## Key Takeaways

- Website claims of “ITAR compliant” are insufficient. Buyers verify DDTC registration, AS9100D scope in OASIS, technology control plans and NADCAP approvals, then confirm capability with an AS9102 first-article inspection and pilot build.
- ITAR registration is an annual administrative requirement that must be cross-checked against the exact legal entity and current validity period.
- AS9100D certification scope explicitly covers the sourced processes and sites. OASIS database verification is required because supplier-supplied certificates are not authoritative.
- Special processes such as anodizing, plating, welding and passivation require separate NADCAP accreditation by process and facility. AS9100D does not substitute for these approvals.
- Precision Advanced Manufacturing provides ITAR-registered aerospace machining and fabrication services in the US that integrate multi-axis CNC machining, precision fabrication and finishing under one quality system.

## Step 1: Confirm DDTC Registration and Compliance Posture

Under [22 CFR 120.13](https://ecfr.gov/current/title-22/chapter-I/subchapter-M/part-120/subpart-B/section-120.13), any person that manufactures defense articles in the United States must register with the Directorate of Defense Trade Controls. A single manufacturing event triggers this obligation. A manufacturer that does not export still registers.

[22 CFR 122.1(c)](https://ecfr.gov/current/title-22/part-122) explains that registration provides the U.S. Government with information on who engages in specific manufacturing and exporting activities. Registration does not confer export rights or privileges. Registration is the starting point. Compliance requires the controls described in the steps below.

To verify, request current registration evidence from the supplier. Registration is entity-level, covering controlled subsidiaries and affiliates per [22 CFR 122.2(a)](https://ecfr.gov/current/title-22/section-122.2) rather than individual facilities, so confirm the exact legal entity named. Then cross-check the registration number and validity period against the contracting entity and work scope. The [DDTC registration page](https://pmddtc.state.gov/registration) describes the process and confirms that registration does not grant export rights.

Registration renews annually under [22 CFR 122.2(d)–(e)](https://ecfr.gov/current/title-22/section-122.2), with renewal requests due at least 30 days before expiration. Buyers confirm that registration is current and that evidence reflects the present period. A supplier that fails to renew and later re-registers pays fees for any intervening period of manufacturing activity per 22 CFR 122.2(f). That gap signals a lapse in compliance posture.

Items on the U.S. Munitions List fall under DDTC jurisdiction. They sit outside the Export Administration Regulations administered by the Bureau of Industry and Security. [15 CFR Part 734](http://ecfr.gov/current/title-15/part-734) confirms that ITAR-controlled defense articles and technical data remain outside EAR scope. Buyers verify State Department authorization for USML items and avoid relying on EAR classifications.

## Step 2: Reconcile the AS9100D Certificate Against Its Scope in OASIS

AS9100D certification covers a quality management system. The certified scope includes the specific processes being sourced, such as machining, fabrication, assembly and inspection, at the specific certified site. A certificate that covers one process or one location does not extend automatically to others.

To verify, search the supplier in the [IAQG OASIS database](https://governancedocs.com/oasis-database) at oasis.sae.org. Confirm certificate status, standard, scope wording, sites and expiry date. Record the check date in the supplier file. A certificate PDF supplied by the vendor alone lacks authority in aerospace supply chains, as [AS9100 certification and OASIS scope guidance](https://complytrain.net/standards/as9100) explains. Only certification bodies accredited under the IAQG Industry Controlled Other Party scheme issue certificates that appear in OASIS.

Common issues include certificates showing “expired” during recertification, scope that no longer matches a newly added process or product line and missing sites in multi-site organizations. Buyers write OASIS checks into the supplier control procedure, specifying who checks, when and what evidence is retained, to create auditable evidence for AS9100D Clause 8.4.1.

For [precision CNC machining of aerospace components](https://precisionam.com/articles/precision-cnc-machining-aerospace-components/?utm_term=itar-compliant-aerospace-machining-services&utm_campaign=ai_growth_agent), confirm that the OASIS scope statement explicitly covers machining and any fabrication or inspection processes on the purchase order. A scope covering assembly does not cover machining.

![A machined metal part fixtured inside a CNC machining center.](https://cdn.aigrowthmarketer.co/1785163886671-8f5217244f88.webp)**Mission-critical components demand dependable manufacturing processes. Multi-axis CNC machining supports dimensional accuracy and repeatability, backed by material traceability throughout production.**

## Step 3: Review the Technology Control Plan and U.S.-Person Access Controls

Under [22 CFR 120.62](https://www.ecfr.gov/current/title-22/chapter-I/subchapter-M/part-120/subpart-C/section-120.62), a U.S. person includes lawful permanent residents, protected individuals, entities incorporated to do business in the United States and government entities. It excludes any foreign person as defined in Section 120.63. A technology control plan prevents unauthorized access by non-U.S. persons to controlled information and limits any authorized foreign-person access to what a U.S. Government authorization permits, per [32 CFR Part 117](https://ecfr.gov/current/title-32/part-117).

