Can a power bank without CCC certification be confiscated when transiting through China on a flight to Cam Ranh (Nha Trang)?

Chinese airport staff may repeat power-bank checks at the boarding gate, so a missing CCC mark can still be discovered after the main security screening.

On the Moscow–Beijing–Guangzhou–Nha Trang route, travelers reported that three non-CCC power banks were taken in Beijing because the next flight was domestic within China. Passengers flying directly from Beijing onward to a third country were reportedly allowed through without the same issue.

Recent traveler reports say a power bank needs a CCC mark for flights through China. Without it, security may confiscate it; some travelers specifically noted this is more common on domestic Chinese flight segments.

If you are flying direct to Nha Trang, this China power-bank issue usually does not apply. The problem mainly comes up on itineraries that include a transfer in China.

There is a specific report from a Cam Ranh trip with a stop in Wuhan: transit passengers had several power banks without CCC marking taken at security. That suggests checks are actively enforced, not just theoretical.

For China transfers on a single through-ticket with the same airline, travelers consider about 2.5 to 3 hours a workable connection time. If the first flight is delayed, the airline may escort passengers through priority control or rebook them on the next flight.

With a short connection in China, the key thing is making sure you are checked in for the next segment. Travelers say passport and customs lines can be long, but staff may let passengers move ahead if the onward flight is about to depart.
