A quota that is determined on the basis of the applicable tariff rate applied to imports. A predetermined amount of a good is allowed to enter at a reduced or zero tariff rate. After the quota has been filled, all subsequent shipments of that good during a specific period of time, such as a calendar year, are assessed a higher import tariff, usually the normal most-favoured-nation tariff.
the quantity of merchandise that can be imported at a reduced tariff per unit time. Any quantity can be imported, but overages are assessed at a higher duty.
