We create useful products made from trees, one of nature's most remarkable and renewable resources. In turn, it is our responsibility to ensure our products are safe and healthy for the people who make and use them, as well as for the environment. 

Our comprehensive Product Stewardship Policy outlines our commitment to considering environmental, health and safety implications for our products, from product design to end of life. Implementation of this policy reduces risk and liability, promotes compliance with applicable regulations, and helps deliver sustainable products to the marketplace. 

Our chemical management program works hand in hand with our product stewardship program, focusing companywide on reducing chemical risk through comprehensive management of chemicals approved for use, by reducing or eliminating the overall number of chemicals used in our operations, seeking less-hazardous substitutes for chemicals, and implementing their use across our company. We also use a companywide database — accessible to all employees — for all safety data sheets and labels for hazardous chemicals.

We’re also committed to sharing safety data sheets and corresponding labels for our products on this website to help ensure our customers, and our customers’ employees, handle and use our products safely.

Each safety data sheet listed below includes the corresponding labels on the last page of each PDF document.

Transparent Chemical Reporting

Annually, we publicly report the release of certain chemicals into the air, water and land under the U.S. Toxics Release Inventory (search for "Weyerhaeuser" under "Facility Name") and the Canadian National Pollutant Release Inventory (search for "Weyerhaeuser" in "Facility Name"). With rare exceptions, these are lawfully permitted releases that are made in a controlled fashion after steps have been taken to reduce the emissions and mitigate their effects. Both inventories mandate that we report total emissions without regard to changes in production levels.  

We also provide detailed information for our Kenora TimberStrand facility under Ontario's Toxic Substance Accounting program: 

  • Kenora TimberStrand Toxic Substance Accounting for 2018 and 2019
