Drayage Explained: What It Is, How It's Priced, and Why It Matters for Your Supply Chain

Drayage is one of those supply chain terms that sounds technical but describes something straightforward: the short movement of freight, typically by truck, from one point to another within the same metro area. Most commonly, it refers to container movement from a port or rail yard to a nearby warehouse or distribution center — or vice versa.

It’s a small piece of the overall supply chain journey, but drayage is frequently where delays happen, where unexpected costs accumulate, and where importers lose control of their cargo after it arrives. Understanding how drayage works and what drives its cost is essential for anyone managing ocean freight.

What Is Drayage?

Drayage refers specifically to the short-haul truck transport of freight, typically containers, over a relatively short distance — usually within a single metropolitan area or port region. The term originated in the 19th century, when goods were moved short distances by a dray (a low, flat horse-drawn cart).

In modern logistics, drayage most commonly refers to:

Port drayage: Moving a container from a seaport terminal to a nearby warehouse, distribution center, or intermodal rail facility. This is the most common form.

Rail drayage: Transporting containers between a rail yard and a final destination nearby.

Door-to-door drayage: Moving goods between two facilities within the same metro area, often as the final leg of a larger shipment.

Shuttle drayage: Short container movements within port or terminal facilities — moving containers between terminals, staging areas, or storage yards within the same port complex.

The defining characteristic of drayage is distance: it’s typically under 100 miles, often under 50, and frequently much shorter. What makes it logistically complex is everything that happens around that short trip: port terminal appointments, chassis availability, container availability, congestion, and demurrage risk.

How Drayage Fits Into the Import Process

When a shipment arrives at a US port by ocean, the container sits in the terminal until it’s picked up. The typical sequence:

1. The vessel arrives and the container is discharged to the terminal
2. Customs clearance (through your customs broker) must be completed before release
3. The container is available for pickup once released by Customs
4. A drayage carrier picks up the container from the terminal
5. The container moves to your warehouse or DC
6. The container is unloaded and returned to the terminal or equipment depot

The drayage move itself — step 4 to 5 — is the short-haul truck move. But the surrounding steps (getting a terminal appointment, finding chassis, coordinating timing) are where complexity and cost accumulate.

Drayage Pricing: How It Works

Drayage is not a commodity service with transparent pricing. Rates vary significantly by port, carrier, distance, chassis arrangements, and current market conditions. Understanding the components helps you evaluate quotes more accurately.

Base drayage rate

The core charge for picking up and delivering the container. Typically based on the distance from port to destination (in zones, not exact mileage) and the container size (20-foot TEU vs. 40-foot FEU). Published rates by zone are the starting point — actual invoiced amounts often exceed the base rate due to accessorials.

Chassis charges

In the US, most drayage moves require the trucking company to provide a chassis (the wheeled trailer frame that the container sits on). Chassis are not provided by the port — they’re managed by chassis pools operated by leasing companies, ocean carriers, or chassis pool operators (ILA/ILWU agreements affect availability significantly).

Chassis rental: typically $15-35/day. If there’s a chassis shortage (common at congested ports), chassis can be unavailable for days, and the daily charges add up.

Fuel surcharge

Applied as a percentage of the base rate, indexed to weekly diesel fuel prices. Published by the FMCSA and adjusted by carriers at defined intervals.

Port congestion surcharge

At ports experiencing significant congestion (vessels waiting at anchor, terminal gates backed up), carriers often apply a congestion surcharge — typically $100-300 per move — to cover the additional driver time and chassis costs.

Detention and per diem

If your container isn’t unloaded within the free time allowed (typically 2-4 hours at your facility), you’re billed detention — the driver’s waiting time, typically $75-100/hour after the free time window.

Per diem is charged by the ocean carrier for using their container (or a pool chassis) past the agreed return date. Per diem rates vary by carrier and equipment type — typically $50-200/container/day and can escalate significantly if the container isn’t returned quickly.

Chassis split charge

If the chassis pool is separate from the terminal where your container is held, the driver may need to pick up a chassis at one location and the container at another — a “chassis split.” This adds $75-150+ per move.

Overweight/overlength charges

Containers exceeding legal road weight limits require special permits. Overweight surcharges vary by state and can be $150-500+ per move for heavy cargo.

Hazmat handling

Containers with hazardous materials require certified drivers and additional documentation, adding a hazmat surcharge — typically $100-250+.

What Drives Drayage Costs Up

Shippers who struggle with unpredictable drayage costs are usually dealing with one or more of these:

Free time management: Ocean carriers grant a limited number of free days for the container at the terminal (typically 3-5 days, varying significantly by carrier and port). Every day past free time incurs per diem. Shippers who don’t have their drayage carrier coordinated before the vessel arrives consistently burn free days and accumulate per diem.

Terminal appointments: Most major US ports now require advance appointments for container pickup. Appointment slots are limited and get booked quickly after vessel arrival. Drayage carriers without established relationships or systems for booking appointments miss slots, containers sit, and per diem accumulates.

Chassis availability: At ports with chronic chassis shortages (Los Angeles/Long Beach being the most notorious), finding a chassis for a particular container can take days. Shippers using carriers with established chassis pools — through the local chassis pool operators or their own chassis — have better availability.

Congestion: Port congestion directly translates to longer driver dwell times, fewer turns per driver per day, and ultimately higher rates and surcharges across the market.

Vessel delays and late arrivals: When a vessel arrives late, the container arrival is compressed against the free time window. Importers who planned their pickup for a specific date need to scramble.

Drayage vs. LTL vs. FTL: What’s Different

Drayage, LTL, and FTL all involve trucks, but they operate in different markets with different pricing structures:

Drayage is a specialized market focused on container movement around ports and rail yards. The drivers are typically owner-operators or company drivers who understand port operations, terminal appointments, and container handling. Equipment (chassis) is a key variable. Per diem and detention risk don’t exist in LTL or FTL.

LTL is a shared-load carrier network for freight that doesn’t fill a full trailer. Pricing is based on freight classification, weight, and lanes. LTL carriers don’t typically touch port containers.

FTL is a full-trailer point-to-point move. If you’re doing a first-mile move from a port container to a DC and then reloading for cross-country truckload, you’d use drayage for the port move and FTL for the long-haul segment.

The modes often connect: drayage moves a container from the port to a transload facility, where the goods are reloaded from an ocean container into a domestic 53-foot trailer for the FTL or LTL movement inland.

Transloading: The Alternative to Direct Drayage

For importers shipping to destinations far from port, transloading — unloading the ocean container and reloading into domestic trailers at a facility near the port — is often more cost-effective than dragging the heavy ocean container across the country.

Advantages of transloading:

• Domestic trailers are more efficient for inland movement than ocean containers
• Avoid returning the ocean container across the country
• Can combine partial containers from multiple shipments into fewer domestic loads
• Access to larger domestic trailers (53’ vs 40’ ocean container)

Trade-off: The transload facility adds a handling step and cost. Whether it pencils out depends on origin/destination, volumes, and the cost delta between container-on-chassis moves and domestic truckload.

How to Manage Drayage Costs Effectively

Work with a drayage carrier before the vessel arrives. The window to book a terminal appointment and arrange chassis opens when the vessel is tracking to arrival. Shippers who don’t engage their drayage carrier until the container is released lose days of free time.

Track your containers. Ocean carrier tracking systems show container status — discharged to terminal, available for pickup, released by Customs. If you’re not monitoring status, you discover delays after per diem has already started accumulating.

Use your TMS for drayage coordination. Modern TMS platforms integrate with port tracking and drayage carrier systems. Automated alerts when a container is available and appointment booking workflows prevent the manual coordination gaps where per diem accumulates.

Understand your free time by carrier. Every ocean carrier grants different free time at different ports. Know your carrier’s policy by port before you book a shipment — particularly for slow-moving goods where the container may sit.

Audit your drayage invoices. Accessorial charges (chassis splits, chassis shortages, congestion surcharges) are sometimes applied inconsistently or incorrectly. A systematic invoice audit against the contracted rate schedule and documented conditions catches billing errors.

Negotiate per diem risk into your purchasing agreements. If your DC doesn’t have the capacity to unload containers quickly, or if your receiving schedule is unpredictable, build that risk into your supplier terms or your DC operating model — don’t absorb it passively as a logistics cost.

The Port Congestion Problem

Drayage costs and reliability are heavily influenced by port congestion, and the past several years have demonstrated how dramatically port conditions can affect supply chain economics.

The Los Angeles/Long Beach port complex handles roughly 40% of US containerized imports. Congestion at this complex — measured in vessel anchorage queues, terminal dwell times, and chassis shortages — directly translates to elevated drayage costs, per diem accumulation, and supply chain delays for a significant share of US importers.

Importers with heavy port concentration exposure should understand their drayage carrier’s relationships at their primary ports, maintain buffer stock to absorb transit uncertainty, and monitor supply chain tariff changes that affect trade flows through specific ports.

The Bottom Line

Drayage is a short move with a disproportionate ability to generate unexpected costs and supply chain disruption if not managed proactively. The base rate is only part of the picture — chassis charges, per diem, detention, and congestion surcharges are where budgets get blown.

The fundamentals of drayage management are simple: engage your drayage carrier before the vessel arrives, track your containers, understand your free time windows, and audit invoices against contracted rates. Shippers who do these consistently outperform those who treat drayage as an afterthought.
