Are you an Oregon Costco member who cares about responsibly sourcing products?
A proposed class action complaint alleges that Costco made misleading representations to members regarding its promises of ethical sourcing while concealing labor scandals and investigations tied to suppliers behind its popular Kirkland Signature products.
This page summarizes allegations in a filed complaint and publicly available case information. Costco may dispute the allegations and no court has determined that Costco violated the law. The proposed class has not been certified and the outcome of the litigation cannot be predicted.
The lawsuit alleges that Costco marketed its memberships and Kirkland Signature products by emphasizing ethical sourcing, supply-chain transparency, supplier oversight, and efforts to prohibit child and forced labor. According to the complaint, Costco’s promotional materials promise membership purchasers that Costco prohibits child and forced labor by its suppliers, and enforces standards requiring supply chain transparency. In addition, Costco tells members that it “control[s] every element” of Kirkland Signature items’ production, and that all items have fully traceable supply chains.
The plaintiffs allege that these representations were misleading because Costco’s actual sourcing systems allegedly do not provide the level of traceability, oversight, supplier visibility, or control that Costco describes to consumers. The lawsuit also alleges that Costco continued selling products connected to supply chains with documented child-labor or forced-labor concerns while continuing to market itself as a leader in responsible sourcing.
The lawsuit seeks to represent Oregon Costco members and asserts claims under Oregon’s Unlawful Trade Practices Act, as well as a claim for unjust enrichment.
The complaint alleges that Costco sells items, including Kirkland Signature items, obtained from opaque supply chains, in violation of its claim to understand the origins of its products. Because the products cannot be traced to their origins, the allegation is that Costco cannot enforce its labor standards.
An example product described in the complaint is cashews. The complaint alleges Costco sources its cashews from over a million small farmers across Africa and Asia. The complaint alleges that the nuts are sold and resold by middlemen, and that commingling makes tracing the nuts to the farm that produced them impossible. This is apparent from the fact that Kirkland Signature cashews list 14 countries of origin.

The plaintiffs allege that selling items obtained through opaque supply chains such as this is a violation of Costco’s pledge to have “direct insight in the entire supply chain” of Kirkland Signature products.
Second, the complaint alleges that Costco knew of reported child labor or forced labor concerns involving certain products or supply chains. The complaint cites the following sources in support of that allegation:
The lawsuit was filed by two Oregon Costco members. They will ask the court to appoint them as representatives of a class of all Oregon Costco members.
A class action is a lawsuit brought by one or more individuals on behalf of a larger group of people who allegedly suffered similar harm. The plaintiffs in this case seek to represent Oregon Costco members who fall within the class definition proposed in the complaint. The Court has not yet decided whether a class should be certified.
The complaint discusses a variety of products and product categories, including Kirkland Signature products and products containing ingredients such as cocoa, cashews, coffee, seafood, shrimp, dairy products, and pet food. The lawsuit does not challenge the safety of these products. Instead, it focuses on representations concerning sourcing practices, labor conditions, supply-chain transparency, and ethical sourcing.
The lawsuit seeks to represent Oregon consumers who purchased or renewed Costco memberships during the relevant time period identified in the complaint.
The Court has not certified a class and no action is required in response to this lawsuit at this time. This is general information, not legal advice.
If the Court certifies a class or important developments occur in the litigation, additional information will be posted on this page. Any notice to potential or certified class members will be provided as authorized or directed by the Court.
