HSN Code List for Construction Materials 2025 – Cement, Steel, Bricks & Tiles
Whether you’re a contractor managing a large project or an individual building your dream home, navigating GST compliance can be complex. One of the biggest hurdles is correctly identifying HSN codes for your materials. This single detail impacts your invoices, your ability to claim tax credits, and your overall compliance with tax laws. Getting it wrong can lead to unnecessary complications and penalties. This is why having a reliable HSN code list for construction materials is not just helpful—it’s essential for smooth operations. This guide provides a comprehensive list for 2025, helping you stay compliant and manage your finances effectively. We’ll cover everything from the HSN code construction materials India uses for basics like cement and steel to specifics like bricks and tiles, ensuring your business stays on the right side of the law.
What is an HSN Code and Why is it Crucial for Building Materials?
Before we dive into the lists, it’s vital to understand the “what” and “why” behind these codes. The Harmonized System of Nomenclature (HSN) is a globally accepted method of classifying goods for customs and tax purposes. In India, it forms the backbone of the Goods and Services Tax (GST) system, providing a systematic way to identify thousands of different products. For the construction sector, which deals with a vast array of materials, HSN codes bring much-needed uniformity to taxation. They ensure that a specific type of steel bar or cement bag is taxed at the same rate across the entire country, eliminating ambiguity and simplifying trade. This standardization is crucial for maintaining a transparent and efficient tax regime, allowing businesses to operate with clarity and confidence.
Decoding the HSN Code Structure in India
The HSN code used in India is an 8-digit number, which provides a highly detailed classification for goods. This structure can be broken down to understand its logic. The first two digits represent the Chapter, the next two represent the Heading, the following two are the Sub-heading, and the final two digits are the Tariff Item, which offers an even deeper level of classification.
For example, let’s consider a TMT steel bar, a fundamental construction material. It falls under HSN code 7214 20 90.
- 72: Chapter (Iron and steel)
- 14: Heading (Other bars and rods of iron or non-alloy steel)
- 20: Sub-heading (Containing indentations, ribs, grooves, or other deformations produced during the rolling process)
- 90: Tariff Item (Specific classification for other types)
Understanding this structure helps you appreciate how precisely materials are categorized for GST purposes.
The Role of HSN Codes in GST Compliance
The primary role of HSN codes in the GST framework is to determine the correct tax rate for a product. Each HSN code is mapped to a specific GST slab—5%, 12%, 18%, or 28%. When you create a tax invoice, mentioning the correct HSN code is not just good practice; it’s a legal requirement. The Indian government has mandated the declaration of HSN codes on invoices based on a business’s annual aggregate turnover:
- Businesses with an annual turnover of more than ₹5 crore must use a 6-digit HSN code for all their invoices.
- Businesses with an annual turnover of up to ₹5 crore must use a 4-digit HSN code for all their B2B (business-to-business) tax invoices.
Correctly quoting these codes ensures that you charge the right amount of GST, file accurate returns, and enable your buyers to claim Input Tax Credit (ITC) without any issues.
The Cost of Getting it Wrong: Penalties for Incorrect HSN Codes
Using an incorrect HSN code—whether intentionally or by mistake—can have serious financial and legal repercussions. The GST authorities treat such errors as non-compliance, which can lead to several adverse consequences. Firstly, it may result in a tax notice from the department demanding clarification and payment of the differential tax amount if you charged a lower rate. Secondly, penalties can be levied under Section 125 of the CGST Act, which can go up to ₹25,000 for each error. Furthermore, if the wrong code leads to underpayment of tax, you will be liable to pay interest on the shortfall. For the buyer, an incorrect HSN code on an invoice can lead to the rejection of their Input Tax Credit claim, disrupting their cash flow and creating friction in business relationships.

Frequently Asked Questions (FAQs)
1. Is it mandatory to mention HSN codes on all invoices in India?
Yes, it is mandatory, but the number of digits required depends on your annual aggregate turnover.
- Businesses with a turnover exceeding ₹5 crores must mention a 6-digit HSN code on their invoices for all supplies (B2B and B2C).
- Businesses with a turnover up to ₹5 crores must mention a 4-digit HSN code on invoices issued to registered persons (B2B supplies). Mentioning it for B2C supplies is optional for this category.
2. What is the difference between an HSN code and an SAC code?
The distinction is simple:
- HSN (Harmonized System of Nomenclature) codes are used to classify goods. All physical products, like cement, steel, and bricks, fall under HSN codes.
- SAC (Services Accounting Code) codes are used to classify services. For example, construction labor, architectural design services, or plumbing services are categorized using SAC codes.
3. What should I do if the GST rate for a material changes?
The GST Council meets periodically to review and revise tax rates. If a rate changes, you must apply the new rate from the date it becomes effective. To stay updated, you should:
- Follow official notifications from the Central Board of Indirect Taxes and Customs (CBIC).
- Regularly check the official GST Portal for the latest tax rate information.
- Consult with a tax expert to understand the implications of the changes for your business.
4. Where can I find the HSN code for construction labor and services?
As mentioned above, services are classified using SAC codes, not HSN codes. Construction services fall under Chapter 9954 of the SAC code list. For example:
- SAC 9954: This code covers a broad range of general construction services for buildings, civil engineering works, and more.
For specific services like plumbing, painting, or electrical work, there are more detailed SAC codes within this chapter. It is always advisable to consult a professional to identify the exact SAC code applicable to your specific service.
