From March 1st 2023 all Air Cargo transiting or importing to the EU will be subject to ICS 2 Entry requirements (more information can be found here). In effect, Carriers must be provided with House-level information for entry purposes.
Specifically, this operators must ensure EORI Numbers and HS Codes are provided to Air Carriers. Where Air bookings are managed through CW1, this information can be supplied via eAWB automatically.
For purposes of compliance, Great Britain, Switzerland and Norway are treated as being in the Eurozone along with true EU member countries.
