What is chain of custody certification for timber?

Chain of custody (CoC) is a certification system that tracks timber products from the certified forest through every stage of processing, manufacturing, and distribution to the final customer. It provides documented evidence that timber sold as 'certified' genuinely originates from responsibly managed forests.

Chain of custody (CoC) is a certification system that tracks timber products from the certified forest through every stage of processing, manufacturing, and distribution to the final customer. It provides documented evidence that timber sold as 'certified' genuinely originates from responsibly managed forests. Every organisation in the supply chain that takes ownership of the timber (sawmill, manufacturer, wholesaler, merchant, retailer) must hold its own CoC certificate to make certified claims. Without CoC, timber cannot be sold as FSC or PEFC certified, regardless of its actual forest origin.
