EU Regulation 2019/632/EU is to extend the transitional period for non-electronic data transmissions required by the UCC. Under the UCC, all exchanges of information between customs authorities and between economic operators and customs authorities, and the storage of such information, are to be made using electronic data-processing techniques. The transitional period before this became mandatory was intended to end on 31st December 2020. However, the new Regulation says that it has become evident that some systems can only be partially deployed by that date; and this implies that some pre-existing systems will need to continue in use beyond that date. In the absence of legislative amendments extending that deadline, companies and customs authorities will be unable to perform their duties and legal obligations as regards customs operations. New deadlines are provided for in the new Regulation – 31st December 2020, but 31st December 2022 or 31st December 2025 for certain specific reporting and communication requirements. The EU Commission will make annual reports on progress.
