What makes a requirement binding here
The Health Products Act 2007, in its 2020 Revised Edition — a revision incorporating all amendments up to and including 1 December 2021 and coming into operation on 31 December 2021. Its long title is precise about the reach: an Act to regulate the manufacture, import, supply, presentation and advertisement of health products and of active ingredients used in the manufacture of health products. The Act commenced on 1 November 2007, with the exception of Part 14, whose commencement was left to ministerial notification in the Gazette.
Through the Health Sciences Authority, administering the Act and the subsidiary legislation made under it. Singapore has been a PIC/S Participating Authority since January 2000, and the HSA is the participating body. The Act regulates activities rather than only products: manufacture, import, supply, presentation and advertisement are each a controlled activity, so an organisation can fall inside the Act by advertising a product it does not make.
