What is customs clearance cutoff, document cutoff, and port cutoff?

What is "Closing Time", "SI Cut-off", and "CY Closing"?

In the maritime shipping process, "Closing Time," "SI Cut-off," and "CY Closing" are three critical time points that directly affect whether cargo can be shipped smoothly. These three concepts are explained in detail below:

1. Closing Time

Definition: Closing Time, also known as the cargo release deadline, is the cutoff date and time for customs declaration and clearance of goods. This means all export cargo must complete all procedures for customs declaration and obtain clearance permits before this deadline. In short, it is the final deadline for customs clearance. After this time, if the cargo has not completed the customs process, it may not be loaded onto the scheduled vessel on time.

Importance: Ensures that cargo can clear customs on time and be smoothly delivered to the terminal for loading, avoiding additional costs or missed sailing schedules due to delays.

2. SI Cut-off

Definition: SI Cut-off refers to the final time for the shipping line to accept changes to the bill of lading (B/L) information. After this time, if modifications to the B/L content are needed, such as shipper, consignee, or cargo description details, the shipping line will typically charge an additional fee (e.g., late amendment fee or change fee). Some shipping lines implement a one-time submission policy, where any subsequent corrections after B/L data is submitted will incur charges.

Importance: Ensures the accuracy of B/L information, avoiding trade disputes or disruptions in the consignment process caused by incorrect data.

3. CY Closing/CY Cutoff

Definition: CY Closing refers to the final time the terminal stops accepting cargo containers. After this deadline, even if the cargo has completed customs clearance, it may no longer enter the terminal area for loading. This time limit is set by the terminal to ensure orderly operations, and to ensure cargo is loaded and vessels depart as scheduled.

Importance: Ensures terminal operational efficiency, avoids terminal congestion from late container acceptance, and guarantees that vessels depart on time.
