A cross-border shipping model where you, the merchant, pay all duties and taxes so the customer sees one clean price with nothing to pay at the door. The alternative, DDU (Delivered Duty Unpaid), hands the customer surprise charges on arrival and produces high refusal rates - acceptable for low-volume test markets only. Tools like Zonos, Global-e or Passport calculate duty at checkout. One caution: DDP solves the customer's experience of duty and tax, not your obligations. Selling into a market can still require you to register for and remit VAT or GST, and those thresholds are lower than most first-time exporters expect.
Benchmark. DDP converts 20-40% better than making customers pay duties on arrival. Use it for any market you are serious about, and price international markets 10-30% above home so freight, duty and the FX buffer are absorbed into one clean shelf price.
