Manual on Statistics of International Trade in Services

An example of merchanting services 
Country A sells goods worth 100 units to a merchant in country C, who then resells the same goods to country B 
for 115 units. To demonstrate the situation, it is helpful to consider the recording of merchandise trade as well as 
that of services. 
If all transactions take place in one accounting period, then country A will show merchandise exports of 100 
units and country B will show merchandise imports of 115 units. Country C will record an export of 
merchanting 
services 
of 15 units. This asymmetry in the recommended treatment of such activity arises because of the 
pragmatic assumption that the importer in country B is not likely to know the value of the merchanting profit or 
loss realized by the merchant in country C.
If the goods are purchased by the merchant in country C in one accounting period and sold to country B in the 
next accounting period, then in the first accounting period country A would record the export of the goods and 
country C would record the import of the goods (which can be regarded as stocks held abroad), both valued at 100 
units. In the next accounting period when the goods are resold, country C would record a negative merchandise 
import equal to the value of the import in the previous period (100 units), country B would record the import of 
goods at 115 units, and country C would record exports of 
merchanting services
of 15 units.
