## Description

Add classifications to an item.
            
A classification is the code for a product in a particular tax system. Classifications enable an item to be used in multiple tax systems which may have different tax rates for a product.
            
When an item is used in a transaction, the applicable classification will be used to determine the appropriate tax rate.
            
An item may only have one classification per tax system.
