UPM's Kaukas and Kymi mills have received the FSC certificates for their chain of custodies. Kymi's certificate was granted on May 7, 2007 and Kaukas' certificate is valid from May 10, 2007.
The certificates ensure that FSC requirements have been implemented to mills management systems, thus also share of FSC certified fibre in their products can be officially reported. Both mills use FSC certified wood originating from Russia and Estonia where UPM's forestry and wood sourcing operations have already earlier been awarded FSC certified chain of custody. Certificates also guarantee that mills use only FSC controlled wood.
The chain of custodies of the mills have PEFC certificates since 2003.
