## Key Takeaways

- ITAR and AS9100 address different risks. ITAR controls access to defense articles and technical data. AS9100 governs aerospace quality management systems.
- Each credential stands on its own. An AS9100-certified supplier can still violate ITAR. An ITAR-registered supplier can still produce nonconforming hardware.
- ITAR registration is a legal obligation under federal law. AS9100 certification is a contractual requirement driven by customer and prime contractor standards.
- Verification uses different records. ITAR relies on DDTC registration and export authorizations. AS9100 relies on an accredited certification body certificate in the IAQG OASIS database.
- Precision Advanced Manufacturing holds both ITAR registration and AS9100D certification, supporting defense and aerospace programs with aligned compliance and quality systems.

## How ITAR and AS9100 Differ in Scope and Purpose

ITAR, the International Traffic in Arms Regulations, is administered by the [U.S. Department of State Directorate of Defense Trade Controls](https://deccs.pmddtc.state.gov/ddtc_public) under the Arms Export Control Act. [AS9100 is the aerospace quality management system standard maintained by the International Aerospace Quality Group and published on its behalf by regional bodies such as SAE International in the Americas](https://iso9001expert.com/blog/iso-9001-as9100-rev-d-aerospace-adds-quality-management), with certification administered through the IAQG certification scheme.

ITAR governs who may access, handle, transfer or export defense articles and controlled technical data. AS9100 governs whether an organization has documented processes, controls and audit history to build aerospace products consistently and to specification. ITAR functions as an access and transfer control regime. AS9100 functions as a quality management framework. They address different risks and require separate verification.

The paired attributes break down as follows.

- **Purpose:** ITAR restricts access to and transfer of defense articles and technical data. AS9100 establishes quality management system requirements for aviation, space and defense manufacturing.
- **Governing body:** ITAR is administered by DDTC under the Arms Export Control Act. AS9100 is maintained by the IAQG and published by SAE International in the Americas.
- **Mandatory vs. voluntary:** [Under 22 CFR 122.1(a), ITAR registration is a legal obligation for persons who engage in the United States in the business of manufacturing, exporting or temporarily importing defense articles, or furnishing defense services, subject to the exemptions listed in 22 CFR 122.1(b)](https://www.ecfr.gov/current/title-22/chapter-I/subchapter-M/part-122). [AS9100 certification is contractually and customer-required, not a statute](https://compassprecision.com/what-is-as9100d-certification-and-why-it-matters-for-aerospace-component-suppliers).
- **What it controls:** ITAR controls who receives controlled items and data. AS9100 controls how products are designed, built, inspected and traced.
- **Credential type:** [ITAR registration produces a DDTC registration submitted via Form DS-2032 in DECCS and resulting in a registration code assigned by DDTC, but it does not confer export rights or privileges](https://www.pmddtc.state.gov/sys_attachment.do?sys_id=740e92d9972d0f9067b1791ad053af17). [AS9100 produces a certificate issued by an accredited certification body after an audit](https://compassprecision.com/what-is-as9100d-certification-and-why-it-matters-for-aerospace-component-suppliers).
- **Consequence of failure:** ITAR violations carry civil and criminal exposure under federal law. AS9100 nonconformances can result in certificate suspension, loss of customer approval and program disqualification.

## Registration Versus Certification in Practice

ITAR registration functions as a legal enrollment with DDTC submitted through the [Defense Export Control and Compliance System Portal](https://deccs.pmddtc.state.gov/ddtc_public). Registration establishes that an organization is subject to ITAR obligations and is eligible to apply for export authorizations. [Registration and licensing are separate transactions, and registration does not authorize any specific export](https://deccs.pmddtc.state.gov/ddtc_public).

AS9100 certification is issued by an accredited certification body after a structured audit confirms that the organization’s quality management system meets the standard requirements. [Certification bodies must be accredited under the IAQG AS9104 scheme](https://iso9001expert.com/blog/iso-9001-as9100-rev-d-aerospace-adds-quality-management), which [imposes auditor qualification requirements beyond general ISO 9001 accreditation rules](https://iso9001expert.com/blog/iso-9001-as9100-rev-d-aerospace-adds-quality-management).

The key distinction is clear. DDTC registration is not a compliance certificate, and [an AS9100 certificate is not export authorization](https://bescast.com/what-is-as9100-certification). Each document proves a specific point and nothing beyond that.

## ITAR Registered Versus AS9100 Certified Suppliers

Suppliers can hold one credential without the other, and each gap creates program risk.

An [AS9100-certified shop can still mishandle controlled technical data](https://iso9001expert.com/blog/iso-9001-as9100-rev-d-aerospace-adds-quality-management) and commit a federal export violation if it is not ITAR registered or does not follow ITAR requirements. [AS9100 audits primarily evaluate an organization’s quality management system against the standard and do not certify compliance with export control obligations such as UK strategic export controls or ITAR or EAR, though auditors may check whether the organization has identified applicable export control requirements](https://aligntra.com/resources/checklists/as9100d-audit). A quality certificate does not establish that a supplier has screened foreign nationals, restricted access to controlled drawings or obtained required export authorizations.

