Costco’s Kirkland Signature brand has earned a reputation for offering high-quality products at lower prices, leading shoppers to wonder whether some of their favorite name brands are secretly making them. While Costco doesn’t publicly disclose the manufacturer behind every Kirkland item, a handful of partnerships have been confirmed over the years, while others remain popular rumors.
Some partnerships are confirmed
One of the best-known examples is Kirkland Signature batteries, which are manufactured by Duracell. Costco and Duracell have both acknowledged the relationship, giving shoppers confidence that they’re buying a trusted product under a different label.
Kirkland Signature hearing aid batteries have also been made by Duracell, and several Kirkland coffee products have been produced in partnership with established coffee companies.
Coffee has some well-known connections
Starbucks has confirmed that it roasts certain Kirkland Signature coffee products, including some whole bean offerings sold at Costco. However, that doesn’t mean every Kirkland coffee product comes from Starbucks. Different blends may come from different suppliers depending on the product and region.
Not every rumor is true
Over the years, shoppers have speculated that everything from Kirkland olive oil to diapers, bottled water, and pet food is made by famous national brands. In many cases, there is little or no public evidence to support those claims.
Like many retailers, Costco works with a variety of manufacturers that may change over time. A product could be made by one supplier today and another in the future while still meeting Kirkland’s quality standards.
Why Kirkland products are often a good value
Rather than focusing on who manufactures each item, experts recommend evaluating the product itself. Kirkland Signature products often undergo extensive quality testing and are backed by Costco’s generous return policy, making them a popular choice for shoppers looking to save money without sacrificing quality.
While the mystery behind some Kirkland products continues to spark debate, one thing is clear: the warehouse retailer has built a private-label brand that millions of members trust.
