Nowadays, the efficiency of customs administrations depends on the ability to efficiently manage a huge bulk of information and data that increasingly are transmitted electronically and whose circulation most times precedes that of the goods. To do that, Customs need to develop the capability to interconnect or share parts of such informative flows with other government agencies on one side, and economic operators on the other side. A new research paper from WCO examines problems and critical aspects related to the implementation of Single Window systems, one of the most important tools for trade facilitation.
