Magnesium Sulphate (Epsom Salt) Supplier, Exporter & Global Wholesaler
Searching for a dependable Magnesium Sulphate supplier or exporter? You are exactly where you need to be.
PAU Chemicals is an India-based global supplier and exporter of Magnesium Sulphate Heptahydrate — Epsom Salt — in technical and cosmetic grades, for fertiliser blenders and personal care buyers.
Magnesium Sulphate is the most soluble and readily available source of magnesium and sulphur, two nutrients that limit crop yield more often than growers realise. Both are supplied in immediately plant-available form.
PAU Chemicals supplies agricultural and cosmetic grades in crystal and powder form, each with its own documentation.
Magnesium deficiency shows as yellowing between the veins of older leaves while the veins stay green. If you are seeing that pattern, magnesium sulphate corrects it faster than any soil amendment because it is immediately available.

What is Magnesium Sulphate, and what is it called locally?
It is magnesium sulphate heptahydrate, known worldwide as Epsom salt. In Indian trade it is often simply called magnesium sulphate or MgSO₄.
What is it used for?
Correcting magnesium deficiency in crops, bath salts and spa products, pharmaceutical preparations, animal feed supplementation, brewing water treatment and textile processing.
How do I know if my crop needs magnesium?
The classic sign is yellowing between the veins of older leaves while the veins stay green. Magnesium sulphate corrects it quickly because it is immediately available to the plant.
Can I use agricultural grade for bath salts?
No. Bath, cosmetic and pharmaceutical uses require the corresponding grade with controlled heavy metals and arsenic. Specify the grade at enquiry.
What is the difference between heptahydrate and monohydrate?
The heptahydrate carries seven waters and around 16% MgO, dissolving readily in cold water. The monohydrate is more concentrated at around 27% MgO and is preferred for blended dry fertilisers.
How should it be stored, and what is the shelf life?
Sealed bags in a cool, dry place. It is mildly hygroscopic and cakes in humid storage; caking does not affect assay but slows dissolution.
Which ports and Incoterms do you ship on, and how long does delivery take?
Hazira and Nhava Sheva on EXW, FOB, C&F and CIF terms, typically 3 to 4 weeks, shipping as general cargo. Export MOQ is 1 FCL.
