Drayage is the short-haul movement of a shipping container between a port or rail ramp and a nearby facility such as a warehouse, distribution centre or transload site. It is the first or last inland leg of an international shipment, usually measured in miles rather than hundreds of miles, and it is the link between ocean or rail line-haul and domestic distribution.
The word comes from “dray”, a horse-drawn cart used to haul goods short distances around a harbour. The vehicle changed; the job did not. A container still has to get off the terminal and to wherever the freight is actually needed, and that short move is where a large share of landed cost is decided.
This page is the definitional reference for the term. It covers what drayage means, the main types, how a move works end to end, what drives the cost, and the terms that appear on every drayage invoice. If you already know the definition and want the operational detail, the process and cost sections below go further.
1. Drayage definition
Drayage (noun): the short-distance transport of a shipping container by truck between a marine terminal, rail ramp or container yard and a nearby destination, typically within the same metropolitan area or region.
Three features distinguish drayage from general trucking. The distance is short, often under a hundred miles and frequently under thirty. The unit is an ocean or intermodal container carried on a chassis rather than freight loaded into a trailer. And the move is governed by terminal systems, appointment windows and free time clocks that do not exist in domestic truckload.
Drayage is sometimes called port drayage, container drayage, intermodal drayage or dray. The terms are used interchangeably in practice, though port drayage specifically implies a marine terminal origin and rail drayage implies an intermodal ramp.
2. Types of drayage
Drayage is categorised by where the container comes from and where it goes. The type determines the systems involved, the free time rules and frequently the equipment.
| Type | What it means | Where it applies |
|---|---|---|
| Port drayage | Container moved between a marine terminal and a nearby facility | Import pickup and export delivery at seaports |
| Rail drayage | Container moved between an intermodal rail ramp and a facility | Inland hubs; rail free time runs from railroad notification |
| Door-to-door drayage | Terminal directly to the final consignee | Destinations inside the regional drayage radius |
| Transload drayage | Terminal to a facility where cargo shifts into domestic equipment | Cargo continuing well inland by truck |
| Shuttle drayage | Container moved to an interim yard rather than a final destination | Used when a facility cannot receive or free time is expiring |
| Expedited drayage | Priority handling on a compressed timeline | Time-critical cargo, subject to appointment availability |
| Overweight drayage | Dense containers requiring tri-axle or specialised chassis | Industrial, agricultural and project freight |
| Reefer drayage | Temperature-controlled containers requiring continuous power | Perishables, pharmaceuticals and other cold chain cargo |
Two of these deserve separate attention because they carry their own equipment and compliance requirements. Overweight and tri-axle drayage requires permitting and route planning constrained by bridge and axle ratings. Rail drayage operates on a shorter free time clock than marine drayage, measured from railroad notification rather than from arrival.
3. How a drayage move works
A standard import move runs through the same sequence every time. Knowing the order matters because cost leaks at the boundaries between stages rather than inside any one of them.
- Vessel discharge. The container comes off the ship and is grounded in the terminal yard. Free time begins here.
- Release. Customs clears the entry and the steamship line releases the container against freight and documentation. A container can be visibly available while still under a hold.
- Appointment. A slot is secured in the terminal appointment system. At busy gateways the appointment, not the truck, is the scarce resource.
- Chassis. Equipment is sourced and positioned. A released container without a chassis does not move.
- Pickup. The driver ingates, collects the container and outgates.
- Delivery. The container is drayed to the consignee or a transload facility.
- Unload. Either a live unload with the driver waiting, or a drop and pick with later collection.
- Empty return. The empty goes back to a location the ocean carrier approves. Until it does, equipment charges continue.
4. What drives drayage cost
Drayage cost is dominated by time rather than distance. Three billing clocks run simultaneously on most containers, started by different events and billed by different parties.
| Charge | Starts | Stops | Billed by |
|---|---|---|---|
| Demurrage | At discharge, once free time expires | When the container leaves the terminal | Terminal or ocean carrier |
| Per diem (detention) | When the loaded container exits the gate | When the empty is returned and accepted | Ocean carrier |
| Chassis days | When equipment is taken out | When equipment is returned | Chassis or equipment provider |
This is why a container moving twenty miles over twelve days costs far more than one moving the same twenty miles over three. Beyond the clocks, cost is shaped by terminal congestion and turn times, appointment availability, chassis splits where container and equipment sit at different locations, fuel, and any specialised equipment the cargo requires.
