How to Display ISO 9001 and Other Certifications on Your Manufacturing Website

To display ISO 9001 certification on your website, write "certified to ISO 9001:2015" rather than a bare "ISO certified," then publish the details a buyer can check: the exact scope wording from the certificate, the certified site addresses, the name of the certification body that issued it, the certificate number, and the expiry date. Leave the ISO logo off the page. ISO does not certify companies and does not permit its logo to be used in connection with certification, so if you want a mark, ask your certification body for one and follow its rules.

Why buyers check instead of taking your word for it

Before your shop goes on an approved supplier list, someone compares the scope on your certificate to the work they want to send. If the certificate reads "machining of aluminum and steel components" and the buyer needs welded assemblies, a loose paraphrase like "ISO 9001 certified machining and fabrication" costs you the job. That check comes earlier in the process than most shops expect.

How to show ISO 9001 correctly

Use the right wording

ISO develops standards. It does not certify anyone, and it says you should not describe yourself, your products, or your services as endorsed, approved, or certified by ISO. Certification bodies, often called registrars, do the certifying.

Best: "certified to ISO 9001:2015," the full reference ISO asks for, matching what is printed on your certificate.
Workable: "ISO 9001 certified" in a headline or footer strip, if the edition and certificate details appear lower on the page.
Avoid: "ISO certified," "certified by ISO," and "ISO accredited." An organization is certified by a certification body, and it is the certification body that holds accreditation.

Leave the ISO logo off your site

The ISO logo and short name are ISO trademarks, reserved for ISO, its members, and its technical committees. ISO does not permit anyone to use that logo in connection with certification, and there is no separate ISO 9001 logo to use instead. Do not redraw it either, and make sure any graphic you design in house cannot be mistaken for it.

Marks come from your certification body, not from you

For a visual mark, contact the certification body that issued your certificate and use the file it provides, under your certification agreement. Accreditation body symbols work the same way, one step further up. ANAB, for example, authorizes its accredited conformity assessment bodies to use its symbol, and a certified organization may use that symbol only in the combined form its certification body supplies. Never download an accreditation symbol yourself. Ask your registrar which marks you may display, and use the artwork it sends.

Publish the fields buyers verify

IAF CertSearch is a global database of accredited management system certificates, but it is only as complete as its contributors: IAF supplies data on accreditation bodies, accreditation bodies supply data on their certification bodies, and certification bodies supply the certificate records. A valid certificate is simply absent when the registrar behind it does not contribute. Free public searching also requires an account and is capped at a few lookups a day, so publish the fields yourself:

Standard: ISO 9001:2015
Scope: [exact wording from the certificate]
Certified site(s): [street address, city, state]
Certification body: [registrar name]
Certificate no.: [number]
Valid through: [date]

Show the edition printed on the certificate you hold rather than the one you expect next, put a calendar reminder on the expiry, and update every place the claim appears the day your registrar reissues.

Mark the fields up as structured data

Schema.org defines a Certification type and a hasCertification property that attaches it to your Organization markup. Watch the spelling: the certificate number goes in certificationIdentification, the registrar in issuedBy, and Certification also defines certificationStatus, validIn, auditDate, and expires. Repeat the block once per credential.

AS9100, ISO 13485, and process accreditations

Aerospace buyers look for AS9100, then check OASIS, the International Aerospace Quality Group's Online Aerospace Supplier Information System. Make sure the company name, site addresses, and scope wording in your OASIS record match your website exactly, and advertise the revision on your certificate, such as AS9100D, until your registrar moves you to a newer one. An aerospace machine shop website follows the same pattern: certificate fields as real text, then the badge.

ISO 13485:2016 is the quality management system standard written for organizations in the medical device sector, and it serves regulatory purposes rather than marketing ones. Present it exactly like ISO 9001. The rule shops get wrong: a certificate from a registrar is not clearance, approval, or any other decision by a regulator, so never let a medical device website imply that a quality system certificate means FDA approved a device or a facility.

