly ash bricks used in normal walling often attract 5% GST under the relevant brick or cement article HSN codes, subject to the detailed conditions in the notifications. In some specific cases the GST rate may vary depending on the type of project or value of the supply.
Many pre cast cement articles such as heavy duty paver blocks and other specialised cement items remain in the standard 18% slab under their cement article HSN codes. Here the higher rate reflects their use in more specialised infrastructure or industrial applications.
For correct billing, builders merchants and brick manufacturers map each type of brick in their accounting software to the right HSN family such as ceramic bricks, fly ash bricks or cement blocks and then set the GST rate at 5% or 18% as applicable. Invoices then show the HSN code, brick type, quantity and GST clearly so that buyers can claim input tax credit correctly.
When they file GST returns, outward supplies are reported HSN wise. If sales of red bricks, fly ash bricks, cement blocks and related inputs like cement and sand are recorded under the correct HSN codes and GST rates, it becomes easier to match returns with purchase data and e way bills and to avoid classification disputes.
Conclusion
The bricks HSN code framework places red clay bricks, fly ash bricks and cement bricks or blocks in different headings based on their composition and how they are supplied. Basic building bricks for walling are usually kept in a lower GST slab, while specialised cement articles can fall in the standard slab.
By linking each brick product to the correct HSN family and applying the correct GST rate of 5% or 18% in invoices and returns, traders and manufacturers can keep construction billing accurate, support smoother input tax credit claims and reduce the risk of penalties for wrong classification.
