Potassium Sulphate (SOP) Supplier in Malaysia
- Also known as
- Potassium Sulfate
- K2SO4
- Sulphate of Potash
- Sulfate of Potash
Potassium sulphate supplier for plantation fertiliser, fertigation and industrial buyers in Malaysia. Also spelled potassium sulfate and traded as sulphate of potash, sulfate of potash or SOP (K2SO4), it is a white crystalline salt valued as a chloride-free potash source that also supplies sulphur.
Commercial forms include granular agricultural SOP for broadcast and dry blends, water-soluble powder for fertigation and foliar programmes, and technical crystalline grades for glass and process chemistry. Agricultural material is commonly referenced near 50% K2O; confirm assay and chloride limits against the grade you need.
Agriculture is the main market: SOP is the potash input for chloride-sensitive crops and oil-palm plantation programmes where muriate of potash would add unwanted chloride. Manufacturers use technical grades in glass and related formulations, and laboratory or feed work may call for a defined purity grade.
Send the required form or grade, target specification, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.

Common questions about potassium sulphate
Are potassium sulphate and potassium sulfate the same product?
Yes. Potassium sulphate is the Commonwealth spelling and potassium sulfate is the American spelling of the same salt, K2SO4. Both appear in trade documents; the product is also called sulphate of potash, sulfate of potash or SOP. State the form and grade in the enquiry because granular fertiliser and soluble powder handle differently.
What is SOP or sulphate of potash?
SOP is the fertiliser trade name for potassium sulphate, also written sulphate of potash or sulfate of potash. It is the main chloride-free potash source used where muriate of potash (potassium chloride) would add unwanted chloride. Agricultural SOP is commonly referenced near 50% K2O.
Which form should I request, granular or powder?
Granular agricultural SOP is usual for broadcast and dry fertiliser blends on plantations and field crops. Water-soluble powder is preferred for fertigation, foliar feed and hydroponic dosing. Technical crystalline grades suit glass and industrial process work. Describe the application method with the enquiry.
Why choose potassium sulphate instead of muriate of potash?
Potassium sulphate supplies potassium with sulphur and very low chloride, which suits chloride-sensitive crops and programmes that must limit chloride from KCl. Muriate of potash remains the lower-cost general potash source where chloride is acceptable. State the crop and chloride constraint so the right potash salt can be discussed.
What does 50% K2O mean for agricultural SOP?
Agricultural SOP is commonly described by a market potash equivalent near 50% K2O. It is a commercial reference for fertiliser buyers rather than a guarantee for every lot, so confirm the required K2O, sulphur and impurity limits when requesting a quotation.
What details are needed for a potassium sulphate price enquiry?
Provide the form or grade, application or crop programme, target specification or K2O level, quantity and delivery location. Mention preferred packing and any documents needed so availability, packing and commercial terms can be confirmed with the quotation.
