Understanding Chargeable Weight in Air Freight
In domestic air freight, the chargeable weight determines the cost of shipping a package. Airlines and freight forwarders compare the actual weight with the volumetric (dimensional) weight of cargo and charge based on whichever is greater.
Accurately calculating chargeable weight ensures fair pricing, optimizes aircraft load, and avoids unexpected freight costs for businesses.
Actual Weight vs. Volumetric Weight
Actual weight refers to the physical mass of the shipment measured in kilograms. Volumetric weight accounts for the space a package occupies in the aircraft. Airlines use a standard conversion formula: Volumetric Weight (kg) = Length (cm) × Width (cm) × Height (cm) ÷ 6000.
Example: A package with dimensions 100cm × 80cm × 25cm weighs 50 kg physically, but volumetrically: 100 × 80 × 25 ÷ 6000 = 33.33 kg. Chargeable weight = 50 kg (the higher of the two).
Why Chargeable Weight Matters
Chargeable weight affects the following aspects of domestic air freight:
- Cost Management: Helps businesses estimate shipping expenses accurately.
- Aircraft Load Planning: Ensures safe weight distribution and efficient use of cargo space.
- Compliance: Aligns with CASA regulations on cargo weight limits.
Tips to Optimize Chargeable Weight
- Use Proper Packaging: Minimize empty space while protecting goods.
- Consolidate Shipments: Combine multiple packages to reduce volumetric impact.
- Measure Accurately: Ensure precise dimensions and weight reporting to avoid overcharges.
- Choose Efficient Carriers: Some providers offer weight optimization strategies using advanced logistics software.
