Customer advisory: Transition from IEEPA tariffs to Section 122 tariffs

2026/02/25
  • Hamamatsu Corporation

To Our Valued Customers,

 

The United States Supreme Court has ruled that the tariffs previously imposed under the (IEEPA) are unlawful. In response, the U.S. Government has indicated that these duties will be replaced with tariffs implemented under Section 122 of the Trade Act of 1974.

 

While the Court determined that the IEEPA tariffs were illegal, it did not direct that refunds should be issued. Whether importers will receive refunds for tariffs previously paid remains the subject of future litigation. These proceedings may take several months—or even years—before a final resolution is reached.

 

Hamamatsu is closely monitoring all developments and will continue to act in accordance with official guidance from the U.S. Government as this unprecedented situation evolves. Hamamatsu Corp intends to implement any required changes in tariff value applied to orders shipping on or after March 1, 2026.

 

We genuinely appreciate your continued partnership and patience as we navigate this transition together. 

 

Sincerely,


Earl Hergert
President
Hamamatsu Corporation
