[en] Paraguay shares its borders with Argentina, Brazil and Bolivia. Import and/or export loads must be subjected to several types of controls before arriving at their destination; this includes controlling for radioactive substances and anticipating illicit trafficking of radioactive material. In order to improve control at border points, the National Direction of Customs of Paraguay decided to install detectors in the primary zones of ports, airports and railway terminals, and of areas of automotive transport, as well as at other locations where loading and unloading of goods takes place. Adequate control of exported and imported merchandise diminished for several reasons: false declaration of the weight of products, irresponsible personnel, robberies, political influences, camouflaged or hidden drugs, lack of detectors and qualification of civil employees. These are some of the reasons why merchandise from Paraguay is given low credibility and is not accepted in foreign ports. For this reason, the National Direction of Customs of Paraguay decided to change the image of the country and adapted to the international exigencies of worldwide commerce. The normative framework to ensure and to facilitate global commerce, with the support of the World Customs Organization (WCO), was signed in Brussels on 25 June 2005. Thus, Paraguay fulfils Law 2422/04, implementing systems of control that avoid trafficking in drugs, robbery of radioactive material, dangerous arms and substances, which appear to be camouflaged between imported and exported merchandise.
