Import Control System 2 (ICS2) is an advance cargo information system designed to improve security in the international transportation of goods and involved supply chain. All Economic Operators (EOs) that bring goods to or transiting through the EU, have to declare safety and security data to ICS2, through the Entry Summary Declaration (ENS). Based on the ENS, all goods are subject to safety and security risk analysis and better targeted controls.
ICS2 helps to better identify high-risk consignments and intervene at the most appropriate point in the supply chain, while facilitating legitimate flow of goods.
Latest News
Start of application of the new version (v3) of ICS2 messages as of 3 February 2026, and decommissioning of previous version (v2).
Following the deployment of ICS2 software release 3.1.0.0 on 19 July 2025, previous version (v2) of messages IE3F10, IE3A10, IE3F13, IE3A13, IE3F17, IE3A17, IE3F34, IE3A34, IE3F40, IE3A40, IE3F41, IE3A41, IE3F45, IE3A45, IE3F50, IE3A50, IE3F51, IE3A51, IE3Q05 will be decommissioned on 3 February 2026.
As of 3 February 2026, only the new version (v3) of these messages will be used. If ENS filings lodged using the above messages in v2 prior to 3 February 2026 will need to be amended after that date, amendments will not be possible. The ENS filings will have to be invalidated, and the data will have to be re-lodged using v3 messages.
For this reason, it is recommended that economic operators affected by the change implement the new version (v3) of the messages well in advance before the cut-off date of 3 February 2026.
Practical guidance applicable from 1 September 2025 following full deployment of the ICS2 for all means of transport, including road and rail.
Member States have declared that businesses in rail and road transport are ready to apply the new EU customs border security rules as from 1 September 2025. However, several EU Member States and the United Kingdom (in respect of Northern Ireland) have requested temporary extensions to the implementation deadline. These derogations would ease the transition for economic operators, especially small enterprises, as they adapt to the new rules. In certain Member States, the derogations would include the possibility to continue to file security data combined with the transit declaration via New Computerised Transit System Phase 5 (NCTSP5). The document below explains the current situation for each Member State and provides guidance on how to submit the required safety and security data during any applicable derogation period:
- Recording of the ICS2 STI-STP portal training that explains how to connect to STI-STP portal and how to submit ENS filing has been published in the publicly available CIRCABC ICS2 group ICS2_Library. Title of the file: (20250702)-ICS2 STI-STP training.
- ENS filings are rejected in case of insufficient data quality. Economic Operators must monitor their error messages and re-submit filings with accurate data. A non-exhaustive list of stop words is available in CIRCABC.
- Air cargo information - Filing accurate and complete ENS data is key to remain ICS2 compliant
European Commission would like to remind economic operators to strictly adhere to the ICS2 filing instructions to ensure compliance to the legal requirements and avoid potential delays and penalties. To achieve this, it is essential that ENS filers provide accurate and complete data for every shipment at both master and (lowest) house levels.

How to prepare
To connect to ICS2, Economic Operators have to obtain an Economic Operators Registration and Identification (EORI) number from one of the EU Member States’ customs authorities. They also have to develop the necessary IT and business processes and successfully complete the mandatory self-conformance test.
To meet the ICS2 ENS data filing obligations, Economic Operators can decide to either develop their own IT system for this purpose or use the services of an IT Service Provider (ITSP).
ENS filings can be submitted through the Shared Trader Portal (STP). To access and connect to STP, the sender of the ENS needs to be registered in the national/central Unified User Management and Digital Signatures (UUM&DS) system. You can find more information about UUM&DS on EU Customs Trader Portal. Alternatively, Economic Operators may choose to develop their own IT system and connect directly to ICS2 via Shared Trader Interface (STI). In this case, mandatory self-conformance testing must be completed before GO-LIVE.
For technical preparation related to ENS filing, please see the relevant Technical Factsheet.
All necessary documents for conformance testing and ICS2 implementation are available in the publicly available CIRCABC EU Advance Cargo Information System (ICS2) Interest group.
According to the Implementing Decision on the Union Customs Code (UCC) Work Programme (Commission Implementing Decision (EU) 2023/2879), the ICS2 go-live date has been revised, and the possibility for the Economic Operators to receive deployment windows, depending on the mode of transport, have been agreed.
For road and rail, economic operators need to start using ICS2 for ENS filing from 1 April 2025.
Economic operators who are not ready by this date are strongly encouraged to contact the National Service Desk of the EU Member State (National Customs Authority) where their EORI number is registered to request a deployment window at least one month (1 March 2025) before the go-live date scheduled for their transport mode. The deployment window is not applicable by default (without a request issued by the Economic Operator).
Further information about the procedure of granting a deployment window can be found in the “ICS2 Release 3 Go-Live procedure for Economic Operators” document published in CIRCABC.
How ICS2 works
- Economic Operators need to submit a complete Entry Summary Declaration (ENS) in the ICS2 system for all goods transported to or through the EU prior to their arrival. For air transport, a minimum set of information must also be filed prior to loading (pre-loading phase).
- A complete ENS shall contain all required data elements specific to the mode of transport or business model.
- Depending on the contractual arrangements among supply chain actors regarding ENS filing responsibilities and the availability of information, either single or multiple ENS filings may be used.
- Based on the information provided in the ENS, customs authorities perform pre-loading or pre-arrival safety and security risk analysis.
- As a result of risk analysis, risk mitigating referrals might be issued requesting the declarant to provide additional information, perform high risk cargo and mail screening or not to load the cargo. The risk mitigating referrals must be answered before the risk assessment can resume.
- Operator of a sea-going vessel or of an aircraft must lodge an arrival notification upon the arrival of the means of transport at the Customs office of first entry.
- Goods must be presented to customs upon their arrival.
- Customs may also decide to impose administrative sanctions for non-compliance with data requirements.

Publication metadata
If you are transporting goods (including postal consignments) into or via the EU, Northern Ireland, Norway, or Switzerland by road, you will have to submit new safety and security data prior to the goods’ arrival.
The EU customs authorities may reject incomplete ENS declarations or issue risk mitigating referrals in the pre-loading or pre-arrival phase requesting the declarant to provide the necessary data, for example in the case data will not be accurate.
This might create delays in processing of the ENS upon the arrival of the consignments and in the entry process.
