Calculating size and weight

When the shipment is too large?

Calculating volumetric weight

Large, lightweight packages are charged at their volumetric weight for the space they occupy, rather than their actual physical weight. To determine volumetric weight, first calculate the volume of your package and then multiply this figure by the relevant conversion factor.

Volumetric Calculation

How to calculate domestic volumetric (cubic) weight

For TNT Domestic Express services the standard volumetric calculation is based on 250 kg's per cubic metre. To calculate the volumetric weight for these types of shipments (chargeable weight) multiply the Length (L) x Width (W) x Height (H) in centimetres and divide by 4,000.
 

For Example.

 

50 (L) x 30 (W) x 40 (H) = 60,000 divided by 4,000 equals 15 kg volumetric weight.

Please note that TNT charges the higher of either the dead (actual) or volumetric weight.


How to calculate international volumetric (cubic) weight

For TNT Economy Express services - effective 9 June 2010 (including Economy IDE) and TNT Express Services (including Express Documents, Express Parcels, Express Freight and Express IDE) the international calculation is based on 200 kg's per cubic metre. To calculate the volumetric weight for these types of shipments (chargeable weight) multiply the Length (L) x Width (W) x Height (H) in centimetres and divide by 5,000.
 

For Example.

50 (L) x 30 (W) x 40 (H) = 60,000 divided by 5,000 equals 12 kg volumetric weight.

Please note that TNT charges the higher of either the dead (actual) or volumetric weight.
