If you import goods into the EU, the paperwork you file today runs through EU customs declaration systems that are already mid-overhaul. Some of that change is live: pre-arrival cargo data has been mandatory across every transport mode since 2025. Some of it is scheduled: a single EU Customs Data Hub is due to start replacing national IT systems from 2028. None of it is theoretical, and none of it waits for sellers who haven't updated their processes.
This isn't a story about decade-out technology bets. It's about the systems your freight forwarder, your customs broker, and your own compliance team are working with right now, and the ones due to land over the next few years.
CDS and National Declaration Systems: How EU Customs Actually Works
There's no single "EU customs computer." Each member state runs its own national declaration system: Germany uses ATLAS, France uses DELTA, Belgium uses PLDA, the Netherlands runs DMS, and Italy has AIDA. An import or export declaration you file for goods entering through Rotterdam goes through a different national system than one entering through Hamburg, even though both operate under the same Union Customs Code.
Sitting above these national systems is the EU's own Customs Decisions System (CDS) — not to be confused with the UK's separate Customs Declaration Service, which uses the same acronym but is a different system entirely. The EU's CDS handles applications and decisions that affect more than one member state: Authorised Economic Operator (AEO) status, customs simplifications, and other authorisations that need to be recognised across borders rather than filed once per country. It runs on shared EU infrastructure alongside the national components each member state still controls.
Why the Patchwork Creates Friction
For an importer selling across several EU markets, this patchwork means data formats, timelines, and even document requirements can differ depending on where a shipment first enters EU customs territory. A commercial invoice format accepted without question in one country's system may trigger a query in another. This is precisely the fragmentation the EU's reform agenda is aimed at fixing — more on that below.
The paper Single Administrative Document (SAD) that once standardised import, export, and transit declarations across the bloc has been giving way to fully electronic filings for years now, with each national system implementing its own version of the transition. France's DELTA system, for instance, replaced SAD-based import filings with a structured electronic message, while Germany's ATLAS follows a comparable but not identical logic. The underlying legal framework is shared under the Union Customs Code; the day-to-day filing experience is not.
ICS2 and the Shift to Pre-Arrival Cargo Data
The Import Control System 2 (ICS2) is the piece of customs technology that has changed the most in the last few years, and it's the one most likely to affect your shipments directly. ICS2 requires an Entry Summary Declaration (ENS) — advance data about a shipment's contents, parties, and routing — before goods physically arrive at the EU border, not after.
The rollout happened in phases. Release 1, from March 2021, covered postal operators and express couriers moving goods by air. Release 2, from March 2023, extended the requirement to general air cargo, freight forwarders, and consolidators. Release 3 brought maritime, road, and rail carriers into scope, with member states phasing out earlier transitional arrangements through 2025 and into 2026. The practical result: by 2026, an ENS filing is expected before arrival regardless of how goods enter the EU — by sea, air, road, or rail — and the older ICS1 system is no longer accepted for shipments that fall under ICS2.
What Release 3 Means for Freight Forwarders and Importers
The data burden under ICS2 sits mostly with carriers and freight forwarders, but importers feel the consequences when a filing is incomplete or incorrect. A missing HS code, an inconsistent consignee address, or absent EORI details can hold a shipment at the point of entry rather than in transit, where it's far harder to fix quickly. If you're routing goods through multiple EU entry points, it's worth confirming with your forwarder which member state's requirements apply at each one, since enforcement timelines for the final phase weren't identical across the bloc.
The ENS dataset required under Release 3 is also noticeably richer than what ICS1 asked for, covering more detail on the parties involved in a shipment and the goods themselves. That's a deliberate design choice: the whole point of pre-arrival data is to let customs authorities run risk analysis before a shipment reaches the border, rather than discovering a problem once it's already there. For a seller, this means the information you hand to your forwarder needs to be complete before dispatch, not patched together while the shipment is already in transit.
Where E-Invoicing Rules Now Intersect With Customs
VAT in the Digital Age (ViDA) is a separate reform from the customs changes above, but the two increasingly overlap for anyone moving goods and issuing invoices across EU borders. Under ViDA, mandatory Digital Reporting Requirements based on structured e-invoicing apply to cross-border B2B transactions from 1 July 2030. Some member states are moving faster on their own domestic timelines — Belgium and Poland already have e-invoicing obligations in force, while Germany and France are phasing in requirements through 2027 and 2028.
