Zinc Sulphate Heptahydrate

Zinc Sulphate Heptahydrate

Zinc sulphate heptahydrate is a key zinc source for fertilizers, animal feed, and industrial processes. It corrects zinc deficiency in soils and crops, improving yield, grain quality, and stress tolerance.

In feed, it supports enzyme function, immunity, and growth in livestock when used at controlled levels. High solubility and crystalline form make it easy to dissolve for foliar sprays, fertigation, and premix manufacturing.

Sr. No. Description Specification
1 Purity 89% (industrial fertilizer grade) and higher grades available
2 Chemical Formula ZnSO₄·7H₂O
3 Form White crystalline powder
4 Country of origin India
5 Quantities 25 kg bags and bulk bags for large agricultural/industrial users
  • White crystals with a density of about 2.07 g/cm³ and high water solubility.​
  • Provides about 22–23% zinc in heptahydrate form.
  • Slightly acidic aqueous solutions.
  • Efflorescent; may lose water and cake when exposed to heat and dry air.
  • Zinc fertilizer in soil and foliar applications for cereals, pulses, fruits, and vegetables.
  • Feed-grade zinc source in animal nutrition premixes (with appropriate regulatory compliance).
  • Mordant and auxiliary in dyeing, plating, and other industrial processes.
  • Ingredient in certain wood preservatives and specialty chemical formulations.
  • Feed and fertilizer grades are manufactured with controlled impurities and particle size.

  • Dust and solutions can irritate eyes, skin, and the respiratory tract; ingesting large amounts may cause stomach upset.

  • Use gloves, goggles, and a dust mask; avoid generating aerosols and fine dust.

  • Prevent uncontrolled discharge to surface waters due to potential aquatic toxicity at high concentrations.
