Revision 1.3 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 adds detailed descriptions of new services among other changes. 　

Remember that the guide includes a section on the planned implementation schedule for the system.
