The basic legislation from which the present import-export control system in Belgium has developed was a law of June 30, 1931, modified by the law of July 30, 1934, which authorized in broad general terms the regulation of Belgium's foreign commerce to promote the general economic well-being of the country. The convention with the Grand Duchy of Luxembourg on the 23d of May 1935, amending the economic union convention of 1922, established also a combined Belgo-Luxembourg Administrative Commission (the Commission Administrative Mixte Belgo-Luxembourgeoise) and in this way provided a central agency for coordinating the import and export licensing procedures of Belgium and Luxembourg. Pursuant to the 1935 convention, when the appropriate agency of either Government desires to modify or expand regulations pertaining to import and export controls, the recommendation is discussed with the appropriate agencies of the other Government; their agreement having been reached the new policies are communicated to the Mixed Commission which then transmits identical instructions to the Belgian Central Office of Licenses and Quotas and the Luxembourg Office of Licenses. This procedure insures close coordination of the import and export licensing operations of the two Governments in order that the general economic welfare of both may best be served. The control over exports effected by the requirement of export licenses is reinforced by special controls applied at the time of the actual export of the licensed merchandise. Submission to these special controls is required as a previous condition to the obtaining of certain licenses, these special additional controls being applied by reason of the special nature of the merchandise to be exported or to assure the direct delivery of the merchandise to its foreign destination. Applicants for export licenses must make a declaration that they are familiar with the conditions upon which licenses are issued and the regulations relative to exchange controls, and that they accept these conditions and regulations without reserve. The applicant also acknowledges that the licenses are not transferable and that any irregularity in his application or utilization of the license subjects him to possible refusals of any new export license applications and may expose him to prosecution for a criminal offense. Exporters of products whose final destination is controlled must sign an undertaking that their exports are not to be reexported. In such cases, the exporter renounces his right to obtain any subsequent export licenses in all cases for which nonreexport declarations are required, if the present undertaking is evaded. At the present time, licenses are not required for goods passing in transit through Belgium, with the exception of arms and implements of war and atomic energy items, as well as petroleum and its subproducts.
