New Computerised Transit System (NCTS) 

A Europe-wide digital system for better management and control of goods under Union and Common Transit

New Computerised Transit System

The New Computerised Transit System (NCTS) is a Europe-wide digital system designed to provide better management and control of goods under Union and Common Transit. It involves all EU countries and Common Transit Convention (CTC) contracting parties. Based on transit declarations, NCTS processes safety and security data for entry and exit formalities. 

NCTS comprises interconnected national applications which exchange messages on a common network. These messages are exchanged electronically on three levels: 

  • between the economic operators and customs (‘external domain’); 
  • between customs offices of one country (‘national domain’);  
  • among the national customs administrations themselves and with the Commission (‘common domain’). 

Why is NCTS important?

NCTS facilitates the movement of goods between two points in the customs territory of the Union (CTU) while passing through or ending in an area outside that customs territory. In this process, there is no change in the customs status of those goods. NCTS also enables Common Transit, which facilitates the movement of goods between CTC contracting parties.

History of NCTS

In 1997, the Commission adopted an action plan to reform the transit system in Europe. This reform aimed to recreate a balanced, realistic and trustworthy transit system for economic operators and customs authorities. 

One major pillar of this action plan was the development of a New Computerised Transit System (NCTS) to better monitor, streamline and speed up transit processes. NCTS was launched in 2004 and became mandatory for Union and Common Transit in 2005. 

NCTS has been released over several phases. Phase 4 was released in 2009, and Phase 5 is currently being implemented, with a full deployment date of 2 December 2024.

Transition to NCTS-P5

Impact of transition from NCTS-P4 to –P5 on business processes 

NCTS Phase 5 has several new features: the alignment of information exchanges with Union Customs Code (UCC) data requirements, the upgrade and synchronisation of interfaces with other systems for better supervision when several procedures and systems are involved, and other new functionalities. 

The table below summarizes the impact of the transition from P4 to P5 on the business processes:

  • The first step of implementation covers NCTS’ core functionalities. It ensures operational continuity of the system through a standard transit declaration (core flow), simplified procedure at departure/destination (authorised consignor/consignee), amendment/invalidation, diversion (at transit and destination offices), inquiry/recovery processes and the sending of business statistics. It may also cover non-core functionalities. The deadline for National Customs Administrations to deploy this first step was 1 December 2023. 
  • The second step covers newly introduced NCTS-P5 functionalities such as the development of an interface harmonised with Automated Export System (AES), declarations lodged prior to the presentation of goods, declarations with reduced datasets, incidents ‘en route’, and formalities for the office of exit. Some countries have chosen to develop and deploy the first and second step together in one go. The deadline for full implementation of NCTS-P5 is 2 December 2024. 

For more information on AES implementation, please consult the UCC Work Programme.

Impact of the transition from P4 to P5 on the business processes

Prepare for NCTS-P5

To correctly deploy NCTS-P5, it is important for national authorities to strictly follow the latest available technical specifications. This ensures harmonised implementation across authorities. 

Particular attention must be paid to conformance testing. This ensures business continuity and enables a reliable product capable of processing exchanges between NCTS countries. Planning for conformance testing is crucial, since this activity can take a significant amount of time. 

It is also important to maintain close contact - both between customs administrations and with the trade community - so that all relevant stakeholders are informed about the steps that national authorities are taking.

New features in NCTS-P6

NCTS-P6 will be released in March-September 2025. It features specific requirements for safety and security data in transit customs declarations of goods brought into the Safety and Security Area (SSA) of EU countries plus Norway and Switzerland. 

NCTS-P6 is divided into two approaches: opt-in and opt-out. 

  • By opting in, a country chooses to connect to ICS2 via the Transit ENS Data (TED) Processing Bridge, a converter that helps communicate ENS data to ICS2 (Article 130(1), UCC). This link with ICS2 means that economic operators (EOs) can now submit only one declaration, instead of two separate ones to NCTS and ICS2. 
  • By opting out, a country chooses not to connect to ICS2. Therefore, ENS data cannot be used by NCTS. Nevertheless, these countries must update their systems to NCTS-P6 specifications. A country may later decide to move from opt-out to opt-in.

How does NCTS work? 

Transit declarations include information on items carried, their sender and recipient, the mode of transportation, the intended route and the customs offices engaged. The holder of the transit procedure must also provide a valid guarantee. 

When a transit declaration is accepted, NCTS generates a unique ID called the Master Reference Number (MRN). The MRN enables the product’s movement to be tracked throughout its transportation procedure. Customs officers in each customs office can track the movement of goods via NCTS to ensure that they travel on the authorised path.

NCTS and transit movements

There are several forms of transit movements which require processing via NCTS:
