Can you bring a laptop or spare lithium batteries to China?
A careful separation of China Customs personal-use entry, laptop carriage, spare-battery protection, and airline watt-hour rules.
Usually, a normal personal laptop can travel with you to China, but entry and flight carriage are separate checks. China Customs applies a reasonable personal-use test to passenger baggage; the operating airline sets the flight conditions. Keep a laptop in cabin baggage where possible, and carry spare lithium batteries only in cabin baggage with their terminals protected. Check the printed watt-hour rating and your airline before every flight, especially when a China domestic sector follows your international arrival.

Save before you go
Preserve the evidence needed to identify and explain an item.
- Save the product label, ingredients, specifications, or prescription.
- Keep batteries and restricted items accessible for inspection.
- Leave uncertain items unpacked until the current official rule is checked.

Call only for a real emergency. Say the exact location first; ask nearby staff to help communicate when safe.
Keep Customs entry separate from airline battery rules
China Customs says passenger baggage must be for personal use and in a reasonable quantity based on the trip purpose and length. That entry test does not decide whether an airline will accept a laptop or a battery, and an airline approval does not replace Customs inspection. A normal travel laptop is different from a large set of new devices, batteries for resale, or equipment that is unusual for the visit.
- Pack only the laptop, chargers, and spare batteries you reasonably need for the trip; keep purchase or product details available if the amount could look commercial.
- Use the Goods to Declare channel and ask Customs if an item, quantity, value, or entry requirement is unclear; an officer decides the exact case.
- Check every transit country separately. A battery accepted for the flight into China may face a different local or airline rule elsewhere on the itinerary.
Keep the laptop with you when practical
IATA identifies laptops as portable electronic devices and recommends keeping electronic devices in carry-on baggage. If an airline permits a device in checked baggage, IATA says it should be protected from damage and unintentional activation and completely switched off, not left in sleep or hibernation mode. Cabin-bag space, security screening, and the operating carrier can still change the result for a particular flight.
- Shut the laptop down fully before travel and protect it from crushing, heat, or accidental switch-on.
- If a cabin bag is taken at the gate for the hold, ask the airline before handing it over and remove the laptop and every spare battery when instructed or when carry-on space allows.
- Do not try to conceal a damaged, swollen, leaking, hot, or recalled battery in either bag; tell the airline if a device becomes hot, smokes, or is damaged during the journey.
Treat every spare battery as cabin-only
A spare laptop battery is not the same as the battery installed in the laptop. IATA says spare batteries of any type must be in carry-on baggage, and its passenger guidance says to keep terminals protected against short circuit in original packaging, a protective pouch, or equivalent insulation. Do not place a loose spare battery in checked baggage or loose against metal items, keys, coins, or another battery.
- Put each spare battery in its own protective pouch or original package; cover exposed terminals as the airline instructs.
- Keep the label visible and use the watt-hour (Wh) value printed by the manufacturer rather than assuming that a mAh number alone will be accepted at security.
- A battery of up to 100Wh is generally allowed in carry-on baggage; a battery over 100Wh and up to 160Wh may need operator approval, while a larger battery is usually not permitted in passenger baggage. Confirm the actual airline policy before travel.
Recheck a China domestic flight without extending the power-bank rule
A mainland domestic flight is a separate airline and security event. CAAC's current CCC-marking and recall rule in the cited notice is for power banks on mainland domestic flights, not a general statement that every laptop or installed laptop battery needs a CCC mark. If you also carry a power bank, use the dedicated power-bank guide; for the laptop and a spare battery, follow the operating airline's current instructions and the printed Wh label.
- Do not treat a power bank as a spare laptop battery just because both contain lithium cells: its China domestic CCC and recall check is separate.
- Allow time for staff to inspect the device, battery label, protection, or airline approval at a domestic departure gate.
- Keep addresses, tickets, and essential records available offline so an airline refusal or a gate-checked bag does not leave all critical information in the hold.

Frequently asked questions
Can I put a laptop in checked luggage for a flight to China?
Keep it in cabin baggage when practical. IATA says a laptop may be checked only when the airline allows it and the device is protected from damage and accidental activation and fully switched off, not in sleep or hibernation mode. The operating airline has the final conditions for the actual flight.
Can spare laptop batteries go in checked baggage?
No. IATA says spare batteries must be carried in cabin baggage and protected against short circuit. Keep each battery in original packaging or a protective pouch, protect its terminals, and check the airline's quantity and watt-hour rules before travel.
How large can a spare laptop battery be on a flight to China?
Look at the printed watt-hour rating, not only mAh. IATA says batteries up to 100Wh are generally allowed in cabin baggage; batteries over 100Wh and up to 160Wh may need airline approval, and larger batteries are usually not permitted in passenger baggage. Confirm the operating airline's rule for your route.
Does my laptop need a CCC mark on a China domestic flight?
CAAC's cited mainland-domestic notice specifically covers power banks without a clear CCC mark or from recalled models or batches. It does not state a general CCC rule for laptops or their installed batteries. If you carry a power bank, check its CCC and recall status separately; always follow the airline's current instructions for the laptop and any spare battery.
