LCL shipping cost is charging by Volume in Cubic Meter(CBM). But weight will be also taken into account for heavy cargo with small volume.
Interpretation
Volume matters more than weight
The chargeable unit by lcl shipping is volume ( per CBM ), MIN charge 1CBM
For heavy cargo, then the chargable unit is per ton. Normally conversion ratio is 1 CBM = 1000 kg
For instance
For a 5 CBM, 600 KG cargo from Shanghai to Hamburg,
When the quote is USD 50 / CBM, then total LCL shipping cost is 50 x 5 = USD 250.
However, if cargo is 5 CBM, 6000 KG, then LCL shipping cost is 50 x 6 = USD 300.
