Drug Master Files (DMF)

A Drug Master File (DMF) is a submission to the U.S. Food and Drug Administration (US FDA) that may provide confidential detailed information about facilities, processes, or articles used in the manufacturing, processing, packaging, and storing of one or more human drugs. The submission of a DMF is not an FDA requirement by law or US FDA regulation. A DMF Submission is solely at the discretion of the DMF holder. The information contained in the DMF may be used to support an Investigational New Drug Application (IND), a New Drug Application (NDA), an Abbreviated New Drug Application (ANDA), another DMF, an Export Application, or amendments and supplements to any of this submission.

A DMF is not a substitute for an IND, NDA, ANDA, or Export Application. It is not approved or disapproved; technical contents of a DMF are reviewed only in connection with the review of an IND, NDA, ANDA, or an Export Application. US FDA will issue a DMF number to each submission. DMF number does not denote registration of the facility or product. US FDA is not issuing a certificate of FDA registration nor does US FDA recognize a registration certificate issued by a third party. FDA encourages foreign DMF holders to appoint a U.S. FDA Agent.
