GST Rates & HSN Code for Quartz: A Complete Guide

Businesses operating in natural stones and minerals, including quartz, require full comprehension of Goods and Services Tax (GST) regulations throughout modern commercial environments. The HSN Code for Quartz is particularly important due to quartz's multiple applications in construction, interior design projects, and electronics fabrication, where it enables critical industrial processes.

This complete research investigates GST tax rates and the HSN Code for Quartz classification system to assist manufacturers, traders, exporters, and consumers in better understanding and navigating these regulations.

What is Quartz?

The naturally occurring quartz material exists as silicon dioxide (SiO₂), which makes up the main mineral composition. Human societies utilize quartz from Earth in its various forms because this mineral occurs throughout the planet as its most prevalent mineral form:

Natural Quartz: Used in jewellery, electronics, and scientific instruments.

Engineered Quartz (Quartz Slabs/Quartz Stone): The Engineered Quartz group includes Quartz Slabs/Quartz Stone products that industries widely used for kitchens and architectural uses.

Quartz Sand and Powder: The construction industry, as well as the glassmaking sector and foundry operations, both use quartz sand and quartz powder.

Different types of quartz come under different HSN codes, which correlate to specific GST rates because of their versatile nature. The correct classification of quartz materials remains crucial because it determines compliance with Indian tax rules.

Understanding HSN Code for Quartz

The World Customs Organization (WCO) created the HSN (Harmonized System of Nomenclature) code as an internationally recognized system for good classification. India has established an 8-digit HSN code framework for the GST guidelines to handle goods.

Here's how quartz is categorized under the HSN system:

1. HSN Code 2506 – Quartz (in natural form)

Description: The description includes Quartz (except natural sands) together with quartzite, both in its rough state and cut by sawing or other methods into rectangular blocks or slabs.

Common Usage: Raw quartz, unprocessed quartz blocks used for industrial purposes.

2. HSN Code 250510 – Silica Sands and Quartz Sands

Description: Silica sands and quartz sands, whether or not coloured.

Common Usage: Foundry sand, glassmaking, construction.

3. HSN Code 6810 – Articles of Cement, Concrete, or Artificial Stone (includes engineered quartz)

Description: The classification includes quartz countertops that form part of building construction together with artificial stone articles.

Common Usage: Polished quartz slabs, kitchen and vanity tops, wall panels, etc.

GST Rates on Quartz Products

The GST rates vary based on the classification of quartz under the HSN code. Below is a detailed breakdown:

HSN Code	Description	GST Rate
2506	Natural Quartz and Quartzite	5%
250510	Silica Sands and Quartz Sands	5%
6810	Engineered Quartz (Quartz Slabs/Articles of Artificial Stone)	18%

Detailed GST Insights

Raw Quartz (HSN 2506):

Used primarily in industrial manufacturing processes.

Lower GST rate (5%) due to being a raw mineral.

Quartz Sand (HSN 250510):

Attracts 5% GST as it is used extensively in manufacturing and construction.

Engineered Quartz Products (HSN 6810):

Considered finished or semi-finished goods.

Higher GST rate (18%) to align with processed building materials.

Impact of GST on Quartz Industry

The GST regime brought uniformity and eliminated multiple layers of indirect taxes. However, its impact varies across the quartz value chain.

Advantages:

Streamlined Tax Structure: Clear classification under HSN codes reduces confusion and disputes.

Input Tax Credit (ITC): Businesses can claim ITC on purchases of quartz material, reducing the overall tax burden.

Boost to Exports: Quartz exporters can operate under zero-rated GST with refund eligibility.

Challenges:

Higher Tax on Engineered Quartz: The 18% GST on quartz slabs increases the cost for real estate and interior sectors.

Classification Confusion: Misclassification between natural and engineered quartz can lead to legal issues or penalties.

Compliance Tips for Quartz Dealers and Manufacturers

Correct HSN Code Usage: Ensure invoices and filings use the accurate HSN code corresponding to the type of quartz product.

Maintain Proper Documentation: The records of purchase invoices, together with processing information and sales documentation, must be maintained as evidence to support tax filings.

Understand Input Tax Credit Rules: Use proper understanding of Input Tax Credit rules to maximize effectiveness when using ITC and reduce tax obligations.

Monitor GST Updates: GST Updates Should Be Monitored Through Regular Monitoring Of The Council Notifications For Rate And Classification Modifications.

Quartz GST Scenario: Domestic vs Export

Domestic Trade:

GST is applicable at the prescribed rate depending on product classification.

Registered buyers can avail ITC.

Export of Quartz:

Export is treated as a zero-rated supply.

Exporters can:

Export under bond/LUT (Letter of Undertaking) without paying GST and claim ITC refund.

Pay IGST on export and claim a refund of the same.

This makes exports financially viable and competitive globally.

Examples of GST Classification for Quartz Products

Product	HSN Code	GST Rate	Remarks
Raw Quartz Blocks	2506	5%	No processing involved
Quartz Sand	250510	5%	Used in construction
Engineered Quartz Slabs	6810	18%	Polished and finished surface
Quartz Kitchen Countertop	6810	18%	Processed article of artificial stone
Quartz Powder (Micronized)	2506	5%	If not coated or chemically treated

Conclusion

The successful operation of businesses under GST depends on proper classification and compliance when dealing with quartz rates and HSN codes. Knowledge about GST application for raw quartz and quartz sand, and engineered quartz slabs remains crucial because it allows businesses to set accurate prices and develop tax strategies and function smoothly in their trading activities.

Quick Takeaways:

Use HSN 2506 or 250510 for natural quartz and quartz sands (5% GST).

Use HSN 6810 for processed/engineered quartz products (18% GST).

Exporters benefit from zero-rated GST with refund eligibility.

Always stay updated with GST notifications and changes.

FAQs

Q1: Can I use the same HSN code for both raw and processed quartz?

No. Raw and processed quartz have different HSN codes. Using the wrong code can result in penalties or compliance issues.

Q2: Is there a GST exemption for small quartz miners or suppliers?

GST exemption applies to businesses with aggregate turnover below the threshold limit (₹40 lakhs for goods in most states), but once registered, GST must be charged regardless of business size.
