Commitment, Responsibility & Safety
SUMCO takes very seriously our responsibility to the communities in which we do business. The facilities we build, the way we operate and the community programs we undertake are all designed to ensure the safety and wellbeing of our employees and neighbors and the protection of the environment we share.
Our commitment to the environment is reflected in maintaining ISO 14001 certifications in all our manufacturing facilities.
SUMCO is a proud member of the Responsible Business Alliance (RBA) and confirms our commitment to environmental responsibility and ethical business practices.
