On December 17, 2025, the International Trade Administration released a Notice confirming that key elements of the U.S.–Switzerland trade arrangement have now been formalized. A major component is the reduction of the reciprocal tariff rate from 39% to 15%, effective for goods entered for consumption beginning November 14, 2025.  This applies to both Switzerland and Liechtenstein.

Because the change is retroactive, companies that imported Swiss-origin goods since November 14 may be eligible for refunds via post-summary corrections or corrected entries.  

The Notice also clarifies:  

• The 15% cap functions similarly to the EU/Japan deals 
• Certain items listed in Annex I and Annex II may qualify for full exemption
• Civil Aircraft Agreement–eligible goods may also be exempt
• Several classifications continue to rely on existing exemptions due to missing CBP definitions (e.g., “not patented in the United States”)  

Although IMS does not provide tariff classification or customs consulting directly, we work closely with trusted partners who can assist companies in evaluating the impact of these changes.
