Import Control System 2 (ICS2) is the EU’s advance cargo information system. Economic operators submit Entry Summary Declaration (ENS) data before goods arrive in—or transit—the EU customs territory so customs authorities can perform safety and security risk analysis.
As of 1 June 2026, consignments entering the EU by any means of transport should have a valid ENS submitted directly to ICS2 or, in participating countries and eligible road or rail flows, through a combined NCTS Phase 6 transit declaration. Retailers do not necessarily file the ENS themselves, but they must provide accurate product and party data to the actor responsible for filing.
ICS2, ENS and EAD: what is the difference?
| Term | Meaning | Why it matters |
|---|---|---|
| ICS2 | The EU system that receives advance cargo information and supports safety and security risk analysis. | It is the system and process environment, not a single document supplied by the retailer. |
| ENS | The Entry Summary Declaration containing required pre-arrival or pre-loading data. | Incomplete or inaccurate data can trigger rejection, referrals or delays. |
| EAD | Electronic advance data supplied through the logistics chain. | Retailer product and customer data help the filing party create an accurate declaration. |
| EORI | An Economic Operators Registration and Identification number. | Economic operators connecting to ICS2 need an EORI issued by an EU Member State customs authority. |
What data should an ecommerce seller prepare?
- Clear goods description: describe what the item is, not a vague label such as “gift”, “sample” or “parts”.
- HS classification: provide the correct Harmonised System code at the level required by the process.
- Parties and addresses: supply complete sender, recipient and relevant buyer/seller details.
- Value, currency and quantity: make order and item records consistent with the physical shipment.
- Country of origin and weight: maintain accurate product master data rather than completing it manually for each label.
- Transport references: pass the identifiers required by the carrier or filing party within its cut-off.
Who is responsible for the ENS filing?
Responsibility depends on the transport mode, contractual arrangements and information held by each supply-chain participant. ICS2 supports single and multiple filing. Retailers should obtain a written responsibility map covering who files, who supplies each data element, the deadline, how rejections or referrals are handled, and who corrects source data.
What happens when data are incomplete?
EU customs authorities may reject incomplete declarations or issue a referral requesting more information or screening. That can delay risk assessment and entry processing. The operational response is not to add more generic text; it is to improve the product record and validation before dispatch.
ICS2 readiness check: test a representative order from catalogue to label, compare the electronic record with the parcel and confirm that the filing party received the data before its cut-off.
Connect ICS2 with the wider customs process
ICS2 is a safety and security requirement; it does not replace the customs declaration, VAT treatment or product-specific rules. Retailers can review Asendia’s customs clearance solutions, international ecommerce delivery and IOSS and EU VAT guide as related—but distinct—parts of the cross-border process.
This content is general operational guidance, not customs or legal advice. Requirements depend on the shipment, route, transport mode and parties involved.
Frequently asked questions

An ENS is an Entry Summary Declaration containing the required pre-arrival or pre-loading information about goods, parties and transport.

Which shipments are covered by ICS2 in 2026?
The European Commission states that, from 1 June 2026, consignments entering the EU by any means of transport should have a valid ENS submitted through ICS2 or an eligible combined NCTS Phase 6 process.
What can cause an ICS2 delay or rejection?
Common causes include incomplete party data, vague goods descriptions, incorrect HS codes and inconsistent value, origin, quantity or transport information.
