> Unlike a general transport delay, a time-slot violation refers specifically to a breach of a reserved time window at a terminal, warehouse, or port: the vehicle arrives too early, too late, or fails to appear at its assigned loading or unloading slot at all.

Unlike a general transport delay, a time-slot violation refers specifically to a breach of a reserved time window at a terminal, warehouse, or port: the vehicle arrives too early, too late, or fails to appear at its assigned loading or unloading slot at all. Terminals and ports levy penalty charges for such breaches to protect dock availability, crane scheduling, and the overall flow of operations. In day-to-day freight forwarding, violations typically result from traffic congestion, knock-on delays from a preceding shipment, or errors in slot booking. Liability for the resulting fees falls on the carrier or the principal depending on the contractual arrangement. Not to be confused with demurrage or detention, which apply to the extended occupation of equipment or berth space – the time-slot violation charge targets the breach of the agreed appointment itself.
