Kirkland Signature Diapers

Kirkland Signature diapers are the private-label brand of Costco Wholesale. These diapers are widely recognized for their high quality, which many consumers compare to national brands. The product is primarily manufactured by Kimberly-Clark, the same company behind the Huggies brand, which allows Costco to offer premium materials and leak-protection technology at a competitive price point.

Originally launched in the United States, the brand has expanded globally alongside Costco's retail footprint. While the majority of the production takes place in the United States to serve the North American market, manufacturing may occur in other regions depending on the local supply chain of the manufacturing partner and the specific market's distribution needs.
