  • Costco Disclosure Regarding Human Trafficking and Anti-Slavery

    Costco has a supplier Code of Conduct which prohibits human rights abuses in our supply chain. Practices such as human trafficking, physical abuse of workers, restricting workers' freedom of movement, confiscation of passports and worker documentation, unsafe work environments, failure to pay adequate wages, excessive and/or forced overtime, illegal child labor, and many other aspects of worker welfare are addressed by the Code. Our suppliers contractually agree to follow the Code and to ensure that their sub-suppliers also comply. We may acknowledge and accept a supplier's code as equivalent to our Code.

    To evaluate compliance, we arrange for the audit of facilities of selected suppliers, with an emphasis on suppliers of private label merchandise and when Costco Wholesale is the importer. Audits are performed by independent third-party auditors who specialize in social responsibility audits. While we retain the right to conduct unannounced audits, as a practical matter, some minimum amount of notice is given to comply with security concerns and to allow the supplier to collect records that are reviewed during the audit.

    If we discover a violation of our Code of Conduct, we respond in a manner commensurate with the nature and extent of the violation. "Critical violations" are considered serious enough to require immediate and decisive remedial action and may result in the termination of the business relationship. For less serious violations, we allow the supplier reasonable time to develop and implement a plan for remediation. In those instances we conduct follow-up audits to monitor progress.

    In general, we prefer working with the supplier to correct Code violations rather than immediately terminating the relationship. Termination is unlikely to correct the underlying issue and may cause further hardship to workers and their families who depend upon the employment. However, if the supplier fails to make satisfactory progress toward improvement, we will cease our business relationship with that supplier.

    Members of Costco's buying team who manage a supplier relationship will continue to be provided with in-person and online training. The training covers the Code of Conduct and its importance to our business and to the workers who produce the merchandise we sell. We encourage anyone who is aware of violations of the law or our Code to notify their management, our Code of Conduct Compliance team or utilize Costco’s whistleblower site:
