U.S. Revises Tariff Schedule for Swiss Imports Under Pending Trade Deal

The United States has revised tariffs on imports from Switzerland and Liechtenstein, with the changes taking effect retroactively from November 14.

According to a notice issued by the Office of the U.S. Trade Representative, the revised duties take effect from November 14, the date when the changes were first announced. Under the updated tariff schedule, covered goods from the two countries will be charged either the applicable most-favored-nation rate or a 15% duty, depending on which produces the higher levy.

The changes affect a defined set of imports rather than all cross-border trade. Products impacted include certain agricultural items, materials classified as natural resources that are not widely available within the United States, and aviation-related goods such as aircraft and component parts. The revised rules also extend to generic medicines, their active pharmaceutical ingredients, and chemical inputs used in drug manufacturing.

U.S. officials linked the tariff adjustments to an interim trade framework negotiated with Switzerland in November. The administration has set March 31 as the target date to complete and formally adopt the agreement. If talks fail to conclude by that point, the United States said it will reassess whether the tariff structure should remain in place or be modified.

Under the November agreement in principle, the United States agreed to cut tariffs on Swiss imports that had previously reached as high as 39%, lowering them to a maximum of 15%. In exchange, Swiss companies committed to expand investment in the United States, with total planned investment valued at $200 billion by the end of 2028.

Swiss companies have indicated that planned investments will be directed primarily toward U.S. manufacturing and pharmaceutical operations, sectors where Swiss firms already maintain large facilities and workforces. U.S. officials said the tariff structure will remain subject to review until a final agreement is completed.
