Estimate packing groups and chargeable weight from explicit carton and carrier divisor assumptions.
Ten cartons that each weigh 8 kg physically may still be billed at a higher weight if their dimensions produce a larger dimensional weight under the carrier divisor. The module compares the two values per carton and uses the larger as the planning chargeable weight.
The divisor is editable because carriers and services use different rules. Copy it from the actual quote or tariff, and remember that some services apply additional rounding or oversized-package rules after the basic calculation.
Shipment grouping estimates how many dispatches are needed when only a fixed number of cartons travel together. It does not decide palletization, cushioning, edge protection or hazardous-material requirements.
Dimensional-weight formulas can make a light, bulky shipment price as if it were heavier.
The divisor and rounding method must be taken from the chosen carrier or provider.
The calculator covers geometry and weight, not cushioning, moisture, edge protection or stacking suitability.
