Prescription Medicines When Moving to China: What to Check Before You Fly

The first check is not a list of banned drugs. It is whether your medicine falls under the ordinary personal-carry rule or under the separate narcotic and psychotropic pathway. Those are two different sets of requirements, and mixing them up is the most common mistake.

For ordinary prescription medicines, Chinese rules do not set a fixed number of days you may bring. The governing standard is self-use and reasonable quantity, and the goods remain subject to customs supervision. That is the rule in Article 39 of the Measures for the Administration of Drug Importation (State Administration for Market Regulation). "Reasonable" is not defined as a day count, so the practical question becomes: what will you be able to explain at the border, and what documentation supports it?

Is your medicine an ordinary prescription drug or a controlled one?

This is the decision point that changes everything downstream.

If your medicine is an ordinary prescription drug, Article 39 applies: personal self-use, small quantity, reasonable amount, customs supervision.

If your medicine is a narcotic drug or a psychotropic drug of the first class, a different provision applies. Article 44(1) of the Regulations on the Administration of Narcotic Drugs and Psychotropic Drugs (Shanghai Municipal Medical Products Administration) allows a person carrying for their own medical treatment to bring up to the maximum amount of a single prescription, provided they hold a diagnosis certificate from a medical institution and personal identity documents. Customs releases it on a self-use, reasonable basis.

So the sequence is: identify the drug class first, then assemble the paperwork that matches that class.

How do you find out whether your specific drug is controlled?

You check the current catalogue. Article 3 of the same regulations states that the medicinal and non-medicinal controlled-substance catalogues can be adjusted. That means a drug's status is not fixed forever, and a list you saved two years ago may no longer be accurate.

The medicinal controlled-substance catalogue is set and adjusted by the national drug regulator with the other authorities named in Article 3. If you cannot confirm a medicine's current classification, treat it as unresolved until the current official catalogue and the competent regulator's information support a conclusion.

Two practical suggestions, clearly labelled as suggestions rather than rules:

• Ask your prescriber to write the generic (INN) name, not only the brand name. Brand names differ between countries and a customs officer may not recognise yours.
• Keep the original prescription and a letter from your doctor stating the diagnosis, the drug, the dose and the duration of treatment. This is not a listed legal requirement for ordinary drugs, but it is the kind of evidence that supports a self-use and reasonable-quantity explanation.

What about the "carrying certificate" people mention online?

There is a second paragraph in Article 44 that is frequently misread. Under Article 44(2), medical personnel carrying a small quantity of narcotic or psychotropic drugs for medical purposes must hold a carrying certificate issued by a drug regulatory department at or above the provincial level.

That provision is written for medical personnel on medical business. It is not a general pathway for ordinary travellers, and it should not be presented as one. If you are an individual patient, your route is Article 44(1) — diagnosis certificate, identity documents, single-prescription maximum — not the medical-personnel certificate.

What should you actually do before departure?

Work backwards from your arrival. The checks that matter, in order:

1. Confirm the drug class against the current official catalogue; an unresolved classification needs confirmation from the competent drug regulator.
2. If it is an ordinary prescription drug, prepare to demonstrate self-use and reasonable quantity. Bring the prescription, the diagnosis information and the medicine in its original packaging.
3. If it is a narcotic or first-class psychotropic, obtain the diagnosis certificate and carry your identity documents. Expect the single-prescription maximum to be the ceiling.
4. Check current customs guidance for your port of entry. The port applies the self-use and reasonable-quantity standard to the facts of your case.
5. Do not assume your home-country prescription is automatically valid for import. It is evidence of medical need, not an import authorisation.

What this article cannot tell you

It cannot tell you whether your particular medicine is permitted, how many days' supply is acceptable in your case, or what will happen at your port. The regulations set standards, not individual outcomes, and this is not a legal or medical determination.

If your situation involves a controlled drug, a long supply, or a medicine you cannot interrupt, classification depends on the current drug-regulator catalogue and entry depends on customs' assessment at the arrival port. Resolve those uncertainties before departure.
