ZD places the highest demands on information security and sustainability. Accordingly, we are proud of the certificates we have received, which confirm our success in these areas. These are now published on our homepage, in addition we want to briefly discuss the two awards in this post and explain how we were able to achieve them.


The TISAX label is roughly comparable to the internationally known standard for information security, ISO 27001 – to which our Chinese subsidiary is also certified. The main difference between the certificates is that TISAX is specifically tailored to the requirements of the automotive industry and is based on the requirements of the German Association of the Automotive Industry (VDA).

As part of our preparation for the audit, we optimised our internal processes and tightened our safety measures even further – together with the energetic support of our employees, we passed the audit without any problems and have been the proud holders of the TISAX label ever since.


SAQ stands for Self-Assessment Questionnaire and is a questionnaire published by NQC SupplierAssurance. It covers a wide range of areas relating to sustainability, working conditions, ethics, the environment, supplier management and raw materials. The SAQ is widely used in the automotive industry and demonstrates a company’s commitment to the broad field of sustainability.

ZD has already completed the current version 4.0 and, thanks to multiple measures, has been able to achieve a strong result in the area. We are also proud of this and will work to implement even more measures in the future.

Once again, we would like to take this opportunity to thank all our employees and partners, through whom we were able to achieve these certificates in the first place. Together we will continue to develop in the field and thus work towards a better future.
