Doing Business with Day & Zimmermann: The Defense Industry Initiative Supplier Code of Conduct
We expect all subcontractors and supplier employees to act with honesty and integrity. As a long-time member of the Defense Industry Initiative on Business Ethics and Conduct (DII), Day & Zimmermann joins other defense companies who are committed to conducting business affairs at the highest ethical level and in full compliance with the law. To ensure the promotion of inter-organizational ethics (e.g. each part of the supply chain affects others), while limiting the number of codes flowed to common suppliers in the defense industry, we have officially replaced our former “Ethics Standards and Guidelines for Supplier Personnel” with the DII Model Supplier Code of Conduct, which includes an additional D&Z-specific one-page addendum. This document helps you understand your responsibility as a supplier to Day & Zimmermann and guides you if you are faced with an ethical issue.