Nadcap, administered by the Performance Review Institute, accredits critical processes and product-related services rather than a whole company or its quality system, covering process areas such as heat treating, nondestructive testing, and welding, among others. It is the one scheme here where the supplier itself is accredited rather than certified, so keep PRI's wording for Nadcap and ISO's wording for ISO. List each accredited process by name, and note your listing on the Qualified Manufacturers List, which PRI publishes through its eAuditNet platform, also branded PRI EAN. IATF 16949 comes from the International Automotive Task Force rather than ISO and is applied together with ISO 9001. A CAGE code only identifies your facility for US government work, so list it under company information.

How to show ITAR registration (it is not a certification)

There is no ITAR certificate and no ITAR logo, only registration with the State Department's Directorate of Defense Trade Controls. Under 22 CFR 122.1, anyone in the United States in the business of manufacturing, exporting, or temporarily importing defense articles, or furnishing defense services, is required to register, and the rule says a manufacturer who does not export must nevertheless register. The same section states that registration does not confer any export rights or privileges, so never write "ITAR certified" or imply that registering authorizes an export. Write it as "Registered with the U.S. State Department, Directorate of Defense Trade Controls (DDTC)," and keep the date current: registration expires and has to be renewed, with a fee tiered under 22 CFR 122.3 starting at a set $3,000 per year for Tier 1.

What to write if you are not certified or your certificate lapsed

Not certified, but running a system built to the standard: write "our quality management system is built to ISO 9001:2015 requirements; not certified." Use no certification mark, and never shorten it to "ISO 9001 compliant," which a buyer reads as certified.
Audit scheduled: name the month. "ISO 9001:2015 certification audit scheduled for March 2027" is honest. "AS9100 certified (in process)" is not, because the first two words are what a buyer remembers.
Suspended, withdrawn, or expired: take the claim down the same day, including badges, page copy, the footer strip, and any PDF line card on the site.

How to structure a quality page

One quality page that does the verification work beats a row of logos. Open with a short summary of your quality system, then:

One block per certification, with the standard, the edition, and the certificate fields in text, plus only the marks your certification body approved. Keep process accreditations and government registrations in separate sections so nothing reads as a certification it is not.
Inspection equipment and methods: CMM make, model, and measuring envelope; first article inspection reporting; calibration traceability.
A downloadable copy of each certificate, never an image-only scan that no text search or AI assistant can read. Give badge images alt text naming the standard and edition rather than "certification logo."

Everywhere else carries a pointer to that page: a strip such as "ISO 9001:2015 and AS9100D certified | ITAR registered" on the home page, beside your RFQ form, in the footer, and on every capabilities page, as real text rather than only a badge image.

You can edit your content whenever you like, whether the site stays with us or moves elsewhere. Start on the get started page.

Frequently asked questions

Can I put the ISO logo on my website if we are ISO 9001 certified?

No. ISO does not certify organizations and does not permit its logo to be used in connection with certification, and there is no separate ISO 9001 logo. Contact the certification body that issued your certificate, use the mark it provides under its rules, and write "certified to ISO 9001:2015."

What certificate details should a manufacturing website show?

The standard and its edition, the exact scope wording from the certificate, the certified site addresses, the name of the certification body that issued it, the certificate number, and the expiry date. Those are the details a buyer compares before adding you to an approved supplier list.

Is ITAR a certification?

No. It is registration with the State Department's Directorate of Defense Trade Controls. Under 22 CFR 122.1 anyone in the business of manufacturing, exporting, or temporarily importing defense articles, or furnishing defense services, must register, and a manufacturer who does not export must register anyway. Registration confers no export rights or privileges, so write "registered with DDTC," never "ITAR certified."

Where do aerospace buyers check an AS9100 certificate?

In OASIS, the International Aerospace Quality Group's Online Aerospace Supplier Information System, which lists suppliers certified under IAQG rules to the 9100 series and requires a user account to access. Keep the company name, sites, and scope in that record identical to the certificate fields published on your website.
