ICS2 Explained: A Comprehensive Introduction for UK Businesses

The European Union’s Import Control System 2 (ICS2) represents a significant step forward in global trade compliance and security. For UK businesses operating under post-Brexit trade rules, understanding ICS2 is critical. This article outlines the purpose, scope, and practical impact of ICS2 on UK importers and exporters, highlighting how advanced cargo information fits into the EU’s broader risk-based approach to border controls.

1. What Is ICS2?

ICS2 is the EU’s updated framework for safeguarding its customs territory by requiring detailed, pre-arrival information on goods entering the Union. It replaces the older ICS1 model as part of the Union Customs Code (UCC) Work Programme, mandating an Entry Summary Declaration (ENS) for every shipment before it arrives in the EU.

Core Objectives

• Enhanced Security: ICS2 focuses on identifying high-risk goods, such as illegal or dangerous items, before they reach EU borders.
• Efficient Trade Flow: By leveraging advanced data analytics, customs authorities can fast-track legitimate goods and minimize disruptions.
• Global Alignment: ICS2 is part of an international move toward data-driven customs management, aligning with similar initiatives in other major economies.

For UK businesses, ICS2 applies whenever they send goods into the EU or facilitate supply chains destined for EU markets. Even though the UK has its own customs system post-Brexit, ICS2 compliance remains essential for any EU-bound shipment.

2. The Purpose of ICS2

At its core, ICS2 is a risk management tool. It requires economic operators to submit detailed cargo data electronically, allowing EU customs to:

1. Assess Security Risks: Evaluate each shipment’s risk profile well in advance.
2. Target Inspections: Reduce blanket checks by focusing on high-risk consignments, thus speeding clearance for low-risk shipments.
3. Prevent Illegal Trade: Identify and intercept weapons, counterfeit goods, or other contraband before they circulate in the EU.

Since Brexit, the UK is classified as a “third country” from the EU’s perspective. Consequently, shipments from the UK to the EU must align with ICS2 regulations, regardless of existing UK customs procedures.

3. Scope of ICS2: Phased Implementation

3.1 Phases of Deployment

ICS2 has rolled out in three main phases, each stage broadening the scope of transport modes or supply chain actors involved:

1. Phase 1 (March 2021): Applied to postal operators and express carriers focusing on air cargo.
2. Phase 2 (March 2023): Extended to all air carriers, freight forwarders, and air cargo handlers.
3. Phase 3 (June 2024 onward): Covers maritime, inland waterways, road, and rail, effectively encompassing all transport modes and remaining economic operators.

As of March 26, 2025, ICS2 is fully operational across all modes of transport, impacting any UK business whose goods enter EU territory.

3.2 Who Submits the ENS?

Under ICS2, the Entry Summary Declaration can be filed by carriers, freight forwarders, customs brokers, or other authorized Economic Operators (EOs). UK businesses must confirm which party in their supply chain will handle the ENS to avoid non-compliance. If data is missing or submitted late, shipments risk being delayed or refused at EU borders.

4. Advanced Cargo Information: The Key Requirement

Advanced cargo information is the linchpin of ICS2’s risk-based model. Prior to loading (for air transport) or arrival (for sea, road, rail), the ENS data must be transmitted electronically, typically including:

• Shipper and Consignee Details
• Accurate Goods Description (with six-digit HS codes)
• Quantity, Weight, and Packaging Information
• Transport Details (flight or vessel number, routing)
• Security Risk Indicators, if applicable

For air shipments, certain “pre-loading” data elements must be filed separately from “pre-arrival” elements. This granular approach enables customs officials to target high-risk shipments more rapidly.

5. ICS2 in the Post-Brexit Context

5.1 Dual Compliance for UK Businesses

Post-Brexit, goods moving between the UK and EU face two distinct customs regimes:

• UK customs controls under HM Revenue & Customs (HMRC).
• EU customs controls, which now include ICS2 requirements.

Even though the UK has a Trade and Cooperation Agreement (TCA) with the EU that largely removes tariffs on qualifying goods, it does not eliminate customs formalities. ICS2 adds a security-focused layer to these procedures, meaning UK exporters and freight agents must factor in additional data submission steps.

5.2 Potential Consequences of Non-Compliance

• Delays at EU Borders: Incomplete or incorrect ENS data can trigger cargo holds, increasing lead times and costs.
• Penalties and Fines: EU customs authorities may impose financial penalties for persistent violations.
• Reputational Risk: Frequent customs issues can damage relationships with EU customers and partners.

Meeting ICS2 obligations is therefore both a legal necessity and a commercial imperative.

6. Practical Steps for UK Businesses

1. Clarify Responsibilities: Determine who files the ENS—your business, the freight forwarder, or another supply chain partner.
2. Train Staff: Ensure your logistics and customs teams know the ICS2 rules, deadlines, and required data fields.
3. Update Systems: Use compatible software or platforms that can transmit advanced cargo information to the EU’s ICS2 interface.
4. Stay Informed: Monitor EU and UK government updates, especially as ICS2 guidance evolves with post-Brexit changes.
5. Collaborate with Experts: Engage customs brokers, freight forwarders, or consultants experienced in ICS2 to streamline compliance.
