Customs Groups 
A customs group is a group of freight unit (FU) items for which a customs declaration is required. At least one customs group must be created in order to perform a customs process.
The system creates customs groups according to the grouping strategy that is assigned to the customs activity. The strategy groups the items according to specific criteria, such as the consignee or the goods seller. Depending on the criteria, more than one customs group (and therefore more than one customs declaration) may be created for a load that is to be transported together.
You can use the following standard grouping strategies:
EXP_CONS
