Who can participate in the QS scheme via a multi-site certification?
A multi-site certification is possible for companies with a main location and several storage, transport or trading locations that belong to the same company. In addition, it is possible to integrate a group of companies that work together in a quality alliance and form a network of affiliated companies into the QS scheme as part of a multi-site certification. The network of affiliated companies does not have to be a legal entity. To enable multi-site certification for a network of affiliated companies, the main location must inform the QS office which companies and which locations belong to the bundle and submit the appropriate agreements for multi-site certification.
