Short answer: Start with the part of your trip immediately before and after Mainland China.

Think of it as:

A → Mainland China → C

For the 240-hour visa-free transit policy, A and C need to be different countries or regions.

But that is only the first test. Your passport, onward travel, entry port, departure plan, and where you plan to travel inside China also need to fit the current rules.

Can your route use 240-hour visa-free transit?

1 — Passport

Is your passport currently eligible?

2 — Route

A → Mainland China → C

Are A and C different countries or regions?

3 — Onward travel

Do you have confirmed onward travel to C?

4 — Entry + departure

Does your planned entry port — and the way you plan to continue to C — fit the current rules?

5 — Travel area

Is every place you plan to visit inside the currently permitted area?

Pass all five → Your itinerary appears to fit the policy.

Final eligibility is checked by immigration.

The current policy covers eligible travelers from 57 countries, 65 designated ports and permitted areas across 24 provincial-level regions.

These details can change. Rather than relying on an old list copied into a travel article, check the current official policy for your actual trip.

Check the current official rules: National Immigration Administration — 240-Hour Visa-Free Transit Policy

These checks help you work out whether your itinerary appears to fit the policy. They do not guarantee admission. Your documents and eligibility are still checked by immigration when you enter China.

Don’t judge it from your whole vacation

This is one of the easiest ways to get the 240-hour policy wrong.

What matters is not necessarily where your entire holiday starts or where you eventually fly home.

Look at the journey immediately around Mainland China.

For example:

Works

London → Shanghai → Tokyo

UK → Mainland China → Japan

A ≠ C

Doesn’t work

New York → Shanghai → Los Angeles

USA → Mainland China → USA

A = C

Changing cities in the same country does not turn the trip into transit to a third country or region.

Layovers matter too.

Imagine your full trip looks like this:

USA → Hong Kong → Beijing → Hong Kong → Nepal

It may look like you’re traveling from the USA to Nepal via China.

But immediately around Mainland China, the route is:

Hong Kong → Mainland China → Hong Kong

A and C are the same region.

That is the route you need to judge.

Hong Kong and Macao can change the answer

For this policy, a third country or region can matter on either side of Mainland China.

So these two trips are not the same:

Hong Kong → Mainland China → Japan

and

Hong Kong → Mainland China → Hong Kong

In the first, the regions immediately before and after Mainland China are different.

In the second, they are the same.

The same route logic is why you should pay attention to connections and layovers rather than only looking at the first and last cities on your booking.

Your route works. Now check the actual ports and places

Passing the A → Mainland China → C test does not automatically mean your itinerary qualifies.

Your entry port must be eligible, your onward journey must fit the policy, and your travel inside China must stay within the currently permitted areas.

The list of eligible ports can change. West Kowloon Station in Hong Kong, for example, was added to the 240-hour policy in November 2025. So check the current official port list rather than relying on older travel advice.

Do not try to memorize a static list of 65 ports.

Check the port you actually plan to use against the current official rules.

The same applies to where you travel inside China.

Crossing from one province to another is not automatically a problem. The policy allows travel across permitted areas in multiple provincial-level regions.

But being inside one of the covered provinces does not always mean that every city in that province is permitted.

Check every place on your itinerary, not just the province name.

For the current permitted ports and travel areas, use the National Immigration Administration’s current policy page.

You need confirmed onward travel

A route that works on paper is not enough if you have not arranged your onward journey.

The current policy requires eligible travelers to have confirmed onward travel to the third country or region within the permitted period.

That is why:

A → Mainland China → C

is not just an itinerary idea. You need to be able to show the onward part of the trip.

If you plan to leave by train, ferry or a land crossing rather than a normal international flight, check the current rules for the exact port and journey you plan to use rather than assuming that an old answer online still applies.

How are the 240 hours counted?

The 240-hour period starts at 00:00 on the day after you enter China.

So if you arrive on Monday afternoon, the 240-hour clock begins at 00:00 on Tuesday.

That can give you more usable time than simply counting ten 24-hour periods from the moment your flight lands.

But there is a difference between using the available time and building an itinerary with almost no margin.

Using most of the 240 hours can work — just understand that it leaves less room for delays or mistakes.

If your departure is very close to the end of the permitted period, that is a trade-off you should make deliberately rather than accidentally.

If your passport already qualifies for ordinary visa-free entry to China, you may not need to rely on the 240-hour transit policy at all.

Using the 240-hour policy for your China itinerary?

A route can look simple on a map and still depend on the exact connections, ports and places you plan to visit.
