Answer: Import restrictions
Explanation: Import restrictions are methods used to control the types, quantity and value of goods being imported into a country from other countries.
There are various types of import restrictions and they are:
1. Import duties: import duties are tariffs or taxes imposed on imported goods to make them more expensive thereby discouraging the purchase and use of imported goods.
2. Import quota: this is a restriction on the volume of imported goods that would be allowed into the country at a particular period of time or from a particular country.
3. Currency restrictions: this is used to restrict the amount of foreign currency used in the settlement of imported goods.
4. Prevention of the entry of illegal or harmful items into the country.
