Belgium & EU Systems Transition Pack
Master the switchover to PLDA, IDMS, AES, and NCTS
In 2026, Belgium is undergoing the largest customs IT transition in its recent history. We map your current flows, secure your migration to the new systems, and prevent any disruption to your customs clearance.
Why these customs developments concern you right now
It's no longer a question of "if", but "when". And delays cost you immediately: rejected declarations, blocked flows, overwhelmed teams, and partners who can't keep up with the new systems.
European customs systems are evolving rapidly — and directly impact your operations:
PLDA (being phased out)
The Paperless Douanes and Accises system is being gradually decommissioned (2024-2026).
-> Your legacy processes are becoming obsolete.
IDMS (import)
Import Duty Management System has been mandatory for certain flows since April 2026.
-> New requirements for your import declarations.
AES Phase 2 (export)
Automated Export System the export system evolves in 2026 with AES Phase 2.
-> Mandatory adaptation of your export declarations.
NCTS Phase 5 (transit)
New Computerised Transit System the new transit system becomes general in 2026.
-> Direct impact on your T1 / T2 operations.
ICS2 Release 3 (security)
Mandatory for all modes of transport.
-> Reinforced upstream controls on your flows.
CCI (import centralisation)
Centralised Clearance for Import — Belgium now allows the centralisation of import declarations (since 2025).
A strategic opportunity to steer your European flows.
Without adaptation, these developments become sources of blockage.
With structured steering, they become an operational advantage.
