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. Load plans include an interactive 3D placement view, a 2D cross-section, and a share link that can open the load in augmented reality. The packing engine handles mixed box sizes, stacking, orientations, and pipe nesting, and can suggest a mixed fleet when the final container would be nearly empty. Supported freight includes boxes, pallets, crates, bars, pipes, rolls, drums, bottles, IBC totes, sacks, big bags, and pouches, across more than 50 vessel types for sea, road, rail, and air ULDs. AI manifest import parses sizes, weights, and quantities from lists or spreadsheets. Plans show center of gravity; road plans also include per-axle weights and a search for a legal re-stow if a limit is exceeded. A four-calculation trial is available; Starter costs $39.99 per month.
