The quality

Beyond standard

Quality and continuous further development form the basis of our corporate philosophy. We have had a certified quality management system in place since 1993.

Nevertheless, we do not rest on our laurels. We always set our internal bars higher than the applicable rules and standards. We keep our standards at the highest possible level, for example by offering regular internal and external training courses and workshops for our employees.

With these exacting quality standards in mind, we also select our suppliers and raw material sources.

We cooperate exclusively with partners who adhere to the same strict quality criteria and philosophy as we.

We rigorously check and analyse our raw materials and end products to verify that the relevant parameters, such as chemical purity, grain size distribution, BET surface area, etc., are correct.

Consistent quality checks along the entire process chain, from incoming goods control to the final product and its shipment to the customer, ensure the utmost in product quality all the way through.


We apply the same high standards in the selection of our partners. In this way, we can be sure that our very strict quality criteria and exacting quality demands are complied with along the entire value chain of our products.

Since March 1993, CS Additive (or its predecessor) has been DIN EN ISO 9001-certified. For those interested, the DIN EN ISO 9001:2015 quality management certificate is available for download as a pdf file:
