Japan Post will stop accepting packages bound for the United States with a declared value of more than $100 or which contain commercial items.

The pause, which begins Wednesday, follows an executive order signed by U.S. President Donald Trump on July 30 and effective Aug. 29, which suspends duty-free ¡°de minimis¡± treatment for packages with a declared value of less than $800.

Parcels from China lost de minimis treatment in May. Now, parcels from all countries will be tariffed if their value is greater than $100.

Japan joins a growing list of countries that have adjusted their policies on parcel shipments to the United States following the executive order. Australia, Belgium, France, Germany, Italy, New Zealand, Spain and Sweden have all responded by limiting or stopping service.

Deutsche Post¡¯s DHL will ¡°no longer be able to accept and transport¡± U.S.-bound items containing goods from business customers.

Letters, printed documents and personal gifts valued at $100 or less will still be accepted for delivery to the United States, Japan post said.

For more expensive items and for commercial deliveries, customers can use Japan Post¡¯s U-Global Express, also known as UGX, a delivery service that was started in 2014 and charges rates comparable to EMS.

A 2-kilogram package sent to New York by Japan Post would cost ?10,350 using UGX, ?7,900 by EMS and ?4,820 using Japan Post¡¯s small-packet service, according to the Japan Post website. Only UGX will be available for the affected items from Wednesday.

Specific procedures to be implemented by postal service providers remain unclear, making practical operations extremely difficult, Japan Post said in an announcement on Monday.

¡°Key questions remain unresolved, particularly regarding how and by whom customs duties will be collected in the future, what additional data will be required, and how the data transmission to the U.S. Customs and Border Protection will be carried out,¡± DHL said in a statement last week.

Ryosei Akazawa, Japan¡¯s minister in charge of tariff negotiations with the U.S., said the overall effect is expected to be limited as the majority of noncommercial items sent to the U.S. from Japan are valued at under $100, and alternative shipping options are still available for the affected items.

¡°The government will ask Japan Post to provide careful explanations of the alternatives available, so that users are not left confused,¡± he said at a news conference Tuesday.
