Calculation of LCL freight
The calculation of LCL’s freight mainly adopts the “W/M” mode. Cargo transportation costs are divided into weight tons (W) and dimension tons (M). The unit of measurement “W/M” means the unit of measurement is tons, the unit weight is 1000 kilograms, the unit is cubic meters, the unit of measurement is “W/M”. Theoretically, the default unit rate is generally fixed. When solving this problem, more consideration is given to the comparison of single-variable freight rates.
However, in actual business, the LCL rates provided by different freight forwarders often vary based on weight tons and size tons. In this case, dual variables need to be considered and calculated based on a combination of different rates and freight tons. Compare.
