The prerequisite for the closing of an export declaration is that the number of the declaration is recorded in the relevant section of the transit declaration, in other words, the opening is made.
Closing of the transit declaration and closing of the export declaration are different. Even if the transit declaration is not closed, the export declaration can become closed status.
When the goods are exported by road, the export declaration closes automatically. In sea and air transportation, it is closed by the relevant officials upon the notification of exit.
