Prepay duties and generate your Japan Post shipping documents with Zonos.
Under new U.S. requirements, postal shipments valued under $2,500 USD (excluding documents and personal gifts valued under $100 USD) must have customs duties prepaid before they can be imported into the United States. Additionally, as of July 1, 2026, many countries in the EU require shipments to be sent with duties prepaid.
Japan Post has partnered with Zonos to provide two compliant shipping solutions. Starting October 1, 2026 (JST), both solutions support shipments to:
United States
Select EU destinations: Denmark, France (including Monaco), Andorra, French overseas departments (Guadeloupe, French Guiana, Martinique), Sweden, Spain, Netherlands, Slovakia, Italy, Finland, Luxembourg, Estonia, and Malta
Both solutions let you prepay duties before your shipment is dispatched.
For individuals and small businesses who ship occasionally
The Zonos app is a free mobile app that handles the entire shipping process — duty calculation, payment, label creation, and customs documentation — all before visiting the post office.
Key features:
AI-powered photo classification to identify items and assign HS codes
Duty calculation and payment in JPY
Japan Post shipping label and customs document generation
Verified Accounts let businesses with a Japan Post deferred-payment (後納) contract create labels with duties prepaid for the U.S. and select EU destinations. Zonos calls the Japan Post Label API on the merchant's behalf, generates the label and Declaration ID, and links them — so every shipment leaves Japan duty-prepaid and customs-compliant.
With a Verified Account:
Every shipment includes a Declaration ID
Zonos creates the Japan Post label using your Later Pay Number
Duties are calculated, invoiced by Zonos, and remitted to the destination's customs authority
Postage continues to be billed by Japan Post to your Later Pay Number
View shipments and labels in the Zonos Dashboard
No subscription fee — only pay duties, postal fees, and the taxes (VAT) on EU shipments that use Zonos' IOSS number
To keep shipping to the U.S. and select EU destinations with Japan Post, choose the solution that fits your business. Both options help your shipments meet the duty prepayment requirements at their destination.
