Tariffs and trade barriers limit or prevent some types of trade or impede trade with other countries. These often protectionist measures in the long term may increase the commodities or consumer goods with which the country wants to interact, as it creates a situation of estrangement between the two countries that will correlate.
A tariff is a tax on imports that is meant to help consumers and sometime protext national security. In general, over long periods of time, tariffs can lead to more domestic jobs.
