If you trade or transport goods across borders, you must observe special regulations. One of these is to declare the goods properly to customs. This requires an electronic export declaration from a certain value of goods or a certain trade volume. The customs declaration serves, among other things, to monitor exports (export control). Export declarations are processed via ATLAS, the "Automated Tariff and Local Customs Clearance System". In addition to special software for the IT procedure ATLAS-Export, you can also use the web application "Internet Export Declaration Plus" (IAA-Plus). With IAA-Plus, you submit your declaration electronically with a signature. This declaration is reminiscent of an e-mail, which can be generated automatically via an interface. The IAA Plus is aimed at companies that rarely or only export a few goods export goods very frequently under the simplified procedure or submit a simplified export declaration, submit a simplified export declaration as a subcontractor in direct representation, cannot or do not want to purchase their own ATLAS software, do not wish to use an ATLAS service provider or a customs office.
