Tariff Quota - are a form of EC preference under which limited amounts of specified goods may be admitted to free circulation at reduced or nil rates of duty and/or CAP levy within a given period. The limit may be expressed in units of weight, volume, quantity or value. Once a quota has been exhausted, the commodity may still be imported, but duty or levy must be charged at the non-quota rate.
