Period of 15 years of the post-Soviet collaboration is linked to a number of differences and the customs legislation of the Member States C. S. I. is poor. Thus emerged clearly need to develop a collaborative scientific concept of Moldova with other post-Soviet sphere of customs activity. First, the legal regulation of post-Soviet cooperation in the sphere of customs activity is criticized both by scholars, as well as collaborators in practice. Although customs integration of post-Soviet countries is an objective necessity and serves as an integral part of economic, legal problems related to this have not been adequately studied, therefore, were often misinterpreted. Secondly, the development and establishment of free trade zone with the post-Soviet states-members of CIS are of great importance for Moldova. Legal regulation of customs cooperation serves as a special economic base of Independent States. Unfortunately, at present, this question has not been elucidated in terms of the theory of law. Its scientific research would lead to solving of many problems in the process of unifying the customs legislation of the post-Soviet countries. Therefore, it is noteworthy that the problem requires a thorough scientific research, both in terms of theory and practice. Thirdly, the topic can serve as the concept of customs cooperation in general, including the fact that Moldova was accepted as a member of the World Trade Organization and should strengthen development custom cooperation with states that are not Member of the Community. Possibility for legal issues within CIS show preparedness of post-Soviet states, including Moldova, to participate in the work of international organizations in addressing issues of commercial and customs cooperation. Fourthly, the issue is welcome to legal doctrine, because during the research process will be characterized several new concepts, previously unknown to the general theory of law, such as Free Trade Zone, integration, single customs territory, etc.; which we should give a scientific interpretation. This theme will serve as the topic for scientific discipline of custom law, as well as to the entire public law. The aim of this study is a very compelling elucidation of a problem for the theory and practice of customs law - the problem of unification of customs legislation of post-Soviet countries, as well as developing proposals, objectives that would lead to resolution of these problems during the process of European integration.
