A CY (Container Yard) cutoff refers to the deadline set by carriers for shippers to gate-in or check-in their loaded containers at the designated container yard. It is the specified date and time by which the containers must be physically present at the container yard to ensure they can be loaded onto the scheduled sailing vessel. Its date is typically determined by the carrier and is generally set a few days before the scheduled departure. Adhering to the CY cutoff is crucial for shippers to ensure their containers are included in the intended sailing and avoid delays or missed shipments. Meeting the CY cutoff allows for the efficient coordination of container handling and vessel loading operations.
