When a drayage invoice comes in higher than expected, the instinct is to look at the carrier’s rate. Often the more productive place to look is your own receiving dock.
Waiting time, detention, per diem, and repositioning charges are all downstream of how quickly a container gets unloaded and released. Those are the line items you have the most direct control over — and they usually add up to more than any rate negotiation would deliver.
The three clocks running at your dock
1. Driver waiting time
On a live unload, the driver is on your site with the truck, the chassis and the container. Most carriers allow a free window — commonly one to two hours — and bill by the hour or fraction thereafter.
The cost isn’t just the waiting charge. A driver stuck for four hours has lost the second move of the day, and that lost capacity gets priced into your rates over time whether or not it appears as a line item.
2. Per diem on the ocean container
The ocean carrier’s equipment accrues per diem for every day it’s out beyond free time. If your dock takes three days to unload a container, you’re paying for three days of a box you no longer need.
3. Chassis rental
If the chassis is on a daily rental, it bills alongside the container. A container sitting on your yard is two meters running, not one.
What actually creates dock delay
The usual causes, roughly in order of frequency:
- Floor-loaded containers. Hand-unloading a floor-loaded 40-foot container takes hours. A palletized container takes minutes. This is decided at origin, by your supplier, months before the container reaches you.
- No appointment discipline. Three trucks scheduled for the same window and one dock door means two of them wait.
- Labor timing. Deliveries arriving when the crew is at lunch or at shift change.
- Paperwork at the door. Checking in, finding the PO, locating the right person — time that should be handled before the truck arrives.
- Count-and-inspect at the door. Detailed inspection while the driver waits, when the cargo could be moved inside and inspected afterward.
- Space. Nowhere to put the freight because the dock area is full.
The fixes, in order of payoff
Palletize at origin
The single largest lever. Ask your supplier to load on pallets rather than floor-loading. You’ll lose some cubic capacity per container and gain hours per unload. On most freight the arithmetic strongly favors pallets. Where suppliers won’t or can’t, transloading near the port converts the problem into someone else’s specialized operation.
Switch to drop-and-hook
Have the container dropped and unload it on your own schedule. The driver’s clock stops immediately. The container’s per diem clock keeps running, so this works when you’ll unload within a day or two — not as a substitute for a warehouse. Our comparison of drop-and-hook vs. live unload covers the trade-off.
Book appointments before pulling
Set the receiving appointment first, then schedule the terminal pickup against it. Doing it the other way around means containers arrive when your dock isn’t ready.
Prepare paperwork in advance
Send the delivery order, PO reference and container number to your receiving team the day before. Every minute spent looking things up at the gate is billable.
Unload first, inspect second
Get the freight off the truck and release the driver, then do your detailed count and inspection. Note any visible damage or seal discrepancy on the delivery receipt before the driver leaves — that part does have to happen at the door — but a carton-by-carton count does not.
Return empties immediately
Once devanned, the empty should go back. An empty container sitting on your yard is pure cost.
Measure it
If you’re not tracking dwell, you can’t manage it. Three numbers worth watching:
- Average driver time on site, by day of week and hour of arrival
- Average container days out from terminal pickup to empty return
- Accessorial charges as a percentage of total drayage spend
That last one is the summary metric. If accessorials are a large share of your drayage bill, the problem is operational rather than commercial. Our line-by-line guide to drayage accessorials explains what each charge is, and drayage KPIs covers what else to measure.
When the dock isn’t the answer
Sometimes the honest conclusion is that your facility isn’t set up for container receiving, and forcing it is expensive. In that case, transloading near the port — devanning the container and delivering palletized freight on domestic equipment — moves the hard part to a facility built for it.
Go Drayage’s five-acre Miami yard has forklifts rated to 19,000 and 40,000 lbs and 24/7 access for exactly this work. See drayage services for the full picture.
Frequently asked questions
How much free time do drivers get at a receiving dock?
It varies by carrier and should be specified in your rate agreement, but one to two hours is a common allowance for a live unload, with hourly waiting charges after that. Check what your agreement actually says rather than assuming an industry standard.
Is drop-and-hook always cheaper than live unload?
It removes driver waiting time, but the container keeps accruing per diem while it sits at your facility. It’s cheaper when you unload within a day or two and more expensive when the container becomes de facto storage.
What’s the fastest way to reduce drayage accessorial charges?
Cut the time containers spend at your facility. Palletized loading at origin, appointments booked before the container is pulled, and immediate empty returns typically deliver more savings than renegotiating the base rate.
