EU deploys NCTS Phase 6 for combined transit and safety filings

The New Computerised Transit System now operates in the 27 EU Member States and the countries of the Common Transit Convention, covering 41 participating countries. Phase 6 links transit processing with Import Control System 2 requirements for pre-arrival safety and security data. It is an operational customs-system deployment under the Union Customs Code work programme, not a new customs duty or a change to tariff rates.^[1][2]

Two filing models depend on the country

Each participating customs administration chooses an opt-in or opt-out model. Under opt-in, a trader may include Entry Summary Declaration particulars in the transit declaration and NCTS connects to ICS2 for risk analysis, control recommendations and decisions. Under opt-out, the transit declaration remains in NCTS while the ENS is lodged separately in ICS2. Only a complete ENS can be combined with the transit declaration, and a country may change from opt-out to opt-in later.^[1][2]

Transit controls and guarantees remain

NCTS continues to manage Union and Common Transit movements for goods whose customs and excise duties and trade-policy measures are suspended during transit. A declaration identifies the goods, parties, transport and route, and the holder must provide a valid guarantee. Acceptance generates a Master Reference Number used to track the movement. Phase 6 simplifies the safety-data channel in opt-in countries; it does not remove transit, guarantee, presentation or control obligations.^[2]

Groups need country-specific readiness

Importers, exporters, carriers and customs brokers should map their transit routes against the Commission's NCTS Phase 6 state-of-play list and confirm whether each relevant customs administration uses opt-in or opt-out. Filing software and broker instructions should prevent an incomplete ENS from being embedded in a transit declaration and should preserve the separate ICS2 route where required. The Commission says the opt-in model can reduce duplicate filing and improve validation, but the practical workflow is not uniform across the 41-country network.^[1][2]

The Commission's NCTS page identifies Commission Implementing Decision (EU) 2023/2879 as the UCC work-programme instrument for the electronic systems and describes the NCTS–ICS2 interface through the Transit ENS Data Processing Bridge. Groups should therefore treat 26 October as the verified deployment milestone while continuing to follow national implementation instructions and later changes to each country's selected model.^[2]
