Short answer: Yes, you can bring your own medicine into China, and most travellers never get a second look. The test customs applies is simple: personal use, reasonable quantity, in the original packaging. What trips people up is a short list of ingredients China regulates as narcotics, psychotropic substances or precursor chemicals, and several of those sit inside ordinary Western cold, cough and pain products. Carry your prescription, carry a doctor's letter, declare anything controlled, and you will clear the border in minutes.
The test customs actually applies
China's Customs Law, the Pharmaceutical Administration Law and the 2026 implementing regulations of that law all use the same phrase for travellers: medicines carried for personal use, in reasonable quantity, under customs supervision. There is no published gram limit. An officer judges whether the amount fits your length of stay and your stated condition, which is why one inhaler and one box of tablets is unremarkable, while six identical boxes look like stock for resale. Resale, bulk gifting and buying on someone else's behalf are the lines that turn a personal supply into a customs case, with outcomes running from return to origin and duty through to seizure.
Customs guidance published in 2026 puts a short leisure or business trip at roughly a seven-day supply of a prescription medicine, with a longer but still reasonable quantity allowed for people staying for months who take it daily. That is guidance rather than a statutory cap, and it is a sensible figure to pack to: what you need for the trip plus a few days of buffer for a delayed flight, not the whole three-month refill.
Paperwork worth carrying
None of this is asked for at every port, which is exactly why you carry it. First, a printed prescription or dispensary label showing your name, the drug name, the dose and the prescribing doctor. Second, a short letter on the doctor's letterhead stating your diagnosis, the medicine, the dose and that it is for your personal use. Third, the medicine in the box the pharmacy dispensed it in, with a legible label. Do not decant tablets into an unlabelled weekly organiser and expect the label to save you.
Two extras pay for themselves: the generic name written in Latin and Chinese characters, since a Chinese pharmacist will recognise the generic long before the brand, and photographs of the whole set in case the paper goes missing.
What is actually restricted
Four brackets, and the paperwork scales with them.
| Bracket | Examples | What you may carry | What to have with you |
|---|---|---|---|
| Narcotic drugs and Category I psychotropics | Morphine, fentanyl, codeine, amphetamine and methylphenidate products (Adderall, Ritalin, Vyvanse, Concerta) | No more than the maximum quantity on a single prescription, for your own treatment | Diagnosis certificate from a medical institution, your passport, and a declaration at the border |
| Category II psychotropics | Diazepam and similar sedatives, zolpidem, tramadol, dextromethorphan, codeine cough syrups | The prescribed quantity, which customs may extend to cover a longer stay | Prescription, doctor's letter, declaration |
| Ephedrine and pseudoephedrine products | Cold and allergy tablets and syrups carrying a -D suffix | Personal-use preparations in reasonable quantity only | Small quantity, original packaging, no stockpiling |
| Cannabis, CBD and hemp products | CBD oil, gummies, creams, THC edibles | Nothing, in any quantity, for any reason | Leave them at home |
A fifth category is refused regardless of paperwork: counterfeit, expired or unlabelled medicine, and traditional Chinese medicines containing endangered animal or plant ingredients such as musk, tiger bone or rhino horn. That last point catches shoppers rather than smugglers, since these products are openly sold in some markets and are still barred from crossing a border.
One thing the table cannot show: vaccines, sera and antibody products count as special biological items and need health quarantine approval arranged before you travel, not at the airport.
The everyday medicines that cause the most trouble
Most seizures at Chinese ports are not smuggling attempts. They are a traveller's own cough syrup.
Attention-deficit medication is the biggest trap for visitors from North America, because Adderall, Ritalin, Vyvanse and Concerta all sit in the strictest bracket. A month's supply without a diagnosis certificate is not a paperwork problem, it is a controlled-substance problem. If you take one of these, talk to your prescriber about a non-stimulant alternative for the trip, or start the documentation weeks before departure rather than days.
Codeine appears in painkillers and cough syrups sold over the counter in some countries. In China it is a narcotic in tablet form and a Category II psychotropic in the compound cough syrups, controlled since 2015. Dextromethorphan, the cough suppressant in a great many syrups and lozenges, moved onto the Category II psychotropic list on 1 July 2024 as a single-ingredient medicine, so a plain DXM syrup now travels as controlled rather than as a grocery item. Tramadol has been Category II since 2008, and its compound preparations joined the list on 1 July 2023. Pseudoephedrine, the decongestant behind that -D suffix, is a Category I precursor chemical in China; personal-use preparations are permitted in reasonable quantity, but the phenylephrine versions, marked PE, avoid the conversation entirely.
Cannabis is where there is no discretion at all. CBD oil, hemp creams, gummies and THC edibles are prohibited whatever their status where you bought them, and CBD itself was added to China's controlled precursor list in 2024.
If you take a medicine every day
Bring the full supply for the trip rather than planning to refill. Chinese hospitals and chain pharmacies can dispense to foreign patients, but the registration desk, the appointment and the brand-name mismatch turn a ten-minute errand into half a day, and a chronic medicine is the worst thing to run out of in a city where you do not read the labels.
Insulin and injectables travel fine in hand luggage with a doctor's letter. Ask the airline about cold-chain handling if the product needs refrigeration, and keep it with you rather than in checked baggage, where a hold delay in summer can ruin it. Carry a printed list of your medicines, generic names and doses included, in your wallet.
Declare, do not explain later
If your bag holds anything in the controlled brackets, use the red channel and say so before the bag goes through the scanner. A declared controlled medicine with matching documents is usually a short conversation with an officer. The same medicine found undeclared reads as concealment, and concealment is what turns a customs matter into a legal one, with consequences that outlast the trip.
