What “rolled” means
Your container misses the vessel it was booked on and is moved to a later sailing. Nothing is lost, but everything moves — the ETA breaks, the buyer’s plans break, and any payment tied to arrival moves with it.
The deadlines that matter
- Documentation / SI cut-off. Shipping instructions must reach the line by this time or the Bill of Lading cannot be prepared correctly.
- VGM cut-off. The verified gross mass must be submitted. Without it the container cannot legally be loaded.
- Gate-in / port cut-off. The physical container must be inside the terminal. Miss this and the box does not travel, whatever the paperwork says.
- Customs clearance. The shipping bill must be filed and Let Export Order obtained before the container can move to the port.
A useful rule of thumb for sea freight from India: work back roughly ten days from departure for the container to be handed over comfortably. Later than that and every delay downstream — a customs query, a transport shortage, a holiday — starts eating into the margin.
Where the days actually go
Exporters usually plan for the port cut-off and forget what sits in front of it. Customs clearance can take days if a query is raised. Rail movement from an inland container depot adds transit time. A public holiday removes a working day from the chain without warning.
How to protect a sailing
- Work backwards from the cut-off, not forwards from stuffing.
- Watch rail-out as the checkpoint — if the container has not moved and the cut-off is close, that is the moment to escalate.
- Know your festival and holiday calendar. Diwali week alone can absorb the buffer you were relying on.
- Escalate to your CHA while there is still time to act. After the cut-off, the only option is the next vessel.
