The Asian Medical Device Nomenclature System (AMDNS) designed specifically for regulatory applications is derived from the Universal Medical Device Nomenclature System (UMDNS). The device codes and terms of these two systems are fully compatible and interchangeable. Applications for listing medical devices under the Medical Device Administrative Control System should use the AMDNS/UMDNS Codes and Terms in the application forms. Should you require any technical assistance, please call (852) 3107 8484.
