The seller delivers the goods to a named place of destination but is not responsible for unloading. His responsibilities include packing, export clearance, carriage expenses and any terminal costs up to the agreed destination port.
DAP means the buyer is responsible for all costs, duties and taxes associated with unloading the goods. He is also responsible for clearing customs to import the products into the named country of destination.
The risk is transferred to the buyer at the final designated place of destination.
