Revision 1.7 of the Export Web Services guide for the exchange of information between Operators and Customs in the new AES (Automated Export System) is published. This guide collects messages from the external domain (communication between the Economic Operator and the Tax Agency) of the national component of the Automated Export System (AES), as well as the adaptations that may be necessary for the improvement of National Export Systems in line with the Union Customs Code (CAU). This new revision changes www3 references to www2. The guide is now complete with detailed definitions of all messages.
The planned implementation schedule for the system is as follows:

The Web Services of the new AES system, detailed in this technical guide, have been available in the test environment since November 10 and in the real environment since October 4, 2022.
From 04/22/2023, the Web Services of the AES system will be mandatory, since on that date the admission of EDIFACT messages from the ECS system will be closed.
