Starting Wednesday, August 27, 2025, we will temporarily suspend the acceptance of certain mail items to the United States.
[Affected Mail Items]
Small packets, parcels, and EMS containing merchandise are included in this suspension.
[Reason for Suspension]
This is in response to a U.S. presidential order issued in late July, which eliminates the tax-free exemption, known as de minimis, for inbound international mail.

We apologize for any inconvenience this may cause and appreciate your understanding. We will notify you once mail service resumes.
