Is modafinil a controlled substance in china?

Yes. In China, modafinil is treated as a controlled substance (a psychotropic drug), not an over-the-counter medication. It generally requires a prescription from a licensed physician to possess or use, and any import, export, or sale is subject to strict licensing and regulatory controls. Possessing or distributing modafinil without proper authorization can be illegal.

If you need the exact current status (in case regulations have changed), I can help look up official sources or guide you on how to verify with Chinese authorities.
