Drayage is the shortest leg of an import shipment and often the most expensive per mile. Understanding it is essential to controlling landed cost.

What Is Drayage?

Drayage is the short-distance transportation of freight, specifically the movement of shipping containers between a port, rail ramp, or intermodal facility and a nearby warehouse or distribution center. The term comes from historical usage (a "dray" was a low, flat cart used for heavy loads), but in modern logistics it refers almost exclusively to container moves performed by specialized drayage carriers operating within a port's local geography.

Drayage is the first or last domestic leg of an international shipment. When a container arrives at the Port of Los Angeles, it must be moved from the terminal to a distribution center before its contents can enter the domestic freight network. That move, typically 20-60 miles, is drayage. It is short, but it is not cheap.

Types of Drayage

Drayage operations fall into several categories based on the move type:

• Port drayage: the most common type. Moves a container from an ocean terminal to an off-port warehouse or directly to a shipper's facility.
• Rail/intermodal drayage: moves containers between a rail ramp (intermodal container transfer facility) and a warehouse or port terminal.
• Expedited/hot shot drayage: urgent container moves, often required when a container is blocking a terminal lane or a ship-to-DC deadline is critical.
• Door-to-door drayage: the container moves directly from the port to the consignee's receiving facility, without an intermediate warehouse stop.

How Drayage Costs Are Structured

Drayage pricing is not per mile. It is structured around the container move itself, with several components:

• Base rate: a flat fee per container move, negotiated by lane (specific port-to-destination pairs). Rates vary widely by port and availability of drayage trucks and chassis.
• Chassis fees: a daily rental charge for the chassis (trailer) used to transport the container. Chassis shortages at major ports can make this fee significant, especially if a container is not unloaded and the chassis returned quickly.
• Fuel surcharge: typically a percentage of the base rate, indexed to diesel prices.
• Port congestion charges / PierPass: at major ports like Los Angeles and Long Beach, off-peak traffic mitigation fees apply to daytime terminal gate moves.
• Per diem / demurrage: charges from the ocean carrier for keeping a container beyond its free time (typically 4-5 days after discharge). This is separate from chassis fees and accrues quickly.
• Detention: driver waiting time at the terminal gate or at the shipper's facility. Terminal gate wait times at congested ports can run 2-4 hours, generating substantial detention charges.

Drayage vs. Linehaul: What Is the Difference?

Drayage and linehaul both move freight by truck, but they are structurally different operations serving different purposes:

• Distance: drayage moves containers 5-100 miles. Linehaul moves freight across lanes that typically span 100-2,000+ miles.
• Equipment: drayage uses port-specific equipment (chassis, container-capable trucks). Linehaul uses standard 53-foot trailers or specialized equipment.
• Pricing: drayage is priced per container move, with add-ons for chassis and waiting time. Linehaul is priced per mile or per pallet.
• Carrier type: drayage carriers are typically small fleets with port authority registration requirements. Linehaul carriers operate across state lines under FMCSA authority.

The distinction matters because these two legs of a supply chain are managed and priced separately. A shipper's middle-mile carrier handles the linehaul leg; a drayage provider handles the port move. Warp operates in the middle-mile and linehaul space. After containers are drayaged to a cross-dock facility, Warp moves the palletized contents to final distribution points.

Transloading: The Bridge Between Drayage and Linehaul

Transloading is the process of devanning (unloading) an ocean container and reloading its contents into domestic trailers optimized for the US freight network. It is the operational handoff between the drayage leg and the linehaul leg.

Ocean containers are 20 or 40 feet long and loaded to international cargo specs. Domestic linehaul uses 53-foot trailers loaded to US palletization standards. Transloading at a cross-dock facility near the port converts the inbound ocean cargo into domestic pallets that can be sorted and routed by destination, enabling zone skipping strategies and bypassing slow inland rail for domestic trucking.

Warp's cross-dock network, including facilities in Los Angeles, Chicago, and Houston, is positioned to receive transloaded freight and inject it into the outbound domestic network on the same day. For importers managing inbound supply chains, this integrated drayage-transload-linehaul approach reduces dwell time and simplifies vendor management.

Reducing Drayage Costs

Drayage costs are driven heavily by factors outside the shipper's control: port congestion, chassis availability, labor actions. The controllable levers are:

• Minimize free time exposure by scheduling drayage appointments before the container discharges, not after.
• Use off-peak terminal appointments where available to avoid PierPass and peak congestion fees.
• Negotiate chassis pools with your drayage carrier to avoid daily chassis rental charges on extended unload cycles.
• Build transloading into your inbound flow to eliminate ocean container per diem by returning containers quickly after transload.

For manufacturing and CPG importers with regular container volume, coordinating between freight forwarding on the ocean leg and the inbound vendor consolidation model on the domestic side integrates drayage, transload, and distribution into a single managed program.
