Procurement managers, supplier quality engineers and program managers can apply it when evaluating any ITAR-registered machining partner. The first requirement establishes the legal foundation for all other controls.<\/p>\n<h3>Maintain Active DDTC Registration<\/h3>\n<p>Any company that manufactures defense articles must register with DDTC under 22 CFR 122.1, even when producing solely for domestic sale. Registration requires a DECCS account, a completed DS-2032 form and payment of the applicable annual fee. Registration must be renewed each year, and a lapse during defense article production constitutes an ITAR violation. Precision Advanced Manufacturing holds active ITAR registration across California and Texas facilities, covering machining, fabrication and finishing operations within AS9100D and ISO 9001:2015 quality systems.<\/p>\n<h3>Develop and Maintain a Written Technology Control Plan<\/h3>\n<p>A Technology Control Plan (TCP) documents how controlled technical data is stored, accessed, transmitted and disposed of. DDTC does not prescribe a standard TCP format, so each plan must reflect actual operations, facility layout, workforce composition and data environment. Generic language that does not match real procedures is a leading cause of TCP rejection. To avoid this pitfall, Precision Advanced Manufacturing tailors its TCP to a multi-axis CNC machining and fabrication environment, with controls specific to each production cell and data system.<\/p>\n<h3>Enforce U.S.-Person Access Controls on the Shop Floor<\/h3>\n<p>U.S.-person access controls must operate through concrete mechanisms on the shop floor, not only through HR policy. Effective controls include badge-restricted production areas, role-based system access, visitor escort procedures and foreign national screening. Contractors must screen employees, visitors, vendors and subcontractors to prevent unauthorized access to ITAR-controlled technical data by foreign persons. Precision Advanced Manufacturing applies physical access controls to all areas where controlled drawings, programs and hardware are present.<\/p>\n<h3>Implement Information Security and Network Segregation<\/h3>\n<p>When ITAR and non-ITAR work coexist, a TCP must show physical and network segregation such as separate servers, restricted folders, badge-controlled production areas or dedicated program cells. Information technology controls include network segmentation, role-based access, authentication, encryption and audit logs. Cloud computing controls must address cloud service provider selection, server location verification, encryption key management and contractual obligations that support ITAR compliance. Precision Advanced Manufacturing maintains segregated data environments for controlled programs, with access limited to authorized U.S. persons.<\/p>\n<h3>Conduct Documented ITAR Training<\/h3>\n<p>A TCP must specify who receives ITAR training, how often it occurs, what content it covers and how completion is documented. Annual refreshers serve as the minimum standard. Training records must cover machinists, quality inspectors and engineers who handle controlled technical data. Precision Advanced Manufacturing maintains training logs for all personnel with access to ITAR-controlled programs, with records retained according to regulatory requirements.<\/p>\n<h3>Screen Subcontractors and Flow Down Compliance Obligations<\/h3>\n<p>Before granting access to ITAR technical data, prime contractors must request proof of current DDTC registration from subcontractors and screen them against applicable restricted-party lists. Every subcontract involving ITAR-controlled items or data must include explicit ITAR compliance obligations and flowdown provisions. Vendors require re-screening at contract renewal, after ownership changes and when new purchase orders are issued for high-risk suppliers. Precision Advanced Manufacturing applies these screening and flowdown requirements to all suppliers and service providers involved in controlled programs.<\/p>\n<h3>Maintain Five-Year Records and Traceability<\/h3>\n<p>ITAR registrants must maintain comprehensive records of all defense trade activities for five years. A TCP must incorporate supply chain traceability requirements that allow a part to be traced back through every process step, operator and material lot. Precision Advanced Manufacturing uses an AS9100D quality system to provide full traceability across materials, processes and inspection records for every controlled component.<\/p>\n<h3>Technology Control Plan Elements for Machine Shops<\/h3>\n<p>A compliant TCP for a precision machining environment typically includes these elements:<\/p>\n<ul>\n<li>Scope and purpose statement referencing specific USML categories, contract numbers and 22 CFR Parts 120\u2013130<\/li>\n<li>Identification of controlled technology, including technical data, hardware, software and defense services covered<\/li>\n<li>Personnel access controls, including U.S.-person verification, foreign national access approval workflow and access logs<\/li>\n<li>Physical security measures such as restricted area designation, visitor badging and escort procedures and locked storage for controlled documents and hardware<\/li>\n<li>Information security measures such as network segmentation, role-based access, encryption at rest and in transit, cloud controls and audit logs<\/li>\n<li>ITAR marking and labeling protocols for controlled documents, drawings and media<\/li>\n<li>Training requirements that define who receives training, frequency, content and completion documentation<\/li>\n<li>Subcontractor and vendor screening, including DDTC registration verification, denied-party screening and ITAR flowdown in purchase orders<\/li>\n<li>Recordkeeping requirements covering five-year retention, records custodian, storage location and audit procedures<\/li>\n<li>Incident response procedures that define unauthorized disclosure, escalation paths and voluntary self-disclosure steps<\/li>\n<li>Named responsible official accountable for TCP implementation and compliance oversight<\/li>\n<li>Review and update cadence that keeps the TCP aligned with operational changes<\/li>\n<\/ul>\n<h2>Common ITAR Violations in Aerospace Machining<\/h2>\n<p>Unauthorized exports represent the most fundamental ITAR violation and appear frequently in DDTC enforcement actions. These violations include physical shipments of defense hardware, electronic transmissions of technical data, oral or written disclosures to foreign nationals and provision of defense services without an approved Technical Assistance Agreement or Manufacturing License Agreement.<\/p>\n<p>Typical violation categories in aerospace machining environments include:<\/p>\n<ul>\n<li><strong>Unauthorized exports of technical data:<\/strong> Sharing controlled drawings, CNC programs or specifications with foreign nationals without authorization, including through email, screen sharing or facility tours<\/li>\n<li><strong>Registration failures:<\/strong> Manufacturing or exporting defense articles without active DDTC registration, even when no export has occurred<\/li>\n<li><strong>Agreement violations:<\/strong> Activities that deviate from the scope of an approved TAA, MLA or other DDTC authorization<\/li>\n<li><strong>Retransfer violations:<\/strong> A foreign recipient transferring U.S.-origin defense articles or technical data to a third party without required U.S. government approval, which can expose the original exporter to liability<\/li>\n<li><strong>Failure to report material changes:<\/strong> Not notifying DDTC of changes to registration information, ownership or operations<\/li>\n<\/ul>\n<p>Recent enforcement actions show the scale of potential penalties. DDTC imposed a $36 million civil penalty on General Electric Company under a consent agreement for 116 ITAR violations between 2018 and 2024, including unauthorized exports of technical data related to the F-35 and F414 military aircraft engines to the People&#039;s Republic of China. Boeing and 3D Systems Corporation faced similar enforcement actions in 2024 and 2023 respectively, with 3D Systems accepting a $20 million settlement. The maximum civil penalty can exceed $1 million per violation, and criminal penalties can reach 20 years imprisonment for willful violations.<\/p>\n<p><a href=\"https:\/\/precisionam.com\/request-a-quote\/\" target=\"_blank\">Request a quote<\/a> from an ITAR-registered machine shop with documented controls that address these common violation patterns.<\/p>\n<h2>ITAR and CMMC Requirements for Aerospace Suppliers<\/h2>\n<p>ITAR and CMMC address different risks in the defense supply chain and operate under separate legal frameworks. Mastery of both frameworks benefits suppliers that handle controlled technical data in Department of Defense programs.<\/p>\n<p><strong>Legal basis:<\/strong> ITAR functions as an export control law administered by the State Department under the Arms Export Control Act. CMMC operates as a Department of Defense cybersecurity certification program. CMMC does not authorize or prohibit disclosure of ITAR-controlled technical data.<\/p>\n<p><strong>Scope:<\/strong> ITAR focuses on who can receive controlled technical data and whether a transfer has authorization. CMMC focuses on whether a supplier&#039;s cybersecurity practices meet defined maturity levels for protecting Controlled Unclassified Information (CUI).<\/p>\n<p><strong>Personnel controls:<\/strong> ITAR requires U.S.-person verification for all individuals with access to controlled technical data and defense articles. CMMC does not impose nationality-based access restrictions but requires role-based access controls and user authentication under NIST SP 800-171.