Regulatory overview of Chinese Proprietary Medicines

Understand the requirements to import, wholesale, manufacture or assemble Chinese Proprietary Medicines in Singapore.

What is a Chinese Proprietary Medicine

In Singapore, a Chinese Proprietary Medicine (CPM) refers to a medicinal product that:

  • Is in the form of a finished product, such as a capsule or tablet, and
  • Contains one or more active ingredients from any plant, animal or mineral, or any combination of sources. All of the active ingredients have to be documented for use in traditional Chinese medicine.

The following are not considered as CPM:

  • Products to be injected into the human body.
  • Products containing any chemically-defined isolated constituents as an active ingredient.

If you are unsure of your product's classification, you can check using our Complementary Health Products (CHP) Classification Tool to assist you in the classification of common CHP.

Regulatory requirements of CPM

You will need to have a product listing approval and a dealer's licence to import, wholesale, manufacture or assemble CPM for sale and supply in Singapore.

If you are importing the CPM solely for export, product listing and dealer licences are not required, but you will need to apply for a permit for the import of CPM solely for re-export.

Transmissible Spongiform Encephalopathy (TSE)

Animal derived ingredients

Transmissible spongiform encephalopathy (TSE) refers to a group of progressive diseases including scrapie in sheep and goats, chronic wasting disease in mule, deer and elk, bovine spongiform encephalopathy (BSE) in cattle, as well as Kuru and Creutzfeldt-Jakob Disease (CJD) in humans.

The infectious agents causing these diseases replicate and cause neurological disorders and eventual death in the infected individuals. There are currently no early diagnostic tests or known therapies for these diseases.

If your product contains animal derived ingredients, you must comply with our TSE guidelines107 KB to minimise the risk of TSE transmission.
