SEA considers its suppliers to be key partners in its sustainability journey, and the foundations of this partnership are:

  • Sustainable Procurement Policy, SEA's commitment to creating a sustainable supply chain;
  • Supplier Code of Conduct, sharing principles for developing a sustainability journey with all suppliers;
  • Open-es, a shared platform on sustainability experiences open to all suppliers.

Watch the webinar video at the following link.

If not already on the platform, register on Open-es. Remember to grant visibility of your data to SEA, even if you are already registered.


SEA is revamping the Suppliers Portal.

Within the current Tender Portal, new processes aimed at registration in the Suppliers' Register and Qualification Systems will soon be activated, complementing the current functionalities related to participation in negotiation events. In order to use these new features, it is necessary to generate credentials to the new Suppliers Portal, following the instructions you will find in the attached file.

With these credentials you can as of today directly access the suppliers management page, which will continue to be active, even in the new version of the platform, for the negotiation events in which you are involved. You will in any case be able to continue accessing the Suppliers Portal also with the current modes and credentials in your possession.


If you need to continue accessing the "Reserved Area" of the pre-existing Supplier Portal, you can connect to the link.

In case of problems, please contact Helpdesk.
