Learn what the quote, payment, label, and guarantee prove—and what they do not. language: en published_at: 2026-08-18 last_reviewed: 2026-08-17 carrier_scope: - USPS International Mail — IMM §360 Delivered Duty Paid service - Destination customs and destination postal/carrier actors only where needed to interpret evidence boundaries jurisdiction_scope: - United States outbound international USPS DDP service - Destination-country customs and delivery systems only at the actor/evidence-boundary level - European Union only for routing to the separate July-2026 legal-rule owner --- # USPS Delivered Duty Paid (DDP): What Prepaid Import Duties Mean **USPS Delivered Duty Paid (DDP) is a specific USPS international service for qualifying outbound U.S. shipments.** When the sender uses the USPS DDP path, the sender can prepay an **estimated** amount for import duties, taxes, and fees through the USPS/provider workflow instead of leaving those amounts for the recipient to handle later. That does **not** mean customs has already cleared the package. It also does not mean the USPS quote is the destination customs authority's final assessment. USPS uses a third-party DDP service provider—currently Zonos / iGlobal Exports LLC—and the provider's Landed Cost Guarantee is subject to limitations. The most useful way to read a USPS DDP record is to keep four separate records apart: 1. **USPS DDP offer / eligibility** 2. **Sender quote + prepayment / label** 3. **Destination customs assessment / clearance** 4. **Destination delivery / collection** A record at one stage does not automatically prove the next one. If you already have a concrete repeat charge, a disputed customs assessment, a known customs-declaration error, a customs hold, or a return/refund problem, skip to [What should I do next?](#what-should-i-do-next). Those problems have separate owners. ## What USPS DDP is USPS describes its international DDP service as a way for qualifying U.S. senders to prepay applicable import duties, taxes, and fees at mailing. The service is integrated into certain USPS international shipping flows rather than being a general statement about who pays customs charges in every international sale. The service researched on this page is the **international USPS DDP service in IMM §360**. It applies to qualifying outbound international packages sent from the United States. USPS currently says it does **not** offer this prepaid-duties service for inbound international mail or packages entering the United States. A USPS DDP record is therefore meaningful only when the shipment is actually using this USPS service. A seller saying “DDP,” a marketplace saying “taxes included,” an IOSS/VAT process, or a separate Zonos integration is not enough by itself to prove that the shipment used USPS DDP. ## What “prepaid duties” actually includes USPS uses **“prepaid duties”** as an umbrella phrase for three different components: - **Duties** — customs duties or tariffs assessed under the destination country's import rules. - **Taxes** — import taxes such as VAT/GST or other destination-country taxes where applicable. - **Fees** — separate charges that can include customs-processing fees, foreign postal operator fees, and the DDP service provider's fee. These categories should not be collapsed into one number conceptually, even if the sender sees a combined amount during the USPS transaction. In particular, a **service-provider fee is not a customs duty**. It is part of the service/payment layer. ## What the USPS DDP quote proves — and what it does not USPS's International Mail Manual defines the **Total Import Amount Quote** as an **estimated** amount of applicable import duties, taxes, and fees quoted to the sender. That creates an important evidence ceiling: **USPS DDP quote ≠ destination customs authority's final assessment** A quote can show that the USPS DDP path was offered and that an estimated import amount was produced. A completed DDP transaction or label can show that the sender selected that path and prepaid the quoted amount through the USPS/provider workflow. But the quote, payment, or label does **not** by itself prove that: - the destination customs authority has completed its own assessment; - the final customs amount is identical to the estimate; - customs has released the shipment; - no additional non-payment requirement can arise; - the destination postal operator has accepted the customs result; - delivery or collection is complete. If the actual government customs assessment is the thing you believe is wrong, use [Customs Duty or Import Tax Amount Looks Wrong](/international-shipping/customs-duty-tax-amount-wrong/) instead of treating the USPS quote as the government decision. ## The four records you should not mix up | Record | What it can establish | What it does **not** establish | | --- | --- | --- | | **1. USPS DDP offer / eligibility** | USPS DDP was available in the relevant USPS transaction flow for that shipment at that time | A customs assessment exists; duties were actually prepaid; customs clearance occurred | | **2. Sender quote + prepayment / label** | The sender received a DDP quote and, if completed, selected/prepaid the USPS DDP path | The destination authority accepted the declaration, finalized the assessment, or released the package | | **3. Destination customs assessment / clearance** | The destination authority's customs state, assessment, or release requirement | Final-mile delivery or collection has happened | | **4. Destination delivery / collection** | The local operator's delivery, pickup, or collection state | That every earlier payment or customs record was correct | This prevents several common reasoning errors: **DDP paid ≠ customs cleared** **DDP label ≠ package cannot later be held** **customs released ≠ delivered** **local collection demand ≠ automatically a valid new customs charge** The last distinction matters. A later charge may be a legitimate uncovered amount, a non-customs charge, a data/reconciliation problem, or a mistaken repeat demand. The existence of USPS DDP alone does not classify it. ## Who does what: USPS, the provider, customs, and the destination operator A USPS DDP shipment crosses several systems. The actors are not interchangeable. ### USPS USPS controls the USPS mailing transaction and the USPS DDP service record in supported USPS flows. USPS also publishes the current International Mail Manual and service guidance. A USPS record does not automatically decide: - the destination customs authority's legal assessment; - whether a provider-side guarantee limitation applies; - the destination postal operator's final delivery or collection state. ### USPS DDP service provider USPS uses a third-party service provider for the DDP quote/guarantee layer. Current USPS materials identify **Zonos / iGlobal Exports LLC**. The provider is the actor associated with the Total Import Amount Quote, Landed Cost Guarantee, and provider-side support under its current terms. The provider is **not** the same actor as USPS physical custody, the destination customs authority, or the destination delivery operator. ### Sender The sender chooses or accepts the USPS DDP path, provides the required customs information, accepts the provider terms, and pays the quoted amount when the transaction is completed. The sender remains responsible for supplying complete and accurate customs information. Current USPS/provider materials allow the provider to modify shipping or customs information for accuracy or compliance, but that does not transfer the sender's underlying responsibility for the information supplied. ### Recipient The recipient normally experiences the destination-side result: customs release, a request for information, a local collection demand, pickup, or delivery. The recipient's later experience does not retroactively rewrite what the sender's USPS DDP transaction proved. It is a separate record that may need reconciliation. ### Destination customs authority The destination customs authority controls the destination customs assessment and customs release requirements. A USPS estimate is not a substitute for that authority's assessment. ### Destination postal operator or carrier The destination operator controls its own delivery and collection records. A local operator can also be the place where a mistaken repeat demand becomes visible. ## How the Landed Cost Guarantee works at a high level USPS describes the **Landed Cost Guarantee** as a guarantee provided by the DDP service provider, subject to the provider's terms and limitations. At a high level: - if the actual duties, taxes, and fees during customs clearance are **higher** than the quoted amount, a covered difference can be borne by the provider; - if the higher amount falls outside the guarantee because a limitation applies, the sender/customer can owe the provider the uncovered balance; - if the actual amount is **lower** than the amount prepaid, current USPS/provider materials say the sender does not receive that difference as a refund under the guarantee. This is not an unlimited USPS promise that no additional amount can ever exist. ### Examples of current guarantee limitations Current USPS/provider materials identify limitations that can include problems arising from: - missing or incomplete documentation; - inaccurate or incomplete product/customs information; - inaccurate HS or country-of-origin information; - items that were not included in the quote; - commercially unreasonable declared values; - certain VAT/GST amounts outside the service; - shipments outside the provider's quote-validity conditions. These are examples of the current provider architecture, not a decision about an individual shipment. This page does not determine HS codes, origin, customs value, or whether a specific case is covered. If you already know a declaration, HS code, origin, value, quantity, description, or invoice field is wrong, go to [Customs Declaration, HS Code, Value, or Invoice Mismatch](/international-shipping/customs-declaration-hs-code-value-or-invoice-mismatch/). ## Can the recipient still be charged after USPS DDP was prepaid? USPS's intended DDP flow is designed so that eligible import duties, taxes, and fees are prepaid by the sender. Current USPS guidance also explicitly recognizes that a recipient can be **mistakenly charged again** by the local postal operator. That means two statements can both be true: - the sender has a valid USPS DDP prepayment record; and - a later destination-side payment demand appears. Do not assume the later demand is automatically legitimate. Also do not assume it is automatically a duplicate without checking what the demand actually represents. For a shipment that was sent using USPS DDP and is mistakenly charged again for duties/taxes/fees, USPS currently directs users to the DDP service provider's support route. Use the current [USPS DDP service page](https://www.usps.com/international/prepaid-import-duties.htm) and the provider's [current support page](https://zonos.com/contact-support) to verify the live contact path. Once the problem becomes a **concrete repeat charge, completed duplicate payment, or prepaid-but-not-released state**, the user job changes. Use [Customs Fees Paid but Package Not Released](/package-problems/customs-fees-paid-but-package-not-released/) for the reconciliation problem. ## Does USPS DDP mean customs is cleared? No. A verified USPS DDP quote, payment, or label shows evidence from the **prepayment/service layer**. Customs clearance is a later destination-authority state. A package can still need: - destination customs assessment; - additional documentation; - identity or tax information; - a corrected declaration; - broker/formal-entry action; - another agency review; - resolution of an amount not covered by the DDP guarantee; - destination-operator processing after customs. So a DDP record should never be translated into “customs cleared” unless you also have a customs or destination-system record that actually establishes clearance. If the package is simply held in customs and payment reconciliation is not the primary issue, use [Package Stuck in Customs](/package-problems/package-stuck-in-customs/). ## Which destinations support USPS DDP? **Do not rely on an evergreen country list for this service.** Current USPS first-party destination-availability surfaces are not fully synchronized as of this review. Availability can also depend on the destination, USPS service family, shipment or item conditions, sender/channel, and the live USPS transaction flow. The safe rule is therefore: **Verify DDP availability in the current USPS transaction flow and the applicable current USPS country listing before relying on it.** An eligible USPS service family does not by itself establish DDP availability for the destination or the particular item. So: **eligible USPS service ≠ eligible destination** and: **eligible destination ≠ every item eligible** This page does not resolve conflicting current USPS surfaces by declaring a disputed destination universally eligible or universally ineligible. ## Which USPS services and channels can use DDP? Current USPS first-party sources associate international USPS DDP with these service families: - **Priority Mail Express International** - **Priority Mail International** - **First-Class Package International Service** That does not mean every destination, item, sender, or transaction using one of those services is DDP-eligible. Current USPS materials describe DDP access through: - Post Office retail service counters; - Click-N-Ship; - certain USPS APIs; - Global Shipping Software (GSS). These access paths are operational details and can change. The live USPS transaction remains stronger evidence of actual current availability than a static article. USPS also says the service researched here is for qualifying **outbound packages from the United States** and that it does not currently offer prepaid duties/taxes through this service for inbound international mail or packages. ## USPS DDP is not the same thing as IOSS A mailer's own IOSS/VAT-number process is a separate mechanism. Current USPS FAQ guidance tells mailers who use their own IOSS/VAT number to continue using that process and **not** assume USPS DDP replaces it. This page therefore does not interpret IOSS registration, VAT liability, marketplace deemed-supplier rules, or the detailed EU tax regime. ## USPS DDP is not every Zonos DDP transaction “Zonos” alone does not prove USPS DDP. Current USPS guidance distinguishes USPS DDP through USPS systems from a platform or mailer that may be directly integrated with Zonos and use a separate Zonos DDP solution. The evidence object matters: - **USPS DDP through USPS systems** belongs on this page. - **A separate marketplace/platform Zonos DDP transaction** may belong to that platform's own payment/tax evidence instead. ## USPS DDP is not the same thing as contractual Incoterms® DDP ICC Incoterms® DDP is a contractual trade rule. USPS DDP is a specific postal prepayment service. A USPS DDP label or payment record does not by itself prove that every buyer/seller obligation of Incoterms® DDP governs the sales contract. If the dispute is about the legal obligations in a buyer/seller contract, this USPS service explainer is not the controlling guide. ## The same USPS “DDP” name also appears in a different domestic context USPS also uses “Delivered Duty Paid (DDP)” in a different domestic/customs-territory context under **DMM §507.13**. This page covers only the **international IMM §360 USPS DDP service**. That naming collision is another reason not to activate this guide from the phrase “USPS DDP” alone without checking the actual shipment/service record. ## What about the July 2026 EU €3 customs rule? USPS DDP can be part of the USPS operational path for prepaying estimated duties, taxes, and fees on eligible EU-related shipments. But USPS operational copy is not the legal authority for the general EU customs rule. The detailed legal meaning of the July 2026 EU €3 measure belongs to [EU €3 Customs Duty on Low-Value Parcels](/international-shipping/eu-3-euro-customs-duty-low-value-parcels/). This page does not use the USPS DDP product page to redefine the EU regulation. ## What if the shipment is refused or returned? Do not assume that a refused or returned package automatically causes the prepaid duties, taxes, and fees to be refunded. Current USPS guidance says those import charges are generally ineligible for refund unless the service provider's terms specify otherwise. There is also a separate timing distinction for a USPS DDP shipping label before USPS acceptance. IMM §365 describes pre-acceptance label cancellation/refund separately from provider-side import charges. Once USPS has accepted the package, the rules are different. The correct owner depends on what actually happened: - Need to prepare an international return before tender? Use [International Return Preparation](/international-shipping/international-return-preparation/). - The imported goods were returned and the issue is customs repayment/remission? Use [Customs Duty or Tax Repayment When Returning Imported Goods](/international-shipping/customs-duty-tax-repayment-when-returning-imported-goods/). - The issue is a seller/marketplace refund deadline rather than customs? Protect that route separately; the DDP record does not control the merchant's refund system. ## What should I do next?

You do not need to post private records publicly to understand the case. Keep the records in their original systems and compare them by function: - the USPS service/label record showing the DDP path; - the sender's quote/prepayment record; - any destination customs assessment or release notice; - any later payment request; - the destination operator's collection/delivery record; - any provider case or refund record if a repeat charge occurred. Preserve timestamps, amounts, issuer names, and the exact wording of each record. Do not assume two similarly named amounts came from the same actor. Avoid posting full tracking numbers, customs declarations, invoices with personal data, IOSS/VAT numbers, provider transaction IDs, payment credentials, API credentials, identity documents, or private support correspondence. ## What this page does not do This guide does not: - calculate personalized duties, taxes, or fees; - choose HS/CN/TARIC codes; - determine origin or customs value; - tell you to undervalue or misclassify goods; - interpret your individual provider contract; - guarantee customs clearance; - guarantee that no recipient-side charge can occur; - decide whether a specific later charge is legitimate or duplicate without the underlying records; - contact USPS, Zonos, customs, or the destination carrier for you; - modify customs data, clear or release a shipment, file a refund/dispute, reroute a package, or guarantee delivery. ## Official sources and actions - [United States Postal Service: USPS Delivered Duty Paid (DDP) Service — Prepaid Import Duties](https://www.usps.com/international/prepaid-import-duties.htm) -
