ContainerMath
ContainerMath turns cargo lists into load plans for cartons, crates and shipping equipment.
What ContainerMath is
ContainerMath turns cargo lists into load plans for cartons, crates and shipping equipment. Its Carton Fit tool packs products into cartons or crates and reports units per box and the number of boxes needed. Plans show an interactive 3D placement view, a 2D cross-section and a share link that can open the load in augmented reality. The packing engine supports mixed box sizes, stacking, orientations and pipe nesting, and can suggest a mixed fleet when the final container would be nearly empty. It covers boxes, pallets, pipes, rolls, drums and other listed freight, with more than 50 vessel types across sea, road, rail and air ULDs. AI manifest import reads sizes, weights and quantities from pasted lists or spreadsheets. Plans include center of gravity; road plans also show per-axle weights and can search for a legal re-stow if an axle limit is exceeded. A free trial gives four one-time calculations without a credit card. Starter is $39.99 a month; Pro Plus is $129 a month.
