Who Really Makes Costco's Kirkland Products? You May Be Surprised

Here's why Kirkland is Costco's secret weapon!

Kirkland Signature is the private label of Costco that brought in close to $60 billion in sales for the warehouse giant in 2021, about a quarter of its sales during its last fiscal year. Since its launch in 1995, Kirkland has expanded from 30 to 351 products. Named after the company's original Washington State headquarters, Kirkland was created as an umbrella for Costco's different private labels. Since then, it has become one of the most recognizable brands in the U.S.

But who makes these products? While some are made exclusively for Costco and sold under the Kirkland Signature label, many of them are actually made by name-brand manufacturers who also produce their own branded versions of the same product. These companies will often agree to produce an exclusive version for Costco that meets its strict standards for quality and price point. The only difference? The distinct black, red, and white label and packaging and a lower price. In fact, prices are typically 20% lower than comparative brands, helping you stay on budget.
