Can you bring perfume or aerosol toiletries to China?
A cautious guide to perfume, deodorant, hairspray, shaving foam, flight screening, checked-baggage questions, and China Customs checks.
A small perfume or toiletry spray is not just an ordinary bottle: CAAC treats perfume, sprays, hairspray, shaving foam, and aerosol deodorant as liquid items for aviation security. On an international or regional flight, the published carry-on rule is a container of no more than 100 mL inside the one resealable 1 L liquid bag; on a China domestic flight, the narrow cosmetic exception is one item of each type in a container of no more than 100 mL, subject to inspection. Those screening limits do not decide whether a pressurised or flammable product can be checked, whether another airport or operating airline is stricter, or whether China Customs will clear an unusual quantity. Check the exact labelled product and your actual itinerary before you pack it.

Emergency numbers in China
Call only for a real emergency. Say the exact location first; ask nearby staff to help communicate when safe.
First identify the spray, not only the brand
Treat a pump perfume, aerosol deodorant, hairspray, dry shampoo, shaving foam, insect repellent, and defensive spray as different packing questions. CAAC's security rules include perfume, sprays, hairspray, shaving foam, and pressurised deodorant among liquid items. The same CAAC travel guidance lists pepper spray, tear gas, acidic sprays, and animal-deterrent sprays among items prohibited from carriage. If you cannot tell what a product contains or what it is designed to do, leave it out of the travel bag and obtain a suitable product after arrival instead of asking a checkpoint to classify an unknown can.
- Read the complete label before packing: product name, volume, ingredients, flammability or pressure warnings, and whether it is a cosmetic, medicine, disinfectant, repellent, or defensive product all matter.
- Do not relabel, decant, pierce, or disguise a pressurised or uncertain product to make it look like an ordinary toiletry.
- Do not treat a defensive, irritant, animal-deterrent, or unknown spray as a personal-care item; use lawful, non-spray alternatives and follow the carrier's current directions.
Pack a cabin toiletry spray by the route's liquid rule
For international and regional flights, CAAC says carry-on liquid items must be in individual containers of 100 mL or less and placed in one resealable transparent bag of up to 1 L. The container capacity matters, not how much remains. For China domestic flights, CAAC says liquid items are generally not carried in the cabin, with a limited exception for cosmetics used during the flight: one item of each type, in a container of no more than 100 mL, subject to opening and inspection. A spray that passes one security point is not automatically accepted on a later flight or domestic connection.
- Use a clearly marked container of 100 mL or less only if the product and route otherwise meet the applicable carry-on rule; a partly used larger can is not made compliant by its remaining contents.
- Keep the product reachable for inspection and give yourself time to follow staff directions; security may require an opening check for the domestic cosmetic exception.
- For a China domestic connection, plan the checkpoint as a new decision rather than assuming the international liquid bag will pass unchanged.
Ask the operating airline before checking any aerosol
The published CAAC liquid-screening rule says that liquid items beyond the carry-on allowance may be checked, subject to carriage conditions, but it is not a blanket approval for every aerosol, pressurised can, flammable fragrance, medicine, disinfectant, or repellent. The operating airline controls its own baggage and dangerous-goods acceptance for the actual flight, and a transit country or codeshare itinerary can add another rule. Contact the carrier with the exact product name, label, container volume, and route before placing an aerosol in checked baggage; keep a simple non-aerosol alternative if the answer is not confirmed.
- Do not infer that an aerosol is checked-baggage-safe solely because it is over the cabin liquid limit or sold as a cosmetic.
- Keep original, readable retail packaging and protect a confirmed permitted toiletry against leakage or accidental activation as the carrier directs.
- If the airline cannot confirm the product in time, do not gamble on a short connection or an airport disposal decision; buy an acceptable alternative after arrival.
Keep Customs entry separate from flight screening
A security result answers only the flight-screening question. China Customs separately requires inbound passenger articles to be for reasonable personal use and accurately declared, and can inspect items or require the applicable formalities. A normal personal toiletry quantity may be straightforward, but multiple cans, commercial-looking quantities, an unfamiliar chemical, or any product that is medicine, disinfectant, or otherwise regulated needs an item-specific check. Use the goods-to-declare channel and ask Customs when the quantity, product status, or paperwork is unclear.
- Keep the original label and, for a costly or unusual product, the receipt available for a Customs question.
- Do not treat a 100 mL screening limit as a Customs allowance, an admission decision, or a promise that duty will not apply.
- Use the dedicated alcohol-and-sanitizer guide for products with alcohol or disinfectant claims; their rules are not the same as an ordinary fragrance or toiletry spray.

Frequently asked questions
Can I take a 100 mL perfume spray in my carry-on to China?
It can still depend on the route and the exact product. CAAC classifies perfume and sprays as liquid items. For an international or regional flight, a container of 100 mL or less must fit in the one resealable 1 L liquid bag; China domestic flights use their own, narrower cosmetic exception. A transit airport or operating airline can be stricter, so check every segment before travel.
Can I check hairspray or aerosol deodorant in baggage?
Do not assume that you can. A cabin liquid limit does not by itself approve a pressurised or potentially flammable product for checked baggage. Ask the operating airline about the exact labelled product, volume, route, and any dangerous-goods conditions before packing it; choose a non-aerosol alternative if acceptance is not confirmed.
Can I bring pepper spray to China for personal safety?
Do not pack it as travel baggage. CAAC lists pepper spray, tear gas, acidic sprays, and animal-deterrent sprays among prohibited carriage items. That aviation rule does not settle every legal question, but it is already enough reason to leave these products out of a flight bag and seek lawful local safety guidance instead.
Does airport security approval mean Customs will allow my perfume or spray into China?
No. Airport screening and Customs entry are separate decisions. Customs applies personal-use, declaration, and item-specific requirements independently. Keep normal quantities and original labels, and declare or ask Customs if the product, quantity, or required paperwork is uncertain.
