Final answer:
An example of a trade barrier is a tariff, which is a tax on imported goods. Another example is a nontariff barrier, which includes rules, regulations, inspections, and paperwork that make importing more costly or difficult.
Step-by-step explanation:
Tariffs increase the cost of imported products, making them more expensive for consumers and less competitive compared to domestically produced goods. This discourages imports and protects domestic industries from foreign competition.
Another example of a trade barrier is a nontariff barrier. This includes rules, regulations, inspections, and paperwork that can make it more costly or difficult to import products. For instance, a country may impose safety standards that limit imports, or have rules-of-origin regulations that require the last substantial change in a product to occur in their own country.
These trade barriers can be used by governments to encourage or discourage trade based on their economic and political goals.
