Procedure of Complaints and Appeals
4C Units, 4C Certification Bodies, and other parties have the right to lodge complaints and appeals when feeling discontent with services or situations in the context of certification or disagreeing with a decision made by any of the parties involved.
Formal complaints and appeals on certification matters can be filed by a letter or e-mail. They should include a clear description of the nature of the claim, justification of the claims, and supporting evidence. More detailed information on the complaints and appeals procedure can be found in the 4C System Regulations v.4.0, Chapter 3.7.
Please send your complaint in written form to the 4C Services GmbH office at:
