Frequently asked questions
What is Passar?
Passar is the Swiss Federal Office for Customs and Border Security (BAZG)'s new digital goods-traffic system. It replaces e-dec for all customs declarations. Passar 1.0 covers export and transit and has been mandatory since 1 January 2026. Passar 2.0 (import) is rolling out from Q2 2026. Passar 3.0 will digitize monitored procedures and the remaining paper forms.
Do I need Passar software, or can I use the BAZG web UI?
BAZG offers a free web UI for low-volume declarants. Companies filing more than a handful of declarations per week typically need either API-connected software, a customs broker, or an autonomous solution like Zolli. The web UI requires a human declarant trained in tariff, origin, and procedure for every single declaration.
How is Zolli different from a customs broker (Zollspediteur)?
A customs broker is a person or firm that files declarations on your behalf — you still wait for their availability and pay per declaration. Zolli is software: as soon as your ERP data is ready, Zolli files the declaration autonomously. Customs brokers can also use Zolli as their declaration engine to scale without hiring more declarants.
How is Zolli different from existing customs software?
Traditional customs software is a user interface that a human declarant operates — it still needs four conditions met at once: data ready, customs expertise, human availability, and manual entry. Zolli removes three of them: only data ready is required. It also runs as a parallel test alongside your current process before any commitment.
What data does Zolli need from my systems?
Whatever your ERP, WMS, OMS, or TMS already produces for an order, shipment, or invoice — Zolli adapts to your data, not the other way around. Connectors exist for direct API, EDI, email, and Excel triggers. Sample data layouts are reviewed in the 15-minute demo.
Is Zolli BAZG-approved?
Zolli files declarations through the official BAZG Passar interfaces, and the documents it produces are the standard outputs (PAEAD, PAIAD, TSAD, PADTS, digital EUR.1) visible on ePortal.admin.ch. Zolli is a member of the BAZG AG SW Passar working group, with direct exchange on Passar implementation.
What does the parallel-run pilot cost?
The parallel run is free. Your existing process keeps filing in production on ePortal.admin.ch, while Zolli files the same declarations in the test environment on ePortal-a.admin.ch. You compare the outputs and decide whether to switch — no commitment.
Which declaration types does Zolli cover today?
As of 16 May 2026: full export (PAEDS to PAEAD), full import (PAIDS to PAIAD with duties and VAT), all four transit scenarios, and digital EUR.1 movement certificates (CH to EU). The homepage news timeline lists the per-milestone rollout history.
What is a PAEDS, PAEAD, PAIDS, PAIAD, PATDS, TSAD, PADTS, GDRN, or MRN?
Each is a Passar message or document type used in the Swiss customs workflow. The Zolli glossary defines every one of them in detail, with the role each plays from declaration submission to the final assessment decision.
Where is Zolli based and who runs it?
Zolli is operated by KikoSpace AG, Burgstrasse 28, 8750 Glarus, Switzerland (UID CHE-113.539.846). It was founded by Dzmitry Kryvashei. Swiss patent application CH000619/2026 was filed at the IGE/IPI in Bern on 1 May 2026.
Does Zolli replace my customs broker?
It can, but it does not have to. Many customers run Zolli as their primary engine and keep a broker for niche edge cases. Customs brokers themselves also use Zolli internally to scale their declaration volume.
What languages does Zolli support?
The product interface, the generated documents, and customer support cover German, French, Italian, and English — Switzerland's national languages plus English for international headquarters.
