Barriers to trade are restrictions that countries impose to control the amount of foreign goods and services entering their markets. These barriers can take various forms, including tariffs, which are taxes on imports, and quotas, which limit the quantity of a specific product that can be imported. Such measures are often used to protect domestic industries from foreign competition. Non-tariff barriers, such as strict regulations and standards, can also hinder trade. For example, health and safety regulations may require imported goods to meet specific criteria, making it difficult for foreign producers to enter the market. Overall, these barriers can impact international trade relationships and economic growth.
