@jef I'm definitely not a Trum fan, but unfortunately that's not entirely true. One of the largest product groups that Switzerland exports to the USA are pharmaceutical products, which were previously traded duty-free. Pharmaceutical companies have contracts with the health insurance companies about the price at which a drug is sold. These contracts are still valid, so for the next 1-2 years the customs duties in this area will largely be deducted from the companies' margins.
