#U.S. Aerospace CNC Machining Suppliers: Compare Certification, ITAR, and Inspection

#Which aerospace CNC machining provider fits your program?

• Vendra is our managed manufacturing and sourcing service for aerospace and defense teams that need custom parts made in America. Our engineers review each request for quotation (RFQ), match parts with vetted U.S. shops, and coordinate production and inspection. Vendra states that it holds AS9100 certification. If your order requires certified manufacturing, ask us to identify the proposed shop and verify that its certificate covers the work.
• Protolabs offers rapid prototypes and on-demand production through its aerospace CNC service. Verify that the quoted service and production site meet your program’s requirements.
• Xometry offers network-based CNC quotes through its aerospace machining service. Its aerospace credentials, production location, and inspection commitments need current verification before selection.
• Fictiv describes an aerospace machining supplier network. Confirm the assigned shop’s location and credentials before sending controlled files.

For a U.S.-only order that needs coordinated production and inspection records, evaluate Vendra. For rapid prototypes or low-volume production, evaluate Protolabs. Xometry and Fictiv offer network-based sourcing, but confirm the assigned production site before relying on a network-wide claim. Compare each quote against the same requirements for certification, controlled data, inspection, and delivery.

#Why aerospace sourcing is different from general CNC sourcing

An aerospace CNC quote can leave contract requirements unpriced. A general RFQ may specify the alloy, dimensions, and quantity but omit where the part must be made or which records must accompany it. A quote that excludes those requirements may need to be revised or moved to another shop before production can begin.

AS9100D specifies aerospace quality-management requirements in addition to ISO 9001 requirements. Check whether your contract requires it, then verify the certificate holder, site, and scope. For work subject to the International Traffic in Arms Regulations (ITAR), confirm the export classification with your compliance contact before sharing drawings or CAD files. Identify who would receive or access the files, including any foreign persons in the United States, and determine what authorization is required. Where Directorate of Defense Trade Controls (DDTC) registration is required, request evidence of the relevant entity’s current registration. Registration does not by itself authorize a controlled technical-data transfer. Department of Defense (DoD) contracts may also include Defense Federal Acquisition Regulation Supplement (DFARS) cybersecurity clauses for Controlled Unclassified Information (CUI). Check the clauses that apply to your order because ITAR registration does not satisfy separate cybersecurity obligations.

AS9102 sets requirements for documenting a first article inspection (FAI). An AS9100D certificate does not mean an AS9102 report is included with an order. If your contract calls for an AS9102 report, the supplier must document the required inspection results against the applicable design requirements. A customer may reject an incomplete report even if the measured part meets its drawing requirements.

Compare quoted tolerances and capacity against your part and schedule. Confirm whether each proposed site can provide the material traceability and inspection records your order requires.

#Managed supplier networks vs. individual machine shops

A managed manufacturing partner can coordinate shop selection, production, and documentation across an order. Vendra’s aerospace page says its engineers review RFQs and match parts with vetted U.S. manufacturers. Buying from an individual machine shop gives you a direct relationship with the facility making the part. A managed network can also provide that access; Vendra says customers can communicate with the assigned shop. If that shop cannot meet the job’s equipment or capacity requirements, you may need to qualify another supplier.

A marketplace can help you compare supplier quotes for price and availability. Before ordering, identify the proposed shop and verify its certification, location, and arrangements for handling your drawings. The marketplace’s credentials do not establish those details for each shop.

For a part that may require multiple processes or supplier handoffs, ask who will own coordination and documentation. For a repeatable part at an already qualified facility, a direct shop relationship may be simpler.

#Vendra

Best for: Aerospace and defense teams sourcing custom parts in the U.S. that want one partner to match each part with a suitable manufacturer and coordinate production and documentation. Ask us to identify the proposed shop and document its required qualifications in the quote before you order.