The connection to customs is direct: the commercial invoice data that feeds a customs declaration increasingly needs to match the structured, machine-readable format required for VAT reporting. An invoice built for one purpose but not the other creates a reconciliation problem at exactly the point where speed matters most — clearance.
Sellers who treat invoicing and customs documentation as separate workflows are the ones most likely to hit friction as these systems converge. Getting VAT numbers, legal entity names, and product classifications consistent across your invoicing platform and your customs paperwork isn't just good bookkeeping anymore — it's becoming a clearance-speed issue.
This matters most for sellers who already use the Import One-Stop Shop (IOSS) scheme for distance sales, since IOSS filings, VAT reporting, and customs declarations all draw on the same underlying transaction data. If one of those three shows a different value, weight, or product description than the others, it's the kind of discrepancy that customs risk-scoring is specifically designed to flag.
The EU Customs Reform and the Data Hub That's Coming
The biggest structural change is still ahead. In March 2026, the Council and Parliament reached agreement on a customs reform package described as the most significant since the Customs Union was created. Its centrepiece is the EU Customs Data Hub: a single portal intended to replace the current arrangement of separate national IT systems, so an importer logs product and supply-chain data once rather than adapting to each member state's own format.
Under the agreed timeline, the Data Hub becomes operational for e-commerce goods from 1 July 2028, with a phased rollout bringing all movements of goods into scope by 1 March 2034. A new EU Customs Authority, based in Lille, takes on risk-management and coordination duties starting 1 January 2028, working alongside — not replacing — national customs administrations. The reform also introduces a "Trust and Check" trader category: businesses that share sufficiently detailed, verified data may qualify for streamlined procedures, including release of goods with minimal active customs intervention.
Separately, EU finance ministers agreed to a flat customs handling charge on low-value parcels entering the EU from outside the bloc, addressing long-standing complaints that goods under the previous duty-free threshold competed unfairly with EU-based sellers. If your supply chain includes low-value parcel shipments from outside the EU, this is worth checking against your current landed-cost assumptions rather than relying on older thresholds.
What "Trust and Check" Status Could Mean for Your Import Flow
None of this is mandatory yet for most importers — the Data Hub's e-commerce phase doesn't start until mid-2028, and full mandatory use for all traders stretches out further still. But the direction is clear: cleaner, more complete, more structured data submitted earlier is what the whole reform rewards. Building that discipline into your current processes now, while the older national systems are still the primary route, puts you ahead of the transition rather than scrambling to catch up when the Hub opens to your traffic.
How to Prepare for These Changes Now
A few practical steps hold up regardless of exactly when each phase of reform lands:
- Confirm your EORI registration is current and matches the entity name used on your commercial invoices, since mismatches are a common cause of ENS and declaration rejections.
- Audit your invoice data fields against both customs and e-invoicing requirements, rather than treating them as two separate document types built for two separate audiences.
- Ask your freight forwarder or customs broker which national system handles your typical entry points, and confirm they're tracking ICS2 and reform-related changes on your behalf rather than assuming it's covered.
- Keep documentation for HS code classification decisions, since the shift toward data-driven, risk-based customs control puts more weight on demonstrable accuracy than on paperwork volume.
None of these steps require waiting for the Data Hub to go live. They reduce friction under the systems in use today and put you in a stronger position as the EU builds toward a more centralised customs framework — a shift covered in more depth in our look at ICS2 data quality and filing requirements.
If your business also handles cross-border e-commerce fulfilment, it's worth reading through our checklist of what to confirm before your first EU customs entry, which walks through the documentation, registrations, and broker relationships worth having in place before goods move.
Getting the Documentation Chain Right, End to End
Customs technology only helps if the information behind it is accurate. FLEX. handles import and export customs clearance across the EU as part of a wider service that also coversfreight forwarding into Amazon's European network and combined B2C and B2B fulfilmentfor sellers operating across multiple EU markets. For sellers who also run Amazon channels, our Help Center has a practical guide to international shipping and customs requirements for B2C e-commerce, including IOSS, which covers how the IOSS scheme interacts with import declarations.
The systems described above will keep evolving between now and 2034, but the fundamentals — accurate EORI details, consistent invoice data, and correct HS codes — stay the same regardless of which portal you're submitting them through.
Getting that foundation right now is the best preparation for whichever phase of the reform reaches your shipments next.
