AIR FREIGHT VOLUMETRIC CALCULATIONS
All freight transportation modes are governed by weight and cubic measurement factors, whereby the Carrier will charge on Actual Weight or Volumetric, whichever is deemed to be the greater.
The IATA / Airline Cubic Allowance Factor for Air Freight Shipments is
1 Kilo = 6,000 Cubic Centimetres.
The illustration below shows you how to calculate the Volumetric Chargeable Weight as follows:
- Let’s assume the actual gross weight of this carton is 14 Kilos.
- The carton measures 30 × 45 × 65cms which is 87750 Cubic Centimetres.
- Divide this figure by the IATA/Airline Cubic Allowance Factor of 6000 Cubic Centimetres = 14.625 Kilos.
- In this instance the Air Freight charge will be calculated on 15 Kilos volumetric, rather than the 14 kilos actual weight.
CALCULATING CUBIC MEASUREMENT FOR ROAD & OCEAN FREIGHT
The Standard (RHA-Road Haulage Allowance) Factor for Road Freight is 3 Cubic Metres per 1,000 Kilos, whereas the Standard Maritime Allowance Factor for Ocean LCL Groupage Freight is 1 Cubic Metre per 1,000 Kilos.
This illustration below shows you how to calculate the Volumetric Chargeable Weight as follows:
Let’s assume the actual Gross Weight Skid is 150 Kilos, this Skid measures 1 Metre X 1.2 Metres X 1.5 Metres, which is 1.8 Cubic Metres.
ROAD FREIGHT CALCULATION
(Based on the RHA standard)
In this instance the Freight Charges for Road Freight are calculated as
1.8 Cubic Metres X 333 = 599.4 Kilos, so the Chargeable Weight is based on 599 Kilos.
(Based on the IMC standard)
In this instance the Freight Charges for Ocean Freight are calculated as 1.8 Cubic Metres X 1,000 = 1,800 Kgs, so the Chargeable Weight is based on 1,800 Kgs.
