Freight Glossary
Lumper Service
Lumper service refers to hired labor, typically at a receiving facility, that unloads freight from a truck on behalf of the driver. Lumpers are commonly used at grocery DCs and retail warehouses where drivers are not permitted to unload. The lumper crew physically moves pallets or cases off the truck and onto the dock, then the driver is released to continue their route.
Why it matters
Lumper costs can add $100 to $400 per load to unplanned expenses, and many shippers are surprised to find that their carrier passes these costs through as an accessorial charge if not addressed upfront in the freight agreement. For shippers delivering 50+ loads per month to grocery DCs, unmanaged lumper fees can quietly add $60,000 or more in annual freight spend.
When to use it
Anticipate lumper requirements when shipping to grocery distribution centers, big-box retail DCs, or any receiver that does not allow driver unload. Confirm responsibility and payment terms before the shipment moves. Before onboarding a new retail account, ask whether the receiving facility uses lumpers and who is expected to pay so you can factor it into your landed cost.
How Warp thinks about it
Warp's cross-dock facilities handle the physical movement of pallets through its own cross-dock operations. Lumper costs at customer-operated receiver facilities are a separate consideration for shippers to confirm. With 50+ cross-docks staffed by Warp teams, freight moves through the Warp network without third party lumper involvement.
