DES DeliveredEx Ship

The seller's obligation ends when they have delivered the goods to the disposal of the buyer on board the ship, cleared for export, but not cleared for import but delivered the named port of destination before discharging.

The buyer is responsible for customs clearance at the country of import and all charges for discharging off the ship (Destination Unloading, Terminal Handling and/or Container Service Charges-CSC)

If the seller is also to be responsible for discharging the goods off the ship, then the DEQ term should be used.
