Guidelines & Technical Approaches to the Single Window Environment
Even as there are several Single Window initiatives taking shape all over the world, there are no clear standards or guidelines concerning this area. Customs is increasingly being expected to participate in and take responsibility for Single Window implementations.
The document “Single Window: Implications for Customs Administrations” describes the possible impact that developments around a Single Window Environment has on the future of Customs' Business.
WCO has developed Single Window Data Harmonization Guidelines to provide Single Window environment developers with tools that can be used in order to achieve data harmonization and to develop internationally standardized data sets including the data element names, definitions, the United Nations Trade Data Element Directory (UNTDED) tag and the formats.
The United Nations Centre for Trade Facilitation and Electronic Business (UNCEFACT) has developed Recommendation 33 on the subject, which is an important piece of work in this area.
