Same-country loop
If the route is essentially country A → China → country A, the third-country or third-region rule is usually not satisfied.
Transit mode
Does your route look eligible for China's current 240-hour transit policy?
Use this page if your plan is not a simple visit. It screens nationality coverage, the third-country or third-region rule, the raw time window, and the port-area confirmations that usually trip travelers up.
240-hour transit checker
This tool works best when you already know your origin, your onward destination after China, and your rough time window inside mainland China.
Pick a transit region to see the most useful reminder for your stay area.
What breaks eligibility
Most failed transit plans go wrong in one of four places.
No onward proof
You need confirmed onward arrangements, not just a plan in your head.
Wrong port or wrong area
The nationality and route may fit, but the entry point and stay area still need to align with the designated geography.
Unsupported activity
Tourism, business, family visits, and exchange visits fit the current framework used here. Work, study, and news reporting do not.
Third-country and third-region reminder
Hong Kong SAR, Macao SAR, and the Taiwan region count as valid third regions in the public transit interpretation used here. That is why many travelers can structure a route like country A → mainland China → Hong Kong SAR.
Time rule reminder
The official interpretation says the stay is measured from 00:00 on the day after entry. This checker still asks for your raw stay window because that is the easiest first-pass filter when comparing itineraries.
