A Container Yard (CY) is a designated area where shipping containers are stored, loaded, and unloaded onto trucks, trains, or cargo ships. Container yards play a critical role in the transportation of goods worldwide, providing a temporary home for millions of containers as they make their way across the globe. One main function of the container yard is to store unloaded full containers ready to be picked up and containers marked “ready to be loaded” until the shipping line ships them out. Ocean sailings typically have a CY cut-off date by which the container must be delivered in order to be loaded onto the scheduled sailing.
Container yards are typically located near ports or major transportation hubs to facilitate the transfer of goods between different modes of transportation. Some container yards may be located within the port area, while others may be located nearby.
