Brief Summary

The EU CDM is the data model for Customs trans-European systems such as NCTS , AES, ICS and for Member States national systems. It provides a technical instrument and source of information for the IT systems used for data processing by customs in the EU. 


a. Objective(s)

The EU Customs data model (CDM) is the data model for Customs trans-European systems such as NCTS (new computerized transit system), AES (automated export system), ICS (Import Control System) and for Member States national systems.

The system aims to provide a technical instrument and source of information for the different IT systems that are used for data processing by customs in the EU.The backbone of the EUCDM is the data provided by traders to customs authorities by means of the different declarations and notifications. Also EUCDM will be integrating data elements for the exchange of data between customs authorities, as well as those provided for in UCC-DA and UCC-IA Annex A.

The EUCDM has a global importance and achieves this by mapping to WCO to be fully compatible and to link data elements in the WCO Data Model so to reliably and unambiguously relate Customs needs and Economic Operators data.

b. Business need for the project (background)

To create a tool for integrating the needs and requirements of other administrations active at the border.

To create coordinated border management.

c. Business process covered*

Overview of all customs business domains and global business data within EU customs

Interaction between customs domains and depiction the input and output high level data for each customs business domain

Interaction between main business processes within one business domain

Depiction of detailed business process flow and conceptual data elements as defined in the UCC legislation

The functionality of the envisaged system, information exchanges , data rules and conditions, system requirements and test scenarios.

d. Overall architecture and functionalities*

e. Relevant document/figure

14A. Elaborations/detailed description on benefits gained

Global trade facilitation

Further expansion of regional integration

EU integrated approach found its concrete form in EU CDM which is entirely compatible with WCO DM.

15. Technical/financial/capacity building/other assistance
16. Future plan for expansion of the project

Reusing and customizing the WCO DM, in line with the needs of associated administrations active at the border.

Implementing national adaptations in combination with customizations, whilst ensuring compatibility with the WCO DM and the EU CDM, the objective being to allow administrations to adapt the EU CDM to include their own national specificities which are not provided for in EU law.

Exploring additional opportunities for cooperation with economic operators in relation to the use of the EU CDM for streamlining and automation projects, which should further facilitate and harmonize the exchange of information between Customs and economic operators.

17. Other information or relevant references on the project

From a technical perspective, the EU CDM and WCO data tool used to manage it enables the auto-generation of national document structure publications for both single documents and their supersets, and the auto-generation of nationally used XML schemas – exchange interfaces of all Member States which follow the same XML design will be technically interoperable.

Both the publication of a national document structure and XML schemas constitute intermediate technical documents, which take the legal requirements and translate them into a readable format for IT developers, enabling software developers to perform their tasks. They include message structures, rules and conditions, as well as specifications, applying to the national document structure and XML schemas.
