USP–NF: Upcoming Planned Changes to Title and Format (Updated)

Type of Posting: Publication Announcement
Posting Date: 27–Mar–2020; updated 29–May–2020*

Upon receipt and evaluation of public comments to the PF 46(1) General Notices proposal, the 2015-2020 Council of Experts has approved the following changes to the USP–NF.

Starting with the November 2020 publication, the title of the publication will be USP–NF 2021, Issue 1 (formerly known as USP 44–NF 39). The USP–NF will transition to a new naming convention as follows:

USP–NF 2021 Issue 1 (previously USP 44–NF 39)
USP–NF 2021 Issue 2 (previously First Supplement to USP 44–NF 39)
USP–NF 2021 Issue 3 (previously Second Supplement to USP 44–NF 39)

Please note that there will be no change to the typical minimum six-month implementation period. USP will also continue to publish accelerated revisions and errata on a monthly basis. See the table below for details.

Official Month Publication Title Publication Date Official Date
May USP–NF 2021 Issue 1* 11-01-2020 05-01-2021
August USP–NF 2021 Issue 2 02-01-2021 08-01-2021
December USP–NF 2021 Issue 3 06-01-2021 12-01-2021

*Previously would have been titled USP 44–NF 39

Benefits of this change include:

  • Year-based naming convention better informs the end user of official dates of standards published on each scheduled revision date, with all newly published revisions generally becoming official in the same calendar year, responding directly to stakeholder input received through public survey, Stakeholder Forums, and Project Teams.
  • Supports previously implemented updates to the date-centric revision mark-up and online-only product format.
  • Ensures continuity of publication nomenclature visible to both external and internal stakeholders

Please also see previously posted compendial notice related to the USP-NF Title Change here.

As an update, there had been a previous communication about USP's intent to publish a non-official volume of revisions and additions to the USP–NF, which would have served only as an historical reference document.

Please note that USP has decided not to publish an "non-official" print volume based on feedback received and low demand for the existing print version. Instead of a non-official print version, USP plans on launching a two-column PDF format as a feature of the USP–NF Online in November 2020.

*This Notice was updated on May 29, 2020 to clarify intentions regarding offering a print publication of revisions.
