In April 2019 Ethical Consumer viewed Pfizer's website, www.pfizer.com, for the company's supply chain management policy. A statement on human rights was found which stated the Pfizer fullyed supported the principles of the United Nations Declaration on Human Rights and the International Labour Organisation Declaration on Fundamental Principles and Rights at Work, and "strives to uphold human rights in all our business activities."

A document called Pfizer's Statement of Compliance - California Transparency in Supply Chain Act stated that the copmany was a founding member and participant in the Pharmaceutical Supply Chain Initiative (PSCI) which had developed the Pharmaceutical Industry Principles for Responsible Supply Chain Management. Pfizer stated that it expected its suppliers to adhere to the principles which included adequate clauses on child labour, forced labour, discrimination, and freedom of association. Working hours and wages were defined by local laws. However the information was not linked to in the company's Blue Book: Summary of Pfizer Policies on Business Conduct. It was therefore unclear how it communicated this information to suppliers and was considered to have an inadequate supply chain policy.

No information on its website could be found relating to stakeholder engagement, auditing and reporting or difficult issues.

Overall Pfizer received Ethical Consumer's worst rating for its supply chain management policy.

In April 2019 Ethical Consumer viewed Pfizer's Securities and Exchange Commissions filing 10-K exhibit 21. The document listed the coompany's subsidiaries and the country they were incorporated. The countries included the Philippines, Russia, Venezuela, Thailand, China, Pakistan, Israel, India, Colombia, Saudi Arabia and Nigeria. At the time of writing each country listed was considered by Ethical Consumer to be governed by an oppressive regime.
