A rollover occurs when a booked container is not loaded on the planned vessel and is deferred to a later departure. Common causes include overbooking by the carrier, blank sailings, missed transshipment connections, or customs and documentation holds.
A rollover typically adds one to two weeks of transit. Booking with realistic lead times, respecting cut-offs, and tracking each container milestone are the practical defenses against rollovers.
