The Eurasian Economic Union Customs Code Agreement envisages a gradual liberalization of customs regulations and the creation of more comfortable conditions for doing business. The customs system will in effect be transitioning to a radically new level of functionality, with customs operations improved by the implementation of data management systems which do not require the involvement of customs officials, the translation of customs procedures into electronic versions, the priority replacement of paper with modern technology, increased legal significance for preliminary information, expanded opportunities for releasing goods prior to the submission of a declaration, increased status for authorized economic operators, and an expansion of simplifications made available to them here and in a number of other areas.
