Bringing medical devices into China customs is rarely the obstacle people expect. China does not stop travellers from carrying a CPAP machine, a glucose meter or a walking frame for their own use, and most arrivals walk through with nothing more than a bag scan. The trouble starts when a device looks unfamiliar on the X-ray, when the paperwork is missing, or when the equipment is in the wrong bag. This guide covers what to pack, what to declare, and how to keep a checkup trip from stalling at the airport.
What Counts as a Medical Device You Are Bringing In
Practically every personal health item qualifies: anything with a motor, a battery, a sensor or a compressed part. Officers see these daily, but each category raises a slightly different question, so it helps to know which one you are carrying.
CPAP, BiPAP and other breathing machines
A CPAP or BiPAP unit is bulky but plainly personal — one mask, one hose, one machine. Keep the machine, mask and spare in one bag so the set reads as a single unit on the scanner. Bring the original carry case with the manufacturer’s label visible; it identifies the device faster than you can explain it.
Glucose meters, test strips and insulin cooling cases
A glucose meter, a lancet pen and a few boxes of strips are unremarkable. An insulin cooling case is the item that gets a second look, because it is a hard shell with a cold pack inside. If you use insulin, keep the pen and the case together with the pharmacy label and your prescription within reach.
Mobility aids, orthotics and hearing aids
Wheelchairs, rollators and walking frames travel free on most airlines if you tell them in advance, and they are treated as personal mobility equipment rather than cargo. Orthotics and hearing aids need no declaration at all. Mobility aids requested at a Chinese hospital are a separate matter — see our guide for new arrivals.
Lithium Batteries, Nebulisers and Consumables
The parts that cause the most friction are not the devices at all — they are the power supply and the refills.
Lithium batteries and spare power packs
Spare lithium batteries must travel in cabin baggage, never in the hold, and airlines cap the watt-hour rating per battery. Tape the terminals or keep each battery in its own pouch so it cannot short, and carry only what the trip needs. A power bank for a portable nebuliser counts as a spare battery, so the same rules apply.
How much of a consumable to bring
Bring enough strips, sensors, insulin or nebuliser solution to cover the whole trip plus a modest buffer, and keep that buffer modest. A reasonable personal supply clears without comment; a suitcase of identical boxes invites a commercial-goods question. If you are staying for months, buy consumables locally instead — the same logic we set out in our guide to travelling with a medical condition.
Hand Luggage vs Checked Bags: Never Check the Devices You Rely On
Two rules cover almost every case: the device you depend on stays with you, and everything you could replace goes below.
Why the hold is the wrong place for a device
Checked bags get lost, delayed and mis-routed. A CPAP, an insulin pen or a wheelchair in the hold can mean a missed night of treatment or an arrival with no equipment at all. Carry the device, its charger and one set of consumables in the cabin; if the airline insists on weighing hand luggage, the medical bag is normally excluded — ask at check-in.
What does belong in checked baggage
Bulky extras belong below: a second mask, the spare charger you will not need mid-flight, cleaning supplies, and the printed paperwork in a folder. Put a one-page copy of your device list in the checked bag too, so you still have something to show if the cabin bag is separated from you.
Customs Paperwork and the Declaration Channel
Documentation turns a five-minute conversation into a two-minute one. None of it needs translation, but all of it should be dated within the last year where possible.
The one-page device list
Write a single page listing each device, its model number, its serial number and its approximate purchase value. This mirrors what an officer is trained to ask, and a printed list answers model, serial and value before anyone has to open anything. Keep one copy in the cabin bag and one in your wallet.
Doctor’s letter, prescription and the manual
Carry a short letter from your doctor on letterhead naming the devices, confirming they are for your personal use, and stating the condition in general terms. Add the original prescription or purchase receipt, and the device manual with the specification page bookmarked. The manual is the quiet hero — it shows the watt-hour rating, the power requirement and the fact that the item is a medical product, not a resale item.
Which channel — and answering a question about an unusual device
Use the green channel for ordinary personal devices, and the red channel when you are carrying something that looks commercial, high-value or genuinely odd, and whenever you have a device to declare. If an officer asks what a strange-looking item is, answer three things in order: what it does, who it is for, and that it leaves with you. Point to the device list, offer the manual, and stay factual rather than persuasive. Our case studies show how these judgment calls play out in practice.
Carried, Shipped or Bought Locally
The rules differ sharply depending on how the device reaches China, and mixing the three is where people get caught out.
Personal-use equipment you carry
Equipment in your own bags, for your own use, that leaves with you at the end of the trip sits in the simplest category. No duty is normally due on used personal medical equipment, and the paperwork above is enough to prove that is what it is.
Equipment you ship in or buy in China
Anything you ship as cargo, or buy after arrival, enters as an import and can attract duty and a different set of forms. If a device is being posted to you, list it honestly on the courier paperwork and expect the recipient to handle clearance. If you plan to buy a device in China, ask the clinic or supplier about documentation before you pay, and fold the sourcing question into your medical visa checklist.
What a supplier or clinic should document for you
If you are buying equipment locally, ask for an invoice in the device’s name, the model and serial number, and a note that it is for personal medical use. This costs you nothing and protects both warranty and resale. Costs vary by hospital and supplier, so there is no single figure to quote — the structure is what matters, and we break that down in our medical cost comparison.
None of this is complicated with a little preparation: keep your devices in the cabin, carry a one-page list, declare the odd item, and travelling with medical equipment becomes routine. Send us your situation — which devices you use, how long you are staying, and whether the trip is clinic-bound — and we will put together a plan that gets you through the airport and into your checkup without the device being the thing that holds you up. Send us your situation and we will take it from there.
