What is Passar?

Passar is the new digital goods-traffic system of the Swiss Federal Office for Customs and Border Security (BAZG), replacing e-dec for all Swiss customs declarations. Passar 1.0, covering export and transit, has been mandatory since 1 January 2026. Passar 2.0, covering import, rolls out in stages starting Q2 2026. Passar 3.0 will digitize monitored procedures and remaining paper forms.

What Passar replaces

Before Passar, the BAZG processed customs declarations through e-dec, which used separate applications for export and import. Passar consolidates export, transit and import into a single digital goods-traffic platform.

Declarations are no longer captured through the old forms and standalone applications; instead, they are submitted to the system as structured messages. These messages can be sent through the BAZG web portal or directly from a company's own systems to a programming interface (API). The BAZG provides a web portal (ePortal) and a test environment for connecting. General information on goods traffic is published by the Swiss federal administration at bazg.admin.ch.

Timeline: Passar 1.0, 2.0, 3.0

Passar is being introduced in three stages, each covering a further part of goods traffic:

• Passar 1.0 covers export and transit and has been mandatory since 1 January 2026.
• Passar 2.0 covers import and is being rolled out in stages from Q2 2026.
• Passar 3.0 will digitize monitored procedures and the remaining paper forms, and follows at a later date.

The Swiss federal administration is reachable in general at admin.ch; the BAZG is the authority responsible for goods traffic.

Declaration types on Passar

On Passar, declarations are submitted as different message types depending on the procedure. Each submitted declaration is followed by a corresponding response from the system:

• Export: PAEDS (submitted export declaration) leads to the PAEAD, the export assessment decision (Veranlagungsverfügung Ausfuhr).
• Import: PAIDS (submitted import declaration) leads to the PAIAD, which states duties and VAT.
• Transit: PATDS, accompanied by the TSAD and PADTS documents, and modelled across four scenarios.
• Digital EUR.1: the EUR.1 preferential-origin certificate for goods traffic between Switzerland and the EU.

How Zolli files on Passar

Zolli generates these declarations and submits them autonomously, directly from a company's operational data — from ERP, WMS, OMS and TMS systems. The order and goods data already held in those systems are turned into the appropriate Passar messages and sent to the system.

Before switching over, Zolli offers a free parallel-run pilot: production stays on ePortal.admin.ch while Zolli files the same declarations in parallel in the test environment ePortal-a.admin.ch. This allows the results to be compared before production is switched over. Further answers about the process and connection are available in the frequently asked questions.
