Managing our own forests sustainably is the first step in a responsible supply chain. But we don't just use our own wood fiber to make our products — and neither do the other companies that make products from trees.

Wood baskets (the fun term we use to describe the sources of wood supplying a mill) are made up of many landowners and forest types. Whether certified or not, it's important to us (and our customers) that all of the wood used to make our products comes from legal, responsible, and non-controversial sources.

More than 40 percent of our wood supply, in the form of logs and wood chips, comes from our own certified timberlands.

Close to 30 percent of our wood fiber comes from other certified forests — some from large landowners like us, lots from family landowners, and some from in between.

The remaining 30 percent of our wood supply comes from other legal, responsible sources. Most of this is supplied from small, family-owned forests.


Our entire wood fiber supply chain is certified to the SFI Fiber Sourcing Standard. This certification means we can use the "SFI Certified Sourcing" label on our products and lets our customers rest at night, knowing our products are from responsible, legal and non-controversial sources. As part of this certification, we are required to show we:

  • Engage in outreach and education with forest owners on sustainable forestry and best management practices.
  • Support scientific research to broaden the awareness of climate change impacts on forests, wildlife and biological diversity. 
  • Use and support best management practices to protect water quality.
  • Encourage landowners to use qualified logging and resource professionals. 
  • And more. Learn more about the Fiber Sourcing Standard on the SFI website

Additionally, to support more family forest owners on their journey of responsible, sustainable forest management, we have a purchasing preference for wood certified under the American Tree Farm System.


While all of our wood fiber comes from responsible sources, not all of it is certified. Chain of custody is an accounting system that tracks wood fiber through the different stages of production. It allows us to make claims about how much of our product comes from certified forests and how much comes from responsible sources, and then pass those credits (or claims) on to our customers. In addition to tracking certified and non-certified volumes, chain-of-custody standards require us to implement due-diligence systems (or risk assessments) to avoid non-certified wood fiber coming from illegal or irresponsible sources.

Our senior management team is committed to implementing chain of custody at selected sites and, while those sites are certified, maintaining chain-of-custody requirements in accordance with applicable standards. Learn more about the SFI Chain-of-Custody program and view our certificates.


It is our longstanding policy and practice to ensure we and our fiber suppliers comply with all laws and our procurement practices do not cause or encourage the destruction of forest areas at risk of loss due to illegal and unsustainable practices.

We do not knowingly purchase or use wood, wood fiber or products for distribution that originate from illegal logging. We conduct a due-diligence assessment and document the species and country of origin of our products on our Product Environmental Profiles. Our responsible fiber sourcing practices are guided by our Wood Procurement Policy.

We also maintain compliance with domestic and international laws related to the use of illegal timber, including the Lacey Act in the United States and the European Timber Regulation. The Lacey Act, amended in 2008, combats global trafficking in illegally taken wildlife, fish and plants, as well as illegally sourced wood and wood products. The European Timber Regulation was adopted by the European Union in 2013 and, like the Lacey Act, makes it unlawful to trade in wood from illegal sources.
