compound tariff的意思|示意

Compound tariff is an import tariff system in which a combination of tariffs and charges is employed, including ad-valorem duties, specific duties, and additional duties. Ad-valorem duties are calculated as a percentage of the value of the imported goods. Specific duties are levied according to the quantity of the goods imported. Additional duties are charged on the basis of a country's foreign exchange regulations, such as the exchange rate, or on the basis of particular economic policies, such as export subsidies.

Compound tariff is advantageous in that it can effectively protect domestic production, endow the tariff system with flexibility, and add revenue to cover some of the government's expenses. For example, after the United States employed a compound tariff system, its revenue from tariffs rose from 9.7% of the total imports' value in 1969 to 18.5% in 1980.

However, compound tariff is complicated and difficult to implement. It cannot easily be used as an economic policy tool because of its complexity as well as its heavy reliance on exchange rate fluctuations. Moreover, due to the high reliance on exchange rate fluctuations, it is difficult to maintain the effectiveness of the system.

In conclusion, compound tariff is a complex system that has both its advantages and disadvantages. It can be used to effectively protect domestic production and to raise revenue for the government, but its complexity and its reliance on exchange rate fluctuations can make it difficult to use as an economic policy tool.
