Search for AS9100 certification, and you will find dozens of registrars, each promising an accredited result. Some issue AS9100 only. Others combine AS9100 with ISO 13485 or ISO 27001 under one engagement.
For a supplier that builds aerospace parts, handles sensitive program data, or moves into medical component work, that choice matters. It decides how many vendors you manage, how long certification takes, and how much you spend across every standard you need.
This guide compares single-standard and multi-standard AS9100 certification body options so you can match the model to your actual scope of work.
Weighing the real AS9100 certification benefits against your future certification needs, not just today's audit, prevents a costly second search six months from now.
Quick Comparison: Single-Standard vs. Multi-Standard AS9100 Certifiers
A multi-standard certifier consolidates AS9100, ISO 13485, and ISO 27001 into one process, while a single-standard certifier focuses only on aerospace quality management.
What a Multi-Standard Certifier Like KSQA Does Best
K&S Quality Assessments LLC (KSQA) issues AS9100, ISO 9001, ISO 13485, and ISO 27001 certificates under one fixed price, virtual first process, so a diversified supplier does not have to restart the vetting process with a second registrar.
KSQA is accredited by the International Accreditation Service under MSCB-207 for management systems and ASA-101 for aerospace standards.
KSQA also holds membership in both the IAF Multilateral Recognition Arrangement and the IAQG.
“The IAQG maintains the official 9100 series requirements referenced at iaqg.org/standards.”
Suppliers who need AS9100 alongside ISO 13485 or ISO 27001 can complete every audit with one registrar instead of coordinating separate contracts and separate auditors.
One Certifier for AS9100, ISO 13485, and ISO 27001
A supplier that builds aerospace components and also handles government contract data often needs both AS9100 and ISO 27001.
A supplier that produces machined parts for both aviation and medical device clients often needs both AS9100 and ISO 13485. KSQA issues all four standards, so the AS9100 certification benefits extend into future certification needs without a second vendor search.
According to the DoD Office of Small Business Programs, “defense contractors handling controlled information must meet cybersecurity obligations that closely mirror ISO 27001 controls.”
A supplier already certified to AS9100 through KSQA can add ISO 27001 through the same registrar instead of starting a new vetting process with a different certification body.
Fixed-Price, 2-3 Day Certification Across Every Standard
KSQA has performed aerospace and quality management audits for more than 20 years and completed hundreds of successful certifications. Certificates are issued within 2 to 3 days of a successful audit, compared with the 30 to 45-day timeline common among traditional registrars.
This turnaround applies whether a supplier needs one standard or three. The certification decision and the surveillance schedule follow the same fixed-price structure across AS9100, ISO 9001, ISO 13485, and ISO 27001.
Why Bundled Certification Solves a Problem Competitors Don't Address
Most certification bodies write about AS9100 and ISO 13485 as separate decisions.
One large aerospace registrar markets an integrated audit bundle for ISO 9001, ISO 14001, and ISO 45001, yet that bundle never includes AS9100 or ISO 13485, even though the same registrar certifies suppliers to both standards individually.
That gap leaves a diversified aerospace and medical-component supplier coordinating two separate audit relationships when a single registrar could issue both.
Before signing with any certifier, ask directly whether AS9100 and ISO 13485 can be issued under one contract, not just whether both standards appear somewhere in the registrar's catalog.
What Single-Standard AS9100 Certification Bodies Offer
Single-standard AS9100 certifiers focus their auditors and processes on aerospace quality management only. Some are accredited through ANAB or UKAS rather than IAS, and several have decades of aerospace-specific audit experience.
This narrow focus can suit a supplier that manufactures exclusively for aviation, space, or defense customers. It fits well when there are no plans to pursue ISO 13485 or ISO 27001.
However, several well-known aerospace registrars do not offer ISO 13485 or ISO 27001 at all. A supplier that later needs either standard must open a second vendor relationship, submit to a new vetting process, and manage two separate audit calendars going forward.
The Key Differences That Matter for Diversified Suppliers
The real difference between these two certifier types is not audit quality. The difference comes down to how many vendor relationships your business will need to manage over time.
Vendor Count
Yes, a single-standard AS9100 certification body can bring deep, aerospace-only audit experience. But that focus usually means the registrar cannot also issue ISO 13485 or ISO 27001.
A supplier expanding into medical components or handling sensitive data ends up managing two or three separate certification bodies, two renewal calendars, and two sets of surveillance audits instead of one.
Timeline and Budget Predictability
Yes, some single-standard certifiers have operated in the aerospace space longer. But longer tenure in one standard does not guarantee predictable pricing across multiple standards.
“The FDA's Quality Management System Regulation, effective February 2, 2026, now incorporates ISO 13485:2016 directly into 21 CFR Part 820, according to the FDA.”
Medical device suppliers now face a firm regulatory deadline tied to that standard.
A supplier meeting that deadline while also holding AS9100 benefits from one fixed-price registrar handling both standards on a known 2- to 3-day certification timeline, instead of coordinating two separate quotes under time pressure.
Which Certification Body Is Best for You?
A single-standard AS9100 certification body is best for suppliers who manufacture exclusively for aerospace, aviation, or defense customers, have no plans to add ISO 13485 or ISO 27001, and prioritize a registrar with a long, aerospace-only track record.
A multi-standard AS9100 certification body is best for suppliers who already need or expect to need:
ISO 13485 for medical component work
ISO 27001 for handling sensitive program data
ISO 9001 across general operations and who wants the full AS9100 certification benefits without managing more than one registrar relationship.
Frequently Asked Questions (FAQs)
Q1. Can one certification body issue both AS9100 and ISO 13485?
Yes. A multi-standard AS9100 certification body such as KSQA can audit and certify a supplier to AS9100, ISO 13485, and ISO 27001 under one fixed-price engagement, so a business does not need separate contracts with separate registrars for each standard.
Q2. What are the AS9100 certification benefits of choosing a multi-standard certifier?
The main AS9100 certification benefits of a multi-standard certifier are fewer vendor relationships, one renewal calendar instead of several, and a single fixed price covering every standard a diversified supplier needs, rather than separate quotes for each certification.
Q3. How long does AS9100 certification take with a multi-standard certifier?
KSQA issues AS9100 certificates within 2 to 3 days of a successful audit, whether a supplier is certifying to AS9100 alone or adding ISO 13485 or ISO 27001 at the same time.
Q4. Do single-standard AS9100 certifiers cost less than multi-standard certifiers?
Not necessarily. Single-standard certifiers often quote each standard separately. A supplier needing AS9100 and a second standard from two different registrars may pay more in total than working with one fixed-price, multi-standard certifier.
Q5. Is a multi-standard certifier accredited the same way as a single-standard certifier?
Accreditation depends on the certification body, not the number of standards it offers. KSQA is accredited by the International Accreditation Service under MSCB-207 and ASA-101 and holds IAF and IAQG membership, which carries the same international recognition as ANAB or UKAS accreditation.
Final Verdict
Choosing between a single-standard and multi-standard AS9100 certification body is really a question about your next two or three years, not just your next audit. If your operations will stay aerospace-only, a single-standard certifier's deep focus may fit.
If you already touch medical components, sensitive data, or general quality management alongside aerospace work, a multi-standard AS9100 certification benefit removes the need to repeat the vetting process with a second registrar every time your scope grows.
