Cut-off time in shipping: meaning
A cut-off is a deadline the carrier or terminal sets before a ship departs. Miss it and the container can be rolled to a later sailing. The main ones are the cargo (CY) cut-off, the documentation (SI) cut-off and the VGM cut-off.
At a glance
Why cut-offs exist
The terminal plans how the ship is loaded and the carrier must send cargo data to customs before loading, so both need the containers, the bill of lading data and the weights in advance. Each cut-off is set for the sailing and the terminal, and the booking confirmation states them, usually as a date and time in local time.
VGM and advance cargo data
Under SOLAS, a packed container must not be loaded without a verified gross mass, so the VGM cut-off is strict. Some destinations also require cargo data before loading at the port of origin, for example the US 24-hour rule for the carrier's cargo declaration and, for ocean shipments to the United States, the importer's ISF at least 24 hours before loading, which can bring the SI cut-off forward.
If you miss a cut-off
The container may be rolled to the next sailing, with possible extra storage or amendment charges, or the bill of lading may be issued late. If a deadline looks tight, ask the carrier or forwarder early whether a late gate-in or a late SI is possible; it is at their discretion and may cost extra.

Common questions
What is the CY cut-off?
The deadline for delivering the full container to the container yard (terminal) so it can be loaded on the booked vessel.
What is the SI cut-off?
The deadline for sending the shipping instruction with the data for the bill of lading. After it, changes may cost an amendment fee or delay the B/L.
Is the VGM cut-off the same as the cargo cut-off?
Not always. Each carrier and terminal sets its own VGM deadline, which can be before or at the cargo cut-off; check the booking confirmation.
