Preparing for ICS2 Compliance: Essential Steps for UK Traders
As international trade regulations evolve, businesses must keep pace—or risk falling behind. One of the most pressing developments in cross-border trade is the EU Import Control System 2 (ICS2), a major regulatory initiative that affects anyone importing goods into the European Union.
For UK traders, adapting to ICS2 isn't optional—it's a critical compliance requirement. With the UK now operating outside the EU's customs union post-Brexit, traders are treated as non-EU entities, making compliance with ICS2 mandatory for all shipments into EU territory.
This guide explores the essential steps UK traders must take to comply with the EU Import Control System 2. From understanding HS codes and submitting pre-arrival data to assembling a knowledgeable compliance team, we’ll walk you through everything you need to know to stay compliant and avoid costly disruptions.
What Is the EU Import Control System 2 (ICS2)?
The EU Import Control System 2 is an enhanced customs pre-arrival safety and security program introduced by the European Commission. Replacing its predecessor (ICS1), ICS2 is designed to collect and analyze advanced cargo information on goods entering the EU.
The purpose of ICS2 is to:
Strengthen customs risk management
Protect EU citizens from dangerous or non-compliant goods
Enable faster customs clearance
Improve supply chain transparency
At the heart of ICS2 is the Entry Summary Declaration (ENS)—a document that must be submitted electronically before goods arrive at the EU border. This allows customs authorities to screen shipments in advance and ensure that high-risk consignments are properly assessed.
Why ICS2 Compliance Is Critical for UK Traders
Post-Brexit, the UK is classified as a third country, meaning all goods exported from the UK to the EU fall under ICS2 rules. Failure to comply with ICS2 can lead to:
Shipment delays
Additional customs checks
Fines or rejections at the border
Reputational damage
For businesses relying on timely delivery and customer satisfaction, these risks are unacceptable. That's why UK traders must take proactive steps to prepare for ICS2 compliance.
Key Compliance Requirements Under ICS2
Understanding the core components of ICS2 is the first step toward compliance. Here's what UK traders need to focus on:
1. Proper Use of HS Codes
Harmonized System (HS) codes are essential for classifying traded goods. ICS2 requires traders to provide accurate HS codes in ENS filings to help customs authorities assess the nature and potential risk of goods.
Best Practices:
Use 6-digit HS codes at minimum (some EU countries may require 8-digit).
Cross-check HS codes against EU customs databases.
Train your team to identify and update HS codes regularly, especially when new products are added to your inventory.
Incorrect or vague HS codes can result in customs delays or penalties, so accuracy is non-negotiable.
2. Pre-Arrival Data Submission (ENS Filing)
The Entry Summary Declaration (ENS) must be submitted electronically prior to goods arriving at the first EU port of entry.
ENS must include:
Shipper and consignee details
HS code and product description
Total number of packages
Mode of transport and routing information
Safety and security data
The timing of the submission depends on the mode of transport:
Air cargo: ENS must be submitted before loading at the airport of departure.
Sea freight: Must be submitted 24 hours before loading.
Road and rail: Deadlines vary but will be mandatory in ICS2 Phase 3 (2025).
Pro Tip:
Automate ENS data submissions using logistics software that connects directly to the EU Shared Trader Interface (STI) to reduce errors and ensure timeliness.
3. Critical Documentation Checklist
Besides ENS, UK traders must ensure that all supporting documentation is accurate and available. This includes:
Commercial Invoice – detailing value, origin, and buyer/seller info.
Packing List – itemized list of packages and contents.
Bill of Lading (B/L) or Air Waybill (AWB) – for transport tracking.
Export Declarations – filed with UK customs (e.g., via CDS).
Import Licenses or Certificates – if applicable for restricted goods.
Missing or mismatched documents can trigger red flags in the ICS2 system, resulting in unnecessary delays.
Assembling the Right Compliance Team
Successful ICS2 compliance requires a collaborative internal effort. Assembling the right team is crucial to manage data accuracy, system integration, and regulatory updates.
Roles to Include:
Customs Compliance Officer Oversees ICS2 regulations, HS codes, and documentation accuracy.
Logistics Manager Coordinates with carriers and freight forwarders for timely ENS submissions.
IT/System Administrator Ensures your digital infrastructure can interface with customs portals.
Operations Manager Aligns ICS2 compliance with production and shipping schedules.
External Consultant or Customs Broker (optional but recommended) Offers expert support and can manage filing obligations on your behalf.
Steps to Achieve ICS2 Readiness
1. Audit Your Supply Chain
Review all shipping routes, transport modes, and stakeholders to identify where ICS2 obligations apply. This helps map out who is responsible for submitting ENS data.
2. Clarify Responsibilities With Partners
Freight forwarders, carriers, and brokers may share responsibility for ENS filings. Clearly define who submits what, and when.
3. Upgrade Internal Systems
Implement or upgrade your Enterprise Resource Planning (ERP) or logistics software to support data automation and integration with EU systems.
4. Conduct Staff Training
Educate your logistics, customs, and sales teams about ICS2 timelines, requirements, and penalties. Consistency across departments ensures smoother compliance.
5. Test With Real Shipments
Once your systems and processes are in place, test ENS submissions using actual shipment data to identify any gaps before the regulations are fully enforced.
Future-Proofing: Preparing for ICS2 Phase 3 (2025)
ICS2 is being implemented in three major phases:
Phase 1 (2021) – Postal and express shipments via air.
Phase 2 (2023) – General air cargo.
Phase 3 (2025) – Maritime, rail, and road freight.
If you ship goods via sea, rail, or road, you’ll be impacted by Phase 3, launching in March 2025. Now is the time to prepare for broader compliance obligations and higher data accuracy requirements across all modes of transport.
