Knock-On Delay
A knock-on delay refers to a chain reaction of scheduling disruptions that starts with a delay at one point in the logistics process and spreads to subsequent stages. For example, a late vessel arrival can delay unloading, which then affects customs clearance, trucking schedules, and final delivery. Even a small disruption can ripple across the supply chain. This is why knock-on delays are often more costly than the original delay itself.
In logistics, processes are closely linked and time-dependent. When one activity runs behind schedule, the next activity may miss its allocated time slot or resources. This can lead to congestion, missed cut-off times, additional storage charges, or rescheduled transport. Knock-on delays are common during peak seasons, weather disruptions, or operational bottlenecks. Managing them requires quick coordination and clear communication.
Understanding knock-on delays helps logistics teams plan buffers and contingency options. Real-time tracking, proactive updates, and flexible scheduling reduce the impact when disruptions occur. By addressing the root cause early, businesses can prevent delays from cascading through the rest of the shipment journey.
