Kirkland Signature store brand products

Kirkland Signature is the exclusive private-label brand of Costco Wholesale Corporation. Introduced in 1995, the brand was named after the city of Kirkland, Washington, where Costco's headquarters were located at the time. The brand was created to provide a high-quality alternative to name-brand products at a lower price point, maintaining a reputation for value and reliability across hundreds of different product categories.

Manufacturing for Kirkland Signature is decentralized. Costco often partners with leading manufacturers—many of whom produce national brands—to create the Kirkland version under strict quality standards. Consequently, production occurs in various countries including the United States, Canada, Mexico, China, and Vietnam, depending on the specific item. Costco Wholesale Corporation remains the ultimate owner, managing the brand from its current international headquarters in Issaquah, Washington.
