Billing Unit

In shipping, a billing unit refers to a unit of measurement used to determine the charges or fees associated with a particular shipment. The billing unit is typically used by carriers, freight forwarders, and other service providers to calculate the cost of shipping goods from one location to another. 

The billing unit may vary depending on the mode of transportation and the specific services provided. For example, in air freight shipping, the billing unit is typically based on the weight of the shipment, with charges assessed per kilogram or pound of weight. In ocean freight shipping, the billing unit may be based on the volume of the shipment, with charges assessed per cubic meter or cubic foot of space occupied by the goods.
