A per unit tax, or specific tax, is a tax that is defined as a fixed amount for each unit of a good or service sold, such as cents per kilogram. It is thus proportional to the particular quantity of a product sold, regardless of its price. Excise taxes, for instance, fall into this tax category. By contrast, an ad valorem tax is a charge based on a fixed percentage of the product value. Per unit taxes have administrative advantages when it is easy to measure quantities of the product or service being sold.

Per unit tax in the context of Indirect tax
An indirect tax (such as a sales tax, per unit tax, value-added tax (VAT), excise tax, consumption tax, or tariff) is a tax that is levied upon goods and services before they reach the customer who ultimately pays the indirect tax as a part of market price of the good or service purchased. Alternatively, if the entity who pays taxes to the tax collecting authority does not suffer a corresponding reduction in income, i.e., the effect and tax incidence are not on the same entity meaning that tax can be shifted or passed on, then the tax is indirect.
An indirect tax is collected by an intermediary (such as a retail store) from the person (such as the consumer) who pays the tax included in the price of a purchased good. The intermediary later files a tax return and forwards the tax proceeds to government with the return. In this sense, the term indirect tax is contrasted with a direct tax, which is collected directly by government from the persons (legal or natural) on whom it is imposed. Some commentators have argued that "a direct tax is one that cannot be charged by the taxpayer to someone else, whereas an indirect tax can be."
