What is a container rollover and what can I do about it?
Quick answerFour causes: overbooking, blank sailings/omissions, transshipment congestion, and documentation failures (VGM, customs, DG approval). If rolled: get written confirmation, demand priority on the next vessel, request waiver of detention/demurrage caused by the roll, and keep records for claims.
Why it happens
Carriers book more cargo than the vessel can load to protect utilisation.
Blank sailings remove capacity with little notice.
Transshipment cargo loses priority to direct bookings at hubs.
Mitigation
Book earlier in peak season and prefer direct services.
Keep documentation ready before cut-off so you are not the reason for a roll.
Ask the forwarder for a space-protection commitment on key lanes.
| Cause | Frequency | Preventable |
|---|---|---|
| Overbooking | most common | partly (book early) |
| Blank sailing | common | no (monitor) |
| Hub congestion | transshipment | partly (choose direct) |
| Documentation | avoidable | yes |
Frequently asked questions
