What Proof Documents Must Be Prepared for Carrying Medications (Such as Prescription Medicines) when Entering China?

Small quantity of medicines carried by passengers at the entry and exit shall be limited to self-use and reasonable amount, and shall be subject to the supervision of the customs.

When carrying personal medications across borders, you should carry a medical certificate issued by a legitimate medical institution to prove that the medications are indeed needed for health reasons. This will help customs authorities determine a reasonable quantity of medications to carry based on the original valid prescription. Unless otherwise specified by a doctor with special reasons, the reasonable quantity of prescribed medications generally should not exceed a seven-day supply.