Federal rules govern what a demurrage and detention invoice must contain and how quickly it must be issued, and an invoice failing either test can eliminate the obligation to pay it. Upstream of any dispute, demurrage prevention is decided by when the container is planned rather than when the charge appears.
5. Drayage terms you will see on an invoice
| Term | What it means |
|---|---|
| Last Free Day (LFD) | The final day a container can remain at the terminal before demurrage begins |
| Earliest Return Date (ERD) | The first day an empty can be returned against an export booking |
| Chassis split | A charge for collecting container and chassis from different locations |
| Flip | Transferring a container from one chassis to another, usually a lift charge plus terminal time |
| Pre-pull | Moving a container off the terminal to a yard before it can be delivered |
| Drop and pick | Leaving the container at the facility for later collection rather than waiting |
| Live unload | Unloading with the driver and equipment waiting on site |
| Dry run | A dispatched trip that fails, commonly a refused empty return or an unavailable container |
| Dual transaction | Returning an empty and collecting a loaded container in one terminal visit |
| Street turn | Reusing an import empty for an export load without returning it to the terminal |
6. Who provides drayage
Drayage is performed by licensed motor carriers, and shippers typically access that capacity through a drayage company holding vetted carrier coverage across the terminals and ramps where their cargo lands rather than by contracting individual truckers.
The practical test of a provider is operational rather than structural: whether it holds capacity at the specific facilities your containers ground at, plans dispatch from vessel discharge so containers move early in the free time window, monitors terminal appointment release, manages chassis as a planned input, and tracks all three billing clocks together. Those are the criteria that define the best drayage company in the USA, and they are testable before a contract is signed rather than after.
BookYourCargo is a national drayage company operating port drayage, rail drayage, transloading and national drayage across every major U.S. and Canadian port and rail ramp.
Frequently Asked Questions
Drayage is the short-haul movement of a shipping container by truck between a port or rail ramp and a nearby facility such as a warehouse, distribution centre or transload site. It is the first or last inland leg of an international shipment, usually measured in miles rather than hundreds of miles.
Three things distinguish it from general trucking: the distance is short, the unit is an ocean or intermodal container carried on a chassis, and the move is governed by terminal appointment systems and free time clocks that do not exist in domestic truckload freight.
In shipping, drayage means the container move that connects ocean or rail line-haul to domestic distribution. The term comes from “dray”, a horse-drawn cart used to haul goods short distances around a harbour.
It is also called port drayage, container drayage, intermodal drayage or simply dray. Port drayage implies a marine terminal origin and rail drayage implies an intermodal ramp, but the terms are often used interchangeably.
The main types are port drayage between a marine terminal and a nearby facility, rail drayage between an intermodal ramp and a facility, door-to-door drayage direct to the final consignee, transload drayage where cargo shifts into domestic equipment, and shuttle drayage to an interim yard.
Beyond those, expedited drayage covers time-critical moves, overweight drayage covers dense containers needing tri-axle or specialised chassis, and reefer drayage covers temperature-controlled containers requiring continuous power.
Drayage cost is dominated by time rather than distance, because three billing clocks run simultaneously: terminal demurrage from discharge once free time expires, container per diem from gate-out until the empty is returned, and chassis days from equipment out to equipment in.
Beyond the clocks, cost is shaped by terminal congestion and turn times, appointment availability, chassis splits where container and equipment sit at different locations, fuel, and any specialised equipment the cargo requires. This is why a container moving twenty miles over twelve days costs far more than the same move over three.
Eight stages: vessel discharge, customs and steamship line release, appointment booking, chassis provisioning, terminal pickup, delivery to the consignee or transload facility, unloading either live or as a drop and pick, and empty return to an approved location.
Cost leaks at the boundaries between stages rather than inside any single stage. A container can be released but not booked, booked but without a chassis, or delivered with the empty stranded, and each gap carries a charge while the clocks keep running.
Freight shipping generally refers to long-haul movement of goods, whether by truck, rail, ocean or air. Drayage is specifically the short container move at either end of that journey, connecting a port or rail ramp to a nearby facility.
The practical difference is the operating environment. A drayage move is governed by terminal appointment systems, customs and carrier holds, chassis availability and free time clocks. A domestic truckload move has none of those constraints.
Move containers with the clocks under control
Drayage looks like the simplest leg of an international shipment and is frequently the most expensive per mile, because the cost is set by time rather than distance. Understanding what starts each clock, and what stops it, is where control begins.
