Pharmaceutical Quality (PQ) or Pharmaceutical Quality/Chemistry, Manufacturing & Controls (PQ/CMC) is a term used to describe manufacturing and testing data of pharmaceutical products. PQ/CMC encompasses topics such as drug stability, quality specification, and batch analysis, which are important aspects of drug development. PQ/CMC plays an integral part in the regulatory review process and life cycle management of pharmaceutical products. This is a US Food & Drug Administration (FDA) sponsored project.  To learn more, visit


Latest News:  On May 1, 2023, FDA published a federal register notice including a document of new PQ/CMC data elements and terminologies for public comment.  FDA is only seeking comment on Chapter 2 of the associated document. Comments on Chapter 1 will not be addressed as that content was published for comment previously in March 2022. Click to view the notice and associated document.

NOTE:  FDA refers to this project as Pharmaceutical Quality/Chemistry, Manufacturing & Controls (PQ/CMC)  & at HL7 it is called Pharmaceutical Quality (PQ)


  • Goal of this project is to establish electronic standards for submitting Pharmaceutical Quality (PQ)/Chemistry, Manufacturing & Controls (CMC) data that is part of the eCTD Module 3 data submission (as relevant) to the Food and Drug Administration (FDA).  The PQ/CMC effort is grouped in 2 Phases.
    • Phase 1 – includes development of data standards and data exchange standards for the following sub-domains within PQ/CMC: Drug Product, Drug Substance, Quality Specification, Batch Analysis and Stability.
    • Phase 2 - will include sub-domain such as, Manufacturing process for Drug Product and Drug Substance (API). Other sub-domains of Phase 2 are yet to be determined.

Project Status

  • ACTIVE  (Status Date: 04/2023)

PQ/CMC Project has been developing an Implementation Guide that is scoped to Phase 1.  It is work-in-progress and continues to evolve as new Profiles and examples are added to cover the Phase 1 scope.

FHIR Resources (Draft)

Last Updated: `10/2022

The table below shows the FHIR domain Resources that are planned to be used in Phase 1 of the PQ/CMC Project.  This list may change a bit as we finalize the mappings to FHIR Resources. Phase 1 includes  – Drug Product, Drug Substance, Quality Specification, Batch Analysis and Stability.  The PQ/CMC Phase 1 requirements are represented in the FHIR Resources on

As additional domains of CMC are structured, defined and represented in FHIR, the table below will be updated.
