A more thorough explanation:

Definition: Delivered ex quay is a term used in business contracts that outlines the responsibilities of the buyer and seller regarding the delivery, payment, and risk of loss of goods. The seller is responsible for clearing the goods for export, paying for transportation to the port specified by the buyer, and placing the goods next to the ship in the destination port. The delivery is considered complete when the goods are unloaded at the destination port, and the risk of loss passes to the buyer. This term is only used for goods transported by sea or inland waterway.

Example: A company in China agrees to sell 1000 units of a product to a company in the United States. The contract specifies that the delivery will be "delivered ex quay" to the port of Los Angeles. The Chinese company is responsible for clearing the goods for export, paying for transportation to the port of Los Angeles, and placing the goods next to the ship. Once the goods are unloaded at the port of Los Angeles, the delivery is considered complete, and the risk of loss passes to the US company.

Explanation: In this example, the term "delivered ex quay" outlines the responsibilities of the Chinese company as the seller and the US company as the buyer. The Chinese company is responsible for all costs associated with getting the goods to the port of Los Angeles and placing them next to the ship. Once the goods are unloaded at the port, the delivery is considered complete, and the US company assumes the risk of loss. This term is only used for goods transported by sea or inland waterway, as it specifically refers to the placement of goods next to a ship in a port.
