Made in Germany – The quality seal 

The TÜV certification inspection procedure is a 3-months process, which gets accomplished by satisfying a strict list criteria. Completion of the technical inspection gives accreditation to the suppliers of the resources and raw materials prior to shipping, verifying the overall quality and added value of products. The effort was worth it. The certificate was presented, allowing the use of proof of origin "Made in Germany".


TÜV (Association for Technical Inspection) –
Quality, effectiveness and compatibility

Product development requires both proven effectiveness and optimized compatibility in the area of application. As one of the first companies in Germany to do so, CTP GmbH's products have been tested and are certified by accredited testing facilities. Since 1998 the products are tested for effectiveness under testing procedures that have been especially developed for their products. Since 2011 CTP's products are tested according to DIN regulations to fulfill the strict requirements of the automobile industry.
