Can you bring duty-free alcohol through China with a long layover and city exit?

With a 24-hour layover in China that includes exiting the airport, duty-free alcohol bought in Nha Trang will most likely be confiscated when re-entering the Chinese airport. This is a known issue worth considering before purchase.

China enforces strict rules on re-entering the departure zone after a city exit. Duty-free liquids purchased abroad may be confiscated at security, especially without original sealed packaging and a receipt showing the purchase airport.

Fresh fruit from Vietnam can also cause issues during a China transit — Chinese customs strictly controls plant-based products. Check the specific transit airport's rules before traveling.

On Aeroflot flights from Nha Trang to Moscow, bringing both a backpack and a fruit basket as carry-on may cause issues at check-in, as airlines often allow only one carry-on item per passenger.
