A primary characteristic of tariff barriers is that they are taxes imposed on imported goods. This means that when goods cross international borders, these taxes are added to their cost. Tariffs are designed to increase the price of foreign products in order to protect domestic industries from foreign competition. By making imported goods more expensive, tariffs can encourage consumers to purchase domestically produced items.

The imposition of tariffs affects trade flows, making imported goods less competitive in terms of pricing. This is a fundamental function of tariffs and highlights their role in trade regulation and economic policy. Additionally, while non-tariff barriers may encompass various regulations and quotas that can also restrict trade, the very essence of a tariff barrier is its monetary charge on imports.

Other options, while relevant to trade policy, do not accurately capture the defining trait of tariff barriers. For instance, visibility is more of a characteristic associated with non-tariff barriers, and tariffs do not generally promote free trade agreements; in fact, they can conflict with the principles of such agreements. Lastly, customs authorities are the entities responsible for enforcing tariff regulations, making the idea that they are not enforced by customs incorrect.
