Temporary storage of goods is the storage of foreign goods in temporary storage facilities until they are released by the customs authority or until the customs authority receives permission for the departure of goods from the customs territory of the Eurasian Economic Union.  

This does not apply to goods transported by pipeline or via power transmission lines. Temporary storage warehouses and other temporary storage facilities are designated places for the temporary storage of goods.

Temporary storage facilities are considered a customs control area. In order to place goods in temporary storage, the carrier or another person with authority over the goods must submit transport (shipping), commercial, and (or) customs documents containing information about the goods, their sender, recipient, country of departure, and country of destination to the customs authority.

Alternatively, it’s possible to provide a document containing the registration number of the preliminary information submitted as an electronic document. Documents can be submitted to the customs authority in electronic form.

The customs authority will register the documents submitted for the temporary storage of goods no later than one hour after submission. The period of temporary storage is four months and calculated from the day following the registration of the documents.
