Thank you for visiting our store. Although we are excited to send you the kit you purchase, we may have some difficulty shipping to USA for certain expensive items. ==Announcement by Japan Post== (August 25,2025) On July 30, 2025, the U.S. government issued an executive order titled “Termination of De Minimis Treatment for All Countries” regarding mail to the United States. Under this executive order, starting August 29, 2025, mail containing goods imported for personal use (taxable mail) will no longer be eligible for duty-free treatment, and tariffs will be imposed. On August 15, 2025, U.S. Customs and Border Protection (CBP) announced new guidelines regarding the elimination of de minimis rules, which require that transport operators pay customs deposits to CBP and prepare customs declarations. The procedures that transport operators and postal operators in each country must follow to comply with these guidelines are not clear, however, making implementation difficult.
