The export of goods to countries that are not part of the European Union (e.g. Switzerland) requires customs clearance. GLS offers for this purpose simple customs data entry via the Customs Portal and the Customs Interface.


Customs data collection made easy

Customs-related data must preferably be available to GLS in electronic form (via the Customs Portal or the Customs Interface) during pickup, but at the latest when the parcel is processed in the dispatch depot. If the data is delayed in reaching us, lead time delays in the export process may occur.

Besides the pure customs data also export related documents, especially commercial invoice and export declaration, can be provided electronically via the Customs Portal or the Customs Interface.


GLS Customs Portal
Required customs data for parcel shipments to non-EU countries must be entered via the Customs Portal or can be uploaded as documents (possible formats: CSV, XML, XLSX), to ensure a smooth outbound and inbound customs clearance.

The Customs Portal can be accessed here: gls-customs-portal.next.aeb.com/portal
