In a notice published on 27 July 2026—within the last 24 hours—the Federal Office for Customs and Border Security (BAZG) announced that its online tariff database ‘Tares’ will be refreshed on 1 August 2026. Tares is the legally binding reference for all customs duty rates, commodity codes and import restrictions applicable at Swiss borders. The forthcoming update reflects annual rate adjustments, the integration of revised Harmonised System (HS) codes, and minor textual clarifications linked to free-trade agreements. Importers and customs brokers are advised to download the new data files or interface tables in advance to ensure their declaration software remains compliant from 00:00 on 1 August. For global mobility teams the change is more than an administrative footnote. Personal effects shipments, sample consignments or “trainee kits” that arrive in early August will be assessed against the new schedule. An incorrect HS code or outdated duty rate can lead to delays, retroactive assessments and unnecessary costs for the sponsoring employer or relocating employee. BAZG recommends that companies using third-party logistics providers verify that partners have loaded the August tariff. The agency’s customs help-desk will operate extended hours on 1 and 2 August to handle classification queries. Because the update coincides with Switzerland’s National Day—a period of peak leisure travel and gift imports—mobility advisers should circulate an internal bulletin reminding travellers to keep purchase receipts handy and declare goods accurately. Leveraging the ‘QuickZoll’ mobile app, which automatically pulls data from Tares, can streamline the process for both occasional business travellers and frequent cross-border commuters.
