What are tariff barriers primarily used for?

Tariff barriers are primarily used for the protection of domestic markets. This is achieved by imposing taxes on imported goods, which raises their prices compared to locally produced products. By making foreign goods more expensive, tariffs encourage consumers to buy domestically produced items, thus helping local businesses thrive and maintaining market share against international competition. This protectionist measure is particularly beneficial in industries that may struggle to compete with lower-cost imports.

While other factors may influence a country's trade policies, the primary aim of tariff barriers is to safeguard domestic economies. They do not directly regulate foreign investments, promote exports, or directly support local industries outside of providing a favorable pricing environment, but they do create a competitive edge for domestic products in the market.
