From January 1, 2021, the international postal service requires the transmission of Electronic Advance Data (EAD) for customs clearance. We support this feature, so rest assured!
For the United States, the "STOP Act", which is a law in the United States, notifies that mail items for which customs electronic data has not been sent will be returned to you. For other countries, it has been announced that there will be a risk of delay and return. For more details, please check the Japan Post page.
[ Postal services requiring EAD ]
EMS (goods), International parcels, Small packets, International ePacket / ePacket Light
As for handwritten labels, there will also be a risk of delay in customs clearance or return, and in principle, JP Post will not accept handwritten labels addressed to the United States.
Since Ship&co is functionally integrated with JP Post's "International My Page System", all types that are subject to customs clearance EAD obligations are supported when you create shipping labels with Ship&co. Please be assured that Ship&co got you covered for this!
【IOSS Number for EU shipments】
Japan Post system doesn’t officially support yet IOSS number electronically. Therefore, adding the IOSS number in the Address_field doesn’t guarantee that it will be used for custom clearance. The same issue occurs in the JapanPost MyPage. Please be noted that currently, carriers that support IOSS number are only UPS, DHL and FedEx.
