What we supply
Magnesium sulphate heptahydrate — the salt most people know as Epsom salt — carries both magnesium and sulphur in a water-soluble form, which is why fertiliser blenders and micronutrient formulators buy it in tonnage.
Velora supplies heptahydrate in 50 kg bags and 1 MT jumbo bags. Be clear about which hydrate you want: heptahydrate carries seven waters of crystallisation and the monohydrate only one, so the monohydrate is roughly 17–18% magnesium against roughly 9.8% for heptahydrate. A tonne of one is not a tonne of the other, and the two cannot be compared on headline price.
Grades & packing
These are the formats we most commonly supply. Other grades, packing sizes and pack marking are available — ask at the enquiry stage.
| Product | Formula | Grade | HSN | Packing |
|---|---|---|---|---|
| Magnesium Sulphate | MgSO₄·7H₂O | Heptahydrate, Epsom | 2833 21 00 | 50 kg bag · 1 MT jumbo |
No tested values are published here. The certificate of analysis for the batch actually loaded travels with the despatch documents, and a representative COA and the safety data sheet go out before any commercial discussion.
Applications
Magnesium and sulphur source in NPK blends and micronutrient mixtures, supplied to blenders and formulators.
Magnesium supplement in feed premixes where feed-grade material is specified.
Weighting and finishing agent, and a component of dye baths.
Magnesium source in chemical synthesis, and the reactant with magnesia in magnesium oxysulphate cement and MgO board.
Magnesium dosing where process water needs hardness added back, as in remineralising RO permeate.
Handling & storage
Worth reading before you order rather than after. If any of this is a problem at your site, tell us — it usually changes what we would quote.
Price
Magnesium sulphate is quoted per kg or per tonne, landed. Hydrate form (heptahydrate versus monohydrate), grade — technical, agricultural or feed — crystal size, and bag versus jumbo all move the number, and freight is a large share of the landed cost because the product is heavy and low-value per tonne.
Questions
It is quoted per kg or per tonne, landed. Compare quotes on the same hydrate and the same magnesium content — heptahydrate and monohydrate are not interchangeable on price. Send quantity, grade and delivery point for a written offer.
No. We supply 50 kg bags and 1 MT jumbo bags in bulk to fertiliser blenders, feed millers, dealers and industrial users. Retail packs for direct farm sale are a different trade with its own registration requirements.
Chemically yes — Epsom salt is magnesium sulphate heptahydrate. The difference is grade and certification: pharmaceutical and food grades are made and tested to their own standards, and we supply technical and agricultural material.
We quote per bag or per tonne, landed, once we know the grade and quantity. Because the product is heavy and low-value per tonne, freight to your pin code is a large part of the number.
Magnesium sulphate is a specified fertiliser under the Fertiliser (Control) Order, 1985, so both sides of the trade carry obligations. We sell on a technical and industrial basis against a written specification; if the material is being bought for fertiliser use, say so at the enquiry stage so the grade, documentation and dealer registration position for your state are settled before the order is placed. We do not sell FCO-labelled product for direct sale to farmers.
The HSN code for magnesium sulphate is 2833 21 00 (Sulphates of magnesium). This is the line for chemically manufactured magnesium sulphate. Natural magnesium sulphates — kieserite and epsomite — are classified separately under 2530 20 00, which attracts a different GST rate, so the correct code depends on how the material was produced, not on the hydrate. Confirm the heading with your own tax adviser. Source: the Indian customs tariff as listed in the GST HSN directory, checked September 2026.
Documentation
The transport classification depends on the grade and concentration quoted and is confirmed on the safety data sheet for that material before despatch.

| Representative COA | A producer’s representative certificate of analysis for the grade you specify, obtained at enquiry stage so your QC can assess magnesium sulphate against your own specification | Before commercial terms |

| Technical data sheet | Handling, storage and materials-of-construction guidance | On request |
| TREM card | Carried where the grade quoted is classified as a dangerous good | With the consignment |
We do not publish blank certificates to download. A certificate of analysis belongs to a batch, so a generic one tells you nothing about the material on your vehicle — and the safety data sheet is the producer’s document for the grade actually quoted. Ask and both are emailed, usually the same working day.
