Key takeaways
- Chargeable weight is generally the higher of actual and volumetric weight.
- A small change in carton dimensions can materially change the air-freight charge.
- The applicable divisor and rounding rules depend on the service.
Scope note: This article provides general planning guidance. Carrier acceptance, customs, compliance, price and timing must be confirmed for the actual shipment.
Actual and volumetric weight
Actual weight is measured on the scale. Volumetric weight converts the space occupied by the packed cargo into a weight equivalent. The carrier normally charges whichever is higher.
- Measure length, width and height at the widest packed points.
- Use the carrier or service divisor stated for the quotation.
- Allow for pallet or overpack dimensions.
Why packing changes the rate
Protective material, pallets and non-stackable space can increase the chargeable profile even when the product itself is light.
- Request dimensions after export packing.
- Compare safe packing improvements, not unsafe compression.
- Separate oversized pieces for acceptance review.
What else affects the air quote
Chargeable weight is important but not the only variable. Routing, capacity, commodity, security, terminal charges and delivery scope also matter.
- Confirm direct or connecting routing.
- Declare batteries and controlled goods.
- Compare airport and door-delivery scopes consistently.
