Customs and compliance — May 2026
What is an ENS (Entry Summary Declaration)?
An ENS is a safety and security declaration submitted to customs authorities before goods arrive, covering both the EU and the UK. It's separate from the customs (import) declaration — its purpose is to give border authorities advance information about what's arriving and from where, for risk assessment, not to calculate duty.
For road freight, the ENS is typically tied to the means of transport, and the deadline for submission is short — often just before the vehicle departs or arrives, depending on the mode and route.
ICS2 and the EU's phased rollout
ICS2 (Import Control System 2) is the EU's platform for receiving ENS data, rolled out in phases across different transport modes — air cargo first, then maritime and inland waterway, then road and rail. Each phase brought more shipment types into scope, with more detailed data requirements than the system it replaced.
If a shipment type that previously didn't need detailed pre-arrival data now does, that's usually because the relevant ICS2 phase has come into effect for that mode — not because a new rule was introduced specifically for that cargo.
Who is the economic operator, and why does it matter?
Customs declarations — including ENS — are legally tied to an economic operator: the business identified as responsible for the data submitted. Depending on the contractual arrangement, that might be the carrier, the freight forwarder, or the importer/exporter themselves.
This matters because the economic operator's EORI number is what the declaration is filed against, and that business carries the compliance responsibility for the data being correct. On a multi-party shipment — producer, forwarder, haulier, consignee — it's worth being clear in advance about which party's EORI is being used and who is filing on their behalf.
What happens when ENS or ICS2 data is missing or wrong
Because ENS data feeds into automated risk-assessment systems, incomplete or inconsistent data is one of the more common triggers for a shipment being flagged for additional checks — even if the underlying goods and customs declaration are entirely in order.
The practical fix is almost always the same: make sure the party responsible for filing the ENS has accurate, complete commercial data well before the deadline, not assembled at the last minute from whatever documents happen to be available.
How Alvora manages pre-arrival declarations
Because our customs team works inside the same operation that plans transport, ENS and ICS2 data is prepared from the same shipment information used for the customs declaration — not recreated separately by a different party. This is part of our wider customs services, and we cover the documents that often accompany these declarations in our guide to customs documents explained. If you'd like to understand how this applies to your routes, get in touch.
Frequently asked questions
Does every shipment need an ENS?
In general, yes — goods entering the EU or UK customs territory require an ENS, with some specific exemptions for certain low-risk movements. Which exemptions apply depends on the transport mode and route, so it's worth confirming for your specific shipment type rather than assuming.
Is ICS2 the same thing as ENS?
Not quite — ICS2 is the EU's IT platform that receives ENS data. 'ENS' refers to the declaration itself; 'ICS2' refers to the system it's submitted through, which was rolled out in phases by transport mode.
Who decides which economic operator's EORI is used for a declaration?
It depends on the commercial arrangement between the parties — typically whoever is contractually responsible for the customs formalities for that shipment. This should be agreed and confirmed before the shipment moves, since it determines whose compliance record the declaration sits against.
