Selling DDU is why your international customers refuse delivery.
Delivered Duty Unpaid (DDU) often leaves customers with unexpected fees when their order arrives. Many refuse delivery or abandon future purchases. With Delivered Duty Paid (DDP), taxes and duties are shown and paid at checkout, so customers know exactly what they'll pay.
How leading brands simplified global checkout

Brands like Anastasia Beverly Hills, Bloom Nutrition, and Ombraz have switched to landed cost checkout with DDP on every order.
Their customers see the full price upfront, with no surprise fees at delivery. The result is fewer refused deliveries, higher conversion rates, and fewer customer support tickets. Customers pay once, and brands avoid unexpected returns.

Frequently asked questions
What's the difference between landed cost and DDP?
Landed cost is the total final price a customer pays — product, shipping, taxes, and duties combined. DDP, or Delivered Duty Paid, is the shipping term that means the customer pays the full landed cost upfront, with nothing extra collected at the border. We calculate landed cost at checkout and ship DDP on every order.
How do you calculate accurate duties for every product?
Our proprietary tax engine calculates duties using your product's HS code, country of origin, destination country, basket value, and applicable customs regulations. It also factors in clearance methods, tariffs, and local import rules to ensure every duty calculation is accurate and guaranteed.
What happens if duties are higher at the border than calculated?
OpenBorder provides guaranteed duty calculations. If the actual duties charged at the border are higher than the amount calculated at checkout, we cover the difference, so neither you nor your customer pays more than expected.
Do I need to register for VAT or sales tax in every market?
No. Based on your setup, OpenBorder can act as the Merchant of Record or Seller of Record to collect and remit taxes on your behalf through our global registrations and entities. That means you don't need to register, file, or remit VAT or sales tax in every market yourself.
What about countries with low de minimis thresholds?
Some markets — like the UK and EU — have low or zero de minimis thresholds, which means duties and taxes apply to almost every order. Other markets have higher thresholds. Our calculations account for the threshold rules in every market we serve, so the landed cost shown at checkout is always accurate.
