China Flight & Bullet Train Baggage Scanner
China enforces some of the world’s strictest airport and high-speed rail security checkpoints. Over 100,000 power banks, sprays, and Swiss army knives are confiscated from foreign tourists every month. Calculate your device’s exact Watt-hours (Wh) and check forbidden items below.
Power Bank Watt-Hour (Wh) & CCC Scanner
Formula used by airport security: Wh = (mAh × Voltage) / 1000. Most lithium power banks run at 3.7 Volts.
Even if your power bank is under 100Wh, the capacity and Wh rating MUST be clearly printed and legible on the casing. If it is scratched off or unbranded, Chinese security officers will confiscate it with zero exceptions!
Under 100Wh: You can freely bring up to two units in your cabin bag on all domestic flights and high-speed bullet trains. (Never put in checked baggage!).
What Gets Confiscated at Security Checkpoints?
Aerosol Sprays & Sunscreen
Aerosols with flammable flame symbols are 100% confiscated on trains and planes. On bullet trains, non-flammable sprays are capped at 150ml per can.
Swiss Army Knives & Scissors
Unlike European trains where pocket knives are common, Chinese bullet train stations run X-ray scans at all entrances. Blades over 60mm or locking knives are confiscated immediately.
Self-Heating Hotpot Meals (自嗨锅)
Popular souvenir hotpots that use quicklime water reaction heat packets are completely banned on high-speed rail due to hydrogen smoke triggering fire alarms.
Baggage Screening FAQs: Liquids, Drones & Batteries
Detailed official regulations governing luggage on Chinese aviation and rail systems.
Can I put power banks in my checked luggage on flights in China?
STRICTLY FORBIDDEN! Under Civil Aviation Administration of China (CAAC) regulations, lithium-ion power banks must NEVER be placed inside checked baggage. They must be carried in your cabin baggage. Any power bank detected in checked luggage will be forcibly removed by airport security during automated X-ray screening.
What is the CCC mark requirement for power banks in China?
Power banks sold or carried in China must have clearly legible printed capacity and voltage ratings. If the printed text is rubbed off, scratched, or illegible, airport and high-speed train security officers are legally required to confiscate it on the spot. Starting in recent years, power banks manufactured in China also require CCC (China Compulsory Certification).
What are the liquid and spray limits on China bullet trains?
On China high-speed rail (G and D trains), self-pressurized aerosol cans (such as sunscreen sprays, shaving cream, or deodorant) are limited to a maximum volume of 150ml per can. Any container bearing a flammable flame symbol is strictly confiscated.
Are pocket knives and multi-tools allowed on China bullet trains?
No. Swiss Army knives, utility folding blades, craft scissors with blades exceeding 60mm, and pocket knives are strictly prohibited inside Chinese railway stations and will be confiscated at the entry security checkpoint X-ray scanners.
