Five EU states face ICS2 road deadline on 1 June 2026

Croatia, Latvia, Poland, Romania and Slovakia must complete their move to the EU Import Control System 2 for road freight by 2026-06-01, closing a temporary derogation that has kept the older ICS1 system in place. After that date, any carrier filing under ICS1 will see shipments stopped at the EU customs office of first entry rather than receive a warning, according to guidance issued by IRU and a CLECAT advisory circulated in early May 2026.

Which countries fall under the 1 June 2026 deadline

The five member states cover much of the EU's eastern and southern road-freight corridors. Poland is the bloc's largest road-freight nation by tonne-kilometres; Romania and Slovakia gateway most Black Sea and Western Balkans flows; Croatia anchors a Mediterranean entry route; and Latvia handles a sizeable share of Baltic-to-EU movements. Austria, Germany, Denmark and other states have already been operating under ICS2 for road since September 2025, which means 2026-06-01 closes the last temporary derogation the European Commission Taxation and Customs Union directorate had granted to allow these five markets more preparation time. From that date, ICS1 is fully decommissioned across all modes and all member states.

What carriers must do before the deadline

The operational rule is unchanged from earlier ICS2 waves. An Entry Summary Declaration must be submitted and accepted at least one hour before the vehicle reaches the customs office of first entry. A non-compliant or missing ENS does not generate a warning under ICS2 version 3, it generates a stopped shipment. Industry guidance from Customs-Declarations.UK and from Maersk's compliance team both stress three priorities for the next two weeks: confirm the carrier's EORI (Economic Operators Registration and Identification) registration is current, audit the data flow from consignor and consignee so that all mandatory ENS fields are populated, and align with software providers or appointed agents on how the submission will be triggered for every cross-border movement. Operators that already run regular cabotage (domestic deliveries by a foreign-flagged operator) into these markets should review Logifie's explainer on the EU Mobility Package cabotage and posting rules , since compliance with both regimes runs in parallel.

Why the ICS2 multiple-filing gap matters

ICS2 version 3 introduces a multiple-filing model that lets the carrier, the freight forwarder and the trader each contribute partial ENS data to a single declaration. That model is not yet in force. Until the European Commission completes the rollout, expected in the second half of 2026 following IRU advocacy, single filing remains mandatory. In practice that means one party, almost always the road carrier or its appointed agent, is solely responsible for collecting every required data point from upstream parties and submitting one comprehensive ENS for each consignment. The data-collection burden is where most operational risk concentrates, and where most stopped-shipment cases will land in the first weeks of June 2026 if pre-deadline audits are skipped.

Carriers planning runs into Croatia, Latvia, Poland, Romania or Slovakia in the second half of May 2026 should treat the next two weeks as the audit window.
