Ordinary medicine: reasonable quantity, personal use
Travellers carrying small quantities of medicine for personal use when entering or leaving China must limit them to reasonable quantities for personal use and accept customs supervision. That is the whole published rule for anything with no narcotic or psychotropic content.

Controlled medicine needs a diagnosis certificate and a passport
Under the Regulations on the Administration of Narcotic Drugs and Psychotropic Substances, an individual who needs such medication for treatment must present a medical diagnosis certificate issued by a medical institution and a valid identity document such as a passport. Both the Shanghai and the Chongqing answers state this.

The ceiling is one prescription, and a prescription is short
You may carry narcotic drugs and Category I psychotropic substances up to the maximum quantity permitted on a single prescription. Chinese prescription management rules cap that at a single dose for injectables, a three-day supply for other formulations, and a seven-day supply for controlled-release and sustained-release preparations.

The children's ADHD exception is published
Where methylphenidate is used to treat ADHD in children, each prescription may not exceed a 15-day supply. That is the longest single-prescription figure the Shanghai answer publishes.

Category II gets more room
For Category II psychotropic substances the prescribed quantity may be extended where appropriate to cover a longer period. Neither opened answer says by how much, or who decides.

Declare it. Do not walk the green channel with it
Both customs answers tell travellers carrying medicine into or out of China to bring supporting documents such as prescriptions, medical records or certificates of diagnosis, and to proactively declare the medicine to customs officers at the port of entry or exit.

The officer at the desk still decides
Chongqing Customs closes its answer by stating that clearance remains subject to the customs authority's on-site review. Meeting the published quantity and carrying the documents is what you control; it is not a guarantee of release.

What is banned outright, in the customs guide's own list
Opium, morphine, heroin, marihuana and other addictive drugs and psychotropic substances are on the list of articles prohibited from importation, alongside deadly poisons and medicine coming from an epidemic-stricken area or harmful to people and livestock.

The ban runs both ways, and covers the post
All items prohibited from entering China are also prohibited from leaving China, and individuals may not send such items into or out of China by post. Posting your own medication ahead of you is not a way around the carrying rules.

Classification is Chinese, not yours
Narcotic drugs and psychotropic substances mean the drugs and substances listed in China's own catalogues, with psychotropic substances split into Category I and Category II. The Shanghai page attaches both catalogues as downloadable files. A medicine sold over the counter at home can sit in Category I here.

Do not plan on replacing it locally
The UK foreign ministry states that the legal status and regulation of some medicines prescribed or bought at home differ in other countries, that certain medicines may not be available in China, and that you may not be allowed to bring others in. Its advice is to bring enough with you and check with your prescriber and the Chinese Embassy first.

The legal basis, as the customs answer names it
Chongqing Customs cites Decree No. 442 of the State Council and Decree No. 43 of the General Administration of Customs. The Shanghai answer cites the Regulations on the Administration of Narcotic Drugs and Psychotropic Substances. Those are the instruments behind every quantity on this page.
