How is dimensional (DIM) weight calculated for single packages?

  1. Compare measured and dimensional weight.
  2. The greater of the two is used for billing.
  3. The dimension parametar for the aircraft is 5000, for the truck 4000.
Example 1:
Measured weight: 15 kg
Dimensions L = 60; W = 45; H = 45 cm
DIM weight = 24.5 kg
DIM weight is billed
Example 2:
Measured weight: 5 kg
Dimensions L = 45; W = 20; H = 25 cm
DIM weight = 4.5 kg
Measured weight is billed

Weight is rounded up to the nearest upper limit, to 1/2kg for weight up to 10kg, to a whole if the weight is more then 10kg.

Example 3:
DIM weight = 4.1 kg
Billed as 4.5 kg
Example 4:
DIM weight = 25.3 kg
Billed as 26 kg

How is dimensional (DIM) weight calculated for multi-package shipments (MPS)?

When calculating DIM weight for IPF MPS shipments, determine the total measured weight, and compare it to the DIM and IPF DIM weights.

Example 5:
Number of packages: 3
Package 1: 14 kg |  L = 60 * W = 45 * H = 45 = 24.3 kg
Package 2: 3 kg |  L = 10 * W = 10 * H = 10 = 0.2 kg
Package 3: 40 kg |  L = 100 * W = 70 * H = 40 = 56.0 kg
Measured weight = 57 kg
DIM weight = 80.5 kg

IPF - International Priority Freight Service

Service is used for shipments where the volumetric weight of any box exceeds 68kg.

  • L = 70cm
  • H = 75cm
  • W = 80cm
  • DIM weight = 84.0kg

The shipment qualifies for IPF service because the volumetric weight is greater than 68kg.

How is volumetric (DIM) weight calculated for multi-package shipments (MPS) in the IPF service?

When calculating DIM weight for IPF MPS shipments, determine the total measured weight and compare it with the DIM and IPF DIM weights.

Example 6:
Number of packages: 3
Package 1: 100 kg |  80 * 70 * 75 = 84.0 | 68 kg
Package 2: 50 kg |  50 * 50 * 50 = 25.0 | 68 kg
Package 3: 40 kg |  40 * 40 * 40 = 12.8 | 68 kg
Measured weight = 190 kg
DIM = 121.8 kg
IPF DIM = 204 kg

The highest result for volumetric weight is used as a condition for the entire shipment to qualify for IPF service.
