·The entry regulations in China
 
What you should do when entering China is to fill in the Entry Registration Cards and have your passport and visa checked, including other procedures such as a quarantine check and frontier inspection. All your goods, luggage and packages should also be checked. People with VD, leprosy and infectious pulmonary are not allowed to entering China. Dangerous, harmful or toxic articles prescribed by Chinese law are prohibited into China and you must declare them to the Frontier Inspection Station. Usually the airline/ship will give each passenger an entry card and a customs declaration form to fill out prior to arrival.

·The procedures to declare at customs

For the convenience of inbound or outbound visitors, on February 1st, 2008, China made simplification of the custom declaration procedures. People who have nothing to declare can pass through the green channel directly. And people who carry articles that need to be declared must fill out a Chinese custom declaration form and pass through the red channel. However, for children under 16 and accompanied by their parents, there is no obligation to fill in the declaration form themselves. For those who hold diplomatic or courtesy visas should present the effective certificates or documents to get more efficient services from China Customs. When departing from China, travelers can choose either to complete the same declaration form listed with relevant items or to fill out a new one.
