Recital 20

(20) The increased digitalisation of customs and Union non-customs formalities applicable to international trade has opened up new opportunities for Member States to improve digital cooperation between customs authorities and partner competent authorities. In pursuit of those opportunities and priorities, several Member States have started to develop frameworks for national single window environments for customs. Those initiatives differ substantially depending on the level of existing customs information technology architecture, priorities and cost structures. It is therefore necessary to require Member States to establish and operate national single window environments for customs for Union non-customs formalities covered by EU CSW-CERTEX, with a minimum set of functionalities enabling all the data present in Union non-customs systems used by partner competent authorities to be exploited. Those national single window environments should constitute the national components of the EU Single Window Environment for Customs, enabling the exchange of information and cooperation by electronic means between customs authorities, partner competent authorities and economic operators to ensure compliance with and efficient enforcement of customs legislation and Union non-customs formalities covered by EU CSW-CERTEX. In line with that objective, the national single window environments for customs should enable the automated verification by customs authorities of formalities in respect of which data is transmitted from the Union non-customs system through EU CSW-CERTEX. The national single window environments for customs should also allow partner competent authorities to monitor and control the quantities of authorised goods (‘quantity management’) that have been released by customs authorities through the Union. This should be ensured by providing the necessary clearance information to the Union non-customs systems through EU CSW-CERTEX. In practical terms, quantity management at Union level is necessary to enable better enforcement of non-customs formalities by automatically and consistently monitoring the use of authorised quantities for the release of goods, avoiding their overuse or mishandling. The connection of the national single window environments for customs with EU CSW-CERTEX would facilitate efficient quantity management at Union level.
