The article discusses the transition to the final phase of the AES-P1 system in the EU, scheduled for December 15, 2025. A new version of the system documentation, SXML - 2.10.005, will be implemented, and there may be challenges with goods identification due to the lack of a legal requirement for the accompanying export document (EAD).

  • Transition to AES-P1 will occur on December 15, 2025.
  • New system documentation version SXML - 2.10.005 will be in effect.
  • Some countries, including Poland, will continue to generate and use the EAD document.
  • Customs declarations registered in AES/ECS2 PLUS before December 15, 2025, without an MRN will receive a rejection message.
