As you know, the accuracy of customs declarations is a concern for the Customs Administration. Constantly on the lookout to develop trade, ensure the speed and reliability of customs clearance operations and the collection of statistics.

In 1974, a computer system for the processing of International Air Freight (SOFIA) was created. Very quickly operational at the Roissy and Orly sites, it was extended in 1978 to other modes of transport and renamed SOFI.

In 1971, the Computer Center (CID) ensured the deployment of this new system in the customs offices. In 2007, SOFI was replaced by the DELTA system.

The DELTA system is an online service dedicated to all operators who import goods from territories outside the European Union.

Initially, we are talking about DELTA G, DELTA X, DELTA X Export, ECSBS and then DELTA IE, which will eventually replace all of the above applications.

This is the end of the SAD (Single Administrative Document) and the birth of a new vocabulary, a series of new data and electronic messages. This system will be fully automated between the Member States for operations and for operators who currently have a DCC authorization.

Delta IE (import-export clearance) will become mandatory from July 1, 2023 for the H1 declaration. It will no longer be possible to file a direct import customs declaration in DELTA G/X.

DELTA G import and DELAT X import can still be used until June 30, 2024 for rectification or invalidation requests.

For exports, DELTA IE Export will be phased in gradually, starting on October 2, 2023.
