We invest in quality.

We have made a significant investment to implement certified management systems in various areas.


With this strategic investment, we wish:

  • to improve our services’ quality  
  • to optimize the processes in the various value chain’s phases
  • to develop and encourage the employees’ participation
  • to improve the customers’ satisfaction
  • to reinforce CTT’s image


The certification processes’ success has raised a strong internal motivation. These are projects that demand a great coordination effort because they cover around 1.000 premises and more than 12 thousand employees.

When implementing the management systems, we adopted different timings and approaches to the different CTT Group departments. Below there is a list of the companies and units that are already certified, and the rules applied to certification.
