The opportunity is bigger than most people realize
GM, Ford, and Stellantis collectively spent more than $3 billion with diverse suppliers in recent years. Ford alone reported $3.1 billion in diverse supplier spend in its 2023 sustainability data. These are not aspirational targets. They are actual disbursements tracked, audited, and reported annually.
All three were founding members of the Billion Dollar Roundtable, a group of corporations that each spend at least $1 billion annually with diverse suppliers. Automotive has been at the center of supplier diversity for 50 years, longer than any other sector except defense.
That longevity matters for one practical reason: the programs are institutionalized. GM has a full Supplier Diversity team with a dedicated portal, spend targets by category, and a development program for minority-owned businesses. Ford runs the Ford Supplier Diversity Development program and publishes annual spend data. Stellantis tracks spend through its North America Supplier Diversity office. These are not checkbox programs run by one person. They have staff, budgets, and procurement integration.
The realistic entry point for most diverse businesses is not a direct OEM contract. It is the Tier 2 or Tier 3 structure underneath.
How the automotive supply chain is layered
Tier 1 suppliers sell directly to the OEM. Think Bosch, Denso, Magna, Aptiv. These are companies with hundreds of millions in revenue, existing quality certifications like IATF 16949, and long-standing relationships. Breaking in at Tier 1 as a new supplier is possible, but rare for a small business.
Tier 2 suppliers sell to Tier 1s. This is where most diverse businesses realistically land first. A Tier 1 like Magna or Lear needs stampings, plastic components, chemicals, packaging, logistics services, and IT. They also face pressure from the OEMs to report their own diverse spend. That pressure creates demand for qualified diverse Tier 2 suppliers.
Tier 3 supplies to Tier 2. Commodity materials, sub-components, raw inputs. Lower contract values, lower barriers to entry, but also lower margins.
Non-manufacturing categories deserve specific mention. GM, Ford, and Stellantis all buy professional services: IT consulting, facilities management, marketing agencies, staffing, legal, and engineering services. A Black-owned IT firm or a woman-owned staffing agency can pursue OEM contracts directly without needing automotive manufacturing capabilities. NAICS code 541 (professional, scientific, and technical services) is a real path in.
Which certifications carry the most weight
NMSDC certification (MBE) is the baseline requirement for most automotive supplier diversity programs. GM, Ford, and Stellantis all require it or strongly prefer it for minority-owned businesses. Without it, you will not appear in the diversity spend tracking that procurement teams must report.
The Michigan Minority Supplier Development Council is the NMSDC affiliate that matters most in this sector. MMSDC is the most active affiliate nationally when measured by automotive industry engagement. It runs the annual Automotive Symposium, maintains relationships with all three Detroit OEMs, and facilitates introductions between certified MBEs and Tier 1 procurement staff. If your business is anywhere in the Midwest or sells to automotive, MMSDC certification (not just the national NMSDC certificate) gives you access to those specific relationships.
For women-owned businesses, WBENC certification is the equivalent standard. Ford and GM both track WBE spend separately and both participate in WBENC's annual Forum & Business Fair, where WBEs meet corporate procurement officers face to face.
SDVOSB and VOSB certifications matter less in automotive than in federal contracting, but Ford has a specific veteran supplier initiative and will track that spend if you have the certificate.
IATF 16949 is not a diversity certification. It is the quality management standard specific to automotive manufacturing. If you are selling manufactured parts, you will eventually need it. Tier 1 suppliers will ask for it before awarding significant volume. For professional services, it is irrelevant.
Named programs and where to find them
General Motors: GM's Supplier Diversity program is managed through their Supplier Diversity Development office. They run the annual Supplier Diversity Summit and maintain a searchable database of registered diverse suppliers. The entry point is registration on the GM Supplier Portal, followed by certification verification. GM also runs the "Minority Business Development" track within their supply chain development arm, which provides mentoring and capacity-building for smaller MBEs.
Ford Motor Company: Ford's Supplier Diversity Development program is one of the oldest in the industry. They publish an annual supplier diversity report with spend breakdowns by certification type (MBE, WBE, LGBTBE, DVBE). Ford participates in NMSDC's Corporate Plus program and actively recruits at MMSDC events. Their procurement teams are organized by commodity. Finding the right category manager matters more than a general introduction.
Stellantis: Stellantis (formed from the Fiat Chrysler and PSA merger in 2021) has continued the legacy FCA supplier diversity program through its North America Supplier Diversity office. They have a supplier registration portal and attend MMSDC events. Spend targets are less publicly disclosed than GM or Ford, but the program is active.
Toyota, Honda, Nissan, Hyundai/Kia: The Japanese and Korean transplants all have supplier diversity programs in the US, driven partly by government pressure and partly by community relations in their manufacturing states. Toyota's program is run out of its Plano, Texas headquarters. Honda's is managed from Marysville, Ohio. These are smaller programs than the Big Three but real. Honda has historically been strong on minority business development in Ohio through its relationship with the Ohio Minority Supplier Development Council.
Typical contract sizes and entry patterns
Professional services contracts with OEMs typically start in the $500K to $2M range for initial engagements. IT and staffing can be larger. Marketing and events can be smaller.
Manufacturing contracts vary by commodity. A stamping program for a specific part might run $300K to $1M annually for a small supplier. Packaging and indirect materials (MRO, office supplies, uniforms) often start smaller but are easier to win because procurement oversight is less intensive than for parts that go into the vehicle.
Tier 2 manufacturing contracts with large Tier 1s like Magna, Lear, or BorgWarner can range from $200K to several million annually depending on volume. These are more accessible than OEM-direct contracts.
Most diverse businesses enter through one of three paths: responding to a Tier 1 RFQ after being introduced through MMSDC; being identified by an OEM procurement officer at a conference; or winning a subcontract under a prime supplier who needs to report diverse spend. The third path is underused. Prime contractors at the OEM level actively need certified diverse subcontractors to hit their own supplier diversity metrics. Positioning yourself as a capable subcontract partner is a legitimate strategy.
Industry-specific barriers
Quality certification requirements: IATF 16949 costs time and money to achieve. A small manufacturer pursuing automotive business should budget 12 to 18 months and $30,000 to $80,000 for certification, depending on current quality systems. Starting this process before you have a contract in hand is the only way to be ready when an opportunity comes.
Long payment cycles: Automotive payment terms are notoriously slow. Net 60 to Net 90 is common. For a small supplier, this creates cash flow pressure on any contract above $200K. Factoring and supply chain finance programs exist, and several OEMs have early payment programs for diverse suppliers. Ask about them before signing.
Tooling and capital requirements: Manufacturing contracts often require upfront tooling investment that the supplier bears until reimbursed. This capital requirement screens out undercapitalized firms. Some NMSDC affiliates have lending partners, and several SBA programs cover tooling for government-adjacent contracts.
Relationship-dependent sourcing: Automotive procurement is heavily relationship-driven. Decisions made in formal RFQ processes are often pre-shaped by relationships built over years. This is not a fair system for new entrants. It is, however, the system. The practical counter to it is sustained conference presence, MMSDC membership, and direct outreach to Tier 1 supply chain managers, not just OEM procurement.
First steps for a new diverse business in automotive
First, get your NMSDC certification through your regional council. If you are in Michigan, Ohio, Indiana, or Illinois, apply through MMSDC. This takes 60 to 90 days from application to certificate.
Second, join MMSDC as a member, not just a certificate holder. Membership gets you into the Automotive Symposium, the matchmaking events, and the council's internal communications about OEM sourcing needs.
Third, identify your NAICS codes precisely. Automotive procurement staff search by commodity. If you are a staffing firm, 561320 is more useful than a generic services code. If you make stampings, 332119 or 332116. Get this right before registering on any supplier portal.
Fourth, register on the supplier portals. GM, Ford, and Stellantis each have separate portals. MMSDC maintains a directory that feeds some OEM systems. Register on all of them. This is table stakes.
Fifth, identify two or three Tier 1 suppliers in your commodity and contact their supplier diversity or purchasing teams directly. Magna, Lear, BorgWarner, Aptiv, and Flex-N-Gate all have supplier diversity initiatives. A direct conversation with a Tier 1 purchasing manager is often easier to get than a meeting at GM.
The automotive supply chain has real money flowing to diverse suppliers. Getting in requires certification, the right commodity alignment, and patient relationship-building. None of those three things are quick, but all of them are within reach.
