On December 31, 2026, Switzerland's customs program DaziT will officially be concluded. DaziT was launched in 2018 to replace legacy systems and further digitalize customs procedures.
For readers outside Switzerland, a brief explanation: Switzerland is not a member of the European Union and has its own customs border. Goods must therefore be declared for import and export. The Federal Customs Administration and Border Security Office, known as BAZG, is responsible.
With the end of DaziT, this modernization is not yet complete. An important component is the new goods traffic system Passar. It gradually replaces existing programs for transit, export, and import.
For transit and export, the transition has already been largely completed. For import, it is still ongoing. The legacy e-dec Import system can be used until September 30, 2027, according to current planning. After that, imports should only be declared via Passar.
This affects not only customs brokers. Importers, exporters, transport companies, courier services, software providers, and foreign suppliers must also adapt their processes. Anyone delivering goods to Switzerland should know what information the recipient or their customs representative requires.
Additionally, the previous ZAZ account number will be replaced by a Business Partner ID, or GP-ID for short. Companies must register for this in the federal ePortal. Automatic transfer of existing accounts is not planned. Therefore, it should be clarified in good time who will handle the registration and receipt of customs documents.
Border processing will also become more automated. In Passar, a prepared goods declaration only becomes legally binding through so-called activation. Ideally, this occurs digitally at the border crossing. To achieve this, the goods declaration, transport data, and vehicle must be correctly linked together.
DaziT as a program will soon be concluded. However, until the new systems run smoothly across the board and the legacy applications disappear, there is still considerable work to be done.
