Swiss businesses are operating under a cloud of legal and policy uncertainty regarding US trade barriers, as the federal government continues to collect tariffs despite a Supreme Court ruling declaring them unlawful.

The disconnect between judicial precedent and executive action has created a volatile environment for exporters, who must plan for potential retroactive adjustments or prolonged litigation.

The situation stems from a November agreement between Switzerland and the United States that established a temporary tariff truce.

While this deal provided immediate relief, negotiations for a definitive, long-term trade agreement remain ongoing.

The lack of a finalized treaty means that the underlying legal framework for US tariffs remains contested, with the Supreme Court's February decision casting doubt on the administration's authority to impose these measures.

Despite the court's finding that the tariffs were illegal, the US government has announced it will continue collecting duties.
