Request SDS →Zinc sulfate heptahydrate (CAS 7446-20-0), the hydrated zinc salt of sulfuric acid. It is used as a soil amendment and fertilizer to correct zinc deficiency, as a zinc source in animal feed, and as a zinc-plating bath electrolyte. It also serves as a chemical intermediate and mordant.
Frequently Asked Questions
What is zinc sulfate heptahydrate used for?
Zinc sulfate heptahydrate (CAS 7446-20-0) is used as a soil amendment and fertilizer to correct zinc deficiency, a zinc source in animal feed, a zinc-plating bath electrolyte, and a chemical intermediate and mordant. RawSource supplies it as a bulk agricultural and industrial raw material.
Is zinc sulfate heptahydrate the same as zinc sulfate?
It is the heptahydrate form of zinc sulfate, ZnSO4·7H2O, carrying seven waters of crystallization. It contains the same zinc sulfate but with lower zinc content per gram than the anhydrous or monohydrate forms; specify the hydrate that matches your formulation.
What is zinc sulfate heptahydrate commonly known as?
It is sometimes referred to as white vitriol or zinc vitriol, the hydrated crystalline zinc sulfate (CAS 7446-20-0, formula ZnSO4·7H2O). RawSource identifies material by CAS and assay to avoid ambiguity.
Is zinc sulfate heptahydrate water soluble?
Yes. The heptahydrate is highly water soluble, which suits its use in liquid fertilizers, foliar sprays, feed premix solutions, and plating electrolytes.
What is the HS code for zinc sulfate heptahydrate?
It classifies under HS 2833.29 (sulphates, other, of zinc). Confirm the final tariff classification with your customs broker for the destination, and request a bulk quote with CoA and SDS.
