The EU Customs Data Model (EUCDM) is the model for Customs trans-European systems such as NCTS, AES, ICS, EOS and for Member States national customs clearance systems. Its overall objective is to provide a technical instrument that models the data requirements laid down in EU Customs legislation and present a single and genuine source of information for the technical developments of the different IT systems that are used for data processing by customs in the EU. In consequence, the data elements which are used only in the context of paper-based declarations, are included exclusively in the reproduction of the legal text, but not in the mapping and structure reports.

As of 19 July 2019, a new version of the European Union Customs Data Model (EUCDM) web-publication is live and accessible for the whole world! EUCDM 4.0 reflects all the recent changes in the customs legislation which affects the data requirements. The new version now also contains the provisions for the low value consignment data-set.
By using the web-publication of the EUCDM all interested parties can see the legal provisions of the UCC DA and UCC IA in a reader-friendly, structured way, thus facilitating the use of information.
