## Below are given guidelines for calculating the freight cost per unit or taxable weight.

Each mode of transport, land,sea, airplane, or rail, partial loads (containers, trucks or wagons) use a different system for calculating the freight cost per unit, the base on which the shipping cost is calculated.

### Maritime Freight

W/M rate: the rate usually applies to the weight W calculated in metric tons (1,000 kg) or to the volume M (measurement), calculated in cubic metres (CBM), whichever is greater, in favour of the shipping company.

W rate: in some cases it is calculated only on weight W.

ML rate: a rate per linear metre is sometimes applied when transporting vehicles on RORO ships.

### Air Freight

This rates is calculated on the weight (kg), with a maximum weight/measurement ratio of 1,000 kg: 6 CBM; if the volume of the goods exceeds this ratio (1:6) the freight cost for the unit is obtained by dividing the volume by 6.

### Land Freight

This rates is calculated in 100s of kg, with a maximum weight/measurement ratio of 1000 kg: 3 CBM; if the volume of the goods exceeds this ratio (1:3) the freight cost for the unit is obtained by dividing the volume by 3.

### Land Freight

This rate is calculated on weight, but it varies depending on the characteristics of the goods.
