DDP stands for Delivered Duty Paid, whereas DDU stands for Delivered Duty Unpaid. They are two international shipping options that determine who is responsible for the payment of duties and taxes.
DDP: The seller is responsible for all costs and risks associated with the transportation of items to the buyer. This includes all customs and taxes. Upon checkout, the customer will pay for the product and shipping, but the seller handles all other costs. Some sellers choose to increase the checkout costs in order to cover the cost of duties and taxes.
DDU: The seller is responsible for delivering the goods, but the buyer is responsible for paying all duties and taxes upon delivery. The buyer also manages documentation and licensing for import clearance. While this option may appear cheaper for your customer at checkout, it can lead to unexpected costs for the buyer. If they don't understand the additional fees, it could keep the customer from being a returning customer in the future or cause them to abandon the shipment altogether.
