Control regimes in international trade can be subdivided into two basic types: Prohibitions and Restrictions. This distinction is essential to the correct mapping of their legal bases in SAP Global Trade Services (SAP GTS).

A commercial transaction could, for example, be prohibited due to sanctions against a person involved in this transaction. Import and export restrictions often take the form of a requirement to obtain official permission prior to the execution of a commercial transaction. Other restrictions limit the quantity or the value of a commodity that may be imported or exported.
In this context, the term "permission" is quite broadly defined. A permission could, for example, be an authorization, a license or an official certificate of any kind.
