Code of Conduct

Committed to promoting and upholding ethical behavior

Our Code of Conduct sets out the baseline of ethical behavior at ASML. It details our principles and guides our employees in making the right decisions and living up to our values. The Code helps ASML maintain the highest standard of ethics, integrity and respect, ensuring we are not only a responsible business partner, but that we compete in a fair manner.

We provide a dedicated Ethics Program, which offers the necessary support, advice, training, and communication to enable employees and others to understand and follow our Code of Conduct.

Code of Conduct for Suppliers

ASML conducts business on the basis of fairness, good faith and integrity, and expects the same from parties with whom we do business. ASML became a member of the Responsible Business Alliance in 2011 and adopted the RBA Code of Conduct, which provides guidance in four critical areas: labor, health & safety, environment and ethics.

Anti-Bribery and Anti-Corruption Policy

We are committed to personal and business integrity and avoiding improper influence on others or ourselves. Our Anti-Bribery and Anti-Corruption Policy details our commitment and the measures we take to prevent bribery and corruption at ASML. It also ensures compliance with applicable laws prohibiting domestic and foreign bribery and corruption as well as the ASML Code of Conduct.

Competition Law Compliance Policy

We are committed to the principles of fair competition and fairness in dealing with our business partners, including suppliers, co-developers, customers and other industry peers. As such, ASML does not condone any form of conduct that is considered illegal under applicable competition laws or is contrary to our Code of Conduct. Our Competition Law Compliance Policy demonstrates our ongoing commitment to ensuring compliance with applicable competition laws and our Code of Conduct.

  • ILO Declaration on Fundamental Principles and Rights at Work

Because ASML is committed to upholding human rights standards and guidelines we make sure that within our value chain the human rights are:

Respected: As a company we aim to avoid any human rights violations in operations in which we have direct or indirect involvement .

Protected: We frequently assess actual and potential human rights risks in our own operations and in our supply chain. We educate employees about the importance of human rights and cooperate with the international community and our business partners in preventing human rights violations.

Remediated: We ensure that any (potential) human rights violations within our value chain can be reported to ASML through a grievance mechanism (our Speak Up policy) and that such incidents are addressed with the appropriate level of priority.
