HSN Code for Medicines and Pharmaceuticals

Most finished medicines sit under heading 3004 of the Customs Tariff, but "HSN code for medicine" has no single answer. Pharmaceutical products are spread across Chapter 30 for prepared medicaments, Chapters 28 and 29 for bulk drugs and APIs, Chapter 90 for medical instruments and devices, and a handful of other headings for gloves, reagents and supplements. Which code applies depends on what the product is, how far it has been formulated, and how it is packed — not on the fact that a chemist sells it.

Where medicines sit in the tariff

The Harmonised System classifies goods by what they are and how far they have been processed. For pharmaceuticals, that produces a clear progression: a chemical compound is a chemical, a prepared medicament is a pharmaceutical product, and an instrument used to deliver or monitor treatment is an instrument. If you have not worked with the chapter, heading and sub-heading structure before, our explainer on how HSN codes work covers the mechanics first.

Chapter 30 heading by heading

Chapter 30 has only six headings, which makes it one of the shorter chapters in the tariff. Almost all of a pharmacy's stock falls into two of them, 3003 and 3004.

Heading 3006 is a closed list: a product belongs there only if the chapter notes name it. A first-aid kit goes in 3006 as a kit, even though its bandages, scissors and antiseptic would each be classified somewhere else if sold separately. Condoms, which people often expect to find next to chemical contraceptives, are rubber articles under 4014.

3003 versus 3004: the dosage-form test

The dividing line between the two main medicine headings is presentation, not ingredients. Heading 3004 covers medicaments put up in measured doses — a tablet, a capsule, a pre-filled syringe, an ampoule, a transdermal patch — or in forms or packings for retail sale, such as a bottle of syrup or a tube of ointment. Heading 3003 covers the same kind of medicament when it is not yet in either form: a bulk granulation, a drum of suspension or a batch of mixed powder sold to another manufacturer to fill and pack.

Heading 3003 also needs two or more constituents mixed together. A single unmixed product in bulk is usually still a chemical in Chapter 28 or 29. Heading 3004 takes both mixed and unmixed products, so a single-molecule tablet is 3004.

Veterinary medicines follow the same test. A dosed or retail-packed veterinary medicament is 3004, the same heading as a human one.

Bulk drugs, vitamins and AYUSH medicines

APIs and bulk drugs

An active pharmaceutical ingredient on its own is a separate, chemically defined compound, so it is classified in the chemical chapters, mostly Chapter 29 for organic compounds and Chapter 28 for inorganic ones. Chapter 29 has specific headings for several drug families: 2936 for vitamins and provitamins, 2937 for hormones, 2939 for alkaloids and 2941 for antibiotics. Other APIs sit under the heading for their chemical structure. Formulating an API into a dosage form moves the product into Chapter 30. A bulk drug manufacturer and the formulator who buys from it will therefore report different chapters for what is, chemically, the same active ingredient.

Vitamins

Heading 2936 covers vitamins and provitamins, natural or synthetic, whether unmixed or mixed with each other. A vitamin put up as a medicament for treating or preventing a deficiency can move to 3004. A multivitamin sold as a general health supplement usually falls under 2106 instead, as explained below. The ingredient is the same in all three cases.

Ayurvedic, Unani, Siddha and homoeopathic medicines

Traditional-system medicines are medicaments, so they are classified in Chapter 30 on the same dosage-form test as allopathic ones: 3004 when dosed or retail-packed, 3003 when not. The Indian tariff has separate eight-digit lines under both headings for Ayurvedic, Unani, Siddha, homoeopathic and bio-chemic systems. Businesses reporting at eight digits should use those lines rather than a generic "other" line.

Medical devices, diagnostics and consumables

Devices are classified as instruments and appliances, mostly in Chapter 90. Chapter 90 is organised by function, so the question is what the device does.

Diagnostics are the fiddliest group. A reagent on its own, a reagent on a backing such as a test strip, and a complete kit can each classify differently. Rapid tests built on immunological reactions can fall in 3002 rather than 3822. For a new diagnostic SKU, read the heading texts and the chapter notes for 30 and 38 together before settling on a code.

The boundaries that cause disputes

Medicament or food supplement

Chapter 30 expressly excludes foods and beverages such as dietetic, diabetic or fortified foods, food supplements and tonic beverages. Nutraceuticals, protein powders, herbal health drinks and most multivitamin supplements therefore usually fall under 2106 in Chapter 21. That is the same Chapter 21 covered in our guide to HSN codes for food items. Putting a product in capsule form does not make it a medicament. What matters is whether it is made and presented to treat or prevent a specific disease, as opposed to supporting general nutrition. The regulatory route it was licensed under, the label claims and the dosage are the usual evidence.

Medicated or cosmetic

Chapter 30 also excludes preparations of headings 3303 to 3307 even if they have therapeutic or prophylactic properties. A skin cream, shampoo or toothpaste with an active ingredient does not become a medicament for that reason alone. Indian disputes over "medicated" and "Ayurvedic" creams, oils and shampoos have turned on the product's primary purpose: whether it is used to treat an ailment, typically for a limited period, or used routinely to care for or beautify the skin and hair. Composition, label claims, the licence it was manufactured under and how buyers understand the product all feed into that call. The same brand can have one SKU in 3004 and another in 3304 or 3305. Classify each product on its own facts.

Rates, invoicing and GSTR-1

The GST 2.0 rate rationalisation took effect on 22 September 2025. It moved most goods from the old 12% band to 5% and left 5% and 18% as the main slabs. Healthcare was widely reported as one of the sectors that benefited, with reductions on many medicines and medical devices and exemptions for some life-saving drugs. The rate notification works line by line against HSN codes, though, and pharmaceuticals carry many specific entries and exemptions. This post does not give a rate for any individual heading. Before you update a rate master, confirm the current rate for each product on CBIC's GST rate finder at cbic-gst.gov.in. Our overview of the current GST rate slabs explains the slab structure, and the HSN code list with GST rates gives the chapter-level map.

How many HSN digits you print on invoices depends on your aggregate turnover in the preceding financial year. At or below ₹5 crore, you report four digits on B2B invoices. Above it, you report six digits on every invoice. The details are in our guide to HSN digits and turnover thresholds. Four digits leaves little room for error here: 3003, 3004 and 2106 are three different answers for products that can look identical on a pharmacy shelf.

A pharma distributor's item master can run to thousands of SKUs, and GSTR-1's HSN summary validates codes against the current tariff, so errors tend to show up at filing time. Our guide to searching for an HSN code covers the lookup tools. The same distributors buy from many small manufacturers and stockists, and input tax credit depends on those suppliers being active and filing. Checking a supplier's GSTIN and filing history before onboarding takes one call to a GSTIN verification API at ₹0.50 per lookup. For an occasional check, there are five free lookups a day on the GST number search tool.
