Companies that Make the Brands You Find at Costco
It wasn’t until there was a recall on Diamond Pet Foods a few years ago that I learned that other companies were making Costco brands. You see, in that recall notice that Diamond put out, it included Costco’s Kirkland Signature. Who knew? Well, it turns out that Costco partners with well-known companies to make some of the most popular Kirkland Signature products it sells.

Well-known names behind Costco brands

It’s not like Costco hides these partnerships from shoppers. Just take a look at the signage at your local Costco store or even on the Costco website. For example, when I was shopping at Costco and looking at buying coffee, I noticed the Starbucks name. It was on the price tag on the shelf as well as the bag of Kirkland Signature House Blend coffee.
I have it on good authority that the Kirkland Signature spirits that Costco sells? Well, when it comes to vodka, there is a very good chance that either Tito’s or Grey Goose made that spirit for the store. And chances are you will pay a lot less for that brand than you would elsewhere. In fact, in my cases when you shop at Costco, you will discover that Kirkland products are big brands in disguise.
Why it’s smart to buy store brands
This is good information to have. Why? Because savvy shoppers know creative ways to save money, such as shopping at thrift stores. Another popular money saver is buying store brands.
With prices on the rise, it’s one of the reasons that companies with private label products and the stores continue to make them. What’s so special about big names making products for Costco? Basically, you can buy the equivalent of brand-name items but at generic prices. And they’re worth it. For instance, when Nicole Weatherford of Everyday Thrifty compared Costco vs Walmart vs Aldi, Costco came out on top.
Costco Membership Deal via Groupon
The best deal on a Costco Membership right now is through Groupon. When you sign up, you’ll get your one-year membership plus a $40 Costco Digital Shop Card for free.

Also, you can avoid the lines at your Costco location by signing up for this Groupon Costco deal. This was the crowd at the new Costco in Maine near where I live. Yikes!

Here’s the lowdown on filling up at Costco gas stations.
Costco brands and products
The next time you’re in Costco, look for these Kirkland brand products. Then, you can pat yourself on the back for knowing which company really made these Costco brands.
Costco Kirkland diapers
Who manufacturers Costco Kirkland diapers? Why it is Kimberly-Clark, which makes Huggies diapers, among other consumer goods. In case you didn’t know, Costco also sells Huggies. Not surprisingly, though, the Kirkland brand is cheaper by about two cents per diaper. So when you’re looking at the Costco brand of pull ups, chances are they are the same or similar to the Huggies brand of pull ups.

That might now seem like a lot of money. However, when you’re buying a pack of 200+ diapers in a single trip, that can add up. Parents Magazine says that a baby can go through up to 3,000 diapers in their first year. So, you do the math.
Costco brand dog food

When we adopted our dog Oscar in 2015, he came with a bag of Costco brand dog food. It was Kirkland Signature Nature’s Domain food, which I now know that Diamond Foods makes for the store. As I mentioned in the introduction to this article, it was only when Diamond Foods had a recall that I got clued into the fact that another company was making the Kirkland brand dog food at Costco.
Costco tuna is Bumblebee
According to CNN, in 2003 Costco started selling Kirkland brand tuna that is from Bumblebee. They continue to sell it today–even displaying it right next to brand-name Bumblebee tuna.

Kirkland Signature wipes
“My children have all had super sensitive skin as babies,” says Siobhan Borland of Mimosas and Motherhood, “and the Kirkland sensitive baby wipes are one of the few options that don’t irritate their skin.”

She wasn’t aware that another company, called Nice Pac, makes these wipes. That company also makes Costco flushable wipes and cleaning wipes. They’re also responsible for Nice N Clean wipes and Grime Boss (sold at Home Depot). Plus, they’ve received awards for their work with Costco.
Costco Coffee Brands: Genuine Keurig K Cups
Speaking of coffee, you can buy Kirkland Signature coffee k cups in bulk and feel confident that they’ll work in your Keurig machine. That’s because Keurig is Costco’s partner in making these coffee pods. That’s why it says, right on the box, “Keurig Genuine K Cup Pods.”

Here are tips on how to make cold brew coffee.
Kirkland organic granola

Nature’s Path Organic is responsible for making the Kirkland Granola. You may have seen the brand in places other than Costco. For example, you can buy Nature’s Path Organic at the following retailers as well:
Here are some low carb yet sweet breakfast recipes.
Stearns and Foster Costco mattresses
Some of the name-brand mattresses you can buy at Costco include Casper and Tempurpedic. Costco sells them under their original brand names. However, there is also a Kirkland Signature mattress to consider. Stearns and Fosters is the manufacturer.

Reynolds foil
When you pick up one of those mega-boxes of Kirkland aluminum foil at Costco, take a closer look at the box. It says Reynolds foil right on the label.

Jelly Belly jelly beans
If you’re particular about your jelly bean brands, you don’t have to worry about buying the generic version at Costco. The Kirkland brand is actually from Jelly Belly. This article on factory tours for families includes the Jelly Belly factory in California.
Sunsweet prunes
When you buy Kirkland Signature dried plums, aka prunes, you’ll see that they’re made in conjunction with the Sunsweet brand.

PaperChef parchment paper
Another baking necessity is the Kirkland parchment paper, which the PaperChef culinary company makes for Costco.
Big Red Cups by Chinet
You won’t find red solo cups at Costco. However, you will find something called the Big Red Cups from Kirkland Signature. And right under the Kirkland Signature logo, you’ll see it says Chinet, the company that makes the cups on Costco’s behalf.

Ocean Spray cranberry juice
You’re not getting generic and perhaps iffy cranberry juice when you purchase the Kirkland brand at Costco. That’s because, like the Chinet cups I just mentioned, you’ll see Ocean Spray right on the label, under the Kirkland name. So, you know who makes it.

Costco brand laundry products
There are rumors that the liquid laundry detergent in Kirkland containers is Persil laundry detergent. That’s yet unconfirmed. Others, like Kim Rowley Lohrberg of the SavingK blog, have hypothesized that Costco dryer sheets were the same as Bounce. Unfortunately, there is no evidence to support that either.
Plus, the article “The Secret Weapon Behind Costco’s Success” explains why Procter and Gamble (which makes Bounce dryer sheets among other products) does not make Costco’s store brand diapers. It seems that P&G turned down Costco’s request way back when, because it is not in the business of doing private label deals. So, Kimberly-Clark got the gig instead.
This is all good information to have, as Costco continues to open more stores across the country, including the first Costco in Maine which opened in 2023.
