Complaints Channel

Sigdo Koppers seeks to maintain a work environment and business practices consistent with its business principles, making available to its colaborators, clients, suppliers, shareholders and the community at large a complaints channel, which can be anonymous or direct. These may be related to breaches of ethical standards, conflicts of interest, regulation violations or inappropriate conduct that require the attention of top Management and the Board of the company.

All complaints received will be analyzed promptly and confidentially. We appreciate the responsible use of this channel, and well as your cooperation in complying with the principles and values established at Sigdo Koppers.
