Basic Air Parcel Logistics:
Your shipping cost is the base rate + Fuel Surcharges
Each package’s cost is based on either actual weight or dimensional weight (dim weight or volume weight), whichever is greater. Always round it up to the next number.
Volume / Dimension weight formula:
L X W X H (inches) / 139 = DW in LBS
L X W X H (cm) / 5000 = DW in KGS
For example, if your package is 20.5 lbs actual weight, and dimensions are 10.2 in x 8.5 in x 5.6 in. Round up all numbers. Actual Weight (AW) = 21 lb, Dimensional Weight = 11 in x 9 in x 6 / 139 = 4.2 lb, which need to round up once again so Dimensional Weight (DW) = 5 lb
AW of 21 lb > DW of 5 lb. Price will determined by AW
If there are multiple shipments, each shipments need to compare AW vs DW and sum whichever is higher to all shipments.
Actual Weight = Gross Weight
Dimensional Weight = Volume Weight
