Drayage is the short truck move of a shipping container between a port or rail ramp and a nearby warehouse, yard or terminal. It is the first leg an import takes on land, and the leg where extra charges pile up fastest. We explain the types of drayage, how a move runs, the 2 clocks behind demurrage and detention, and how to read a drayage quote line by line.

Quick summary

  • Drayage moves a container a short distance, usually within one metro area, between a port or rail terminal and a warehouse, yard or another terminal.
  • An ocean import usually needs drayage at both ends: from the factory to the origin port, and from the destination port to the warehouse.
  • A drayage quote is a base rate per container move plus accessorial charges for fuel, chassis days, pre-pulls, yard storage, waiting time and overweight loads.
  • Demurrage runs while a loaded container sits in the terminal past its free time, and detention runs while it is outside the terminal until the empty is returned.
  • Under federal rules, a demurrage or detention invoice must be issued within 30 days and carry the required details, or the billed party does not have to pay it.

What drayage means

Drayage is a short truck move of freight, almost always a shipping container, from one point in a transport chain to the next. The classic move runs from a marine terminal to a warehouse a few miles away, but a warehouse-to-rail-ramp or terminal-to-terminal move is drayage too.

An ocean import usually needs drayage twice: from the factory to the origin port, and from the US port of discharge to the warehouse. This guide covers the US end.

Types of drayage

TypeWhat movesWhen it is used
Pier or portContainer from a marine terminal to a nearby warehouse, or backMost import deliveries
IntermodalContainer between a port or warehouse and a rail rampImports moving inland by rail
ShuttleContainer to an off-dock yard to waitThe warehouse is full or terminal free time is running out
Intra-carrierContainer between 2 terminals of the same carrierTransfers inside one rail or ocean network
Inter-carrierContainer between terminals of different carriersA handoff from an ocean carrier to a railroad
Store doorContainer delivered straight to the final customer’s dockA single-destination import with no stop in between

Not every container goes to the importer’s own building. Some go to a bonded warehouse near the port, where the goods wait with the duty unpaid, and some are emptied at a transload building into 53-foot trailers for a long run inland.

How a drayage move runs

  1. Container released. Once the vessel is discharged, customs releases the goods and the ocean freight is paid, the terminal shows the container as available.
  2. Delivery order sent. The importer, forwarder or customs broker sends the dray carrier the container number, pickup terminal, last free day and delivery address.
  3. Pickup booked. The carrier books a terminal appointment where the terminal requires one, and pairs the container with a chassis from a pool or its own fleet.
  4. Delivery. The driver either waits while the container is emptied (a live unload) or leaves it on its chassis for the warehouse to unload later (a drop).
  5. Empty returned. The empty goes back to the terminal or depot the ocean carrier names, which stops the detention clock.

At the warehouse the freight is received into storage or cross-docked to outbound trucks the same day, which decides whether the building wants a live unload or a drop.

Demurrage, detention and the import clocks

Two clocks start around discharge, and most avoidable drayage cost comes from one of them running out. In common usage, demurrage is charged while a loaded import container stays in the terminal past its free time, and detention, also called per diem, while the container is outside the terminal past its free time, until the empty is returned. Free time is set by the carrier’s or terminal’s tariff, or the importer’s contract, and it varies.

The federal rules at 46 CFR part 541 treat both charges together as “demurrage or detention” when they come from ocean carriers, marine terminal operators or NVOCCs, and they set how those charges must be invoiced. The invoice has to be issued within 30 calendar days of the date the charge was last incurred, or the billed party does not have to pay it. It must show the container number, the free time with its start and end dates, the availability date, the dates charged and the tariff or contract rule, among other items, and leaving out any required item removes the obligation to pay. The billed party then has at least 30 days from the invoice date to ask for a refund or waiver.

What a drayage quote includes

A drayage quote prices the move per container, not by weight, and adds accessorials for everything around the move. Distance sets the base rate; time inflates the rest, through a driver waiting at a congested terminal, a chassis kept for extra days or a container pulled to a yard and moved twice. An importer landing containers at the Port of Savannah can hold stock at 3PLs near Savannah, a short dray from the terminal, or at a building farther inland, trading rent against a longer run on every container.

On one container whose schedule slipped, those lines add up like this:

Frequently asked questions

What is the difference between freight and drayage?

Freight is the whole shipment and the whole move; drayage is one short leg of it, the truck move between a port or rail ramp and the next stop. An import from Shanghai to Dallas might travel by ship, rail and truck, and only the truck moves to and from the terminals are drayage.

How do you pronounce drayage?

It is pronounced DRAY-ij, with the first syllable rhyming with day. The word comes from the dray, a low cart once used to haul goods from the docks.

What is drayage and demurrage?

Drayage is the truck move that takes a container out of the terminal; demurrage is the charge for leaving a loaded container in the terminal past its free time. The two are linked because a late drayage pickup is the usual cause of demurrage.

What does DND mean in shipping?

D&D, sometimes written DND, stands for demurrage and detention: the charges for keeping a container in the terminal, or out of it, past its free time. Federal rules at 46 CFR part 541 require these invoices to be issued within 30 days and to show the free time, dates and tariff rule, or they do not have to be paid.

Why is drayage so expensive?

Because the move is short but the time around it is long. Drivers wait at congested terminals, chassis are rented by the day, and missed pickup windows turn into pre-pulls, yard storage and second moves, all priced per container rather than per mile.

Who arranges drayage for an import?

Usually the freight forwarder, who books it with the ocean freight, but a customs broker, a 3PL or the importer can book it directly. Whoever books it needs the delivery order, the last free day and the warehouse appointment.

What is a pre-pull in drayage?

A pre-pull is picking up a container from the terminal before the warehouse can take it and parking it at the dray carrier's yard. It stops demurrage at the terminal but adds yard storage, chassis days and a second move, so it pays only when the demurrage it avoids is higher.
