San Antonio, Texas
ISO 9001 consulting for the San Antonio supplier base.
A $3.6 billion expansion is pulling a large supplier base through a four-year transition. Here is what is actually published about the requirements, what is not, and the two standards here we do not offer.
We work in the Kansas City metro. Engagements here run remotely, with on-site visits at the points where being in the building changes the outcome — gap analysis, internal audit, and the certification audits themselves. We do not maintain an office in this market and would rather say so than imply otherwise.
What is published, and what is guesswork
In July 2026 Toyota announced a $3.6 billion expansion and 2,000 new jobs at its San Antonio plant — a second assembly line, roughly 2.5 million additional square feet, and a model transition running over four years. Site employment goes from around 4,000 toward about 6,000 by 2030, and the announcement references 23 suppliers already on site.
So a large local supplier base is about to be pulled through a multi-year transition, and the obvious question is which quality standard that requires.
Here is the honest answer, and it is shorter than most pages will give you. Toyota does not publish customer-specific requirements through the International Automotive Task Force — the IATF's own published list of vehicle makers that issue them does not include Toyota. That is a verified negative and it is the entire claim available. What Toyota Motor Manufacturing Texas asks of its own suppliers sits in documents that are not public. We have not read them. Anyone telling you what is in them is guessing.
And two standards this metro genuinely runs on are ones we do not offer at all: IATF 16949 in the automotive tier, and AS9110 across the aerospace maintenance campus.
Industry in San Antonio
- Toyota Motor Manufacturing Texas $3.6 billion and 2,000 new jobs announced July 2026, adding a second assembly line and roughly 2.5 million square feet by 2030, with 23 suppliers already on site — Bexar County, inside the metro
- What is actually published about the requirements The IATF's own list of vehicle makers issuing customer-specific requirements does not include Toyota. That is a verified negative and it is all anyone can honestly claim — the supplier manuals themselves are not public
- The aerospace maintenance campus Airframe and engine MRO, which runs on AS9110 rather than AS9100. AS9110 is outside what we offer; the AS9100 suppliers feeding the depot are not
- A named ISO/IEC 17025 anchor institution A major independent research institute here holds testing laboratory accreditation to ISO/IEC 17025 alongside ISO 9001 certification and federal recognition as a testing laboratory
- Medical laboratories The second-highest concentration of any market we serve, unusual for a metro this size and a product of the military and academic medical presence
Two boundaries in one metro, which is unusual enough to say out loud
Most markets have one credential we cannot serve. San Antonio has two, and between them they cover the metro's two most visible manufacturing employers.
IATF 16949 governs the automotive tier. If a vehicle manufacturer's program has flowed that down to you contractually, we are not your firm, and no amount of ISO 9001 work substitutes for it.
AS9110 is the one people get wrong here. The aerospace campus at Port San Antonio is predominantly maintenance, repair and overhaul — airframe and engine work, completions, modifications, avionics and component upgrades — and the standard for maintenance organizations is AS9110, not AS9100. They are different documents for different activities, and a supplier told to pursue “AS9100” when the customer meant AS9110 has bought the wrong project. We offer neither, but knowing which one you have actually been asked for is worth something regardless of who does the work.
We are also not going to quote you an employment figure for that campus. The Port publishes no aerospace headcount, and every number circulating for it comes from somewhere other than the Port.
What we are left with is the rest of the metro, and it is not small: 1,333 manufacturing establishments, 1,234 of them employing fewer than 100 people (US Census County Business Patterns, 2023) — a 93% small-firm share.
A four-year transition is a different problem from a new plant
Suppliers into a brand-new plant and suppliers into an expanding one face different work, and the second is the harder to plan for.
A greenfield site qualifies its supply base against a fixed production date. An expansion running a model transition over four years does not. Existing lines keep running while new capacity comes up beside them, volumes shift between products, and a supplier can find itself simultaneously in serial production on one part and in qualification on another, against different timelines, for the same customer.
