e-dec → Passar: the migration
e-dec is being replaced by Passar. Passar 1.0 for export and transit has been mandatory since 1 January 2026; Passar 2.0 for import rolls out in stages from Q2 2026, and Passar 3.0 follows later. Declarations move from e-dec's separate applications to structured Passar messages on one platform.
What changes
e-dec was the previous system of the BAZG and used separate applications and forms for export and import. With Passar, declarations are instead submitted as structured messages on a single platform.
The outputs are:
- PAEAD — the export assessment decision.
- PAIAD — the import output stating duties and VAT.
- TSAD and PADTS — for transit.
- the digital EUR.1 certificate of origin.
These are visible on ePortal.admin.ch. General information is published by the BAZG (bazg.admin.ch).

How to prepare for the migration
Connect your ERP data. Zolli files on Passar autonomously and can run in parallel with your current process during the transition, so the results can be compared before you switch over completely.
