Cooperation: a cornerstone of the EU’s Customs Union

To enable a Customs union to operate properly, active cooperation between Customs authorities within the union must be established. This cooperation is not necessarily limited to legal issues touching on “core” Customs domains, e.g. regulating import and export formalities or establishing a common tariff. An effective Customs union must also provide for Customs authorities to cooperate on law enforcement issues, in order to ensure security and safety within the union, and the effective and efficient fight against crime.