The specific pressure that creates is on change control and configuration. Two part numbers, two revision states, two sets of approved processes, and a shop floor that has to keep them apart. That is the mechanism by which a supplier with a perfectly adequate quality system fails an audit during a transition: not because the system was bad, but because it was built for one steady state.
It also puts unusual weight on capacity and continuity planning. A four-year ramp means committing to volume increases against forecasts, and clause 8.1 operational planning stops being a documentation exercise the moment the question is whether you can actually make the parts.
For the twenty-three suppliers already on site and the wider tier around them, the practical advice is unglamorous: settle what your customer will hold you to, in writing, before you commit to a certification path. That conversation costs an email. Discovering the answer a year into the wrong project does not.
The laboratory market, and a genuine local anchor
San Antonio has a laboratory and testing base out of proportion to its size, and one institution that makes the point better than any statistic.
Southwest Research Institute publishes its own accreditations, and the list is unusually complete: testing laboratory accreditation to ISO/IEC 17025, inspection agency accreditation to ISO/IEC 17020, ISO 9001:2015 certification, and recognition by federal OSHA as a Nationally Recognized Testing Laboratory, with recognition through the major accreditation bodies and the international mutual recognition arrangements.
That matters locally for a reason beyond prestige. It means the vocabulary of accreditation is already in this market — scopes, methods, measurement uncertainty, proficiency testing — and companies here are more likely than most to encounter a customer or partner who uses those words precisely.
The metro also carries 197 medical laboratory establishments at nearly twice the national concentration, the second highest of any market we serve, which reflects the military and academic medical presence rather than the manufacturing base.
The distinction that catches people is the same one everywhere: organizations are certified to ISO 9001; laboratories are accredited to ISO/IEC 17025. A certificate covers your organization and its activities; an accreditation covers a defined list of methods, and a result reported outside that list is not covered by it. We set the full argument out on our Houston page, where a state rule makes it unavoidable.
The energy economy this metro is known for happens somewhere else
One geographic point worth making because it changes how a San Antonio company should describe itself, and because almost nothing written about this market gets it right.
San Antonio is strongly associated with the Eagle Ford shale, and it does carry an oilfield machinery concentration — 20 establishments at roughly three times the national rate, third among the markets we serve. But the counties that constitute the Eagle Ford — Karnes, La Salle, Dimmit, McMullen, Live Oak, Frio and Gonzales — are not in this metropolitan area. Of the southern counties, only Atascosa and Wilson are.
So the metro's energy-services economy is substantially headquartered here and performed elsewhere. That is not a criticism of the market; it is a description of what kind of market it is, and it matters when you are scoping a management system. A certificate covering “the site” and a business whose work happens across counties two hours south are not automatically the same scope, and multi-site or field-service scoping is a decision to make deliberately.
The metropolitan area is Atascosa, Bandera, Bexar, Comal, Guadalupe, Kendall, Medina and Wilson. New Braunfels spans Comal and Guadalupe and is inside it. San Marcos is not — it belongs to Austin, which is a separate metropolitan area despite how often the two are discussed as one corridor.
Texas has no OSHA state plan, so federal standards apply to private-sector workers here. The Texas divergence that genuinely changes incident procedures — workers' compensation being elective for most private employers — is set out on our Houston page.
How we work with companies here
We are based in the Kansas City metro and run San Antonio engagements remotely, with on-site work at the points where being in the building changes the outcome — the gap analysis walkthrough, the first internal audit cycle, and the certification audits themselves.
For a supplier inside a multi-year transition, the on-site portion concentrates on change control and configuration, because running two revision states through one shop is where otherwise sound systems come apart. Reading the procedure tells you what was intended; following a part number through the paperwork tells you what happens.
The consultant who scopes the engagement does the work. No handoff to a junior implementer after the sale.
What an engagement covers
- ISO 9001 system build A quality management system sized for a company that is probably smaller than the template assumes — 93% of manufacturers here employ fewer than 100 people. See ISO 9001.
