GST on Medicines in India: 2026 Rates, HSN Codes & Impact Guide

The introduction of the Goods and Services Tax (GST) in India has significantly transformed the tax system, affecting various industries, including pharmaceuticals. GST was introduced to create a unified tax structure, replacing multiple indirect taxes like VAT, excise duty, and service tax. This new system simplifies tax compliance but also challenges pharmaceutical businesses to adapt to different GST rates, HSN (Harmonized System of Nomenclature) codes, and regulatory requirements.

This blog explores the new GST on medicines after the 22 September 2025 reform, applicable tax rates, HSN codes, exemptions, and its impact on the pharmaceutical industry.

What is GST on Medicines in India?

GST on medicines refers to the tax levied on pharmaceutical products under the GST regime in India. Unlike the previous taxation system that involved multiple state and central taxes, GST simplified taxation by implementing uniform tax rates across the country. These rates are categorized based on the necessity and purpose of the medicines, ensuring affordability for essential drugs while maintaining government revenue.

What are the GST Rates on Medicines?

Before 2025-26, 4 different rates of GST slabs for medicine existed. Now, the GST structure shifted to mainly 5% and 18% slabs, abolishing the earlier 12% and 28% slabs in many cases. The classification is as follows:

GST Category	Effective Rate	2025-26 Context
Life-saving & critical drugs	0% (exempt)	Includes cancer & rare disease drugs (about 36 specified items).
Most medicines & general drugs	5%	Standard slab for items not in the essential/health list.
Medical equipment & supplies	5% or Nil (item-specific)	Standard slab for items not in the essential/health list.
Non-essential medical goods	18%	Standard slab for items not in essential/health list.

Most medicines shifted to 5% GST (previously many were at 12%). A list of 36 life-saving and critical drugs is now exempt (0% GST). Many medical devices & equipment previously taxed at 18% (or 12%) are now at 5% or nil.

HSN Codes for Pharmaceutical Products

HSN codes are used to classify goods under GST systematically. Pharmaceutical products generally fall under Chapter 30 of the HSN code system. Some commonly used HSN codes are:

• 3002: Human blood, vaccines, antisera, and similar products
• 3003: Medicaments consisting of multiple constituents for therapeutic or prophylactic use (not in retail sale form)
• 3004: Medicaments for therapeutic or prophylactic use (in retail sale form)
• 3006: Pharmaceutical goods such as surgical catgut, blood-grouping reagents, etc.

HSN Codes are now tied to the new slabs: most pharma HSN codes 3003/3004 will fall under nil or 5% instead of 12%, depending on product classification under the updated GST schedule.

Correct classification using HSN codes is essential for compliance and smooth trade operations. Check out the full list of medicines with 0% GST from the GST Exempted Medicine List PDF by MSME Development Institute, Delhi.

Impact of GST on the Pharma Industry

GST reforms, especially the recent one in September 2025, “GST Reform 2.0“, always impact the relevant industry. Let’s understand the aftereffects it had on the pharmaceutical industry:

Positive Impacts of 2025 GST Update

• Simplified Taxation: GST replaces multiple indirect taxes, making tax compliance more manageable.
• ITC: Pharma companies can claim Input Tax Credit (ITC) on GST for raw materials, reducing overall costs.
• Uniform Taxation: Eliminating state-wise tax variations facilitates seamless interstate trade and logistics.

Challenges with 2025 GST Update

• Compliance Burden: Businesses need to adapt to digital GST compliance systems, requiring investments in software and training.
• Pricing Adjustments: Changes in tax rates for different drugs may impact pricing strategies and affordability.

GST Exempted Medicine List in India

The Indian government has exempted certain medicines from the Goods and Services Tax (GST) to make essential healthcare affordable. These exemptions typically apply to life-saving drugs, vaccines, and medications used to treat critical illnesses. The GST-exempted medicine list includes:

How to Calculate GST on Medicines in India?

Pharmaceutical businesses must follow a structured approach to accurately determine the Goods and Services Tax (GST) applicable to medicines. Proper GST classification ensures compliance with tax regulations and avoids penalties. Here are the key steps to calculate GST on medicines:

1. Identify the Product

Before calculating GST, it is essential to determine the type, usage, and composition of the medicine. The classification depends on whether the product falls under:

• Bulk drugs or APIs (Active Pharmaceutical Ingredients)
• Formulated medicines (tablets, syrups, injections, etc.)
• Healthcare products or nutraceuticals

2. Refer to Official GST Notifications

The Indian government frequently updates GST rates on medicines. Businesses should check the latest GST rate schedules issued by the Central Board of Indirect Taxes and Customs (CBIC) to ensure they apply the correct rate.

New GST on medicines rates include:

a. 0 % GST – Fully GST-free essentials

Certain specified life-saving and critical medicines are completely exempt (0 % GST). These include many expensive cancer, rare disease, and chronic illness drugs that were previously taxed at 12 % or 5 %.

b. 5 % GST – Standard rate for most medicines

Almost all other medicines, whether allopathic, ayurvedic, homeopathic, Unani, or Siddha, now attract a uniform 5 % GST. This includes prescription drugs, general pharmaceuticals, vaccines, diagnostic kits, and most medical consumables that were earlier taxed at 12 % or 18 %.

c. 5 % GST – Nutraceuticals & supplements

Health supplements, vitamins, nutraceuticals, and the like, which previously attracted 18 % (or higher under earlier slabs), have also been brought down to 5 % under the reform.

3. Use Authorized HSN Directories

Medicines are classified under Harmonized System of Nomenclature (HSN) codes, which help determine the applicable GST rate. Official HSN directories provide standardized codes for pharmaceutical products. Standard HSN codes for medicines include:

• HSN 3003 – Bulk drugs and formulations without brand names.
• HSN 3004 – Formulated medicines with specific therapeutic properties.

4. Calculate the GST Amount

Once the correct GST rate is identified, businesses can calculate the tax using the formula:

GST Amount = (Price of Medicine×GST Rate​/100)

For example, if a medicine costs ₹1,000 and falls under the 5% GST slab, the GST amount will be: (1000×5/100)=₹50

Total price after GST = ₹1,000 + ₹50 = ₹1,050

5. Seek Professional Guidance

Pharmaceutical businesses should consult tax professionals or GST consultants to ensure accurate GST calculation and compliance with regulations. This helps in:

• Correct classification of medicines.
• Understanding exemptions and special tax rates.
• Resolving disputes related to HSN codes and GST rates.

GST Compliance for Pharma Businesses

Pharmaceutical companies must follow GST compliance regulations, including:

• GST Registration is mandatory for businesses exceeding the prescribed turnover limit.
• Businesses must file regular GST returns (GSTR-1, GSTR-3B) and comply with e-invoicing norms.
• Companies must maintain records of tax invoices, ITC claims, and HSN code classifications.

Conclusion

The implementation of the Goods and Services Tax (GST) has transformed the pharmaceutical industry by simplifying indirect taxation. Previously, businesses dealt with a fragmented tax system, including various state-specific taxes like VAT and excise duties, which created administrative burdens. GST consolidates these taxes into one unified system, streamlining the process and eliminating the cascading effect that led to price increases and inefficiencies.
