Quality management

Quality awareness has always been a key element of our corporate culture. Based on DIN EN ISO 9001 ff., K+S KALI GmbH has established a Quality Management System which, among other objectives, guarantees continuous monitoring and improvement of our product and service quality.

Within K+S KALI GmbH, Quality Management is a leadership function throughout all levels of responsibility and includes each employee at his or her place of work. The basic principle is the prevention of problems rather than retrospective cures.


All the products within the “Industrial Salts“ sector, as well as different departmental functions and processes that are in place to service our customers, have been certified in accordance with DIN EN ISO 9001 ff..

Controlled raw materials

Nearly all of the raw materials used by K+S KALI GmbH are mined from company-owned underground deposits. This assures a reliable supply of top-grade raw materials, making us the dependable partner for your needs.

High demands on contractors & suppliers

For manufacturing all K+S KALI-products, only those additives, excipients, auxiliary and packing materials are used, which comply with our exacting demands on the final product’s quality.


All materials used and their suppliers therefore need to adhere to a strict catalogue of criteria.

Quality control for impeccable end products

Our products form part or all of your base materials – and we are glad to face this expectation. We therefore consider quality controls as a matter of course. K+S KALI GmbH Quality Control rests on three pillars:

  • Each product has individual specifications. Based on the relevant physical and chemical parameters, these are continuously monitored at our in-house laboratories, at all production sites. On request, we are glad to certify conformance with these specifications, through a certificate of analysis accompanying the individual shipment. As a complementary measure, we strive to identify any deviations of our raw materials or our manufacturing processes, by inspecting a host of additional parameters.
  • The accredited central laboratory of the K+S Research Institute supports the work done at the on-site laboratories, but also develops its own specific methods of analysis. From time to time we assign analyses to other accredited external laboratories, which have proven themselves as reliable partners over many years of cooperation with K+S KALI GmbH.
  • The third pillar of our quality assurance system is the application-technological laboratory. This is where specialists with a wide breadth of experience benchmark our entire range of products, examining their applicability for our customers’ processes, and further application options.
