PIC/S GMP Annex 1 and the EU GMP Annex 1: are they the same document? Almost, but not quite. The technical text is identical apart from minor wording corrections, while the legal framework, the audience and the way the document lands on an inspector's desk all differ. For sterile manufacturers selling into several markets the distinction is far from academic: a site inspected by TGA, Swissmedic or HSA is assessed against the PIC/S version, not against EudraLex. In this article we look at what the Annex 1 of the PIC/S GMP Guide is, the timeline of the joint revision with the European Union, the real differences between the two versions and what they mean in practice for QA and production.
PIC/S GMP Annex 1: what it is and what it is for
PIC/S (Pharmaceutical Inspection Co-operation Scheme) is the co-operation scheme between inspection authorities created to harmonise GMP standards and inspection practices globally: today it brings together more than 50 authorities, from the European agencies to TGA (Australia), Swissmedic (Switzerland), HSA (Singapore), Health Canada and the US FDA. Its main instrument is the PIC/S GMP Guide (PE 009), structured like the EU GMP Guide: Part I, Part II and a series of Annexes.
Annex 1 of the PIC/S GMP Guide, "Manufacture of Sterile Medicinal Products", is the chapter dedicated to sterile manufacturing: cleanrooms and Grade A/B/C/D classification, Contamination Control Strategy (CCS), barrier technologies (RABS and isolators), Aseptic Process Simulation, sterilisation and environmental monitoring. For member authorities that do not apply EudraLex, this is the reference text used during sterile inspections.
Keep the levels distinct: PIC/S inspects no one and licenses no one. It is the inspectorate that is bound to the scheme, not the company; a manufacturing site encounters PIC/S through the authority that inspects it, through the training its inspectors receive within the scheme and through the interpretive documents (the PI series and aide-mémoires) they use to prepare the audit. That is why knowing the PIC/S version of Annex 1 matters even for teams that work with EudraLex every day.
The joint EU–PIC/S revision: the dates that matter
The Annex 1 revision was run as a joint exercise between the European Commission, EMA, PIC/S and WHO: one working group, one final text, two parallel publications. The co-operation agreement between EMA and PIC/S specifically provides for the harmonisation of the two GMP Guides. The timeline:
- 25 August 2022: the European Commission publishes the revised Annex 1 of EudraLex Volume 4.
- 9 September 2022: PIC/S publishes its own version, identical apart from minor wording corrections.
- 25 August 2023: both versions enter into force on the same day; on the PIC/S side the revised Annex 1 enters the Guide with version PE 009-17.
- 25 August 2024: deferred deadline for point 8.123 only, covering manual loading and unloading of lyophilizers.
The result is the highest level of harmonisation ever achieved on a GMP chapter: the same technical requirement applies, on the same date, across Europe and all PIC/S countries.

The differences between PIC/S Annex 1 and EU Annex 1
If the technical content coincides, where do the differences sit? Almost entirely outside the text of the requirements:
| Aspect | EU Annex 1 (EudraLex Vol. 4) | PIC/S Annex 1 (PE 009) |
|---|---|---|
| Legal nature | Interpretation of the GMP principles laid down in EU pharmaceutical legislation: de facto binding on manufacturing authorisation holders in the EU/EEA | Reference standard adopted by member authorities, each transposing it under its own national framework |
| Audience | Manufacturers and importers in the EU/EEA, QPs, Member State authorities | Inspectorates of PIC/S authorities and, by extension, the sites they inspect worldwide |
| Regulatory references | Refers to EU directives, regulations and structures | References to EU legislation replaced by neutral wording adapted to a multi-country context |
| Technical text | Reference text of the 2022 revision | Identical, with minor wording corrections declared by PIC/S itself |
| Location | EudraLex Volume 4, Annex 1 | Annex to the PIC/S GMP Guide PE 009 (from version PE 009-17) |
A frequent error in gap assessments is citing "Annex 1" without specifying which version and which edition of the guide: for a site inspected by a non-EU PIC/S authority, the correct citation is PE 009 in its current edition, not EudraLex.
What this means in practice for QA and sterile production
For the day-to-day work of a sterile site there are three operational consequences:
- One CCS for all markets: since the technical requirement is the same, the Contamination Control Strategy, cleanroom qualifications and APS programme built on the EU Annex 1 also cover inspections by PIC/S authorities, and vice versa. No parallel dossiers are needed.
- Watch your citations and editions: the PIC/S GMP Guide is renumbered at every update (PE 009-17 introduced the revised Annex 1; later editions update other chapters and annexes). SOPs and VMPs should cite the correct document and edition for the target market.
- Same text, different inspection sensitivities: textual harmonisation does not guarantee uniform interpretation. Expectations on the CCS, environmental monitoring trends and the justification of "shoulds" remain tied to each authority's practice: audit preparation should be calibrated to who is inspecting, not only to what the text says.
Companies exporting to Australia, Switzerland, Canada or South-East Asia should also keep an eye on the PIC/S website: new editions of PE 009 and the interpretive PI documents (such as the aide-mémoires inspectors use) often anticipate the questions that will come up in audits. Harmonisation also helps between authorities: an inspection outcome based on a shared text is more readily recognised by the other agencies in the scheme, reducing the risk of duplicate inspections of the same site.
GuideGxP recommendation
Treat the PIC/S–EU alignment as an advantage to be documented, not a detail to be taken for granted. In practice: cite explicitly, in your CCS and protocols, the Annex 1 version applicable to your authorisation context; maintain a matrix of the markets you serve with the competent inspection authority and the GMP reference it applies; and at every new edition of PE 009 check through change control whether the annexes relevant to your site have changed. Ten minutes of review at each release avoid the classic "obsolete reference" observation in audits.
