See attached checklist for KGMP audit.
The audit will be for 4-5days; depending upon the device classification and size of the site and QMS complexity, the # of auditors could be 1-3 including a 3rd party and MFDS auditors. If class 2, only a 3rd party auditor will inspect the facility.
Take note that all costs are to be borne by the Korean Importer as per the MFDS regulations, but it depends on the agreement between Korean Importer and Foreign Manufacturer.
Hope this helps!
