INNOSPEC INC.

Innospec believes that honest and transparent business conduct is vital and is committed to ethical business practicesand actively enforcing compliance with all applicable laws, regulations and rules. We have therefore adopted a Supplier Code of Conduct, pursuant to which our suppliers are required to comply with all applicable laws, rules and regulations, including those related to business integrity, human rights and safety, health and the environment. Innospec engages EcoVadis to conduct corporate social responsibility risk assessments of key suppliers and those operating out of high-risk locations. Among other things, EcoVadis assessments allow us to evaluate supplier policies and actions taken by the supplier and to identify further actions required to enforce compliance with internationally recognized human rights standards and fair labor practices.

We also have an internal protocol to support our review of, and response to, concerns raised regarding our supply chain. Innospec may invoke sanctions against suppliers, up to and including termination of the business relationship, if they violate modern slavery laws.

A copy of the Supplier Code of Conduct is available on our website under “Supplier Relations” at:
