A return trip such as Country A → China → Country A normally does not satisfy the third-country transit pattern. Hong Kong and Macao are treated as separate regions for route analysis, but verify your complete itinerary with the carrier and official source.

The four conditions
- Hold a passport from an eligible country.
- Enter through one of the designated ports.
- Hold a confirmed onward ticket to a third country or region.
- Remain within the permitted area and no longer than 240 hours.

Route examples
- London → Beijing → Tokyo: potentially valid if every other condition is met.
- Seoul → Shanghai → Hong Kong: potentially valid because the onward region differs.
- New York → Shanghai → New York: not a third-country transit pattern.

Before departure
- Ask the operating carrier to confirm that it will check you in under the transit policy.
- Carry the onward ticket, accommodation, passport and route details.
- Do not add a domestic segment that leaves the allowed transit area without confirming it is permitted.
