What is an example of a non-tariff barrier?

An import quota is a specific limit on the quantity or value of goods that can be imported into a country within a given time frame. This type of restriction is designed to protect domestic industries from foreign competition by controlling the supply of imported products in the market. Unlike tariffs, which impose fees on imports, non-tariff barriers like import quotas do not directly increase the cost of goods but rather limit the volume of imports, thereby affecting market dynamics and prices indirectly.

This practice allows governments to regulate the availability of foreign goods, which can favor local producers, maintain a balance of trade, and support specific sectors that may otherwise struggle against international competition. It's important to note that while other options listed, such as duties and taxes, are tools used in trade regulation, they are classified as tariff barriers since they involve financial charges directly levied on imports or exports.
