Many fertilizers under Chapter 31 commonly attract 5% GST, but agricultural inputs do not have one universal rate. Micronutrients, soil conditioners, bio-inputs, pesticides, chemicals and machinery may classify differently. Composition, intended use and the exact tariff entry—not the word ‘fertilizer’ on a label—control.
Use the rule effective on the transaction date
This guide is a decision aid. GST rates, exemptions, valuation rules and portal procedures can change through notifications and circulars. Match the exact supply, HSN or SAC, parties, place of supply and invoice date against the current official material.
Do not file from a headline rate alone. Preserve the notification, classification working and transaction documents supporting the treatment selected.
Product classification
Collect the chemical composition, nutrient percentages, manufacturing process, intended use, packaging and regulatory registration. Determine whether the product is a fertilizer, separate chemically defined compound, plant-growth regulator, pesticide or soil conditioner.
Rate decision
Many Chapter 31 fertilizer entries are listed at 5%, but a broad agricultural-use claim is insufficient. Verify the live HSN entry and any concessional notification for mixtures, micronutrients and specialty products.

Subsidy and taxable value
Section 15 excludes subsidies directly linked to price when provided by Central or State Governments, while non-government subsidies directly linked to price can enter value. Map who receives the subsidy and how it affects the invoice.
Input tax credit and inversion
Manufacturers and dealers may claim eligible input credit subject to normal rules. Where inputs carry a higher rate than output fertilizer, inverted-duty refund eligibility and exclusions should be tested under current notifications.
Dealer and manufacturer records
Maintain licences or registrations under applicable fertilizer-control laws, batch and composition records, purchase invoices, HSN master, subsidy reconciliation, e-way bills and GST returns.
Common classification errors
Do not classify pesticides, growth promoters, bio-stimulants, farm machinery or every micronutrient as 5% fertilizer without reviewing the tariff, product standards and current circulars.

Request GST supportFrequently asked questions
Is GST on all fertilizers 5%?
No. Many Chapter 31 fertilizers attract 5%, but exact product classification controls.
Are pesticides taxed as fertilizers?
No. Pesticides generally classify separately and may have a different rate.
Is government subsidy part of GST value?
A qualifying Central or State Government subsidy directly linked to price is excluded under section 15.
Can fertilizer dealers claim ITC?
Potentially yes, subject to normal eligibility and documentation rules.
Can an inverted-duty refund be claimed?
Possibly, but current exclusions and notification conditions must be checked.
Does agricultural use decide HSN?
No. Composition and tariff wording remain essential.
