4C System Users
List of Certification Bodies
Third-party auditors are independent, accredited, known as Certification Bodies within the 4C System
In the 4C System, the standard itself is developed and overseen by the 4C team, but compliance is verified independently. To ensure transparency, credibility, and trust, 4C follows a third-party certification model. All audits are conducted by external, accredited auditors who apply the standard objectively across global supply chains.
For a list of our cooperating 4C Certification Bodies below, follow this link to the 4C Portal.
4C Core Certification
A producer group wishing to obtain 4C certified can check the list of responsible auditors operating in the country of production (column: “countries to conduct 4C audits”).
4C Chain of Custody Certification
To obtain Chain of Custody certified there is no limitation by country.

All 4C cooperating Certification Bodies (CBs) must be approved by 4C. In case, you would like to become a 4C cooperating CB, please get in touch with us via info@4c-services.org
