Guidance on Changes to Registered Medical Devices
HSA GN-21 Revision 7 (July 2026). Exact PDF resolved from the official go.gov.sg/gn-21-r7-31-07-2026 collection shortlink. Ingested as sec-1 through sec-6 plus Annexes 1 to 3; only the qualified "to GN-21" annex headings promote, so the Annex 1 document-table captions stay tabular text.
