If you are searching for Kellogg's supplier diversity program in 2026, the first thing to know is that the Kellogg Company you have in mind no longer exists. It split in October 2023 into two public companies, and both of those have since been acquired. Most guides on this topic still point to portals and contacts from the old company, which is why so many suppliers hit dead ends. Here is the current map.
Who owns what now
Kellanova took the global snacking business: Pringles, Cheez-It, Pop-Tarts, Rice Krispies Treats, RXBAR, Eggo, MorningStar Farms, and Kellogg's international cereal brands. Mars completed its $36 billion acquisition of Kellanova on December 11, 2025. Kellanova's brands joined the Mars Snacking division, which is headquartered in Chicago.
WK Kellogg Co took the North American cereal business, headquartered in Battle Creek, Michigan. Ferrero completed its acquisition of WK Kellogg Co on September 26, 2025, paying $23.00 per share in cash. The company was delisted from the New York Stock Exchange and now operates as part of the Ferrero group, which says it plans to grow the cereal portfolio across the United States, Canada, and the Caribbean.
So "becoming a Kellogg supplier" now means choosing between two privately held food giants. Only one of them publishes a supplier diversity program.
Kellanova still runs a supplier diversity program
As of July 2026, Kellanova's supplier diversity program is alive on two live pages: the "Doing Business with Kellanova" page at kellanova.com and the supplier diversity section of its Better Days Promise site (betterdayspromise.kellanova.com/supplier-diversity, still carrying a 2026 copyright under Mars ownership).
The program's own words: Kellanova relies on "hundreds of incredible certified diverse ingredient, packaging, indirect services and co-manufacturing suppliers from around the world." It defines a diverse supplier as "a business that is at least 51% owned and operated by an individual or group that is part of a historically underrepresented or underserved group." The ownership categories it names are Aboriginal-owned, disability-owned, LGBTQ+-owned, minority-owned, veteran- and service-disabled-veteran-owned, and woman-owned businesses.
Those four sourcing areas (ingredients, packaging, indirect services, and co-manufacturing) are the honest signal of what you can sell them. If you supply food ingredients, flexible or corrugated packaging, contract manufacturing capacity, or indirect categories like logistics, facilities, marketing services, or IT, you fit the program's stated scope. If you sell something else, registering will not conjure demand.
What Kellanova does not publish: a spend goal, a diverse-spend percentage, a program manager's name, or a list of accepted certifying bodies. The pre-split Kellogg Company ranked in DiversityInc's top 10 for supplier diversity as recently as 2022; Kellanova's current pages carry no numbers at all. Treat any dollar target you see on a third-party site as stale.
Where to register
The entry point is the Doing Business with Kellanova page: kellanova.com/us/en/about-us/business-with-kellanova.html. Under "Interested in becoming a Kellanova supplier?", the registration link goes to a partner registration form on smart.gep.com. Kellanova runs new-supplier intake on GEP SMART, not Ariba or Coupa, so build your profile there once and it serves any other GEP-based buyer too.
Two other verified routes from the same page:
- kellanovapartnerengagement@kellanova.com is the published email for supplier questions, including questions about the Mars integration. A real inbox with a specific purpose beats a generic contact form.
- Existing Kellanova suppliers are directed to the Mars Supplier Gateway's "Better Together" section (supplier.mars.com/supplier-tools/supplier-better-together), which hosts supplier transition guides covering contacts, invoicing, purchase order validity, and contract status during the integration.
The Doing Business page also links Kellanova's Global Supplier Code of Conduct and its purchase order terms and conditions. Read both before you pitch; they define the baseline every supplier signs up to.
Which certifications matter
Since Kellanova names ownership categories but not certifying bodies, work backward from the word "certified" in its program language. The bodies that issue the certifications matching Kellanova's categories are:
- NMSDC for minority-owned businesses (MBE certification through your regional council)
- WBENC for women-owned businesses
- NGLCC for LGBTQ+-owned businesses
- Disability:IN for disability-owned businesses
- SBA VetCert for veteran-owned and service-disabled-veteran-owned businesses
- CCAB in Canada and Supply Nation in Australia for Aboriginal-owned businesses, which matters because Kellanova's program language is global
Self-attesting in a registration form is possible; holding a current third-party certification is what makes you countable when a corporate program reports diverse spend. Get certified first, then register, so your GEP profile is complete on day one.
WK Kellogg Co publishes no supplier diversity program
We checked the "Doing Business with WK Kellogg Co" page at wkkellogg.com in July 2026. It contains purchasing terms for North America and Mexico and the WKKC Supplier Code of Conduct. That is all. No supplier registration portal, no supplier diversity program, no procurement contact, no certification list.
That does not mean WK Kellogg Co buys nothing. A cereal business still purchases grain, packaging, co-manufacturing, and indirect services. It means there is no diverse-supplier front door. If WK Kellogg Co is your target, your route is the ordinary commercial one: identify the category owner, use the site's general contact channel, and pitch on capability and price. Ferrero's completion announcement said nothing about procurement or supplier programs, and Ferrero publishes no North American diverse-supplier registration route we could find.
The Mars wrinkle
One more thing before you plan around Kellanova's program. Mars' own supplier gateway once hosted a supplier diversity page at supplier.mars.com/supplier-diversity. When we checked on July 24, 2026, that URL returned a page-not-found while sibling pages on the same site loaded fine. The supplier-facing program Mars does publish today is size-based, not diversity-based: an SME registration questionnaire that grants standard payment terms to suppliers classified as small or medium enterprises.
Read that however you like; the practical takeaway is narrower. Kellanova's supplier diversity pages are still up seven months after the deal closed, but the integration is ongoing and Mars gets to decide what survives it. Register through the Kellanova route while it exists, complete the Mars SME registration if you qualify (better payment terms are worth a questionnaire regardless), and keep your certifications current so you are countable under whatever program shape emerges.
The short version
- Decide which company you are actually targeting: Kellanova (Mars) for snacks, frozen, and international cereal; WK Kellogg Co (Ferrero) for North American cereal.
- For Kellanova: get certified (NMSDC, WBENC, NGLCC, Disability:IN, or SBA VetCert), then register via the GEP SMART link on kellanova.com/us/en/about-us/business-with-kellanova.html.
- Email kellanovapartnerengagement@kellanova.com with a short, specific pitch: your category (ingredients, packaging, indirect, or co-manufacturing), your certification, and one proof point.
- If you qualify as a small or medium enterprise, complete the Mars SME registration at supplier.mars.com for standard payment terms.
- For WK Kellogg Co: there is no diversity program to join. Pitch the category owner through the general contact channel and compete on capability.
The split confused this landscape badly, and the acquisitions confused it further. But the facts as of mid-2026 are simple: one live program, one working portal, one published email. Use all three.