Request the supplier current TCP and confirm that it covers the relevant facility, systems, data, visitors, employees, subcontractors and manufacturing activities. Typical TCP frameworks document controls such as unique badging, escort requirements and segregated work areas. They also cover security indoctrination and encrypted handling of CAD and technical data.

Request a U.S.-person attestation and confirm alignment with the TCP. Verify that the empowered official designated in the supplier DDTC registration is identified and current. A TCP that does not reflect new facilities, new subcontractors or new manufacturing activities represents a compliance gap even when registration remains current.

For programs involving [multi-axis machining for aerospace flight-critical parts](https://precisionam.com/articles/multi-axis-machining-aerospace/?utm_term=itar-compliant-aerospace-machining-services&utm_campaign=ai_growth_agent), confirm that access controls extend to CNC programming systems, CAD/CAM environments and any digital data transfer mechanisms used to receive drawings or transmit inspection results.

![A five-axis CNC head machining a round metal workpiece.](https://cdn.aigrowthmarketer.co/1785163943949-293d9b0cce58.webp)**Five-axis machining supports complex geometries through flexible setups, helping achieve dimensional accuracy and repeatability for aerospace and defense applications.**

## Step 4: Verify Special-Process Approvals Separately

AS9100D certification does not demonstrate approval for welding, plating, anodizing, passivation or other special processes. NADCAP accreditation, administered by the Performance Review Institute, is process-specific and scope-specific. The two address different qualification questions, as [AS9102 first article inspection guidance](https://thestandardsnavigator.com/tag/first-article-inspection-as9102) confirms.

NADCAP chemical processing, category AC7108, covers anodizing, plating, etching and passivation. Welding sits under a separate NADCAP category, AC7146, per [NADCAP special-process scope guidance](https://teeptrak.com/en/aerospace-as9100-mes-implementation-2027). Heat treating accreditation for aluminum alloys does not cover titanium heat treating. Buyers need the specific process, commodity and facility named in the approval.

To verify, identify the exact process and specification on the drawing or purchase order. Then confirm that the supplier NADCAP approval covers that process, the relevant commodity and the performing facility through the PRI supplier database at pri-network.org. Record the verification in the supplier file alongside the OASIS check. Document checks alone still leave one question open: can the supplier execute the work as specified?

Precision Advanced Manufacturing integrates secondary finishing services such as anodizing, passivation and plating as part of its aerospace-aligned finishing offerings. This structure reduces the number of access points across multiple vendors and the traceability gaps that arise when special processes are subcontracted to separate shops.

![Machined metal flanges arranged after finishing and deburring.](https://cdn.aigrowthmarketer.co/1785164177118-60d8e0c39169.webp)**Finishing and deburring support component performance through clean edges, controlled surface finishes, and coatings applied to specification.**

## Step 5: Validate the Supplier With a First-Article and Pilot Build

Document verification establishes a supplier qualifications on paper. A first-article inspection and pilot build prove that the supplier executes to specification in practice. Run an AS9102 FAI with Forms 1, 2 and 3, covering full characteristic accountability, and a pilot build before releasing production.

Under [AS9102 guidance](https://thestandardsnavigator.com/tag/first-article-inspection-as9102), a new or updated FAI is required when a new part number enters production, when a drawing or specification is revised, when a process, facility or tooling change could affect form, fit or function and when production has been inactive for more than two years. A supplier transition mid-program typically triggers a new FAI requirement.

Form 1 covers design documentation and part number accountability. Form 2 covers product accountability, including raw material and special processes. Form 3 covers measurement of every drawing characteristic with measurement device traceability. Accepting a partial FAI as a complete FAI is a common qualification error that surfaces during prime audits.

Precision Advanced Manufacturing supports pilot builds and validation runs to minimize risk during supplier transitions, with complete documentation, material traceability and engineering support. For [mission-critical aerospace machining programs](https://precisionam.com/articles/mission-critical-aerospace-machining/?utm_term=itar-compliant-aerospace-machining-services&utm_campaign=ai_growth_agent), this validation step serves as the final gate before committing full-rate production to a new supplier.

![A CMM touch probe measuring a machined aluminum bracket.](https://cdn.aigrowthmarketer.co/1785164194032-a09872ce26c4.webp)**CMM inspection and controlled quality workflows verify critical dimensions, supporting first-article and in-process inspection with traceable measurement data.**

## Why Integrated Capability Matters for Sustained Production

The five steps above apply to any supplier, but the type of shop matters. Rapid-prototyping-first shops can be a legitimate fit for early development work. They are often ITAR registered and AS9100D certified, and their speed at prototype quantities is a documented strength. Buyers validate production scalability, in-house process depth and special-process coverage before committing full-rate work to a supplier structured for fast prototypes and smaller-to-medium programs.

