At the heart of ICS2 is the requirement for advanced electronic submission of Entry Summary Declarations. These declarations are far more detailed than their predecessors. They require not just transport information, but also specific consignment level data such as the 6-digit HS code, the EORI number of the consignee, and a clear description of the goods. Generic labels like "parts" or "samples" are no longer acceptable.

Another fundamental change is the multi-filing approach. Unlike the previous system where a single party typically submitted the ENS, ICS2 allows multiple entities such as carriers and freight forwarders to submit parts of the same declaration. This modular filing model means coordination between supply chain actors is more critical than ever.

To facilitate these submissions, the EU has launched a centralised platform known as the Shared Trader Interface (STI). Operators must either integrate their systems with the STI or access it through the EU Customs Trader Portal, which requires registration through the Self-Service Portal (SSP). Without these steps, traders won’t be able to legally submit the necessary data, potentially holding up shipments at the border.

The penalties for non-compliance with ICS2 go beyond administrative headaches. Submitting incorrect or incomplete information can lead to customs authorities blocking cargo from being loaded at the origin, detaining goods upon arrival, or issuing financial penalties. For just-in-time supply chains, these disruptions can have ripple effects far beyond a single missed delivery.

Phase 3 of ICS2 will significantly affect international road hauliers, and rail logistics operators. All of them must begin aligning their systems, staff, and workflows with ICS2 requirements immediately. Given the complexity of shipping documentation and the often-fragmented nature of the transport industry, this will likely require internal audits, IT upgrades, and enhanced communication with third-party logistics providers.

We're excited to announce that we’re working on a new CABIE ICS Portal to make it easier for you to submit your ICS2 Safety and Security declarations for goods entering the EU. Whether your goods are moving as accompanied or unaccompanied through GVMS ports, this new portal has you covered.

You’ll be able to pull in data straight from an Export Accompanying Document (EAD). If you’re already using CABIE with a UK EORI number, you can simply enter the MRN. Either way, it’s a quick and straightforward way to get your consignment details into the declaration.

When to submit 

Depending on the type of transport or shipping service you have used, there are different time limits for submitting your declaration. 

Submission Response Times

• After submitting an ENS declaration, it may take up to 20 minutes, to receive a response. During this time, the status will appear as In Progress.
• Patience is key—avoid re-submitting declarations unless the status remains unchanged after a significant period.
• We recommend you submit your declaration as early as possible to avoid the time limit, response times may take longer during peak periods.

HMRC Service Availability

• To ensure smooth submission, you can check the HMRC service availability for S&S (Safety & Security) **HERE** for any ongoing disruptions or planned maintenance.
