Strong ethics are deeply rooted in our culture at Weyerhaeuser, and for more than 120 years we've earned a reputation for conducting business honestly, fairly and with integrity. In 2022 we celebrated being recognized for the 13th time as one of the World's Most Ethical Companies® by Ethisphere Institute, a global leader in defining and advancing the standards of ethical business practices. This honor acknowledges our strong culture of integrity and compliance at every level of the company.   

Our Ethics and Business Conduct program includes our long-established Code of Ethics, regular employee ethics training, confidential resources to report ethics concerns or questions, and clear expectations for suppliers.   


First established in 1976 and now in its ninth edition, our Code of Ethics clearly outlines our expectations for ethical business conduct within Weyerhaeuser. With translations in multiple languages, our Code of Ethics is a resource for all employees on ethical decision-making and provides guidance on topics such as conflicts of interest, antitrust and competition laws, international business conduct, preventing harassment and discrimination, human rights, health and safety, and much more.  


We provide comprehensive ethics training to all employees on a regular basis, and we also ensure a certificate of compliance is completed by employees in key roles. In 2019, we updated our ethics and compliance training modules and refreshed our enterprise risk assessment, and in 2020, we updated our overall ethics training itself.  


To report concerns or ask questions about potential violations of our Code of Ethics, company policies or the law, anyone can confidentially and anonymously call our EthicsLine at 800-716-3488 or use Weyerhaeuser EthicsOnline. These resources are managed by an independent company and are available in multiple languages 24 hours a day, seven days a week. The resulting confidential case reports are quickly referred to our Ethics and Business Conduct office. Concerns about accounting, audit matters or internal controls can also be submitted directly to the chair of our board of directors' Audit Committee by contacting our corporate secretary

We use a variety of processes to ensure both our company and our supply chain are responsibly managed.  

Safety comes first 

We expect our suppliers to provide a safe work environment; comply with and maintain policies consistent with our applicable environmental, health and safety laws; and act in accordance with our Supplier Code of Ethics when working for us. 

Our standard terms of purchase require suppliers to comply with all applicable laws, including safety, labor and employment laws.  

Our suppliers must become familiar, comply with and maintain policies consistent with our environmental, health and safety requirements.  

Performance and diversity 

We establish robust supply chains for our products and work to enhance their performance. We also recognize that talent and innovation are found everywhere in our communities and seek diversity among our suppliers.  

Risk and value 

To mitigate risk and create the best possible value, our procurement programs are committed to reducing cost, enhancing supply chain resilience, and selecting suppliers that are aligned with our needs and values. We also consider other factors, such as administrative costs, ongoing technical support and maintenance, and risks of use and alternatives.  

Human rights

Our Human Rights Policy is guided by the United Nations' Universal Declaration of Human Rights and is part of our Code of Ethics. Although we do not have major operations in countries or locations where we believe human rights are being violated or are at risk, we have implemented policies and programs to ensure these rights are protected. Our human rights program is periodically reviewed against the Ruggie Framework to identify any areas of improvement, and we report any major concerns to our board of directors. The policy states our commitment to respecting human rights in our company and in our supply chain.  

The California Transparency in Supply Chains Act of 2010 requires retailers and manufacturers “to publicly disclose their efforts to eradicate slavery and human trafficking from their direct supply chains." Since our raw materials are sourced and all our manufacturing activities are conducted in North America, we believe the risk of slavery or human trafficking in our supply chain is very low.  

Noncontroversial wood fiber

All our manufacturing facilities are certified to the Sustainable Forestry Initiative® Fiber Sourcing Standard, which ensures we avoid controversial sources of wood fiber. We have processes to assess the risk of fiber sourcing from countries without effective laws addressing workers’ health and safety, fair labor practices, Indigenous people's rights, anti-discrimination and anti-harassment measures, prevailing wages and workers’ right to organize. Select facilities are also certified to the SFI and PEFC chain-of-custody standards, which require we are at low risk of controversial sources for fiber, including countries with health and labor issues.  

Additional assessment of foreign suppliers 

As a member of the Customs-Trade Partnership Against Terrorism, we conduct risk assessments of our foreign suppliers. We gather information to assess whether security vulnerabilities may create a high-risk supply chain and, if indicated, develop a map of the supplier’s cargo flow and business partners. If needed, we work with our suppliers to develop a corrective action plan to address any gaps or vulnerabilities, and we periodically audit suppliers and action plans.  


A supplier’s failure to comply with the above expectations could result in termination of the supplier relationship. Employees who fail to comply with these expectations are subject to disciplinary action, up to and including termination of employment.
