20 Popular Household Brands That are Behind Costco’s Kirkland Products

Costco’s in-store brand Kirkland Signature is used for any number of items, from food and drinks to household and cleaning items. One of the great Costco hacks is buying their high-quality in-house brand items.

But what you may not know is that these products aren’t necessarily made by Costco.

In some cases, the warehouse retailer actually pays for brand-name products made by brand-name companies that allow Costco to relabel them as Kirkland Signature.

So which big brands are behind your favorite Kirkland Signature products? Here are a few that may surprise you.

If you need aluminum foil for everyday household purposes or even for use at a restaurant or business, it might be a good idea to grab the bulk version from Costco.

The Kirkland Signature version actually says “Reynolds” on its label, which clearly confirms the connection between the warehouse retailer and the aluminum foil maker.

You need batteries for everything from game controllers to remotes and more. If you go to Costco, pick up some of their Kirkland Signature packs of batteries for your home, office, or anywhere else.

Those AA and AAA batteries are actually Duracell batteries under the Kirkland Signature labels.

Like Reynolds, another brand name that shares its label with Kirkland Signature is Jelly Belly. The flavorful jelly beans come in a 64-ounce jug with both logos right on the front, making the partnership between the two clear.

You may be surprised to know that Bumble Bee is the company supplying Kirkland Signature with tuna for Costco’s eight-pack of tins on the shelves.

Diapers can be a costly expense when you have little kids at home. Some parents may find it easy to buy diapers in bulk at Costco with their Kirkland Signature label.

Those diapers are made by Kimberly-Clark, which also makes Huggies. So, chances are that you’re paying less for a name-brand diaper.

That Kirkland Signature coffee you’re picking up for a morning pick-me-up might be Starbucks coffee with a different label, as it has been reported that Starbucks roasts some Kirkland coffees.

And in fact, both Starbucks and Costco have their headquarters located in the Seattle area.

Ocean Spray is another brand that shares its label with Kirkland Signature in the aisles of Costco.

When shopping at the warehouse retailer, check out the two-pack version of Ocean Spray’s cranberry juice with both retailers on the label.

The warehouse retailer’s version of the iconic cup includes Chinet’s name right on the front of its packaging.
