Answer: government taxes on products or services entering a country that primarily serve to raise prices on imports.

Explanation:

Tariffs are known to be taxes which the government of a particular country charges on goods and services which are imported into the country from other countries. It is a form of trade protection which the government uses in protecting local companies. Thus, the government imposes taxes on imported goods in order to make the prices of the goods high so that citizens can buy local or domestic goods and as a result encourage domestic companies to produce more of the local goods.
