Interparcel will take into consideration the cubic weight or dimensional weight of your shipments.
Whichever value is the greatest, the dead weight or the cubic/dimensional weight will be used to determine the shipping cost.
The container/ custom box dimensions are
Length 125 x Width 125 x Height 125=1953125.00 ÷ 4000 = 48.828125
this will be rounded off to 49kg.
The dead weight was 36 KG
Interparcel did not accept this size container, no shipping rate was provided.
The cubic/dimensional weight calculation is:
L x W x H / 5000
L x W x H / 4000
