Type of Posting: General Announcement
Posting Date: 31-Oct-2024
The targeted official dates for PF 50(5) and PF 50(6) have changed due to the implementation of the new USP-NF publication model on July 25, 2025. The new dates are as follows:
Original Target Official Date: 1-May-2026
New Target Official Date: 1-Feb-2026
PF 50(5) files reflect the original target official date of 1-May-2026, however the new target official date is 1-Feb-2026. The new targeted official dates will be accurately reflected in the PF 50(6) files published on 1-Nov-2024.
This change is necessary to align with our new USP-NF publication model, which aims to provide subscribers with expedited publishing timelines, a regular publishing cadence, and a single bi-monthly source for official content. For more information on the new publication model please visit our informational website.
