One standard for all

As a system-based general cargo network, we ensure that all system partners meet the same high quality and environmental standards. Our partners are certified according to these standards:


quality management

DIN EN ISO 14001

environmental management


food safety

DIN EN 16258

CO2-footprint according to DIN EN 16258

Our quality management

To achieve and maintain a consistent level of quality for all system partners, we audit new partners six months after they join the network. We accompany them personally step by step through the demanding certification process, prepare internal and external audits together and are also on site during the certification itself.

Digital certification

The basis of every certification is the checklist with questionnaire, which we have prepared in such a way that it can be processed particularly efficiently. Using our dedicated software, OSL partners will soon be able to edit the checklist, confirm audit dates and upload all the required documents.
