Potassium Permanganate (KMnO₄) Supplier, Exporter & Global Wholesaler
PAU Chemicals is an India-based global supplier and exporter of Potassium Permanganate at 99% minimum, in water treatment, pharmacopoeial and technical grades.
Potassium Permanganate is a powerful oxidiser recognisable by its deep purple crystals. In water treatment it removes iron, manganese, taste, odour and colour in a single step — which is why it remains standard practice at groundwater plants worldwide.
PAU Chemicals supplies free-flowing crystal and powder grades with assay and insolubles documented per batch, packed in sealed steel or HDPE drums for oxidiser transport.
Potassium permanganate is an internationally monitored chemical because of its misuse potential. Legitimate buyers should expect end-use documentation requirements and, in many countries, pre-export notification — build that into your procurement timeline.

What is Potassium Permanganate, and what is it called locally?
It is a strong oxidising salt, KMnO₄, recognisable by its deep purple crystals. In many markets it is simply called permanganate or purple crystals.
What is it used for?
Removing iron, manganese, taste and odour in drinking water treatment, oxidising wastewater contaminants, aquaculture treatment, ethylene absorption for fruit ripening control, and metal surface treatment.
Why is it used for iron and manganese removal?
It oxidises dissolved iron and manganese into insoluble oxides that can be filtered out, and it handles taste, odour and colour in the same step — which is why it is standard at groundwater plants.
Is it hazardous to store and handle?
Yes. It is a strong oxidiser (UN 1490, Class 5.1). Contact with organic material, glycerol, acids or reducing agents can cause fire. Store it separately, in sealed containers, well away from combustibles.
Are there import or export controls on this product?
Yes. It is internationally monitored because of misuse potential, and many countries require pre-export notification and end-use documentation. Confirm your national import requirements early, as this affects timelines.
Do you supply pharmacopoeial grade?
Yes, to IP and BP where required, documented separately from technical and water treatment grades.
How should it be stored, and what is the shelf life?
Cool, dry and sealed, in a dedicated area away from organics, acids and combustibles. It is stable indefinitely under those conditions but stains permanently on contact with skin and surfaces.
How is DG shipping handled, and does it affect delivery time?
It ships as UN 1490, Class 5.1, PG II. We arrange UN-approved packing, IMO labelling and DG vessel booking. Oxidiser slots are limited and documentation checks are stricter, so allow additional lead time.
