New certification PEFC ST 2002:2020

UNITAN certified the new version of the PEFC ST 2002:2020 Chain of Custody of Forest and Tree Products standard, which guarantees that timber and non-timber forest products and all their derivatives come from legally, socially and sustainably managed forests, through a traceability process that links a forest-based product to a legally and sustainably managed forest, respecting social conditions and land traditions.

For responsible and sustainable chemistry

As part of our commitment to more environmentally friendly products through responsible chemistry, we have achieved Zero Discharge of Hazardous Chemicals (ZDHC) certification by accrediting our products after successfully completing the Chem-Check certification process. ZDHC is the world's first verified database of safer chemicals for the apparel and footwear industry. This certification ensures that our products comply with all requirements related to the elimination of hazardous chemical releases proposed in the Manufacturing Restricted Substances List (MRSL), version 2.0.
