Taxes on products (D.21) are taxes that are payable per unit of some good or
service produced or transacted. The tax may be a specific amount of money per
unit of quantity of a good or service, or it may be calculated ad valorem as a specified percentage of the price per unit or value of the goods and
services produced or transacted. As a general principle, taxes in fact assessed on
a product, irrespective of which institutional unit pays the tax, are to be
included in taxes on products, unless specifically included in another heading.
