UN+TDED

The United Nations Trade Data Element Directory (UNTDED, ISO 7372) is developed and published by UN/CEFACT. A UN Layout Key (UNLK) trade document has boxes that specific data can be put in. The requirements for each box are recorded in a dictionary called the Trade Data Elements Directory (UNTDED, ISO 7372). This directory consists of a four-digit number to identify each data element, a data element name and a description that provides a definition of the data element. It provides an internationally accepted standard repository for the semantics of trade data elements used in international trade. UNTDED has also been integrated into the latest standards for electronic trade documents, such as the UN/CEFACT Core Component Library (CCL) or UN/EDIFACT. Therefore UNLK, CCL and UN/EDIFACT are intrinsically linked because of UNTDED.
