There is no limit on the amount of cash carried by foreign airlines, but the amount of cash carried exceeds the prescribed amount and needs to be declared to the customs. According to the customs regulations, the following inbound passengers should declare to the customs, and submit the declaration documents to the customs for entry formalities: (1) Bring the articles in Category II, III and IV of the Classification Table for Inbound and Outbound Luggage of Passengers that need to be taxed or exempted by the customs (excluding duty-free and limited tobacco and alcohol); (2) Non-resident passengers and resident passengers with re-entry visas carry cameras, portable tape recorders, small cameras, portable video cameras and portable word processors for their own use; (three) carrying more than 6000 yuan in cash, or more than 50 grams of gold, silver and its products; (4) Non-resident passengers carry foreign currency cash equivalent to more than 5,000 US dollars; (5) Resident passengers carry foreign currency cash equivalent to 65,438 US dollars+0,000 yuan or more; (6) Carrying goods, samples and articles other than passengers' personal luggage; (seven) carrying animals, plants, plant products and other articles that should go through the formalities of inspection and release according to the quarantine regulations of China.
