3. With this inclusion, the manufacture, supply, possession, import or export of the newly added substances to the Third Schedule of the MDA 1973 as stated in para 2 above, for the purpose of manufacturing of a controlled drug, would contravene Section 10A of the MDA 1973. Any person convicted of this offence shall be punished with imprisonment not exceeding 20 years or with a fine not exceeding S$200,000 or with both. Persons found to have imported or exported this substance without a permit from CNB can be prosecuted under Misuse of Drugs (Controlled Equipment, Material and Substances) Regulations and punishable with imprisonment not exceeding 3 years or with a fine not exceeding S$10,000 or with both.
