Mfds Rollout Plans For Udi RequirementsAdjustments to Korea Good Manufacturing Practice (Kgmp) AuditsExpenditure Report Requirements Spelled OutAdditional South Korean Regulatory ResourcesFirst, the MFDS has clarified plans to phase in UDI requirements for all classes of medical devices over the next several years, and further explained associated compliance obligations for registration holders. “The current law for medical devices provides little basis for understanding a device’s status from its production or importation stage to its distribution stage,” says In-Wha Kim, Regulatory Affairs Specialist at Emergo’s South Korea office. Therefore, according to Kim, MFDS will be introducing a UDI system, requiring manufacturers, importer and distributors to report supply histories, and establish a Medical Device Information Center according to a seminar the ministry held in January 2017. UDI enforcement would come into effect in 2019 for Class IV and high-risk devices; 2020 for Class III devices; 2021 for Class II devices; and 2022 for low-risk Class I devices.
