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.
More information about the bi-monthly technical-operational webinars is available on CIRCABC.

Reminder to the Economic Operators on the urgency to complete the v2 to v3 transition not to be blocked when the v2 decommissioning happens
Updated version of the stop words list available as of 2 February 2026 has been published in the CIRCABC library.
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.
This guidance explains the requirements to lodge an ENS during the transitional period between 1 September 2025 and until the end of the derogation period granted individually to a Member State. Derogations can be granted for different durations.
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.
ICS2 STI-STP portal training is available in the ICS2_Library.
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.
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.