An ITAR-registered shop can still have weak process control and produce nonconforming or scrapped flight hardware. [ITAR registration does not substitute for AS9100, DFARS cybersecurity compliance or export authorization](https://bescast.com/what-is-as9100-certification). Registration confirms legal enrollment, not manufacturing discipline.

Verification of one credential does not verify the other. Each requires its own document and its own check.

[ITAR Compliant CNC Aerospace Machining: 8-Step Vetting Guide](https://precisionam.com/articles/itar-compliant-cnc-aerospace-machining/?utm_source=ai-growht-agent&utm_term=itar-vs-as9100-aerospace-differences) covers the supplier-vetting process in depth for programs where both credentials are in scope.

## Documents That Demonstrate Each Credential

ITAR evidence includes confirmation of DDTC registration and, where controlled technical data or hardware is involved, the applicable export authorization such as a license or documented exemption basis. Programs also look for confirmation of restricted-party screening and data-handling controls. [DDTC publishes guidance on whether registration is required](https://deccs.pmddtc.state.gov/ddtc_public) as a distinct step from applying for an export license or agreement. Registration status and license history appear as separate records within the DECCS portal.

AS9100 evidence centers on the certificate from an accredited certification body. [AS9100 certification data is uploaded by the certification body to OASIS](https://iso9001expert.com/blog/iso-9001-as9100-rev-d-aerospace-adds-quality-management), the Online Aerospace Supplier Information System maintained by IAQG, and [aerospace primes use OASIS to verify a supplier’s certification status, scope and audit history](https://iso9001expert.com/blog/iso-9001-as9100-rev-d-aerospace-adds-quality-management). Review of a certificate should confirm that the scope statement covers the actual work, that the revision is AS9100D and that the expiry date is current.

Each artifact proves a narrow point. An AS9100 certificate proves that the quality management system met the standard requirements at the time of the audit. It does not prove ITAR registration. A DDTC registration record proves enrollment under the Arms Export Control Act. It does not prove process control or manufacturing quality.

[AS9100 ITAR CNC Machining: Evaluating Registered Suppliers](https://precisionam.com/articles/as9100-itar-cnc-machining/?utm_source=ai-growht-agent&utm_term=itar-vs-as9100-aerospace-differences) provides additional guidance on evaluating both credentials in a supplier qualification context.

## Two Common Failure Scenarios

The first failure scenario involves an AS9100-certified supplier that mishandles controlled technical data. If foreign nationals access ITAR-controlled drawings without authorization, or if controlled hardware ships without required export authorization, the result is a federal export violation. Civil and criminal exposure attaches under the Arms Export Control Act regardless of the supplier’s quality certification status.

The second failure scenario involves an ITAR-registered supplier with weak process control that produces nonconforming flight hardware. Without documented processes, configuration management, counterfeit-part prevention and traceability requirements that [AS9100D requires](https://compassprecision.com/what-is-as9100d-certification-and-why-it-matters-for-aerospace-component-suppliers), parts may fail to meet specification, require rework or scrap and introduce program delay. ITAR registration provides no assurance of manufacturing quality.

Both scenarios create significant program risk. Both are preventable when teams verify each credential independently with the correct documentation.

## How Defense Contracts Apply ITAR and AS9100

The applicable quality standard depends on the organization’s role in the supply chain. [AS9100 applies to manufacturers of aviation, space and defense products, AS9110 applies to maintenance, repair and overhaul organizations, and AS9120 applies to stockists and distributors](https://governancedocs.com/as9110-vs-as9120) that buy and resell aerospace parts without manufacturing or materially altering them. A manufacturer of flight hardware typically needs AS9100. An MRO organization fits AS9110. A distributor fits AS9120.

ITAR obligations attach based on whether defense articles or controlled technical data are involved, independent of the quality standard. A distributor certified to AS9120 that handles ITAR-controlled parts still requires DDTC registration.

[No single federal statute makes AS9100 certification a blanket legal precondition for every defense contract](https://bescast.com/what-is-as9100-certification). AS9100 becomes mandatory when the applicable prime contract, subcontract, purchase order or customer specification expressly requires it. ITAR functions as law. AS9100 functions as a contractual and customer requirement that operates as a practical condition of entry into the aerospace supply chain.

[AS9100D is the current revision](https://epsilon3.io/behind-the-console/iso-9001-vs-as9100-what-ops-teams-need-to-know), [released in September 2016](https://resources.utec.co/mh-aerospace-gse/as9100d-to-ia9100-aerospace-tooling-suppliers) and [built on the ISO 9001:2015 quality management basis](https://resources.utec.co/mh-aerospace-gse/as9100d-to-ia9100-aerospace-tooling-suppliers). [The IAQG is developing a successor standard, IA9100, aligned with ISO 9001:2026](https://resources.utec.co/mh-aerospace-gse/as9100d-to-ia9100-aerospace-tooling-suppliers), with a transition window expected to give certified organizations time to recertify. AS9100D certificates remain valid through that transition. IA9100 represents a revision under a new naming convention, not a separate standard.