- Change control and configuration for a model transition Two part numbers, two revision states, two sets of approved processes, one shop floor. The specific mechanism by which an adequate system fails an audit mid-transition.
- Capacity and operational planning Clause 8.1 stops being a documentation exercise the moment the question is whether you can actually make the parts across a four-year ramp.
- ISO/IEC 17025 for laboratories Accreditation rather than certification — scope definition, method validation and measurement uncertainty, in a metro where the vocabulary is already in use. See ISO/IEC 17025.
- Multi-site and field-service scoping For a business headquartered here and operating across counties outside the metro, what the certificate covers is a decision rather than a default.
- Gap analysis and roadmap Two to four weeks, fixed scope and price, with a clear go or no-go before real money is committed.
- Internal audit and management review Auditor-grade internal audits and a facilitated management review that produces recorded decisions rather than minutes.
Questions we get from companies in this market
Does Toyota require ISO 9001 from its San Antonio suppliers?
We do not know, and we will not pretend to. Toyota does not publish its supplier quality requirements, so nobody writing publicly about this has read them. What is verifiable is a negative: the International Automotive Task Force publishes the list of vehicle makers that issue customer-specific requirements under IATF 16949 — twelve groups including BMW, Ford, General Motors, Mercedes-Benz, Stellantis, Volkswagen and Volvo — and Toyota is not among them. That is all anyone can honestly claim. It does not mean Toyota accepts ISO 9001, and it does not mean IATF 16949 is not required. Ask your buyer and get the answer in writing.
Is it AS9100 or AS9110 for the maintenance campus?
Usually AS9110, and the distinction matters because it is the one most often got wrong here. AS9100 covers design and manufacture; AS9110 covers maintenance organizations. The aerospace campus at Port San Antonio is predominantly maintenance, repair and overhaul — airframe and engine work, completions, modifications, avionics and component upgrades — so AS9110 is generally the relevant standard. We support AS9100 but not AS9110. Either way, a supplier who has been told to pursue AS9100 when the customer meant AS9110 has bought the wrong project, and knowing which is worth something regardless of who does the work.
So what can you actually do in this metro?
The two credentials we cannot serve cover the two most visible employers, not the market. San Antonio has 1,333 manufacturing establishments and 1,234 of them employ fewer than 100 people — a 93% small-firm share. Most of those companies have no automotive program flowdown and no aerospace maintenance approval, and ISO 9001 is what their customers actually ask for. On top of that there is a genuine laboratory market here, where ISO/IEC 17025 accreditation applies rather than certification.
How is supplying an expansion different from supplying a new plant?
It is harder to plan for. A greenfield site qualifies suppliers against a fixed production date. An expansion running a model transition over four years keeps existing lines going while new capacity comes up beside them, so a supplier can be in serial production on one part and in qualification on another, for the same customer, on different timelines. That puts the pressure on change control and configuration — two part numbers, two revision states, one shop floor — which is how a perfectly adequate quality system fails an audit mid-transition. It was built for one steady state.
Is the Eagle Ford part of the San Antonio metro?
No, and this is worth knowing because it changes how a company here should scope a certificate. The counties that constitute the Eagle Ford — Karnes, La Salle, Dimmit, McMullen, Live Oak, Frio and Gonzales — are outside this metropolitan area. Of the southern counties only Atascosa and Wilson are inside it. San Antonio's energy-services economy is substantially headquartered here and performed elsewhere. If your work happens across counties two hours south, a certificate scoped to the site and a certificate scoped to the business are not the same thing, and that is a decision to make deliberately.
What will certification cost?
Audit days are set from the number of people within your certification scope against a published table, then adjusted for factors including system maturity and single-site operation. In this metro the factor that most often moves the number is not headcount but whether field or multi-site activity is inside the scope, which is why we settle that first. Our certification cost breakdown reproduces the table.
