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 workplace. The basic principle is the prevention of problems rather than subsequent correction.


Certifications in the pharmaceuticals and food segments

All food additives and active pharmaceutical ingredients within the “Health Care & Nutrition“ sector are certified in accordance with DIN EN ISO 9001 ff., in addition to being Kosher and Halal approved. Beyond that, we use the following specific systems for the individual product segments:


Active Pharmaceutical Ingredients: GMP in accordance with ICH Q7
Food additives: HACCP

Certifications in the feed segment

All KaSa®-products are certified in accordance with DIN EN ISO 9001 ff. and GMP+ and are QS-recognised. These systems are subject to continuous internal and external controls.

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.
