eBay international standard delivery is a Delivered Duties Unpaid (DDU) shipping solution—buyers won’t pay duties and tax at checkout on eBay, but may have to pay the carrier for duties and tax on delivery. The Global Shipping Program (GSP) is a Delivery Duties Paid (DDP) shipping program—buyers pay duties and tax during checkout on eBay via GSP. eBay international standard delivery gives you full control of what you want to charge buyers for shipping (Free, Flat, Calculated) from end to end. With GSP, the buyer always sees the GSP shipping charges, and also any costs you set for the domestic shipping leg (Free, Flat, Calculated).
