IEEPA tariff refund update

2026/06/11

We recognize the importance of the International Emergency Economic Powers Act (IEEPA) tariff refunds to our customers.

 

Due to ongoing legal proceedings and the U.S. government's prospective appeal of the Court of International Trade ruling, the refund process is currently paused. In addition, U.S. Customs and Border Protection (CBP) is implementing its refund process in phases, and processing timelines are determined solely by the government.

 

As a result, refunds may be issued over an extended period, and the timing remains subject to government processing and legal developments. Hamamatsu is unable to influence or expedite this process.

 

We remain committed to these refunds and will provide updates as additional information becomes available. We appreciate your patience and understanding.

President
Hamamatsu Corporation
