Among the reciprocal tariff levels Trump announced:
China: 34%
European Union: 20%
South Korea: 25%
India: 26%
Vietnam: 46%
Taiwan: 32%
Japan: 24%
Thailand: 36%
Switzerland: 31%
Indonesia: 32%
Malaysia: 24%
Cambodia: 49%
United Kingdom: 10%
Rest of the world: 10%
I checked and this does seem to fit for Switzerland.
Trade deficit of US to Switzerland: 38.5 B
Exports from Switzerland to US: 63.4 B
Ratio of the two: 61%
Half of that as “reciprocal” tariff: 31%
