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.

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

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