What it is: We are a managed manufacturing and sourcing partner for U.S. hardware companies. Our engineers review each part's process, material, tolerance, quality, and schedule requirements, then match the work with vetted U.S. manufacturers. We coordinate production, inspection documentation, and delivery in one platform, while you can see and communicate with the shop making your part. Vendra states that it holds AS9100 certification, while supplier certifications vary. If your order requires an AS9100-certified manufacturer, verify the proposed shop’s certificate, site, and scope before placing the order. Vendra’s certificate does not replace the shop’s.

Capabilities and evidence: We state that Vendra is ITAR registered and holds CAGE code 11FY0. Before publication, verify any claims about U.S.-person access controls, supplier access decisions, and AWS GovCloud hosting against current Vendra documentation. Do not treat those controls as established by the linked defense page unless it explicitly describes them. Registration and hosting alone do not authorize every technical-data transfer or establish contract-specific security compliance. Before sharing files, confirm the classification, permitted recipients, required authorizations, and order terms with your compliance team and ours.

Tell us which material and process certificates, inspection records, and traceability your order requires so we can include them in the RFQ and quote. AS9102 first-article inspection reports are available on request, not automatically included with every order. Ask us to identify the proposed shop’s qualifications and include the agreed report scope and delivery terms in the quote before issuing the purchase order.

In our AstroForge customer story, describe the specific parts, manufacturing work, and Vendra coordination that the published account verifies. Keep any prototype-to-flight-hardware claim limited to what AstroForge’s story establishes; assess capacity and delivery separately for each new order.

Pricing: Request a quote to confirm current platform fees and order terms. Submit an RFQ for part-specific pricing that includes the inspection and documentation your order needs.

#Protolabs

Best for: Aerospace buyers seeking rapid prototypes or low-volume production through Protolabs. Confirm whether its own operations or Protolabs Network will make the part.

What it is: Protolabs offers machining through its own operations and the Protolabs Network. Its aerospace CNC page lists ISO 9001:2015, ISO 13485:2016, AS9100D, and ITAR. Confirm which facility will make your part and which listed credentials apply to that facility and service.

Pros: Protolabs lists 3- and 5-axis milling, turning, and quality documentation on its aerospace CNC page. Protolabs reports more than 95% on-time delivery. The cited page does not identify the measurement period or orders counted, so the figure cannot be compared directly with a commitment for your order. Confirm your delivery date and applicable terms in the quote rather than treating that company-reported figure as an order commitment.

Cons: Protolabs markets additional processes through its network, but its certification banner does not establish that every network shop or process holds the same credentials. Confirm the production site, certification scope, and required records before ordering.

Pricing: Protolabs provides quotes rather than published aerospace-specific pricing tiers.

#Xometry

Best for: Buyers who want instant CNC quoting and network-based sourcing, provided they confirm the assigned production site and requirements for controlled data.

What it is: Xometry uses a manufacturing partner network to quote and source CNC parts. Its aerospace CNC page states that Xometry reports AS9100D certification, ITAR registration, and Cybersecurity Maturity Model Certification (CMMC) Level 2 status. Ask Xometry for the applicable certificate, registration evidence, and CMMC record. Before placing an order, confirm the holder and scope of each credential and determine which requirements apply to the assigned production site. Those provider statements do not establish the certification scope or controlled-data permissions of every partner.

Pros: Xometry offers instant quoting and states on its aerospace CNC page that its First Article Inspection Reports use AS9102 forms. That describes the report format. It does not mean Xometry performs a first-article inspection on every order.

Cons: Xometry describes a global supplier network on its aerospace CNC page. Confirm U.S. production and controlled-data handling for your order. For any certification your order requires, request the certificate and verify its holder, site, and scope. A statement of compliance is not a certificate.

Pricing: Xometry generates order-specific quotes rather than publishing a fixed aerospace CNC price. An instant quote does not establish the final requirements for inspection or documentation.

#Fictiv

Best for: Buyers who want network-based sourcing and can verify the assigned shop’s location, credentials, and inspection deliverables with Fictiv before ordering.

