VAT Classes
VAT Classes are used to enhance the possible VATs at the countries list. By default there is only one standard VAT rate. If extra VAT classes exist, a extra column for each VAT class will be appended at th countries list. This enables you to define products with different VAT classes defined. E.g. Books, Magazines or Newspapers will often have a reduced VAT rate. See at Products how to set up the VAT rate.
