Because large distribution centers are so efficient, they

High-throughput DCs rely on dock scheduling and appointment adherence to balance labor, doors, equipment, and carrier arrivals. The CLT dispatch/tracking content highlights the need to coordinate inbound and outbound flows, sequence trailer movements, and manage yard/door assignments to maintain productivity and safety. Strict schedules minimize queueing, overtime, and detention risk while keeping pick/pack/ship synchronized. Accepting unscheduled arrivals broadly would disrupt resource plans and can cascade into missed carrier cutoffs. While some sites may provide limited unscheduled windows, the standard is structured dock appointments and adherence. Detention policies are governed by contracts; efficiency does not imply waiving charges.
