Optimizer

Package size optimizer

Searches every combination of small reductions to length, width and height, plus the weight and packaging thresholds, for the change that lowers each carrier’s published size surcharges the most with the least change to the box.

Short answer. Size surcharges switch on at fixed thresholds, so a one-inch change can remove a charge entirely. The optimizer tests up to 12 inches of reduction per side (about 2,000 cartons per carrier) and ranks results by saving, then by how little the box changes.

Calculating…

Caveats.
  • Only published size surcharges are compared (Additional Handling, Large Package / Oversize, over-limit and their demand versions). Base-rate effects of a lower DIM weight are extra and not shown.
  • A smaller carton only helps if the product still fits safely and the packing cost does not rise more than the saving.
  • No savings are promised; your contract discounts change the dollar amounts.
