Supply Chain

Westlake Vinnolit’s declared aim is to ensure compliance with environmental and social standards within the supply chain. This includes, in particular, respect for human rights as well as the responsible procurement and handling of raw materials.

We encourage and promote an open dialogue with all our stakeholders and this is also reflected in our Supplier Code of Conduct.

The most important prerequisites for compliance with the social and ecological due diligence obligations are achieving transparency in our supply chains and the traceability of goods flows.

If we identify risks at our suppliers, we counter these with preventive and remedial measures.

We take violations of our standards and principles along the supply chain very seriously. If there are any complaints or indications in this regard, please report them to us HERE immediately.
