Explanation : A quota is a quantitative restriction on
imports. Quotas limit the amount of a product
that can be imported into a country over a
specified period of time, such as a calendar
year. Quotas are a form of non-tariff barrier
(NTB), i.e., they are not tariffs but have the
same impact in terms of restricting free trade
and protecting domestic industries. Quotas
restrict the availability of the foreign product
in the domestic market and, therefore, provide
an advantage to local producers. There are
various forms of quotas.
