This includes blueprints, drawings, photographs, plans, instructions and documentation.<\/p>\n<p>Common ITAR violations in CNC and machining environments fall into three categories: improper disclosure, weak safeguards and documentation failures.<\/p>\n<p>Disclosure violations include transferring or disclosing controlled files to a foreign national inside the United States without a license under <a href=\"https:\/\/ecfr.gov\/current\/title-22\/chapter-I\/subchapter-M\/part-120\/section-120.17\" target=\"_blank\" rel=\"noindex nofollow\">22 CFR 120.17<\/a>, sending ITAR-controlled data to denied or restricted parties and allowing unescorted foreign national visitors into areas where controlled data is visible or accessible.<\/p>\n<p>Safeguard failures include storing controlled files on unencrypted or shared drives accessible to non-U.S. persons and exporting or attempting to export technical data without DDTC authorization, prohibited under <a href=\"https:\/\/ecfr.gov\/current\/title-22\/chapter-I\/subchapter-M\/part-127\/section-127.1\" target=\"_blank\" rel=\"noindex nofollow\">22 CFR 127.1(a)(1)<\/a>.<\/p>\n<p>Documentation failures include not maintaining records for the required retention period.<\/p>\n<p>Precision Advanced Manufacturing operates under these certified quality management systems and applies them to controlled CNC programs.<\/p>\n<h2>CAD, CAM, G-Code and Setup Files as ITAR Technical Data<\/h2>\n<p>The violations above often stem from confusion about which CNC files qualify as technical data. Every digital file generated or used to produce a defense article can constitute technical data under <a href=\"https:\/\/ecfr.gov\/current\/title-22\/chapter-I\/subchapter-M\/part-120\/section-120.10\" target=\"_blank\" rel=\"noindex nofollow\">22 CFR 120.10<\/a>. The following checklist maps common CNC file types to that definition.<\/p>\n<ol>\n<li><strong>CAD models (.STEP, .IGES, .SolidWorks, .CATIA):<\/strong> These files contain geometry, tolerances and material callouts required for manufacture of a defense article. They are classified as technical data.<\/li>\n<li><strong>CAM toolpath files:<\/strong> These files encode cutting strategies, feeds, speeds and fixturing logic needed to produce a controlled part. They are classified as technical data.<\/li>\n<li><strong>G-code programs:<\/strong> These machine-readable instructions directly drive production of a defense article. G-code derived from a controlled CAD model carries the same classification as the source data.<\/li>\n<li><strong>Setup sheets and work instructions:<\/strong> These documents capture fixturing, tooling, inspection steps and process parameters specific to a controlled part. They are classified as technical data.<\/li>\n<li><strong>Inspection and first-article reports:<\/strong> These records contain dimensional data and material certifications tied to a defense article. They are classified as technical data.<\/li>\n<li><strong>Technical data related to Significant Military Equipment (SME):<\/strong> Under <a href=\"https:\/\/ecfr.gov\/current\/title-22\/chapter-I\/subchapter-M\/part-120\/section-120.10\" target=\"_blank\" rel=\"noindex nofollow\">22 CFR 120.10(c)<\/a>, manufacturing data directly related to an SME-designated article is itself designated SME and carries heightened controls.<\/li>\n<\/ol>\n<h2>U.S. Person Access Rules on the CNC Shop Floor<\/h2>\n<p>Under <a href=\"https:\/\/ecfr.gov\/current\/title-22\/chapter-I\/subchapter-M\/part-120\/section-120.17\" target=\"_blank\" rel=\"noindex nofollow\">22 CFR 120.17<\/a>, disclosure of controlled technical data to a non-U.S. person inside the United States counts as an export. <a href=\"https:\/\/ecfr.gov\/current\/title-22\/chapter-I\/subchapter-M\/part-120\" target=\"_blank\" rel=\"noindex nofollow\">22 CFR 120.62<\/a> defines a U.S. person as a U.S. citizen, U.S. national, lawful permanent resident or a protected individual under 8 U.S.C. 1324b(a)(3). Organizations incorporated under U.S. law also qualify.<\/p>\n<p>The following access-control checklist applies to all personnel with exposure to ITAR-controlled CNC files or hardware.<\/p>\n<ol>\n<li>Verify U.S. person status for every employee, contractor and temporary worker before granting access to controlled data or areas. Acceptable evidence includes a U.S. passport, U.S. birth certificate or permanent resident card.<\/li>\n<li>Conduct verification separately from Form I-9 employment eligibility checks, even when some documents satisfy both requirements.<\/li>\n<li>Restrict ITAR-controlled CNC workstations, file servers and program storage to U.S. persons unless a valid export license or exemption is in place.<\/li>\n<li>Document U.S. person status in personnel files and retain records for DDTC inspection.<\/li>\n<li>Screen all personnel against the Consolidated Screening List before granting access.<\/li>\n<li>Assign role-based access so machinists, programmers and quality engineers receive only the controlled files required for their specific tasks.<\/li>\n<\/ol>\n<h2>Secure Storage and Transfer of CNC Technical Files<\/h2>\n<p>Verifying who can access controlled data addresses only part of the risk. Controlled CNC files must also be protected both at rest and in transit. <a href=\"https:\/\/csrc.nist.gov\/publications\/detail\/fips\/140\/3\/final\" target=\"_blank\" rel=\"noindex nofollow\">NIST FIPS 140-3<\/a> is the current U.S. government standard for cryptographic modules and defines four security levels covering physical security, authentication and sensitive parameter management. Using FIPS 140-3 validated encryption strengthens a CNC shop&#8217;s technical data protection program for file transfer, cloud storage and backup systems.