On 2 October 2017, the Commission launched the Customs Decision System (CDS), a pan-European electronic system through which companies now have to apply online for authorisations and customs decisions under the UCC that involve more than one Member State. The system can be accessed through the EU Trade Portal. CDS brings together 22 types of applications and will also hold post-application/decision information (e.g. on amendment, revocation, suspension or annulment of decisions). The Commission has made available an eLearning module on CDS.

Meanwhile, on 14 November 2017, the Commission adopted Implementing Regulation 2017/2089 on technical arrangements for developing, maintaining and employing electronic systems for the exchange of information and for the storage of information under the UCC which applies to CDS (as well as to the Uniform User Management and Digital Signature system).
