DELTA T.
Customs Transit Declaration

Introduction to Delta T

What is the Customs Transit Declaration (Delta T)?

DELTA-T is an online service for managing transit declarations. It replaces the previous two applications, NSTI and NSTI Nlle PR, and is now responsible for tracking transit declarations and transit search procedures. Launched in 2014, the overhaul of the NSTI and NSTI Nlle PR systems was completed in November 2021 with the launch of Delta T, marking the transition of all operators and country flows to this new system.

The transition from NSTI to DELTA T took place at the beginning of 2022, with several notable improvements. Among the new features, there is the ability to declare a transit up to 30 days before the actual departure, as well as covering one or more packages transported together on the same means of transport. DELTA T also integrated a regulatory and technical upgrade in preparation for NCTS Phase 5. In addition, the system now allows 24/7 notifications to an authorized recipient, and offers the possibility to request the correction or invalidation of the declaration digitally.

Importance of Delta T for Commercial Operations

From the submission of the declaration to the removal authorization, through the notification at the time of passage and controls, these declarations facilitate the movement of goods through suspension of duties and customs taxes. They are valid within the European Union countries as well as in the countries signatories to the Transit Convention.

Objectives of the Transport Declaration

Compliance with Customs Regulations

Delta T ensures that the transit procedures comply with the applicable customs legislation, thereby ensuring that legal obligations are met by economic operators.

Facilitation of customs clearance procedures

By simplifying and automating the transit declaration process, Delta T accelerates the customs clearance of goods and reduces processing times, thus improving business operation efficiency.

Optimization of security and quality controls

The system strengthens security controls by enabling better traceability of goods and more rigorous management of transit procedures, thereby contributing to fraud prevention and the protection of economic interests.

Transport Declaration Process

The declaration process under Delta T is structured as follows:
  1. Creation of the Declaration: The declarant submits a transit declaration via the Delta T system. This declaration must include detailed information about the goods, their origin, their destination, and the transport method used.
  2. Validation and Control: Once the declaration is submitted, it is checked and validated by the customs authorities. This step may include compliance and security checks.
  3. Notification at the Time of Passage: When the goods pass through the border, a notification is sent to the approved recipient, informing them of the status of the declaration and the progress of the transit.
  4. Release Authorization: After verification and control, the customs authorities issue a release authorization, allowing the goods to continue their journey or be released.
  5. Management of Rectifications: In case of errors or necessary modifications, the declarant can submit a correction request or invalidate the declaration electronically through the Delta T system.
