Chemicals & Fertilizers GST Framework

Fertilizers — 5% (Concessional)

All fertilizers enjoy concessional 5% GST to support agriculture: urea (46-0-0), DAP (18-46-0), MOP (0-0-60), NPK complexes, SSP, ammonium sulphate, calcium ammonium nitrate, micronutrient mixtures, and specialty fertilizers. Input GST on raw materials (natural gas, phosphoric acid, potash) at 18% creates significant inverted duty — manufacturers eligible for refund.

Pesticides & Agrochemicals — 18%

All crop protection chemicals at 18%: insecticides, fungicides, herbicides, rodenticides, bio-pesticides, plant growth regulators. Key products: glyphosate, chlorpyrifos, imidacloprid, mancozeb, 2,4-D. Pre-GST rate was ~22-24% (excise 12% + VAT 5-12.5%). Post-GST: reduction in effective rate. Industry employs 2 lakh+ workers with ₹54,000 Cr annual revenue.

Organic Chemicals — 18%

Broad category at 18% GST: hydrocarbons, alcohols, phenols, aldehydes, ketones, carboxylic acids, esters, nitrogen-function compounds, organo-sulphur compounds. Key products: methanol, ethanol (industrial), acetic acid, formaldehyde, acetone, benzene, toluene, xylene. These serve as intermediates for pharmaceuticals, agrochemicals, polymers, and specialty chemicals.

Inorganic Chemicals — 18%

Acids, bases, and salts at 18%: sulphuric acid, hydrochloric acid, nitric acid, phosphoric acid, caustic soda, soda ash, chlorine, hydrogen peroxide, titanium dioxide, carbon black. These are foundational industrial chemicals. Exceptions: some specific chemicals for fertilizer manufacture attract 5% or exempt status when supplied directly to fertilizer plants.

Paints, Dyes & Pigments

Paints & varnishes: 18% (reduced from 28% in July 2022 — major relief for construction & automotive). Dyes: 18%. Pigments: 18%. Printing inks: 18%. Artists' colours: 18%. Thinners & solvents: 18%. Putty, fillers: 18%. The 28%→18% reduction on paints was a significant industry win, reducing consumer prices for decorative and industrial paints.

Plastics, Rubber & Explosives

Plastics in primary form (polymers): 18%. Plastic articles: 18%. Rubber (raw/synthetic): 18%. Rubber products: 18%. Tyres: 18% (reduced from 28%). Explosives (industrial): 18%. Detonators: 18%. Fireworks/crackers: 28% (sin category). Matches: 12%. Chemicals for mining (ammonium nitrate fuel oil): 18%. These rates aim to balance industrial use vs revenue.

Frequently Asked Questions

Why are fertilizers at 5% but pesticides at 18%?
Fertilizers receive concessional 5% GST because they are essential agricultural inputs subsidized by the government — keeping GST low reduces farmer cost and subsidy burden. Pesticides at 18% reflect their classification as chemical products (Chapter 38) without the same subsidy framework. Industry has demanded parity at 5% arguing both are essential farm inputs, but the Council hasn't approved due to revenue impact (~₹8,000 Cr from pesticide GST).
What is the inverted duty structure in chemicals?
Major issue: fertilizer output at 5% but input chemicals (natural gas, phosphoric acid, sulphuric acid, ammonia) at 18%. This creates accumulated ITC that manufacturers must claim as refund. Processing time for refund: 60-90 days. Similarly, pharma finished goods at 5%/12% but APIs and intermediates at 18%. Government allows refund of accumulated ITC under Section 54(3) for inverted duty.
When was paint reduced from 28% to 18%?
Paint and varnish GST was reduced from 28% to 18% effective from July 18, 2022 (47th GST Council meeting recommendation). This was a major relief for the ₹70,000 Cr paint industry. The reduction applied to all paints: decorative, industrial, automotive, and marine. Consumer prices dropped by 7-8% post reduction. Companies like Asian Paints, Berger passed on the benefit.
How does GST apply to chemical exports?
All chemical exports are zero-rated under GST — exporters can either: (1) export under bond/LUT without paying IGST and claim ITC refund, or (2) pay IGST on export and claim refund. India's chemical exports: ~$30 billion annually. Key exports: dyes, APIs, pesticides, organic chemicals. Zero-rating ensures Indian chemical manufacturers remain globally competitive without embedded tax cost.
