Cross-docking is a logistics operation, of unloading materials from an incoming semi-trailer or a rail car, and loading the materials into other trailers/rail cars with no storage time between. This can happen to change transport types, or to sort, or combine material intended for different locations.
Often done directly, with minimal, or no warehousing. Many cross-dock operations require large staging areas where inbound materials are sorted, consolidated, and stored until the outbound shipment is complete, and ready to ship. If the staging takes hours, or a day the operation is usually referred to as a cross-dock distribution center. If the operation takes several days, or even weeks, the operation is considered a warehouse.
