Supplier’s Code of Conduct

Sustainable development indicators including environment, labor practices, human rights, and social impacts have become the social focus in recent years.

Currently, apart from including these sustainable development indicators as part of the criteria for new supplier selection and supplier evaluation, we request new suppliers to sign related undertakings to comply with the following:

Labor and human rights No forced labor; no child labor; provision of due wages and benefits; guarantee for working hours and breaks; elimination of workplace sexual harassment, bully, and discrimination; and no conflict minerals.
Health and safety Measures required for occupational safety, emergency response, occupational health, protection against machinery injuries, public health, food and accommodation, and health and safety information.
Environment Operation permit; pollution prevention and resource conservation; hazardous substances; effluents; non-toxic solid waste; noise; exhaust emissions; product and service limitation; energy/resource consumption; and GHG emissions.
Ethics and integrity Ethical corporate management; respect for intellectual property rights; abidance by non-disclosure agreements; privacy protection; and avoidance of the conflict of interest.

Promotion of “Supplier’s Code of Conduct” (Supplier ESG Commitment)

In 2020, we added the Supplier CSR Commitment as an incentive. From 2022, the Supplier CSR Commitment is a prerequisite for priority assessment of all new suppliers.



By 2021, a total of 35 suppliers sent back the commitment. We already progressively requested suppliers to sign and abide by the commitment and revised the internal SOPs to add the commitment as one of the criteria for new supplier evaluation. Currently, new suppliers of major production materials are requested to sign the commitment. In the future, we will perform irregular onsite audits on the compliance with the commitment.

Currently, major feedstock suppliers and contractors Taiwan CPC and Dairen Chemical and partner CTCI have become our sound sustainable developer corporate suppliers. We adopt the “active risk management” policy to investigate suppliers with potential/negative impacts, including irregular visit of THAU BING to check for the offences or news regarding suppliers’ violation of the said terms and assess if such offences or news will bring negative or potential impacts (such as punishment or suspension order of competent authorities). In addition, we will take related risk controls and countermeasures for the potential raw materials supply crisis based on their offences.
