How a sale is treated for tax, from the UN/CEFACT tax category codes (UNCL 5305) as Peppol PINT A-NZ allows them: standard rated, zero rated, exempt, free export, or outside the scope of tax. A listing takes its listing type's category unless an operator overrides it. Which treatment and which listing type take which category in each country is for an accountant.
The tax category of a listing, an order line or a tax line. A listing takes its listing type's category unless an operator overrides it, and each order line freezes the category it sold under.
