To carry out corporate activities with integrity, it is necessary to promote sustainability activities by involving the entire network, including suppliers, as our important business partners, as well as Astellas employees interacting with suppliers. To this end, Astellas has the Astellas Business Partner Code of Conduct which requires our business partners to engage in socially responsible operations. This document is intended for use by Astellas' business partners as a code of conduct, which is determined from the view point of social expectation regarding ethics, labor, health and safety, the environment, and the related management system. We require business partners to implement initiatives in accordance with social responsibilities and sign the Acknowledgement of Astellas Business Partner Code of Conduct.
