Frequently asked questions
Volume or weight — which wins?
Whichever allows fewer cartons per trip is the limiting factor. Dense goods often hit payload first.
What is packing efficiency?
A deduction for voids, dunnage and imperfect stacking — 80–90% is a common planning range.
Is this for containers too?
No — use the Container Load Planner for 20ft / 40ft ocean equipment.
Why is empty space left?
On partial final trips, or when weight caps the load before the cube is full.
