A reliable and transparent whistleblowing system is crucial for detecting and appropriately responding to legal violations and breaches of guidelines.

To report potential compliance issues, we provide our employees, as well as customers, suppliers, and other third parties, with various reporting channels.


Via our web-based whistleblowing system, potential legal or policy violations within TKD can be reported—optionally, anonymously. This system is accessible to all employees, as well as customers, suppliers, and other third parties.

The receipt and handling of your report are managed by sicdata – Unternehmensberatung, our appointed external whistleblowing protection officer. As professionals bound by confidentiality, sicdata is obligated to handle the identity of whistleblowers and received information with absolute discretion. In addition to traditional channels like email or phone, sicdata provides a whistleblowing system designed for maximum confidentiality (no forwarding to unauthorized persons or other disclosures).

Each report received is carefully reviewed and evaluated by our external whistleblowing protection officer, potentially involving the company’s management.

To access the web-based reporting form, please use the following link:
