DDP = Seller pre-pays US import duty at checkout.

DDP in plain English

Delivered Duty Paid (DDP) is Incoterms 2020 term published by the International Chamber of Commerce. Under DDP, the seller is responsible for delivering goods to the named address with all import duties, taxes, and customs brokerage fees pre-paid. The buyer signs for the parcel. No further charges, invoices, or customs paperwork for the buyer.

DDU/DAP (Delivered Duty Unpaid / Delivered At Place) — the opposite arrangement. Seller pays carriage only. Buyer is invoiced by the carrier for US import duty + a $5–15 USPS/UPS brokerage handling fee. If the buyer refuses to pay, the parcel is returned to the UK at seller expense or destroyed. Post-de-minimis (Feb 2026 onwards), DDU results in 15–35% refusal rates on UK→US ecommerce.

What gets pre-paid under DDP

For UK→US DDP, the seller pre-pays (in pounds, at checkout):

• Carriage: base UPS Worldwide Economy rate + fuel surcharge (typically ~5%) + Additional Handling surcharge if oversized (2–5kg or dim weight > 30kg).
• US federal import duty: ad valorem percentage from USITC Harmonized Tariff Schedule, applied to declared value. Range: 0% (some books/handicrafts) to 32%+ (apparel, footwear). Minimum floor: 10% (Executive Order 14324 reciprocal tariff) for UK origin.
• Customs brokerage: UPS charges £0 explicitly; cost is bundled into the headline rate. Royal Mail charges implicit brokerage in PDDP price.

What is not covered by DDP for US shipments: state sales tax. US sales tax is a separate obligation determined by your storefront's economic nexus, not by the parcel itself, so it isn't part of the customs entry. Most UK sellers using Shopify or eBay have sales tax collection handled at checkout already.

DDP vs DDU side-by-side: a £40 cotton t-shirt

To make the difference concrete, take a £40 cotton t-shirt — a representative UK Etsy or Shopify order — being shipped from London to a buyer in California in May 2026.

On paper the DDU option looks £4–5 cheaper to the seller. In practice it is far more expensive once you account for refused parcels, return shipping, customer service time, and chargebacks. Industry data on UK→US ecommerce since the de minimis change indicates refusal rates of 15–35% on DDU parcels — every refusal means the seller absorbs the original carriage, the return carriage, weeks of customs storage, and usually a refund to the buyer too.

DDP vs DDU: the critical difference for buyer experience

DDU — Delivered Duty Unpaid — is the opposite arrangement. Under DDU, the seller pays only the carriage; the buyer is invoiced for import duty, taxes, and a brokerage handling fee at the door. Sounds cheaper to you initially, but in practice DDU is now the more expensive choice:

• The buyer is hit with a surprise £4–15 invoice at delivery, plus a USPS or carrier handling fee of $5–15 on top of that.
• Many buyers refuse to pay and the parcel is returned to you at your cost.
• Chargebacks and negative reviews citing "unexpected fees" are common from DDU parcels.
• The parcel sits in a customs warehouse for 1–3 days while the carrier tries to collect payment.

With DDP, all costs are transparent upfront, the buyer's experience is identical to a domestic order, and your refusal rate drops from 15–35% to near zero.

Why DDP is the only sensible choice for UK→US in 2026

DDP existed for decades before 2025, but for low-value ecommerce parcels it was effectively optional: the US $800 de minimis threshold meant most parcels cleared duty-free regardless of Incoterms. That changed in autumn 2025. Executive Order 14324, signed 30 July 2025 and effective 29 August 2025, suspended the duty-free threshold. The simplified $80–$200 flat-fee path for postal parcels expired on 28 February 2026. Today, every UK→US parcel — Royal Mail, UPS, FedEx, DHL — is subject to full ad valorem duty calculated by HS code.

That fundamentally changes the economics. Without de minimis, DDU shipping forces every American buyer to deal with US Customs and pay a brokerage fee at the door. Carrier data and seller-platform reports through Q1 2026 consistently show:

• Refusal rates of 15–35% on DDU parcels from the UK to US consumers.
• USPS brokerage handling fees of $5–$15 per parcel on top of the duty itself.
• A measurable jump in chargebacks and negative reviews citing "unexpected fees" against UK sellers who didn't switch to DDP fast enough.

DDP eliminates all three problems. The duty is paid up front in pounds at a known rate; the parcel clears US customs as a pre-paid import; the buyer's experience is identical to a domestic order.

How a DDP parcel actually clears customs

The mechanics are simpler than they sound. When you book a DDP label through TradeWind, four things happen behind the scenes:

• HS code lookup. You describe your contents (e.g. "cotton t-shirt"); we map that to the correct HTS code (6109.10.00 in this example) using the official USITC tables.
• Duty calculation. The HS rate (16.5% for that t-shirt) plus the 10% reciprocal tariff floor is applied to the declared value. The result is locked in and added to your label price.
• Commercial invoice generation. A PDF commercial invoice is produced automatically with the sender, recipient, contents, HS codes, declared value, and Incoterm marked as DDP. This travels with the parcel.
• Carrier customs entry. UPS submits the formal customs entry to CBP electronically before the parcel reaches the US border. Because the duty is pre-paid, the parcel clears without buyer involvement and goes straight onto the USPS or UPS final-mile network.

The US buyer sees a tracking number that shows "customs cleared" and then "out for delivery". They never receive an invoice, a phone call from the broker, or a doorstep demand for cash.

Frequently asked questions

What does DDP stand for?

DDP stands for "Delivered Duty Paid". It is an Incoterms 2020 trade term where the seller pays carriage, import duty, taxes, and customs brokerage fees up front, so the buyer receives the parcel without any further charges.

What is the difference between DDP and DDU?

Under DDP, the seller pre-pays import duty and customs brokerage fees. Under DDU (now formally DAP under Incoterms 2020), the buyer is invoiced for duty and a brokerage handling fee on delivery. DDU shipments to the US typically incur a $5–$15 USPS or UPS brokerage fee on top of the duty itself.

Who calculates the duty under a DDP service?

The carrier (or its appointed customs broker) calculates the duty based on the declared value, country of origin, and HS code of each line item. With TradeWind, the duty is calculated and locked at the time you book the label using the official USITC Harmonized Tariff Schedule.

Is DDP mandatory for UK to US shipping?

Not legally — but in practice yes. After the end of US de minimis (28 February 2026), every UK→US parcel attracts duty. DDU parcels mean the buyer is hit with a duty bill plus a brokerage fee at the door, leading to high refusal rates. DDP is the only commercially viable option for ecommerce.

How much does DDP shipping from the UK to the US cost?

For a 1–2kg parcel, UPS Worldwide Economy DDP via TradeWind costs roughly £12.8-£15.5 all-in including duty. Royal Mail International PDDP for the same parcel typically costs £19-£24.

What does the seller need to provide?

Sender and recipient address, parcel weight and dimensions, declared customs value, and a content description plus HS code. TradeWind suggests the right HS code from your contents description and generates the commercial invoice automatically.

Does DDP cover US state sales tax?

No. DDP covers federal import duty, reciprocal tariffs, and customs brokerage. US state sales tax is a separate obligation determined by your storefront's economic nexus and is usually collected at checkout by Shopify, eBay, Etsy, etc.

Can I switch from DDU to DDP after dispatching a parcel?

The Incoterm is fixed at the time the label is generated and the customs entry is filed. UPS supports a "Bill Shipper Duty/Tax" account-level setting that can retrospectively bill duty back to the seller, but it is much cleaner to book the label as DDP from the outset.