<\/p>\n<ol>\n<li>Encrypt all controlled CNC files at rest using FIPS 140-3 validated cryptographic modules.<\/li>\n<li>Encrypt all file transfers, including CAD, CAM, G-code and setup sheets, using FIPS 140-3 validated protocols. Do not transmit controlled data over unencrypted email or consumer file-sharing services.<\/li>\n<li>Restrict cloud storage of controlled data to U.S.-based, ITAR-compliant platforms with access controls limited to U.S. persons.<\/li>\n<li>Segment CNC programming networks from general corporate networks and the internet.<\/li>\n<li>Log all access to controlled file repositories with timestamps, user identity and file names. Retain logs for a minimum of five years per <a href=\"https:\/\/ecfr.gov\/current\/title-22\/chapter-I\/subchapter-M\/part-122\" target=\"_blank\" rel=\"noindex nofollow\">22 CFR 122.5(a)<\/a>.<\/li>\n<li>Disable removable media ports on CNC programming workstations or enforce encrypted-media-only policies.<\/li>\n<\/ol>\n<h2>Physical Shop-Floor Controls and Visitor Procedures<\/h2>\n<p>Physical access to areas where ITAR-controlled articles or technical data are present requires the same rigor as digital controls. Under <a href=\"https:\/\/ecfr.gov\/current\/title-22\/chapter-I\/subchapter-M\/part-126\/section-126.13\" target=\"_blank\" rel=\"noindex nofollow\">22 CFR 126.13(c)<\/a>, a technology control plan supports processing of ITAR license applications when foreign nationals are present at a facility.<\/p>\n<ol>\n<li>Designate and physically demarcate ITAR-controlled zones on the shop floor. Post clear signage at zone boundaries.<\/li>\n<li>Require badge-based or keycard access to controlled zones, limited to verified U.S. persons.<\/li>\n<li>Obtain documented pre-arrival approval for all visitors before granting facility access.<\/li>\n<li>Verify every visitor&#8217;s identity through government-issued ID or passport scanning upon arrival.<\/li>\n<li>Confirm citizenship or residency status to establish U.S. person designation before allowing access to controlled areas.<\/li>\n<li>Screen all visitors against denied and restricted party lists before entry.<\/li>\n<li>Escort all non-U.S. persons and unverified visitors at all times within the facility. Escorts must be U.S. persons with ITAR awareness training.<\/li>\n<li>Collect and retain signed NDAs or compliance acknowledgments tied to each visit record.<\/li>\n<li>Maintain detailed visitor logs capturing name, arrival and departure times, purpose, areas accessed, approving authority and documents signed. Retain logs for DDTC inspection.<\/li>\n<li>Apply the same identity verification, screening and access controls to contractors, auditors and vendors as to external visitors.<\/li>\n<\/ol>\n<p>Precision Advanced Manufacturing&#8217;s integrated single-facility operations in California and Texas consolidate machining, fabrication, finishing and quality inspection under controlled access.

Under <a href=\"https:\/\/ecfr.gov\/current\/title-22\/chapter-I\/subchapter-M\/part-122\" target=\"_blank\" rel=\"noindex nofollow\">22 CFR 122.1(a)<\/a>, a single occasion of manufacturing is sufficient to trigger the registration requirement.<\/p>\n<p>Registration functions as an administrative prerequisite. It does not confer export rights or authorize the transfer of technical data. Separate licenses or approvals from DDTC remain required for any export or deemed export.<\/p>\n<p>ITAR registrants must maintain records concerning the manufacture, acquisition and disposition of defense articles and technical data for a minimum of five years from the expiration of the relevant license or transaction date. Electronic records must be legible, unalterable and reproducible on paper per <a href=\"https:\/\/ecfr.gov\/current\/title-22\/chapter-I\/subchapter-M\/part-122\" target=\"_blank\" rel=\"noindex nofollow\">22 CFR 122.5(a)<\/a>.<\/p>\n<p>As an ITAR registrant, Precision Advanced Manufacturing maintains full documentation and traceability across controlled programs, supporting audit readiness at every production stage.<\/p>\n<h2>ITAR Compliance Checklist for CNC Supplier Evaluation<\/h2>\n<p>Procurement managers and supplier quality engineers can use the following consolidated checklist to evaluate CNC suppliers for ITAR-controlled programs.<\/p>\n<ol>\n<li><strong>DDTC registration:<\/strong> Confirm the supplier holds active ITAR registration under 22 CFR Part 122.<\/li>\n<li><strong>Quality certifications:<\/strong> Verify AS9100D and ISO 9001:2015 registrations, with defined quality checkpoints and full documentation on every program.<\/li>\n<li><strong>U.S. person workforce:<\/strong> Confirm all personnel with access to controlled data and hardware are verified U.S. persons with documented status on file.<\/li>\n<li><strong>File classification procedures:<\/strong> Confirm the supplier classifies CAD models, CAM toolpaths, G-code, setup sheets and inspection records as ITAR technical data and applies corresponding controls.<\/li>\n<li><strong>Encrypted storage and transmission:<\/strong> Confirm FIPS 140-3 validated encryption protects controlled files at rest and in transit.