Integrity is one of our company's core values. This means we hold ourselves to the highest standards of ethical conduct and always strive to do the right thing in the right way. Our goal is to earn trust through honest action.

Our first code of ethics was issued in 1976 and is currently in its ninth edition, with translations in multiple languages. It explains the standards of conduct we are expected to follow, including antitrust and competition laws, anti-bribery laws, conflicts of interest, intellectual property, safety and health, human rights, international business conduct and more. Our robust program ensures our employees and leaders understand and follow our code of ethics and model and promote ethical behavior.


We make ongoing improvements to our program, including revising our code of ethics, providing ethics training to all employees on a regular basis, and ensuring a certificate of compliance is completed by employees in certain roles. Our Ethics and Business Conduct Charter describes how our program is managed internally, including information on governance and oversight. In 2015, we rolled out updated anti-bribery training, refreshed our U.S. legal risk assessment and completed an international legal risk assessment.


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 at CorporateSecretary@weyerhaeuser.com.

Our Human Rights Policy, guided by the United Nations Universal Declaration of Human Rights, is referenced in our code of ethics. Although we do not have major operations in countries or locations where human rights — including freedom of association, child labor and forced labor — are at risk, we have implemented policies and programs to ensure human rights are protected. We have assessed and enhanced our existing policies, practices and programs. We track human rights concerns and report any major concerns to our board of directors.

We have reviewed our human rights program against the Ruggie Framework and identified any due-diligence items, including reinforcing our Supplier Code of Ethics and Human Rights Policy with our procurement staff, who are most likely to intersect with potential human rights concerns. We updated our code of ethics, including the human rights section, and we also recently added human rights information to our anti-bribery training.


We use a variety of processes to ensure our supply chains are responsibly managed.


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. 

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 the right suppliers 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.



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 the majority of our raw materials are sourced — and almost all our manufacturing activities are conducted — in North America, we believe the risk of slavery or human trafficking in our supply chain is low. Nonetheless, we have a variety of mechanisms in place to assess and reduce these risks in our supply chain. 

Expectations of suppliers

The standard terms of purchase that apply to our U.S., Canadian and European-based supply contracts require suppliers to comply with all applicable laws, including safety, labor and employment laws. Our suppliers must become familiar, comply and maintain policies consistent with our environmental, health and safety requirements.

Human rights

Our human rights policy prohibits the use of “chattel slaves, forced labor, bonded laborers or coerced prison labor,” and we expect that our suppliers will maintain fair working conditions and freedom of engagement and association.

Third-party certification of fiber sourcing

All of our manufacturing facilities are certified to the Sustainable Forestry Initiative® Certified Sourcing Standard, which includes Objective 13: avoidance of controversial sources, including fiber sourced from areas without effective social laws. This objective requires companies that source forest-based raw material from outside the U.S. and Canada to have a process to assess the risk of fiber sourcing occurring in 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. Our facilities are also certified to the SFI, PEFC, FSCTM chain-of-custody standards and FSCTM controlled wood standard, which include requirements for demonstrating that we are at low risk of sourcing from “controversial sources," including 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 will 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.

Transparency and disclosure

We publicly report on our progress toward meeting our long-term sustainability goals annually. We also support the use of internationally accepted standards that give stakeholders an objective, third-party analysis to judge whether a company is following responsible, sustainable forestry practices and effectively managing its environmental impacts.
