Cummins Inc. is one of the more transparent Fortune 500 companies when it comes to supplier diversity. The Columbus, Indiana-based engine and power technology company publishes annual ESG reports with supplier diversity spend data, names the certifications it recognizes, and runs a dedicated program with a named internal owner. If you have the right certifications and a product or service that fits their supply chain, there is a clear path in.
Here is what you need to know before you submit your first registration.
The Cummins Supplier Diversity program
Cummins calls its program the Supplier Diversity & Inclusion initiative, operated under its global procurement function. The company is a corporate member of both NMSDC (National Minority Supplier Development Council) and WBENC (Women's Business Enterprise National Council), which means its supplier diversity team attends conferences run by both organizations and actively works their affiliate networks.
Cummins does not publish a single public spend target the way some companies do (e.g., "15% of addressable spend"), but its annual ESG reports include year-over-year diverse supplier spend figures. In recent reports, the company has cited diverse spend in the hundreds of millions of dollars annually across its North American supply base. For 2022, Cummins reported over $800 million in diverse supplier spend. That number gives you a sense of scale: this is not a checkbox program.
The program covers Tier 1 direct and indirect spend. Direct spend means components and raw materials that go into Cummins products. Indirect spend covers the services and supplies the company buys to run its operations: facilities, IT, marketing, logistics, and professional services.
Certifications Cummins recognizes
Cummins recognizes the following certifications in its supplier diversity program:
- MBE (Minority Business Enterprise) — certified by an NMSDC regional affiliate
- WBE (Women's Business Enterprise) — certified by WBENC or a WBENC regional partner organization (WPO)
- WOSB (Women-Owned Small Business) — federal SBA certification
- SDVOSB (Service-Disabled Veteran-Owned Small Business) — VA/SBA certification
- VOSB (Veteran-Owned Small Business)
- LGBTBE (LGBT Business Enterprise) — certified by NGLCC
- SBE (Small Business Enterprise) — state or local certifications
- DBE (Disadvantaged Business Enterprise) — USDOT certification, relevant for any supplier serving transportation infrastructure projects
If you do not yet hold one of these certifications, your MBE or WBE certification is the highest-value starting point given Cummins's NMSDC and WBENC membership. Both certifications open doors at hundreds of other corporations simultaneously, so the investment is not Cummins-specific.
Where to register
Cummins uses Coupa Supplier Portal (CSP) as its primary vendor onboarding and management system. New diverse suppliers register at supplier.cummins.com, which redirects to the Coupa-hosted profile page.
Steps in the registration process:
- Go to supplier.cummins.com and click "Register as a supplier."
- Create a Coupa supplier account (free) if you do not already have one.
- Complete your company profile: legal name, DUNS/UEI number, certifications, NAICS codes, commodity categories, and diversity status.
- Upload your diversity certificate (NMSDC, WBENC, SBA letter, or equivalent).
- Submit the profile for review.
A few practical notes: Coupa profiles are searchable by Cummins commodity managers once approved, so the quality of your commodity and capability description matters. Use the NAICS codes that most precisely match your work; do not stuff unrelated codes. Your diversity certificate must be current — if it expired, renew before registering.
Cummins also maintains a Supplier Diversity contact email (supplierdiversity@cummins.com based on prior public disclosures) for direct inquiries. Use it sparingly and only after you have completed the portal registration.
Product and service categories Cummins sources from diverse suppliers
Cummins manufactures diesel, natural gas, and alternative fuel engines, filtration systems, power generation equipment, and turbochargers. Its supply base is accordingly heavy in:
Direct/manufacturing categories: - Metal components and fabrication (castings, forgings, machined parts) - Electrical components and wire harness assemblies - Filtration media and materials - Plastics, rubber, and sealing components - Packaging materials
Indirect/services categories: - IT services and software - Facilities management and maintenance - Logistics and transportation - Marketing, communications, and print - Legal, accounting, and HR consulting - Staffing and contingent labor - Engineering and technical services
The indirect categories are where most diverse professional services firms get their first contract. If you run an engineering consultancy, a staffing agency, a logistics firm, or a marketing agency, Cummins buys all of those at scale. You do not need to manufacture engine parts to participate.
Industry events where you can meet Cummins procurement staff
Cummins's supplier diversity team is active at a predictable set of events each year. Attending these with a clear pitch is the most direct way to get a conversation.
NMSDC Annual Conference — typically held in October. Cummins sends procurement and supplier diversity staff. The conference includes a matchmaking/business opportunity exchange where you can book 10-minute meetings with corporate buyers. Register through NMSDC.org.
WBENC National Conference & Business Fair — held in June. WBENC's largest annual event. Cummins is a corporate member and typically exhibits. The business fair has a structured matchmaking component.
NMSDC regional affiliate events — Cummins facilities are concentrated in Indiana, Ohio, Minnesota, and North Carolina. The regional NMSDC affiliates in those areas (e.g., Minority Business Opportunity Committee in Indiana, Great Lakes MSDC in Michigan/Ohio) hold matchmaking events where Cummins participates locally.
Indiana Minority Supplier Development Council (IMSDC) — given Cummins's Columbus HQ, the IMSDC is the most direct local channel. Annual awards gala and matchmaking events bring Cummins procurement leads within reach.
To get a meeting at any of these events: register early (matchmaking slots fill fast), bring a one-page capability statement with your NAICS codes and diversity certification number, and state clearly what you sell and to whom you have sold it before. Procurement staff at these events are looking for suppliers ready to quote, not suppliers still figuring out their pitch.
Realistic timeline and first steps
Assume 6 to 18 months from first contact to first purchase order, depending on the category and whether you are a direct or indirect supplier. Direct manufacturing suppliers face qualification requirements (PPAP, IATF 16949 or similar quality standards) that extend timelines. Indirect suppliers can move faster once procurement identifies a need.
A realistic sequence:
Months 1-2: Obtain or renew your diversity certification. If you are MBE-eligible, start the NMSDC regional affiliate application immediately — processing takes 8 to 16 weeks at most affiliates.
Month 2: Register on the Coupa Supplier Portal at supplier.cummins.com. Complete the profile fully. Upload your certificate.
Months 3-6: Identify the next NMSDC or WBENC event where Cummins will be present. Register for matchmaking. Prepare a one-page capability statement: your certifications, NAICS codes, three to five reference clients, and what problem you solve.
Months 6-12: Follow up with any procurement contacts from events. Ask specifically about upcoming RFQs or vendor consolidation reviews in your category. Cummins runs annual sourcing cycles for most indirect categories; timing your outreach to align with those cycles increases your odds.
Month 12+: If you have not received a PO but have an active profile and event relationships, request a supplier development conversation through the supplier diversity team. These conversations are intended to help suppliers understand what gaps remain before they can be awarded business.
A few things that slow suppliers down: expired certifications, incomplete Coupa profiles, NAICS codes that do not match what procurement is actually buying, and capability statements that describe what you do rather than what you have delivered. Fix those before your first event.
Cummins is not an easy account to break into on a cold approach. It rewards suppliers who show up at the right conferences, hold current certifications, and can cite prior work in adjacent manufacturing or industrial supply chains. The process is slow but it is transparent. The annual ESG reporting means you can track their stated commitments year over year and hold them to specifics — which is more than most companies offer.