<\/p>\n<p><strong>Data protection:<\/strong> ITAR requires physical and network controls that prevent unauthorized disclosure to foreign persons. CMMC Level 2 requires FIPS-validated cryptography for CUI at rest and in transit, which can overlap with information security practices used to protect ITAR technical data.<\/p>\n<p><strong>Certification requirements:<\/strong> ITAR requires active DDTC registration renewed annually. <a href=\"https:\/\/www.deepfathom.ai\/articles\/cmmc-self-assessment-vs-c3pao\" target=\"_blank\" rel=\"noindex nofollow\">CMMC Level 2 assesses the 110 NIST SP 800-171 controls via either self-assessment or C3PAO third-party certification as required by contract, with annual affirmations of compliance.<\/a><\/p>\n<p>CUI includes export-controlled information, so some ITAR-related technical data may be treated as CUI in Department of Defense supply chains, creating overlap between the two frameworks at the data protection layer. Because of this overlap, suppliers that serve Department of Defense prime contractors may need to satisfy both regimes at the same time.<\/p>\n<h2>How Precision Advanced Manufacturing Applies the ITAR Checklist<\/h2>\n<p>Precision Advanced Manufacturing is a U.S.-based, ITAR-registered machining and fabrication provider operating under AS9100D and ISO 9001:2015 quality management systems.

This requirement covers export license applications and approvals, shipping documents, technical data transmittals, end-use certificates, DDTC correspondence, employee training records, classification determinations and TCP documentation. Records must remain retrievable, legible and auditable. Electronic records are acceptable when they meet these standards.<\/p>\n<h3>What is required to screen a subcontractor before sharing ITAR technical data?<\/h3>\n<p>Before sharing ITAR-controlled technical data with a subcontractor, a prime contractor must verify the subcontractor&#039;s active DDTC registration status and document that verification. The subcontractor must also be screened against applicable restricted-party and proscribed-countries lists. Every subcontract or purchase order involving controlled items or data must include explicit ITAR compliance obligations and flowdown provisions. Re-screening occurs at contract renewal, after changes in ownership or management and when new purchase orders are issued for high-risk suppliers. Screening records must be retained for at least five years.<\/p>\n<h3>How often must a Technology Control Plan be updated?<\/h3>\n<p>DDTC does not specify a mandatory update interval, but a TCP must stay aligned with actual operations. A TCP that describes procedures no longer in use, or that fails to address new data environments, personnel changes or facility modifications, will not satisfy DDTC examination requirements. Best practice is an annual TCP review, with updates whenever significant operational changes occur, such as new production areas, onboarding of foreign national employees, adoption of new cloud platforms or entry into new USML categories. A named responsible official should own the review and update process.<\/p>\n<h3>Does ITAR registration cover all work performed at a facility or only specific programs?<\/h3>\n<p>DDTC registration applies to the registrant as an entity, not to individual programs or contracts. A registered company must apply ITAR compliance controls, including the TCP, access controls, training and recordkeeping, across all operations that involve defense articles or controlled technical data, regardless of which contract generated the work. When ITAR and non-ITAR work coexist in the same facility, the TCP must show physical and network segregation that prevents unauthorized access to controlled items. Registration does not authorize exports, so separate DDTC authorizations are required for export transactions.<\/p>\n<h3>What triggers a DDTC investigation, and how do voluntary self-disclosures affect penalties?<\/h3>\n<p>DDTC investigations can begin with voluntary self-disclosures, referrals from the Department of Defense, intelligence agencies or Customs and Border Protection, third-party complaints and anomalies in export filing data. A significant share of enforcement actions starts with a company&#039;s voluntary self-disclosure. Voluntary disclosure, full cooperation and implementation of compliance improvements act as mitigating factors in penalty determinations. In the General Electric consent agreement, $18 million of a $36 million penalty was suspended on the condition that the funds support approved compliance enhancements. Voluntary self-disclosure does not remove penalties but consistently results in more favorable outcomes than violations discovered through external investigation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Precision Advanced Manufacturing breaks down ITAR compliant machining: DDTC registration, U.S.-person access, TCP and data security.
