Why LCL quotes compare weight and volume
Less-than-container-load freight shares container space among multiple shippers. Many tariffs therefore use a weight-or-measure basis that compares cargo weight with cargo volume and charges on the higher rating unit defined by the quotation.
A common commercial convention is to compare one cubic meter with one metric ton, but the exact rule, minimum charge and included services depend on the forwarder, trade lane and tariff.
Work through both sides
Calculate the shipment CBM from packed dimensions and total gross weight from the packing list. If a quote states a specific W/M relationship, apply that relationship rather than assuming a universal rule.
Dense cargo can rate on weight while lightweight bulky cargo can rate on measure. Origin handling, destination charges, documentation and minimums may still be billed separately.
Ask for the rating basis in writing
Before comparing LCL offers, confirm the chargeable quantity, minimum billing unit, rounding method and whether pallets are included in the measured dimensions. Two rates per W/M can be misleading if the local charges and measurement rules differ.
Cargoivo helps with the physical volume calculation; the freight provider's current quotation remains the authority for the commercial charge.
A W/M worksheet without invented freight rates
Assume a fictional quote explicitly defines one rating unit as the greater of 1 m³ or 1,000 kg, with no minimum or rounding for this demonstration. Divide gross kilograms by 1,000, then compare that figure with the measured CBM. This convention must be written into the actual quotation before you use it.
The 2.4 m³ shipment switches from volume to weight when gross weight exceeds 2,400 kg under this assumed rule. If a different provider defines its unit differently, these numbers cannot be reused. Multiply by a genuine quoted rate only after confirming local charges, minimums and pallet measurement.
| Measured CBM | Gross kg | Weight units | Larger rating quantity |
|---|---|---|---|
| 2.4 | 800 | 0.8 | 2.4 |
| 2.4 | 2,400 | 2.4 | 2.4 |
| 2.4 | 2,800 | 2.8 | 2.8 |
