What are trade tariffs?

Trade tariffs are defined as taxes imposed on imported goods. They are a tool used by governments to regulate international trade, often intended to protect domestic industries from foreign competition by making imported goods more expensive. By increasing the cost of these goods, tariffs can encourage consumers to purchase locally-produced products instead. This economic strategy is also utilized to generate revenue for the government.

The other options revolve around different aspects of trade and economic policy. Subsidies offered to domestic industries are financial supports to encourage local production rather than being a form of taxation on imports. Regulations for international labor standards pertain to labor rights and conditions, which are separate from trade tariffs that specifically relate to the taxation of goods. Fees for shipping and customs inspections are charges associated with the logistics and clearance of goods at borders but do not represent a tax on the goods themselves like tariffs do. Thus, the distinctive feature of tariffs lies in their function as taxes that directly affect the price of imported goods, making answer B the correct response.
