For a short visit to mainland China, do not drink water straight from the tap. The US Centers for Disease Control and Prevention currently advises that tap water is not drinkable in China, including major cities. Use an unopened factory-sealed bottle or water that has been properly boiled or otherwise disinfected.
That traveller rule does not mean China has no drinking-water standard. It means a visitor usually cannot verify the source, building plumbing, storage and handling behind a particular tap. The practical choice is to use a water source whose treatment and seal you can check.
The simple decision rule
Use this hierarchy for drinking and food preparation:
- Unopened factory-sealed bottled or canned drinks. Check that the cap ring or seal is intact.
- Water brought to a full rolling boil. Cool it in a clean, covered container.
- A clearly marked direct-drinking or treated-water dispenser. Follow its labels and maintenance notice.
- A traveller water-treatment method used exactly as directed. Filters and disinfectants do different jobs; one device is not automatically suitable for every contaminant.
Ordinary-looking tap water can still carry organisms that cannot be seen. Smell, colour and a modern hotel bathroom are not tests of drinking safety.

China has a national standard, but that does not settle a hotel tap
China’s drinking-water quality standard is GB 5749-2022. The China CDC says it covers water-quality requirements, centralized supply, secondary supply and testing from source to tap. That regulatory framework is important, but a national standard is not a live test result for the faucet in front of you.
For travellers, the CDC destination page gives the more usable instruction: avoid drinking tap water and choose bottled water. This guide follows that conservative advice rather than making city-by-city guarantees.
How to boil water safely
CDC travel guidance recommends bringing clear water to a full rolling boil for one minute. At elevations above 6,500 feet, or about 2,000 metres, it recommends three minutes. Let the water cool naturally and store it in a clean, covered container so that it is not contaminated again.
Boiling is intended to kill disease-causing organisms. It does not remove every possible chemical contaminant. If a local authority has issued a specific water notice, follow that notice rather than assuming boiling solves every problem.
An in-room kettle can be useful if it is clean and working properly. Inspect and rinse it first. Do not use a visibly dirty or damaged kettle, and do not treat warm water as boiled water.
Brushing teeth, ice and hot drinks
CDC food-and-water advice says travellers should use bottled or disinfected water for brushing teeth where tap water may be contaminated. That is the lowest-uncertainty choice in mainland China, especially for young children or anyone following clinician-specific health advice.
Ice is harder to judge because the source water is not visible. If the establishment cannot confirm that it was made with safe water, choose a sealed drink without ice. A polished chain café is not proof of the ice source.
Coffee or tea served steaming hot is generally the safer choice in travel-health guidance. Lukewarm water from an unlabelled dispenser is not equivalent to water that has reached a full boil. At airports, stations and public buildings, use only a dispenser clearly marked for drinking water and follow the hot/cool labels.
Bottled water without guesswork
Choose an intact factory seal and open the bottle yourself. If the cap ring is loose, the seal looks repaired, or the water has an unusual appearance or smell, choose another bottle. Prices and brands vary, so this page does not publish a fixed “normal” price.
Carry a refillable bottle, but treat the refill source as carefully as the original drink. A dispenser may provide potable filtered water, boiling water, or ordinary utility water; the pictogram and Chinese wording matter. Ask staff when the label is unclear.
The China packing list includes practical bottle and medication preparation. For sanitation expectations beyond drinking water, the toilets in China guide explains what to carry without turning normal travel friction into a health scare.
Food, fruit and baby formula
Use safe water for preparing drinks, washing food that will be eaten raw, making ice and mixing infant formula. CDC guidance specifically treats formula preparation as a situation requiring a safe water source. Follow the formula manufacturer’s instructions and any advice from the child’s clinician; this page does not choose a product or preparation method for an individual child.
Peel fruit yourself when practical. If fruit or vegetables will be eaten raw, wash them with bottled or properly treated water rather than assuming a quick tap rinse removes the relevant risk.
If you become unwell, avoid trying to diagnose the cause from one drink of water. Seek appropriate medical advice for severe, persistent or concerning symptoms, and use local emergency services when the situation is urgent.
FAQ
Can visitors drink tap water in Beijing or Shanghai?
CDC’s China traveller guidance says not to drink tap water even in major cities. Use sealed bottled water or properly treated water.
Is boiled tap water safe to drink?
Boiling is CDC’s preferred method for killing disease-causing organisms in water. Bring it to a rolling boil for one minute, or three minutes above about 2,000 metres, then cool and store it cleanly.
Should I brush my teeth with bottled water?
Using bottled or disinfected water follows conservative CDC travel guidance and removes uncertainty about the tap source.
Is water from a public dispenser safe?
Only use it when it is clearly labelled as drinking or treated water and the outlet appears maintained. Ask staff or choose a sealed bottle if the label is unclear.
