Can you carry duty-free alcohol with a layover in China?

Yes, you can, but there are some specifics regarding transporting alcohol during a layover:

• If you bought alcohol at a duty-free shop in the departure airport and are flying with one short layover in China (up to 24 hours) on the same airline with a single ticket, then duty-free alcohol can be carried in hand luggage without issues, if it is packed in a special sealed bag provided by the sellers at purchase. In this case, during the layover at the Chinese airport, you will go through standard aviation security screening, and alcohol sealed in special bags is allowed through without problems, personally verified. But if you conceal the bag, the alcohol will likely be confiscated.
• If you bought alcohol at a duty-free shop in the departure airport and are flying with two or more layovers, with one layover over 24 hours, or with one layover on different airlines, then you will have to go through the full visa-free transit procedure, including passport and customs control. In this case, your alcohol no longer qualifies as duty-free, and it must be packed in checked baggage, not in hand luggage. Additionally, you will effectively be importing it into China and then exporting it, i.e., moving it through customs, where restrictions apply of no more than 1.5 liters of strong alcohol per person, so excess may be confiscated.
