Responsible Sourcing and Supply Chain Transparency

GTP is committed to ethical business practices, compliance with laws and respect for human rights, and we only do business with customers and suppliers that respect human rights and that share our commitment to compliance with the law and ethical business practices.

We exercise due diligence to ensure socially and environmentally responsible sourcing of raw materials in our supply chain. Human rights abuses of any kind, including child labor and any form of forced labor, are expressly prohibited in our Code of Conduct, Supplier Policy and Raw Materials Supply Chain Policy.
