Maritime National Single Window

1. Each Member State shall establish a maritime National Single Window through which, in accordance with this Regulation and without prejudice to Articles 7 and 11, all information necessary for the fulfilment of reporting obligations shall be provided once, by means of and in compliance with the EMSWe data set, using the harmonised reporting interface module and the graphical user interface as set out in Article 6 and, where applicable, other reporting means as set out in Article 7, for the purpose of making this information available to the relevant authorities of the Member States to the extent necessary to allow those authorities to perform their respective functions.

Member States shall be responsible for the operation of their maritime National Single Window.

Member States may jointly establish a maritime single window with one or more other Member States. Those Member States shall designate that maritime single window as their maritime National Single Window, and shall remain responsible for its operation in accordance with this Regulation.

2. Member States which do not have maritime ports shall be exempted from the obligation to develop, establish, operate and make available a maritime National Single Window which is set out in paragraph 1.

3. The Member States shall ensure:

the compatibility of the maritime National Single Window with the harmonised reporting interface module and adherence of the graphical user interface of their maritime National Single Window to the common functionalities in accordance with Article 6(2);

the timely integration of the harmonised reporting interfaces in accordance with the implementation dates set in the implementing act referred to in Article 6 and any subsequent updates in accordance with the dates agreed in the Multi-annual Implementation Plan (MIP);

a connection with the relevant systems of competent authorities, to enable the transfer of data to be reported to those authorities, through the maritime National Single Window, and to those systems, in accordance with Union legal acts and national legislation and requirements, and in compliance with the technical specifications of those systems;

the provision of a helpdesk during the first 12 months from 15 August 2025 and an online support website for their maritime National Single Window with clear instructions in the official language(s) of that Member State and, where relevant, in a language that is internationally used;

the provision of adequate and necessary training for staff who are directly involved in the operation of the maritime National Single Window.

4. Member States shall ensure that the required information reaches the authorities in charge of the application of the legislation in question, and is limited to the needs of each of those authorities. In doing so, Member States shall ensure compliance with the legal requirements related to the transmission of information, provided for in the Union legal acts listed in the Annex and, where applicable, use the electronic data-processing techniques referred to in Article 6(1) of Regulation (EU) No 952/2013. Member States shall also ensure interoperability with the information systems used by those authorities.

5. The maritime National Single Window shall provide the technical possibility for declarants to make available, separately, to providers of port services at the port of destination a subset of data elements pre-defined at national level.

6. Where a Member State does not require all of the elements of the EMSWe data set for the fulfilment of reporting obligations, the maritime National Single Window shall accept submissions that are limited to the data elements that are required by that Member State. The maritime National Single Window shall also accept submissions by declarants that include additional elements of the EMSWe data set; however, it does not need to process and store those additional elements.

7. Member States shall store the information submitted to their respective maritime National Single Windows only for the period of time necessary to ensure the fulfilment of the requirements set out in this Regulation and to ensure compliance with the Union, international and national legal acts listed in the Annex. Member States shall immediately delete such information thereafter.

8. Member States shall make publicly available estimated and actual arrival and departure times of ships in an electronic format harmonised at Union level, on the basis of the data submitted by declarants to the maritime National Single Window. This obligation shall not apply to ships carrying sensitive cargo, where the publication of such information by the maritime National Single Window could pose a threat to security.

9. The maritime National Single Windows shall have a uniform internet address.

10. The Commission shall adopt implementing acts laying down a harmonised structure for the support website referred to in point (d) of paragraph 3, technical specifications for making available arrival and departure times referred to in paragraph 8, and a uniform format for internet addresses referred to in paragraph 9. Those implementing acts shall be adopted in accordance with the advisory procedure referred to in Article 24(2).

The first such implementing act shall be adopted by 15 August 2021.
