There are two kinds of rates. One are import duty rates and the other are export duty rates. The import rates fall into two categories: general tariff rates and preferential tariff rates. The general tariff rates apply to goods imported from countries with which China has not concluded most-favoured-nation trade agreements, while the preferential tariff rates have.
Most of the goods are subject to duties on amount. Yet a small number of them are subject to duties on quantity, compound, or sliding basis.
