In the context of the active development of international trade and the growth of the volume of goods transported across borders, there is an increasing need to improve customs administration. One of the tools for improving the efficiency of customs authorities is the technology of preliminary information. It allows you to receive, process and analyze data on the transported goods and vehicles in a timely manner even before they arrive at the customs territory. In this regard, the optimization of the pre-notification system will significantly reduce the time required for customs operations and increase the effectiveness of interaction between the state and participants in foreign economic activity.
