Container rollover (or "rolled cargo") occurs when a container that was booked on a specific vessel is not loaded onto that ship and is instead pushed, or "rolled," to a later sailing.
Container rollover (or "rolled cargo") occurs when a container that was booked on a specific vessel is not loaded onto that ship and is instead pushed, or "rolled," to a later sailing.
Rollovers typically happen when a vessel is fully booked (overbooked) and carriers prioritize certain cargo, when a vessel skips a port call (blank sailing), when documentation or customs issues delay loading, or when a shipment misses the cutoff for cargo receiving. The carrier then rebooks the container on the next available sailing, which can be days or weeks later depending on route frequency.
A rolled container disrupts the entire downstream supply chain, delaying arrival, throwing off inventory and production plans, and potentially triggering additional storage or demurrage costs at the origin port. Shippers with visibility into vessel schedules and carrier booking patterns can anticipate rollover risk and adjust plans proactively rather than being caught off guard.
