What kind of barriers do tariff barriers represent?

Tariff barriers represent trade barriers that specifically rely on tariffs, which are taxes imposed on imported goods, to discourage imports. The purpose of imposing tariffs is to increase the cost of foreign products, making them less competitive against domestic products in the local market. This can protect local industries from foreign competition by making imported goods more expensive for consumers. As a result, tariff barriers directly affect the flow of trade by increasing the price of imported goods, thereby potentially reducing the volume of imports. They play a significant role in trade policy, as countries may use tariffs strategically to support their economic interests and protect local businesses from international competition. Other choices do not accurately represent the nature and function of tariff barriers, focusing instead on different aspects of trade interactions.
