Potassium sulfate is an inorganic salt used mainly as a chloride-free source of potassium and sulfur in fertilizers and feed premixes.

It is preferred for chloride-sensitive crops, high-value plants, and formulations where low chloride is critical.

In some pharmaceutical and nutraceutical preparations, it can function as a mineral component or buffering salt when high purity is ensured.

Its high stability, low hygroscopicity, and good compatibility support use in solid blends and granules.
