Weight facts
Provide container size, gross weight, cargo weight if known, import status, and any scale information already available.
Special equipment by review
Overweight Import Container Drayage
Overweight import containers are reviewed individually because legal weight, route, chassis, receiver access, and equipment availability can change the move. Send the gross weight, container size, delivery address, timing, and import status before requesting a truck.
What determines whether an overweight import fits.
For Overweight Container Drayage, provide the equipment, access, timing, receiver, and closeout details that apply.
Pickup and route
Identify the marine terminal or rail ramp, delivery address, known route constraints, and whether tri-axle equipment is requested.
Receiver and closeout
Send the appointment, entrance limits, unload plan, time on site, chassis return, and empty-container instructions. Export moves should stay legal weight.
Overweight import work is accepted only after route and equipment review.
A weight figure alone does not confirm the move. Dispatch must verify legal fit, available chassis or tri-axle equipment, receiver access, timing, and the complete lane.
Cargo-weight planning
