The record

Product: ContainerMath provides 3D load planning for cartons and shipping containers, turning cargo lists into optimized load plans.
Carton Fit: Carton Fit packs products into cartons or crates and reports units per box and boxes needed.
3D and 2D plans: Plans include an interactive 3D placement view, a 2D cross-section and a share link that can open the load in augmented reality.
Packing engine: The site says its extreme-point algorithm handles mixed box sizes, stacking, orientations and pipe nesting, and can suggest a mixed fleet when the last container would be nearly empty.
Cargo types: Supported freight includes boxes, pallets, crates, bars, pipes, rolls, drums, bottles, IBC totes, sacks, big bags and pouches.
Vessel coverage: ContainerMath lists more than 50 vessel types across sea, road, rail and air ULDs.
Manifest import: AI manifest import parses sizes, weights and quantities from pasted dispatch lists, packing lists or spreadsheets.
Weight checks: Plans include center of gravity, and road vehicle plans include per-axle weights with a search for a legal re-stow when an axle limit is exceeded.
Documents and automation: Pro Plus includes export documents, a lane calendar, webhooks and an embeddable widget; export document formats cover nine jurisdictions.
Integrations: The REST API is intended to run load planning from systems such as SAP, NetSuite, a TMS, CRM or internal tools; API keys require a company account using a work email address.
API limits: Pro Plus API use is limited to 2,000 requests per month, while Custom has unlimited requests; the API does not generate shipment documents or compare equipment options.
Security: The privacy policy says connections use HTTPS and account data, saved plans, cargo data and presets are stored on managed infrastructure with access controls.
AI data handling: When AI features are used, cargo details, packing-list text or files, and submitted prompts are sent to a third-party AI provider.
Support: ContainerMath says it typically responds to support requests within 24 hours.
Price from: $39.99/mo
