What is ICS2?
ICS2, the Import Control System 2, is the EU’s advance cargo information system for safety and security. Before goods from outside the EU arrive, or in some cases before they are even loaded abroad, carriers and other parties must file data about the shipment in an entry summary declaration (ENS). Customs uses it to assess risk and can stop high-risk cargo from being loaded or ask for checks on arrival.
ICS2 covers the EU plus Switzerland and Norway. It was rolled out in three releases: postal and express air consignments from March 2021, all air cargo from March 2023, and sea, inland waterway, road and rail from June 2024, with transition periods ending in 2025.
Core principle: ICS2 is a security filing, not a customs clearance. It doesn’t calculate duty, but bad data in it can stop goods from moving.
Who files the ENS
Carriers
Shipping lines, airlines, road hauliers and rail operators file the ENS for the transport they perform.
Watch out for: They will refuse cargo if the shipper’s data isn’t good enough.
Freight forwarders and postal operators
Where a forwarder issues its own house bill of lading or air waybill, it may file the house-level data itself, including the real buyer and seller.
Why it matters: This multiple filing is new in ICS2 and means forwarders need accurate data from you and your supplier.
Filing deadlines
| Mode | When the ENS is due |
|---|---|
| Air | Minimum pre-loading data before loading at the last foreign airport; full ENS before arrival |
| Deep-sea containers | At least 24 hours before loading at the foreign port |
| Road | At least one hour before arrival in the EU |
| Rail | At least two hours before arrival in the EU |
Data that causes problems
ICS2 checks the quality of the data, not just whether it is there. Shipments are held or refused when:
- Goods descriptions are vague, such as “gifts”, “parts”, “accessories” or “consolidated goods”
- The six-digit HS code is missing or doesn’t match the description
- The buyer and seller are missing, or only the forwarder’s details are given
- Names and addresses are incomplete
ICS2 vs US ISF
Both are advance security filings. In the US, the importer is responsible for the Importer Security Filing and the carrier for AMS. In the EU, the carrier and, at house level, the forwarder file the ENS. Importers don’t file ICS2 themselves, but their supplier’s and forwarder’s data must be accurate.
What it means for brands importing stock
- Make sure your supplier’s commercial invoice has specific descriptions and six-digit HS codes for every line.
- Give your forwarder full buyer and consignee details, including your EU EORI number.
- Expect holds if data is wrong, and allow time for them in your inbound planning.
Example: A brand’s supplier in Shenzhen books a container to Rotterdam with the description “household goods”. The forwarder’s ICS2 filing is flagged, and the shipping line won’t load the container until the description is changed to “stainless steel cooking pots, HS 7323.93” and the buyer’s details are added. The container misses its vessel and arrives a week late.
Frequently asked questions
What does ICS2 stand for?
Import Control System 2, the EU’s system for advance safety and security data on goods arriving from outside the EU.
What is an ENS?
An entry summary declaration: the safety and security data about a shipment that must be filed in ICS2 before the goods arrive.
Do importers file ICS2?
Usually not. Carriers and, at house level, forwarders and postal operators file it, but they depend on accurate data from the shipper and buyer.
Does ICS2 replace the customs declaration?
No. ICS2 is a security filing. Goods still need an import declaration, and duty and import VAT are paid then.
Does ICS2 apply to Switzerland and Norway?
Yes. Switzerland and Norway take part in ICS2 alongside the EU.
