Code of Conduct for Suppliers

At ASML, we conduct business on the basis of fairness, good faith and integrity, and we expect the same from our partners and suppliers. ASML became a member of the Responsible Business Alliance (RBA) in 2011 and adopted the RBA Code of Conduct, which provides guidance in four critical areas: labor, health & safety, environment and ethics. To reinforce our commitment to the supplier network, we expect our key suppliers and their suppliers to comply with the RBA Code of Conduct and to develop their own strategies, policies and processes to follow it.
