Overweight trailer rework in New Jersey means stripping a container that exceeds US road weight limits, re-palletizing and splitting the freight across two trailers, and redistributing the load so every axle group is legal before the truck leaves the yard. The federal gross limit on the Interstate System is 80,000 lbs, with 20,000 lbs on a single axle and 34,000 lbs on a tandem group. Nexus Warehouse does this rework at 99 Kero Rd in Carlstadt, NJ, 15 miles from Port Newark, so the fix happens near the terminal instead of at a scale house.
Why a container that was legal at origin is illegal here
Ocean carriers load to the box. A 40-foot container has a payload rating stamped on the door, and a shipper overseas can fill it to that rating without breaking a rule of the ocean move. The box is legal on the vessel, legal on the crane, legal on the terminal stack.
Then it gets mounted on a chassis. Now you are not weighing cargo, you are weighing tractor plus chassis plus container plus cargo as one combination vehicle on a public highway. The equipment alone eats a large share of the 80,000 lbs before a single carton goes in. That leaves far less legal payload than the container’s plate suggests, and the gap is where most overweight problems come from. Nobody made a mistake. The load was built for a different set of rules.
The Port of New York and New Jersey moved 8.89 million TEUs in 2025 as the second-busiest US gateway, according to the Port Authority of NY & NJ. At that volume, heavy boxes are not an edge case. They arrive every week: tile, stone, beverages, canned goods, machinery, anything dense enough to hit weight before it hits cube.
What overweight rework physically involves
Rework is not paperwork. It is labor on a dock, and it runs like this:
- Strip the container. Floor-loaded freight comes out by hand; palletized freight comes out by forklift.
- Palletize or restack. Loose cartons get built onto pallets so the weight is countable. Overbuilt pallets get broken down to a workable weight each.
- Split the freight across two outbound trailers, or hold a portion in storage so the first trailer runs legal.
- Reload with the axles in mind. Heavy pallets go where they belong relative to the kingpin and the tandems, not simply nose to tail.
- Document the count and the split so receiver and carrier see the same numbers.
The split is where the value sits: one 44,000 lb container becomes two legal outbound loads, or one legal load plus a stored balance on a later truck.Pallet handling at Nexus is $10 per standard pallet in and $10 per standard pallet out, and the first two hours of storage on arrival are free. Full rates are on the pricing page. If your box needs a certified weight ticket produced on site, say so before you dispatch — that is arranged case by case, not assumed.
The Bridge Formula trap
Here is the part that catches experienced shippers. Weight distribution across axles is governed by the Federal Bridge Formula, so a truck can scale under 80,000 lbs gross and still be illegal because the weight sits wrong across the axle groups. A box loaded heavy in the nose overloads the drives; heavy in the doors, it overloads the chassis tandems. Same total, different outcome at the scale.
| Federal limit (Interstate System) | Maximum weight | What it applies to |
|---|---|---|
| Gross vehicle weight | 80,000 lbs | Tractor, chassis, container and cargo combined |
| Single axle | 20,000 lbs | Steer axle or any standalone axle |
| Tandem axle group | 34,000 lbs | Drive tandems; chassis tandems |
| Axle distribution | Federal Bridge Formula | How weight may be spread between axle groups |
That is why sliding the tandems is the first move a driver tries, and why it often is not enough. Sliding shifts weight between groups; it does not remove weight from the combination. Once the box is over gross, the only answer is taking freight out of it.
Fixing it near the port versus finding out at the scale house
Reworking 15 miles from Port Newark is a scheduled event. You know the cost, you know the pallet count, and the outbound trucks leave on your plan. Discovering the problem at a weigh station is not. The truck stops where it stands, the load cannot move until it is corrected, and you are sourcing a trailer, a forklift and labor in whatever county the scale sits in, at short-notice rates. Add detention, the missed appointment, and the citation.
The rule most importers land on: if declared cargo weight plus tractor and chassis puts you anywhere near 80,000 lbs, route the box to a warehouse first and let it go out as two legal loads. That work pairs with cross-docking, transloading and freight consolidation off the same dock. The full list is on the services page. Hours are 8:00 AM to 5:00 PM, seven days, with a 9 PM daily cutoff; the phone is 877-456-4113.

Common questions
How much can a 40-foot container actually carry legally on US roads?
It depends on the tractor and chassis, because the 80,000 lb federal gross limit covers the whole combination. After equipment weight, legal cargo payload is commonly in the low-to-mid 40,000 lb range, under what many container door plates allow. Weigh the actual combination rather than trusting the plate.
Can you be under 80,000 lbs and still get cited?
Yes. The Federal Bridge Formula governs how weight is distributed across axle groups, and single axles are capped at 20,000 lbs with tandem groups at 34,000 lbs. A load that is under gross but stacked heavy over one group is still out of compliance.
How fast can an overweight container be reworked in Carlstadt?
A standard strip, restack and split into two outbound trailers is typically a same-day job when the box arrives inside operating hours and outbound equipment is arranged. The 9 PM daily cutoff sets the same-day deadline. Call 877-456-4113 with the container number, weight and piece count for a firm answer.
