How do tariffs as trade barriers affect globalization and the implementation of trade policies in a country?

Tariffs are taxes that a government places on imported goods, and they can significantly impact globalization and trade policies. When a country imposes tariffs, it makes foreign products more expensive, which can lead to reduced imports. This can protect local industries but may also lead to higher prices for consumers and less variety in products available. For example, if a country places a high tariff on imported cars, people might buy more local cars, but they could end up paying more for them than they would for the imported ones. Overall, while tariffs can help local businesses, they can also slow down the flow of goods between countries and complicate international trade agreements.
