The Maritime National Single Window (MNSW) introduces the national elements of the European Maritime Single Window environment (EMSWe), which will enable all ship reporting to be done to one contact point per Member State. The Swedish Maritime Authority is responsible for this point of contact. It will be possible to submit required for customs purposes, i.e., notification of arrival of goods and temporary storage, using this single point of contact.The Swedish Environmental Protection Agency is the competent authority in Sweden.
The implementation in Sweden is scheduled for Q3, 2027. The MNSW will then replace the Maritime Single Window (MSW), the current system. AS per the EMSWe Regulation, the launch date of the MNSW was 15 August 2025. The impact of this change in the timetable on customs formalities in the form of presentation notifications and temporary storage in the maritime flow is being analysed. For the time being, the existing transitional solution is used.

PoUS Phase 2 includes manifests for customs purposes, also known as Customs Goods Manifest, CGM. The plan is for the CGM to be fully implemented at the same time as the MNSW (Maritime National Single Window) – the future digital interface for reporting in maritime transport. The intention of the CGM is for data submission to be integrated with the MNSW. The information is then automatically forwarded to the PoUS system, which is managed by the EU customs authorities.
