Delivered Ex Quay or DEQ is a term used commonly in international sales contracts. The seller's obligation ends when he/she places the goods at the disposal of the buyer, on the quay/wharf at the named port of destination, not cleared for import. The buyer clears the goods for import. The costs and risks are transferred to the buyer at the moment when the goods are delivered onto the quay at the named port. Delivered ex quay may be noted as having duty paid or unpaid. If the DEQ is marked as duty paid, the seller is responsible for any costs, such as duty, and risks associated with the delivery. The buyer must pay the costs and duty when the DEQ is marked as "duty unpaid."
