What Is Cross-Docking?
Cross-docking is a logistics practice where products are unloaded from inbound vehicles and loaded directly onto outbound vehicles with little or no storage time in between.
Types of Cross-Docking
Manufacturing Cross-Docking
- Receiving components from multiple suppliers
- Consolidating for delivery to production line
- Just-in-time inventory support
Distributor Cross-Docking
- Combining products from multiple vendors
- Creating mixed-SKU shipments for customers
- Retail distribution center model
Transportation Cross-Docking
- Consolidating LTL shipments into full truckloads
- Hub-and-spoke network efficiency
- Carrier terminal operations
Retail Cross-Docking
- Pre-allocated merchandise from vendors
- Store-ready shipments
- Minimal handling at distribution center
Benefits of Cross-Docking
- Reduced inventory: Less need for warehouse storage
- Lower handling costs: Products touched fewer times
- Faster delivery: Reduced dwell time
- Fresher products: Important for perishables
- Reduced storage costs: Smaller facilities needed
