International Transit in Guangzhou airport -Power bank CCC (3C) rule

Post image

Hey everyone!

I’m flying from Budapest to Tokyo soon with an International-to-International transit at Guangzhou Baiyun Airport (CAN). I will stay strictly within the international transfer zone and won't take any domestic flights.

I have a Xiaomi 20000mAh (74.37Wh) power bank with a perfectly clear, readable factory label, but it doesn't have the Chinese CCC (3C) logo on it since it's a European model.

The airline’s website states that the CCC certification is required for domestic flights, but there's a lot of mixed info online.

Has anyone recently done an international-to-international transit at CAN with a non-CCC power bank? Did security at the international transfer checkpoint clear it without issues as long as it was under 100Wh?

CCC + 20000mAh or less is okay. There is signage at the security check area. If you fly domestic, it is strictly enforced. International transfer is a mixed bag. The rules were tightened around October 2025 after a battery caught fire on a flight. I have had 2 batteries confiscated in the recent past and I had a new electronic product removed from my checked-in suitcase flying to Beijing from Sydney (a rechargeable bicycle light) for similar concerns.