What it is: Fictiv describes a network that includes AS9100-certified manufacturers. Its aerospace article discusses projects for Heliospace and Honeywell, but those projects do not establish the assigned shop’s credentials or delivery date for a new order.

Capabilities: Ask Fictiv to identify a shop that can machine your part to its specified tolerances and provide the required inspection records.

Cons: Confirm the assigned production site for any U.S.-only requirement; Fictiv’s office locations do not establish where your part will be made. The cited article does not establish whether Fictiv holds entity-level AS9100D certification or ITAR registration, or whether every network supplier holds either credential. Before sharing controlled technical data, ask Fictiv to identify the intended recipients and their access controls.

Pricing: Request a quote for the part and its required documentation. The cited article does not establish an aerospace-specific price or standard lead time.

#Compare provider models and order-level requirements

Use the table to shortlist providers, then ask each for a proposed production site and an order-specific quote. Compare certificate scope, controlled-data access, inspection deliverables, tolerances, capacity, and delivery terms against the same part requirements.

#Verify certification and order deliverables

Verify the AS9100D certificate for the entity and site whose certified activities will cover your part. Use the IAQG OASIS database to check the certificate holder, current status, listed site, and AS9100D scope. For network orders, check the proposed production shop’s certificate separately from the provider’s certificate.

For ITAR-controlled work, identify the entity that would receive the technical data and ask your compliance contact to confirm whether DDTC registration or separate authorization is required. Request evidence of any required registration and confirm its status. Ask who can access your drawings during quoting and production, including subcontractors. Registration alone does not authorize every transfer or shipment.

Specify inspection deliverables in the purchase order. If your program requires an AS9102 First Article Inspection Report, name the applicable part revision, report format, submission timing, and approval requirement. Do not assume the supplier includes an FAI because it advertises inspection or uses AS9102 forms for reports.

Before sending a DoD RFQ containing CUI, confirm the applicable DFARS clauses and Cybersecurity Maturity Model Certification (CMMC) requirements with your contracting or compliance contact. Those requirements may impose cybersecurity controls in addition to any ITAR controls.

#When Vendra’s managed network fits

Vendra is a fit to evaluate when a U.S.-made part needs supplier coordination and specified inspection records. Our engineers review the part requirements and match work with U.S. manufacturers, while the platform keeps the RFQ, production communication, and documentation together. For regulated work, ask us to identify the proposed shop and document its required qualifications and deliverables in the quote.

If a later build needs another process or more capacity, we can assess a different U.S. shop. Before approving a supplier change, verify the proposed shop’s qualifications and agree on inspection records and delivery terms for the new order.

Submit an RFQ to Vendra with your drawings, delivery target, and inspection requirements. We’ll review the part and discuss a suitable U.S. manufacturing option with you.

#FAQs

Is AS9100D required for every aerospace part? No universal rule makes AS9100D mandatory for every part. Your customer contract and purchase order determine the requirements for a specific program. If AS9100D applies, check the certificate holder, manufacturing site, scope, and validity in the IAQG OASIS database.

Does ITAR registration alone authorize a supplier to handle controlled technical data? No. Registration does not, by itself, authorize every transfer or establish that a supplier controls access to your files. Confirm the export classification with your compliance contact before sharing drawings or CAD files. Then establish who can access them, where they will be stored, and whether any transfer requires separate authorization.

Does an aerospace CNC order automatically include an AS9102 First Article Inspection? Do not assume it does. Specify the required inspection and First Article Inspection Report in your purchase order, including the applicable AS9102 revision and any customer forms. Confirm that the quote prices the report and states when the supplier will submit it.

Does a network’s certification cover every machine shop in it? No. A platform’s credential and a shop’s credential belong to their respective certificate holders. Ask which company will machine your part, then verify that site’s certificate and scope for the work you are buying.

How quickly should you expect an aerospace CNC quote? None of the provider information above establishes a comparable turnaround time for an aerospace quote. Ask each provider for a quote date after supplying the drawings, material, inspection requirements, and export classification. Confirm the production site and required records in the final quote.
