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.
