Search Revenue extends dual running of Customs Import Systems until 31 March 2021 Revenue’s new customs declaration system, the Automated Import System (AIS), was launched on 23 November 2020. The new modernised system, which reflects all the legal requirements of the EU Union Customs Code (UCC) and is designed to replace the Automated Entry Processing (AEP) declaration system for imports, is being actively used by some 130 customs agents and businesses. Customs import declaration filing volumes in AIS now exceed those being filed via AEP. To date, 47 of the top 50 agents and businesses who file import declarations are using AIS. This level of activity on the new system reflects the excellent engagement by trade and business and by the software providers in adopting the new system.
