If you are working to Good Manufacturing Practice (GMP) then you will need to audit many of your suppliers. These could be suppliers of chemicals and packaging components, as well as suppliers of analytical testing or calibration services. GMP does not really tell you what pharmaceutical supplier standards you should or could use when auditing your suppliers. So, below is a list of all the key standards to use when auditing suppliers to GMP requirements including links to all of the key documents and authorities.
Type of supplier | Standard to use | Available from |
---|---|---|
Active ingredients | Use Active Pharmaceutical GMP (EU GMP Part 2 or ICH Q7) | Available for free from the European Union’s Eudralex website. |
Excipients (chemicals that are not the active ingredient) | Use the Joint IPEC – PQG Good Manufacturing Practices Guide for pharmaceutical excipients | Available for free from the International Pharmaceutical Excipient Councils (IPEC’s) website. |
Contact packaging materials | Use either ISO 15378 (Primary packaging materials for medicinal products – Particular requirements for the application of ISO 9001, with reference to GMP) or PS 9000 (Pharmaceutical Packaging Materials for Medicinal Products) | Available to buy from the International Standards Organisation’s website
Available for free from the Pharmaceutical Quality Group’s website. |
Packaging materials | Use PS 9000 (Pharmaceutical Packaging Materials for Medicinal Products) | Available for free from the Pharmaceutical Quality Group’s website. |
External testing laboratories | Use ISO 17025 (General requirements for the competence of testing and calibration laboratories) AND relevant parts of GMP (such as Chapter 6 of EU GMP) | Available to buy from the International Standards Organisation’s website
Available for free from the European Union’s Eudralex website |
Calibration companies | Use ISO 17025 (General requirements for the competence of testing and calibration laboratories) | Available to buy from the International Standards Organisation’s website |
Contract manufacturers | Use the relevant GMP standard for the country or region that they are in, such as EU GMP | Available for free from the European Union’s Eudralex website. |
Transportation companies | Use the EU’s Good Distribution Practice (GDP) guidelines | Available for free from the European Union’s Eudralex website |
Other suppliers | Use ISO 9001 (Quality management systems – Requirements) | Available to buy from the International Standards Organisation’s website |
I hope that list of standards to use when auditing suppliers is helpful. Feel free to add any comments or any additional guidelines and standards that may be of interest.

Annex 1 has finally arrived, 25th Aug 2022 saw the publication of Annex 1. Normally, updates to GMP chapters and Annexes have a 6-month lead time for implementation. In the case of the new Annex 1, the lead time is 12 months, except for clause 8.123 relating to lyophilization which has 24 months lead time.
Annex 1 was first issued in 1971 as the only annex in the first ever UK guide to Good Manufacturing Practice. Since then, there have been several updates but not full revisions. In 2012 there was a proposal to revise Annex 1 with a re-proposal in 2014 by the UK’s MHRA. At the time, a full rewrite was considered unlikely and instead the intention was to provide a document that would confirm regulatory expectation and as such, not place any new requirements or costs on the pharmaceutical industry.
While this principle, is still upheld, it was clear from the first draft for public comment of December 2017, that a rewrite was being undertaken. The first draft created around 6200 comments coming from regulatory organizations, such as the pharmaceutical cooperation scheme, regulatory bodies outside of the EU, support organizations such as the Parenteral Drug Association, the Parenteral and Healthcare Sciences Society, the Pharmaceutical Microbiology Interest group as well as representatives from the manufacturers within the pharmaceutical industry to name just a few. Rarely do updates require a second public consultation but in the case of the annex 1 update a second draft was issued in March 2020 although this was a more targeted review in terms of the sections and clauses that comment was being sought for.
