ISO certification
To deliver the highest quality to our customers, we strive to ensure that our internal processes meet global standards. Therefore, ISO certifications are an essential part of our quality assurance system. The GLS Group has been ISO certified since 2013, with ISO 9001 recognizing our effective quality management and ISO 14001 focusing on our environmental management.
Our ISO certifications involve thorough quality assurance with clearly defined processes, quality guidelines, and regular audits. With group certifications, all GLS companies commit to the same high standards. A negative evaluation of a single company would consequently affect the entire group, which requires streamlined management of our internal processes to maintain ISO 9001:2015 and ISO 14001:2015 certification.
Auditing is conducted in collaboration with DEKRA, a globally recognized player in management system certifications.