## Why Programs Want Both and Where Precision Advanced Manufacturing Fits

Defense and space programs require both credentials because each addresses a different risk. ITAR registration protects against unauthorized access to and transfer of controlled defense articles and technical data. AS9100 certification protects against process failures, nonconforming hardware and traceability gaps that can ground a program.

Precision Advanced Manufacturing holds both credentials. The company is ITAR registered and operates under AS9100D and ISO 9001:2015 certified quality management systems, with locations in Anaheim, California, and Texas. Precision Advanced Manufacturing serves commercial aerospace, military and defense, space and satellites, advanced industrials and UAV programs, delivering high-precision machined and fabricated components with full traceability and documentation aligned to aerospace quality standards.

Procurement, program management and supplier quality teams gain a clear example of a machining and fabrication partner that holds both credentials, with certified processes, documented quality systems and ITAR-compliant operations built into every production step.

## Frequently Asked Questions

### Is AS9100 Required by Law

AS9100 certification is not a statute. It becomes mandatory when a prime contract, subcontract, purchase order or customer specification expressly requires it. Major aerospace OEMs and defense prime contractors write AS9100 into supplier quality requirements as a standard contract clause, which makes it a practical condition of doing business even though it remains a contractual requirement. ITAR functions as federal law administered under the Arms Export Control Act. Failure to register or comply with ITAR carries civil and criminal exposure regardless of quality certification status.

### Can a Company Be AS9100 Certified but Not ITAR Compliant

AS9100 certification and ITAR registration operate as independent credentials. An AS9100-certified organization has demonstrated that its quality management system meets the standard requirements. That audit does not assess whether the organization is registered with DDTC, whether it has obtained required export authorizations or whether it has implemented access controls and restricted-party screening that ITAR requires. A supplier can hold a current AS9100D certificate and still fall out of compliance with ITAR if it handles controlled defense articles or technical data without required registration and authorizations.

### What Document Proves ITAR Compliance

ITAR compliance does not rely on a single certificate. Relevant evidence includes confirmation of DDTC registration through the Defense Export Control and Compliance System portal, the applicable export authorization such as a license or documented exemption basis for any controlled hardware or technical data and confirmation of restricted-party screening and data-handling controls. Registration and licensing appear as separate records. A supplier claim of ITAR compliance should be checked against each of these elements, not accepted on the basis of a combined statement or a quality certificate.

### Do Both Credentials Apply to a Defense Contract

Most defense manufacturing programs require both. A manufacturer of flight hardware or defense components typically needs AS9100 certification as a contractual condition and ITAR registration when the program involves controlled defense articles or technical data. The two obligations stack, and each remains distinct. The applicable quality standard, such as AS9100 for manufacturers, AS9110 for MRO organizations or AS9120 for distributors, depends on the organization’s role in the supply chain. ITAR obligations attach based on whether controlled items or data are involved, independent of the quality standard.

### What Is AS9100 Being Replaced With

AS9100D is the current revision, published in September 2016 and built on the ISO 9001:2015 quality management framework. The IAQG is developing a successor standard called IA9100, aligned with ISO 9001:2026, under the IAQG International Aerospace naming convention. A transition window is expected to allow certified organizations time to recertify. AS9100D certificates remain valid through that transition period. IA9100 represents a revision of the same standard under a new name, not a separate framework. Organizations holding current AS9100D certificates can monitor IAQG guidance on transition timelines and plan accordingly.

### How Hard Is It to Get AS9100 Certified

AS9100 certification requires an organization to build and operate a documented quality management system that meets all requirements of the standard, conduct internal audits, complete a management review and pass a two-stage audit by an accredited certification body. Organizations that already operate a mature ISO 9001 system have completed a substantial portion of the work, since [AS9100D contains the full text of ISO 9001:2015 and layers aerospace-specific requirements on top of it](https://iso9001expert.com/blog/iso-9001-as9100-rev-d-aerospace-adds-quality-management). Organizations building configuration management, counterfeit-part prevention and product safety processes from scratch face a longer path. [Certification is valid for three years, with annual surveillance audits required to maintain it](https://bescast.com/what-is-as9100-certification).

## Conclusion: Treat ITAR and AS9100 as Separate Checks

ITAR and AS9100 address different questions. ITAR controls who may access and receive controlled defense articles and technical data. AS9100 controls how consistently an aerospace product is built and quality-managed. Each credential stands on its own, and accepting a combined claim without separate verification introduces program risk on two dimensions.

Teams can verify ITAR registration and applicable export authorizations through DDTC records. Teams can verify AS9100D certification through the IAQG OASIS database, confirming scope, revision and expiry. Each check functions as a distinct step in supplier qualification.

Precision Advanced Manufacturing’s aerospace specialists support program needs, part specifications and compliance requirements and provide tailored quotes for machining and fabrication work that requires both ITAR registration and AS9100D certified quality systems.
