Will my buyer incur additional charges because the item is shipping internationally?
If applicable. When international buyers view your listings, they’ll see shipping charges and estimated import charges.At checkout, the buyer will see final charges based on the destination country, including the item price, shipping charges, and import charges (if applicable).
Shipping charges include any US shipping charges you specify, as well as applicable international shipping, handling, and any other fees from the carrier.Who pays duties and taxes?
The buyer is responsible for settling all charges or fees in order for customs to release the shipment and have it delivered to the buyer.What do Duties Delivered Paid (DDP) and Duties Delivered Unpaid (DDU) mean? And what’s the difference between them?
The customs clearance service is an important part of international shipping and is meant to facilitate the import of goods to your buyer’s country. With a Duties Delivered Paid (DDP) shipment, the buyer pays import charges at checkout. With a Duties Delivered Unpaid (DDU) shipment, the buyer pays any applicable import charges prior to delivery. DDU shipments may also result in the buyer being assessed additional delivery fees by the carrier.What options does provide to buyers to pay duties?
International Shipping offers both Duties Delivered Unpaid (DDU) and Duties Delivered Paid (DDP) options to buyers. Currently, the option to be used is predefined for every transaction based on the item price, item weight, and buyer shipping country. Later this year, International Shipping will enable buyers to choose how they prefer to have their shipment cleared through customs — using DDP or DDU.