<\/li>\n<li><strong>Network segmentation:<\/strong> Confirm CNC programming networks are isolated from general corporate and internet-facing systems.<\/li>\n<li><strong>Physical zone controls:<\/strong> Confirm ITAR-controlled zones are demarcated, badged and restricted to U.S. persons.<\/li>\n<li><strong>Visitor management:<\/strong> Confirm pre-arrival approval, identity verification, party screening, escorted access and signed compliance acknowledgments are standard practice.<\/li>\n<li><strong>Five-year record retention:<\/strong> Confirm electronic records are maintained in a legible, unalterable and reproducible format for the required period.<\/li>\n<li><strong>Multi-axis CNC capability:<\/strong> Confirm the supplier&#8217;s equipment and programming expertise support the complexity of the controlled program. Precision Advanced Manufacturing&#8217;s integrated multi-axis CNC machining handles complex, tight-tolerance defense components from prototype through full-rate production.<\/li>\n<li><strong>Traceability:<\/strong> Confirm full material and process traceability is documented and available for customer and government audit.<\/li>\n<li><strong>Scalability:<\/strong> Confirm the supplier can transition from prototype to full-rate production without a change in quality systems or compliance posture. Precision Advanced Manufacturing&#8217;s multi-shift operations support this transition under the same certified systems.<\/li>\n<\/ol>\n<h2>Request a Quote for ITAR-Controlled CNC Programs<\/h2>\n<p>Precision Advanced Manufacturing is an ITAR-registered, AS9100D and ISO 9001:2015 certified CNC machining and fabrication provider. Operations in California and Texas support defense, aerospace, space and UAV programs that require tight tolerances, full traceability and verified regulatory compliance. All controlled programs run under documented access controls, encrypted data systems and a U.S. person workforce.<\/p>\n<p>Connect with Precision Advanced Manufacturing&#8217;s team to define the specifications, certifications and production strategy for the next controlled program.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<h3>Does G-code count as ITAR technical data?<\/h3>\n<p>G-code generated from a controlled CAD model to produce a defense article qualifies as technical data under 22 CFR 120.10. It encodes the specific instructions required to manufacture a controlled part and must be stored, transmitted and accessed under the same controls as the source design files. Treating G-code as uncontrolled creates a common compliance gap in CNC environments.<\/p>\n<h3>What is a deemed export under ITAR and how does it apply to a machine shop?<\/h3>\n<p>A deemed export occurs when controlled technical data is disclosed to a foreign national inside the United States. In a machine shop, this includes allowing a non-U.S. person to view a CAD model, access a CNC program, read a setup sheet or enter a controlled production area where defense articles or related data are present. No physical shipment is required for a deemed export violation. Shops must verify U.S. person status for all employees, contractors and visitors before granting any access to controlled data or hardware.<\/p>\n<h3>What certifications should a CNC supplier hold for ITAR-controlled defense programs?<\/h3>\n<p>At minimum, a CNC supplier should hold active ITAR registration with the Directorate of Defense Trade Controls and operate under an AS9100D certified quality management system. ISO 9001:2015 registration provides additional process discipline. These certifications confirm that the supplier maintains documented procedures, traceability, inspection reporting and quality checkpoints aligned with aerospace and defense program requirements. Certification alone does not satisfy ITAR obligations. The supplier must also demonstrate active access controls, encrypted data handling and a verified U.S. person workforce.<\/p>\n<h3>How long must an ITAR-registered CNC shop retain records?<\/h3>\n<p>ITAR registrants must retain records related to the manufacture, acquisition and disposition of defense articles and technical data for a minimum of five years from the expiration of the relevant license or transaction date. Electronic records must be legible, unalterable and reproducible on paper. This requirement covers CNC program files, inspection records, visitor logs, personnel verification documents and any correspondence related to controlled programs.<\/p>\n<h3>What is the difference between ITAR registration and an export license?<\/h3>\n<p>ITAR registration under 22 CFR Part 122 is an administrative requirement for any U.S. person or company that manufactures defense articles or furnishes related technical data. Registration does not authorize the export of technical data or defense articles. A separate license or written approval from the Directorate of Defense Trade Controls is required before any export or deemed export of controlled data can occur. A CNC supplier that is registered but lacks the required license for a specific transaction remains in violation of <a href=\"https:\/\/ecfr.gov\/current\/title-22\/chapter-I\/subchapter-M\/part-127\/section-127.1\" target=\"_blank\" rel=\"noindex nofollow\">22 CFR 127.1<\/a> if a controlled transfer takes place.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Learn how ITAR technical data rules apply to CNC files and shop-floor controls.
