It is also sold as KCl, Muriate of potash, Sylvite. All refer to CAS 7447-40-7. Confirm the CAS number with any supplier before ordering.

Price depends on grade, volume, packing, Incoterm and destination port, and moves with raw material markets. Send us your requirement and we will quote in EUR or USD with a landed-cost breakdown, usually within one business day.

Potassium Chloride (CAS 7447-40-7) is a white crystalline salt used as the principal source of potassium in fertilisers, and as a raw material in pharmaceutical, food and industrial chemical applications.

Standard grade offers 99.0% minimum KCl assay, typical of fertiliser and general industrial use. Premium grade offers 99.5% minimum with lower sodium and insolubles, suited to technical and pharma-adjacent applications.

Standard fertiliser (agricultural) grade is our usual offer, with higher-purity technical and pharmaceutical-intermediate grades available on request. Tell us your intended use (fertiliser blending, industrial feedstock, or pharma/food-adjacent use) so we can confirm the correct grade and any additional certification you need.

Potassium Chloride is not itself classified as hazardous, but fertiliser-grade material can face country-specific fertiliser regulations, and pharmaceutical or food use requires separate grade certification. We confirm the current status for your application before quoting.

Store in closed, moisture-proof containers or bags in a dry, ventilated place. It is non-combustible and chemically stable; keep away from strong oxidisers as a general precaution.

It is generally not classified as dangerous for transport. We pack it in standard or UN-rated containers as required, apply appropriate labelling and ship through our regular forwarders under standard sea and European road terms.

Yes. Laboratory and pilot samples are supplied with a COA and SDS so your team can qualify the grade. Mention sample needs in your enquiry.

REACH status is confirmed before we quote. We advise on importer-of-record arrangements and whether the substance is registered for your use. Send your use descriptor and we will confirm.
