Fiber Sourcing

The majority, more than 60 percent, of our wood supply comes from certified forests, both from our own timberlands and other certified forests. The remainder comes from small, non-certified forests, where we spend time educating and promoting the implementation of sustainable forest management practices. We are committed to responsibly sourcing materials contained in the products we manufacture.

In North America, we promote responsible forestry by requiring forest landowners from whom we buy wood fiber to use best management practices and qualified loggers during harvest. We provide information on sustainable forest management to all of our wood suppliers.

In the United States, two-thirds of commercial forest land is owned by 10 million individuals and families. We support two programs to fill this gap:

First, we have a purchasing preference for wood certified under the American Tree Farm System, the oldest and most widely adopted program in the world targeted at family forest owners. We actively work to bring landowners near our mills into the Tree Farm system.

Second, the Sustainable Forestry Initiative’s certified sourcing program is strong in promoting sustainable forest practices on uncertified lands. Our manufacturing facilities maintain certification to SFI’s Fiber Sourcing Standard. Under this program, we are required to:

  • Use loggers trained under SFI-supported programs
  • Engage in outreach and education with forest owners on sustainable forestry practices
  • Support scientific research on sustainable forestry
  • Ensure our suppliers use best management practices, such as leaving buffers along streams, building good roads, and using the right equipment and timing to protect soil


Through its fiber-sourcing standard, the SFI program stands apart from other independent forest certification programs by addressing the fact that all forest landowners — certified or not — play a critical role in the long-term health and sustainability of forests.

Since nearly 90 percent of the world’s forests are not certified, it's important to us to show that the uncertified raw material in our supply chain comes from legal and responsible sources. To demonstrate this, we certify all our manufacturing facilities and label all the forest products we produce in North America to the SFI Fiber Sourcing Standard. By certifying our manufacturing facilities to this standard, we demonstrate to our customers that we work with all of our suppliers — the majority of whom are family forest owners — to encourage broader implementation of sustainable forest management practices.

Understanding our supply chain ensures that we maintain compliance with domestic and international laws related to the use of illegal timber:

  • Lacey Act: in 2008, the United States amended the Lacey Act, a law combating global trafficking in illegally taken wildlife, fish and plants, and illegally sourced wood and wood products.
  • European Timber Regulation: in 2013, the European Union adopted its Timber Regulation which, like the Lacey Act, makes it unlawful to trade in wood from illegal sources.

It is our longstanding policy to ensure we and our fiber suppliers comply with all laws and our 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 due diligence 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.
