UPU Delivered Duty Paid solution

The UPU Delivered Duty Paid (DDP) solution enables Posts to collect duties and taxes at origin, improving customs clearance efficiency and providing full landed cost transparency to customers.

The solution is available through CDS and APIs and supports integration with certified third-party providers.

As of 18 February 2026, the following third-party providers are integrated with the UPU DDP solution.

New release: CDS 2025


New release: CDS 2025 has been released on December 2025.

This version provides generic API interfaces for integration with 3rd party providers. Some of these providers (in the USA: Qualified Parties by US Customs) are completing their integration with the UPU DDP and currently applying for UPU-TechCert certification.

The list of UPU-TechCert certified providers will be published and updated on this page when they are granted the certification.
Users of the UPU DDP will then be able to choose (configuration parameter in the CDS) the provider of their choice. UPU DDP will work seamlessly with any of the certified providers.

This version provides also two new configuration parameters to support additional fees applied by Posts on top of landed (flat fee and percentage fee)

UPU Delivered Duty Paid (DDP) is a product:

  • • for the shipping of goods
  • • that are subject to taxes and duties at destination
  • • and for which the taxes and duties are collected at origin (before shipment).

The UPU DDP provides 3 integrated options for the payment:

  1. Pay at Post (Post of origin collects the taxes and duties for the country of destination).
    This is the typical model for Over The Counter (OTC) transactions with retail postal customers.

  2. Pay directly the 3rd party provider.
    Here again this targets the retail customers and it is particularly adapted when the post of origin cannot collect taxes and duties for a destination country. In that case a payment solution is directly provided by the 3rd party (for example: mobile App or payment link to a trusted payment platform) and the CDS is informed of the payment status prior to collecting the mail item for shipment.

  3. Pay on invoice the 3rd party provider.
    Similar to the previous option, however the payment on invoices targets the business customers (typically: eCommerce platforms). Those type of trusted accounts can be registered at the 3rd party provider and be invoiced at regular intervals for their shipments. Likewise, the CDS software is informed of the payment status prior to collecting the prepared shipments.

General DDP considerations:

DDP (an international commercial term, or Incoterm) is particularly suited to e‑commerce shipments by Posts. It is designed to accelerate customs clearance at destination and, for a customer buying online, DDP means that all relevant information (full shipping costs including postal delivery and taxes and duties) is available at the time of purchase.

However, DDP entails additional tasks and responsibilities for the origin Post. Specifically, the origin Post must inform the shipper of the applicable taxes and duties, collect the corresponding amounts and transfer these amounts to the customs authority at destination.

To help designated operators adopt this model quickly, the UPU’s Postal Technology Centre (PTC) is rolling out a DDP solution that leverages existing UPU technologies and services:

  • • For data flows, the Customs Declaration System (CDS) and POST*Net are at the core of the solution. UPU DDP APIs are also available for non-CDS users, through the PTC API Gateway;

  • • For financial flows and international settlement, it is envisaged that UPU*Clearing will be used. This part of the solution will follow at a later stage, pending approval by the UPU*Clearing User Group.

The various sections on this page provide updates on the different components of the UPU DDP solution.

Please refer to the DDP Implementation Guide for guidance and to prepare for roll-out of the solution and IT integration.

Regulatory changes for US-bound flows


Since 29 August 2025, the duty-free de-minimis threshold for mail items containing goods entering the United States of America has been suspended. Only goods with a value under 100 USD and declared as gifts remain exempt.

These changes have accelerated the agenda for the UPU DDP solution. The information on this page, and in the DDP Implementation Guide available below, covers both the global UPU DDP solution and, when applicable, the specific case of US-bound flows.

US regulations require that a US qualified party (QP) be used to file declarations with the US Customs and Border Protection agency (CBP) and for the financial settlement of the applicable taxes and duties with the CBP.

Key features of UPU DDP

Available as a turnkey solution in CDS software

All versions (CDS.post, Cloud, local instances) and via all interfaces (CDS UI, Kiosk, EAD Customs Declarations (mobile application) and CDS.API)

Available as APIs for non-CDS users

The solution is accessible to any Post via APIs.

Settlement and EAD features

Scalability and security for international settlement flows

To follow at a later stage through UPU*Clearing

EAD compliance requirements embedded in the solution:
  • Harmonized System (HS) codes: look-up or verification checks
  • Prohibitions and restrictions checks
  • Denied parties checks
EAD quality checks embedded in the solution:
  • UPU SAVE

Label/S10 and licence


Supports two scenarios for label/S10 creation:
  • S10 is unknown at the time when landed cost calculations (LCC) are conducted. UPU DDP uses a declaration ID – a temporary ID for tracking the draft declaration and associated landed costs until the mail item label/S10 is created
     
  • S10 is known at the time of LCC.  This is typically the case when the shipper is provided with S10 ranges by the origin Post. In this case, UPU DDP still uses a declaration ID as above, but the associated S10–declaration ID is created immediately after LCC.

Available as an option to your CDS licence

 

For US-bound flows

UPU DDP can be powered by any QP


Each origin Post can select its QP


An origin Post can decide to use more than one QP 
(from CDS 2025 SP1 onwards)

This is made possible with coding in ITMATT to specify which QP is used for the mail item.


Data copied from POST*Net to the QP
Only the data required for the CBP filing is uploaded to the QP; no personally identifiable information is copied. For the filing, the item ID (S10), declared value and country of origin, as well as the transport information, are provided.
Copies are activated upon formal authorization by the Post.


UPU DDP – Guided Flow in CDS Kiosk and CDS Web interfaces

The screenshots below show the CDS Kiosk and CDS Web interfaces, updated to support Delivered Duty Paid (DDP).
They include automatic duty and tax calculation and display the full landed cost to users.


1. Customs data entry (CDS Kiosk interface)

The operator enters content details (description, weight, value, HS code). This data is used to automatically calculate applicable duties and taxes.


2. Landed cost breakdown

Based on the declared information, the system calculates duties, taxes, and fees.


3. Final cost summary and settlement details

The system displays the final landed cost along with settlement identifiers. The customs declaration can then be converted into an ITMATT message.
