A sorting label or customs declaration is a document that contains information about the cargo and is used to control the customs clearance process. It is necessary so that the authorized customs authority can check the completeness of the cargo, determine the amount of customs duties and taxes that will be paid when exporting cargo from the territory of the Russian Federation or when importing it into the territory of the Russian Federation.
