Most of the buyers want convenience, stress free and one-stop coordination for their goods to be delivered in their own warehouse in the importing country. Some would prefer one-stop quotation for the logistics service. Therefore the buyers will ask their suppliers/sellers to handle this kind of shipment which falls under DDU or DDP transactions. We have many shipments under these terms and we can proudly say that we are exemplary. Though, these terms are old international trade where the seller is responsible for the safe delivery of the goods to destination. These terms were in under Incoterms 2010 and are now converted to more comprehensive & specific terms in Incoterms 2020. But these terms are still use in these days as part of the traditional shipping terms in actual. 

Different between DDU & DDP explained: 

Delivered Duty Unpaid (DDU) means that the seller is responsible for the safe delivery of goods to a named destination, paying all transportation expenses and assuming all risks during transport. Once the goods arrive at the agreed-upon location, the buyer becomes responsible for paying import duties, as well as further transport costs. However, Delivered Duty Paid (DDP) indicates that the seller must cover duties, import clearance, and any taxes.
