One of the most common "surprise" lines on a drayage invoice, explained — and how to make it disappear.
You get a drayage quote, the box moves, and the invoice shows a charge you didn't expect: chassis split. It's one of the most common surprise fees in container drayage, and it catches importers off guard because it has nothing to do with the freight itself — it's about where the equipment is. The good news: it's usually avoidable.
To move a container by road, the box has to sit on a chassis — the wheeled frame underneath. Ideally the container and an available chassis are in the same place, and the driver hooks up and rolls. A chassis split happens when they're not together: the chassis is at a different pool, depot or terminal than the container. The driver has to make a separate trip to grab a chassis before pulling the box — and that extra trip is the fee.
Chassis at the Northwest Seaport Alliance terminals come from shared pools, and supply tightens during peak season and congestion. When the right chassis type isn't available at the terminal where your container is, a split is forced. Overweight and specialty boxes make it more likely, because they need specific chassis (like tri-axle for overweight loads) that aren't always on site.
A chassis split is mostly a planning problem, so we plan around it:
Know the chassis need before dispatch — container type and weight tell us which chassis is required, so we source it ahead instead of discovering the gap at the gate.
Use the right pool — matching the move to the pool where the equipment actually is.
Prepull and stage — when timing is tight, pulling the box early to our Kent yard lets us marry it to a chassis on our schedule, not the terminal's.
Drop-and-hook for steady lanes — keeping a chassis under recurring freight removes the split entirely.
None of this is exotic — it's just dispatch discipline. Because we run drayage in-house and watch the equipment as closely as the freight, a chassis split is the exception, not a line you brace for.
A charge for the extra trip a driver makes when the chassis and the container aren't in the same place — the driver has to pick up a chassis from another pool or depot before pulling your box.
It varies by terminal and distance, but it's a real added line every time — which is why avoiding it through planning matters more than the exact figure.
Usually yes — by sourcing the right chassis ahead of dispatch, using the correct pool, prepulling when timing is tight, or running drop-and-hook on steady lanes.
They need specific chassis (such as tri-axle) that aren't always staged at the terminal, so a separate trip to get the right equipment is more often required.
