We source 40 percent of the wood used to make our products from our own Sustainable Forestry Initiative® certified forests, 30 percent from other certified landowners, and 30 percent from noncertified landowners — typically small, family-owned forests. Whether the wood comes from a certified forest or not, it is important that all the wood used to make our products comes from legal, noncontroversial and responsible sources.   


It is our long-standing policy and practice to ensure we, and all our wood suppliers, comply with all laws, and that our procurement practices do not cause or encourage the harvesting of wood from controversial sources. We conduct risk assessments of our wood supply area, track our sources of wood, and operate a due diligence system to maintain compliance with domestic and international laws and avoid sourcing wood from controversial sources. We are also guided by our own Wood Procurement Policy and our associated Sustainable Forestry Policy.  


While avoiding illegal and controversial sources of wood is important, it is just a first step. That is why we certify all our wood product mills to the SFI Fiber Sourcing Standard, which helps us expand the practice of responsible forestry to noncertified forests.   

We monitor for patterns and trends related to how practices are being implemented in our wood supply area and actively promote the practices of sustainable forestry through outreach and education to landowners, loggers and communities. Some of the steps we take, such as requiring our suppliers to follow best management practices to protect water quality and use trained loggers in harvesting, help us verify that all the wood in our products is from responsible, legal and noncontroversial sources. We communicate this assurance to our customers by using the "SFI Certified Sourcing" label on our products, and we encourage you to look for this label the next time you are buying a wood product.  


Most of our wood comes from North American forests that are certified through third-party auditing to recognized forest management standards, such as SFI or the American Tree Farm System. We also promote the certification of family forest owners to ATFS by providing a purchasing preference for ATFS-certified wood.   

We hold Chain-of-Custody certification under the SFI and Programme for the Endorsement of Forest Certification (PEFC) standards at select mills. These programs allow us to provide customers with a verified claim that the wood products they buy from us come from certified, sustainably managed forests. Chain-of-custody is an accounting system that tracks wood fiber from a certified forest through the different stages of production to a customer’s own chain-of-custody program. This process ensures true traceability from forest to product.