The trade-off is structural. A shop structured for prototype throughput may route special processes such as welding, anodizing, passivation and plating to subcontractors. Each handoff introduces a foreign-person access point, a traceability gap and a coordination dependency that grows more consequential as production volume increases. Buyers sourcing for [precision machining of satellite and spacecraft components](https://precisionam.com/articles/precision-machining-satellite-spacecraft-components/?utm_term=itar-compliant-aerospace-machining-services&utm_campaign=ai_growth_agent) or sustained defense production verify that the supplier in-house capability matches the production scope and not only the prototype scope.

Precision Advanced Manufacturing offers integrated capabilities that address the full verification checklist under one auditable quality system. Multi-axis CNC machining, precision sheet metal fabrication, specialty welding with thermal distortion control and finishing, including anodizing, passivation and plating, are performed in-house. Two specialized locations in Anaheim, California, and Texas support national programs. Production scales from prototype to full-rate manufacturing without a supplier change, which preserves the traceability chain and the validated quality system across the program lifecycle.

The five-step verification procedure described in this article applies to any supplier. When applied to Precision Advanced Manufacturing, the documented result is a supplier with current DDTC registration, AS9100D and ISO 9001:2015 certifications verifiable in OASIS, in-house TCP-covered facilities, integrated special-process capabilities and a pilot-build support model for supplier transitions.

## Frequently Asked Questions

### Is ITAR Registration the Same as ITAR Compliance?

ITAR registration, governed by 22 CFR Part 122, is a mandatory administrative step that provides the U.S. Government with information on who engages in manufacturing or exporting defense articles. It does not confer export rights or privileges and does not demonstrate that a supplier has implemented the access controls, technology control plan, U.S.-person restrictions, recordkeeping systems or export authorization procedures that constitute operational compliance. A supplier can be registered and still lack the internal controls required to handle ITAR-controlled technical data, drawings or hardware lawfully. Buyers treat registration as the starting point of verification.

### How Do I Verify a Supplier AS9100D Scope Covers Machining and Fabrication?

The OASIS check in Step 2 covers the mechanics. The most common discrepancies involve legal entity name, scope wording, site addresses or expiry dates. Buyers resolve those issues with the certification body so the record, certificate and purchasing documents align before approval.

### What Documents Should Be Requested Before Approving an ITAR-Registered Machine Shop?

A defensible supplier qualification file should include:

- Current DDTC registration evidence showing the legal entity name, registration number and validity period
- The AS9100D certificate reconciled against the OASIS record
- The current technology control plan covering the relevant facility, systems, data and personnel
- A U.S.-person attestation aligned with the TCP
- NADCAP accreditation certificates for any special processes on the drawing or purchase order, verified as described in Step 4
- A completed AS9102 first article inspection package, Forms 1, 2 and 3, for the specific part number being sourced

### When Does a Supplier Transition Require a New First Article Inspection?

AS9102 treats a supplier transition as a trigger for a new FAI because the manufacturing process, facility and tooling change. The new supplier completes a full FAI with all three forms and full characteristic accountability before production release. Step 5 in this article outlines the broader FAI trigger list and the role of the pilot build.

### How Often Should a Supplier Registration and Certifications Be Re-Verified?

DDTC registration renews annually under 22 CFR 122.2(d), so buyers confirm currency at least annually and before awarding new work scope. AS9100D certificates follow a three-year certification cycle with annual surveillance audits. Buyers check OASIS at each re-evaluation and set up watchlist alerts so that status changes, such as suspension, withdrawal or scope reduction, trigger immediate review. NADCAP accreditation cycles run 12 to 24 months depending on the process category and the supplier audit history. A supplier compliance posture can change between periodic reviews, so buyers sourcing for sustained production programs build re-verification checkpoints into the supplier management procedure.

## Conclusion: Build the Shortlist on Verifiable Evidence

An “ITAR compliant” banner on a supplier website tells the buyer nothing verifiable. A defensible shortlist comes from verifying DDTC registration against the current legal entity, reconciling the AS9100D certificate against the OASIS scope record, reviewing the technology control plan and U.S.-person access controls, confirming NADCAP approvals by process and commodity and validating the supplier through an AS9102 first article inspection and pilot build before committing production.

Precision Advanced Manufacturing meets that standard. The company is ITAR registered, AS9100D and ISO 9001:2015 certified, with machining, fabrication, welding and finishing under one auditable quality system.

The five steps in this article function as a repeatable checklist. Applied consistently, they highlight the supplier that clears all five steps with documented evidence and reduces program risk.
