Answer 2

Tariffs are customs duties, consisting of export duties and import duties. These are indirect taxes imposed on goods exported or imported in a given country.

Import duties can be seen as a form of protectionism: protecting the own market against competing imports from other countries. Export duties often have a political character or importance. Generally, tariffs are set on certain products with the objective of discouraging their importation, thus promoting national production.
