As of April 2025, the United States applies additional tariffs on imports from numerous countries, including Switzerland, as part of the trade policy initiated by the Trump administration. Specifically: 1) Steel and aluminium: 25% supplementary duty on all steel and aluminium products imported into the US, with no exceptions for Switzerland (effective March 2025). 2) Universal 10% baseline tariff: applied from 5 April 2025 to all US imports from any country, as a generalised measure to protect American industry. 3) Switzerland-specific reciprocal tariffs: from 9 April 2025, a 31% rate on Swiss products, calculated based on the bilateral trade surplus and non-tariff barriers identified by the USTR. This is in addition to the 10% baseline tariff. The practical consequences for Swiss exporters are significant: an industrial machine worth CHF 100,000 exported to the US is now subject to US customs duties of up to CHF 41,000 (10% base + 31% reciprocal), compared to previous conventional duties (typically 0-5% for industrial products). The most affected categories include: watches and watch components (a key Swiss export sector to the US), precision machinery and scientific instruments, pharmaceuticals (with some exceptions), and food products (chocolate, cheese). What Swiss exporters can do: verify the HS tariff classification of their products in the American HTS system; check whether sectoral exclusions or temporary exemptions exist; consider restructuring the supply chain (e.g., final assembly in a country with a US free trade agreement); accurately document the origin of goods, as reciprocal tariffs apply based on country of origin, not shipment; contact a specialised forwarder like Franzosini to analyse the impact on each product line and optimise logistics and customs strategy.
