As a Responsible Care® company, Trinseo recognizes the importance of selecting suppliers based upon their commitment to sustainability, Quality, Responsible Care, codes of conduct and regulatory compliance.

Trinseo continually updates its vendor selection criteria for raw materials and logistics suppliers to include these components. Trinseo is committed to purchasing from Responsible Care® companies whenever possible, and we require suppliers to comply with our comprehensive Supplier Code of Conduct, which was introduced in 2015. 

Trinseo uses a Purchasing Scorecard that evaluates suppliers on a wide range of criteria including quality, cost, and sustainability. Metrics in the sustainability category include hazard awareness training, ongoing tracking of EH&S performance, and the use of third-party environmental management programs such as ISO or Responsible Care.
Trinseo has issued a statement on Conflict Minerals and a commitment to the California Transparency in Supply Chains Act, which addresses human trafficking and labor rights.
