Freight answersCross-Docking
What Are the Main Types of Cross-Docking?
Short answer
Cross-docking is usually classified by when each unit's destination is decided: in pre-distribution cross-docking the destination is set before the freight arrives, and in post-distribution the freight is sorted and allocated at the dock. It is also described by process (continuous flow, consolidation or deconsolidation) and by who prepares the loads, the supplier or the cross-dock operator.
By when the destination is decided
| Pre-distribution | Post-distribution | |
|---|---|---|
| Destination decided | Before the goods arrive | At the cross-dock |
| Work at the dock | Mostly transfer: freight is already built by destination | Sorting and allocating by destination |
| Suits | Stable, planned orders | Demand that changes after shipment |
Maersk puts it this way: "In pre-distribution, the end destination is decided before the goods arrive at the cross-dock facility," while "post-distribution involves sorting and allocating products to their next destinations at the cross-docking terminal."[1] Academic work on cross-docking uses the same split.[3]
By who prepares the loads
A widely cited typology from a Warehousing Education and Research Council study, as summarized in an academic chapter, has three types: pre-allocated supplier consolidation, pre-allocated cross-dock operator consolidation and post-allocated cross-dock operator consolidation. "When the product is pre-allocated, its destination is determined at the supplier; when the product is post-allocated, its destination is determined at the [cross-dock facility]."[2]
By process
Cross-docking can also be described as continuous (freight flows straight through), consolidation (small inbound loads combined into larger outbound ones) or deconsolidation (a large inbound load split into smaller ones).[1] LTL carriers run consolidation cross-docks at scale: most shipments pass through regional hubs where freight joins other freight going the same way.[5]
What makes any type work
A study of cross-dock supply chains names success factors including "speed, effective planning, high reliability, accurate processes and a high degree of transparency, visibility and information-sharing."[4] In plain terms: the outbound side has to be confirmed before the inbound truck arrives.
Example
A retailer's suppliers ship pallets already labeled by store: pre-distribution, and the dock simply transfers them. After a promotion changes store demand, the retailer switches some lanes to post-distribution, and the dock breaks inbound pallets down and builds new ones by store.
Limitations
These categories overlap in practice, and a single facility often runs several at once.
