Furthermore, by engaging in themes such as the environment,quality/product safety, and employment/human resources and other social issues, we are striving to be a company that has the power to be selected by customers.

Standards of Business ConductSustainability Management System
With the aim of fulfilling TAMRON’ s corporate social responsibility and contributing to the development of a sustainable society, the CSR Committee, whose members include full-time directors, full-time Audit & Supervisory Committee Members and executive officers, meets five times a year in principle. The committee makes decisions on and deliberates over basic matters, policies and important targets concerning CSR and promotion of the integrated management system, and also manages the progress of important targets.
Tamron has formulated a Code of Conduct as a foundation for corporate behavior. The Code is also incorporated into Tamron’s Integrated Management Manual, which is a core regulation in Tamron’s management system that integrates ISO 9001 quality and ISO 14001 environmental standards.
This system is applied across all departments to promote compliance with laws, respect for fair social rules, and high ethical standards. All related internal rules are developed in alighment with this principle, and activities based on this system are audited at least once annually by internal auditors or external audit organizations.

Process for Identifying Key Sustainability Issues

Firstly, we identified social issues surrounding TAMRON based on international guidelines. We then assessed the importance of those issues for various stakeholders, and the possibility and potential impact of any risks. After considering the validity of the results of our assessment, we identified key sustainability issues and submitted them for final decision making by the CSR Committee.
We will continuously improve our response to sustainability issues.
