The final transition to Import Control System 2 (ICS2) Entry Summary Declaration (ENS) requirements is now complete. As of 1 June 2026, all applicable Entry Summary Declarations must be submitted through the ICS2 framework across the European Union, Northern Ireland, Norway and Switzerland. Please click here to see the official announcement on this topic.
The transition period has officially ended. There are no remaining derogations or exceptions, and ICS1 is no longer accepted for applicable shipments. Businesses involved in international trade should ensure their processes are fully aligned with ICS2 ENS requirements to avoid shipment delays, additional Customs controls, and supply chain disruption.
What Changed on 1 June 2026?
ICS2 Release 3 marked the final phase of Europe’s transition to the new Customs security framework. While most businesses had already migrated to ICS2 ENS, temporary derogations remained in place for certain road and rail movements involving Croatia, Latvia, Poland, Romania and Slovakia.
Those derogations have now expired.
All Entry Summary Declarations covered by the regulation must now be submitted through the ICS2 ENS framework. The phased transition has concluded, and the new requirements now apply across all participating countries without exception.
What Is ICS2 ENS?
Import Control System 2 (ICS2) is the European Customs security system that enables Customs authorities to receive shipment information before goods arrive. This allows security and safety risks to be assessed earlier in the supply chain, supporting more effective risk management while helping legitimate trade move more efficiently.
For businesses, the focus is on submitting accurate, complete and timely shipment data. High quality information enables Customs authorities to complete their assessments before cargo reaches the border and helps reduce the risk of unnecessary delays or intervention.
Key Compliance Requirements
With the transition period complete, businesses should review their filing processes to ensure they continue to meet ICS2 ENS requirements.
Key considerations include:
- Accurate shipment data. Entry Summary Declarations must contain complete and accurate information. Missing or incorrect data may result in requests for additional information, shipment delays, or increased Customs scrutiny.
- Timely ENS submission. Declarations must be submitted within the applicable filing deadlines before goods arrive in the relevant Customs territory. Filing timelines vary depending on the mode of transport.
- Supply chain coordination. ICS2 compliance depends on effective collaboration between carriers, freight forwarders, importers, exporters, logistics providers and Customs representatives. Each party has a role in ensuring the required information is available and submitted correctly.
Consequences of Non Compliance
With all derogations now expired, Customs authorities will apply ICS2 ENS requirements across all applicable shipments.
Businesses that fail to meet their obligations may face:
- Shipment delays
- Additional Customs inspections
- Goods being held at the border
- Refusal of loading or movement
- Increased administrative workload
- Higher operational costs
- Supply chain disruption
Reviewing internal processes and ensuring data quality remain essential for maintaining efficient cross border operations.
