How to determine the class of cargo

The question of how to determine the class of cargo during transportation arises when it is necessary to establish a tariff group and calculate the amount of payments.
There are four classes of cargo, which are determined by the use of the vehicle's carrying capacity.
If the load has a large specific gravity, it makes full use of the carrying capacity of the vehicle. Light, complex-shaped goods do not allow filling the body so that the mass of the transported goods approaches its carrying capacity. Therefore, the transportation fee is charged depending on the class, taking into account the density, as well as the method of packaging, since the bulk container reduces the amount of cargo that can be transported.
