My friend from Argentina flew into Shanghai Pudong. He thought his 240-hour transit clock started when he got his passport stamped at immigration.
He was wrong.
The rule:
The 240-hour countdown starts from the scheduled landing time of your flight, not from when you clear immigration.
His flight landed at 11:30 PM. By the time he cleared immigration, got his bags, and reached his hotel, it was 2:00 AM. He had already lost 2.5 hours.
He found this out on Day 9 when he tried to calculate his departure time.
How the 240-hour clock actually works:
Start: The scheduled arrival time of your inbound flight End: 240 hours (10 days) from that exact moment Example: Land at 11:30 PM on June 1 → Must depart by 11:30 PM on June 11
Important:
• The clock starts even if your flight is delayed. If your flight was scheduled for 11:30 PM but actually landed at 1:00 AM, the clock still started at 11:30 PM.
• The clock does NOT pause if you leave China temporarily. Once it starts, it runs continuously.
• Overstaying by even 1 hour can result in fines (¥500/day), deportation, and a ban from re-entering.
How to track it:
• Write down your exact landing time
• Set a phone alarm for 230 hours after landing (gives you a 10-hour buffer)
• If you're cutting it close, book an earlier departure flight
My Argentine friend's lesson:
"I thought I had 10 full days. I actually had 9 days and 21 hours. It's a small difference, but if you're planning a tight itinerary, every hour matters."
