Common ITAR Violations in Aerospace Supply Chains

Key Takeaways

• Unauthorized sharing of ITAR-controlled technical data with foreign nationals or unapproved parties is the top violation and demands strict U.S. person access controls plus DDTC authorization.

• Deemed exports occur when foreign nationals access controlled data in the U.S. and are preventable through licensing, verification, and facility controls.

• Supplier screening failures create cascading risks for OEMs, so you must conduct due diligence, DDTC checks, and restricted party screenings for every tier.

• Misclassification of ITAR vs. EAR items can produce massive fines, such as RTX’s $200 million penalty, so submit commodity jurisdiction requests and document decisions.

• Partner with Precision Advanced Manufacturing, your ITAR-registered ally, for compliant precision components that reduce supply chain exposure.

9 Common ITAR Violations in Aerospace Manufacturing Supply Chains

1. Unauthorized Technical Data Sharing

Unauthorized technical data sharing occurs when aerospace suppliers send drawings, specifications, or manufacturing data to parties who lack approval. Quadrant Magnetics faced criminal charges for unlawful transmission of technical drawings to China through supply chain channels. This type of violation often involves CAD files, process specifications, or quality documentation sent to foreign subcontractors or consultants without DDTC authorization.

Build a layered control structure that governs every technical data exchange.

• Establish written technical data sharing protocols that require DDTC authorization as the baseline policy for all projects.

• Within that framework, restrict access to ITAR-controlled technical data to verified U.S. persons through documented screening.

• Support these rules with secure, auditable file-sharing systems that provide granular access controls and activity logs.

• Add another layer of protection by requiring signed non-disclosure agreements before any technical discussions, even with approved U.S. persons.

2. Deemed Exports to Foreign Nationals

Deemed exports rank among the most frequent ITAR violations in aerospace supply chains. ITAR foreign national access violations, known as deemed exports, occur when organizations fail to obtain licenses before foreign nationals access controlled technical data, even at U.S. facilities.

Typical scenarios include foreign engineers, technicians, or consultants entering controlled areas or viewing ITAR documentation without proper licensing.

Create a clear process that manages foreign national access from hiring through daily operations.

• Verify U.S. person status before granting facility or data access and keep that verification on file.

• Secure deemed export licenses for foreign national employees or contractors who require exposure to controlled data.

• Use physical and digital access controls to separate ITAR-controlled areas and systems from general workspaces.

• Train security and reception personnel on foreign national identification requirements and escalation procedures.

3. Supplier Screening Failures

Supplier screening failures expose aerospace OEMs to liability when tier-2 and tier-3 suppliers lack ITAR controls. U.S. export authorities hold aerospace OEMs and Tier 1 contractors accountable for supply chain failures by Tier 2 and Tier 3 suppliers, requiring auditable supplier screening and oversight.

Weak vetting of subcontractors, distributors, and service providers allows violations to spread through the entire chain. Reduce this risk by treating supplier compliance as a core qualification, not a checkbox.

Avoid these pitfalls with Precision Advanced Manufacturing’s certified processes, and get a compliance-focused quote today.

• Conduct comprehensive due diligence on every supply chain participant and document the review.

• Confirm DDTC registration status for all suppliers involved with ITAR-controlled work.

• Screen suppliers against restricted party lists such as the BIS Entity List and OFAC SDN List.

• Maintain auditable records that show when screening occurred, what tools you used, and the results.

4. Misclassification of ITAR vs. EAR Items

Misclassification occurs when defense articles are treated as EAR-controlled commercial items instead of ITAR-controlled defense items. RTX Corporation settled for $200 million in penalties primarily due to misclassification of defense articles that resulted in unauthorized exports to China. Many suppliers assume commercial aerospace components fall under EAR and skip a full jurisdictional analysis.

Build a repeatable classification process that does not rely on assumptions.

• Submit Commodity Jurisdiction requests to DDTC when the item status is unclear or disputed.

• Keep current references for USML category definitions and train engineers on key thresholds.

• Run classification reviews for every new product and for major design changes.

• Document each classification decision, including rationale, references, and approvers.

5. Unsecured Data Transfers and Cloud Storage

Unsecured data transfers and cloud storage create hidden ITAR export risks in modern aerospace collaboration. Common ITAR compliance failures in cloud-based ERP systems include backups stored in non-U.S. data centers, admin privileges granted without U.S. person verification, and file-sharing tools that expose controlled data to unauthorized users. Email attachments, unmanaged file-sharing links, and non-compliant cloud platforms can all result in inadvertent exports.

Design your digital environment so that controlled data never leaves compliant channels.

• Select FedRAMP-authorized cloud providers that guarantee U.S. data residency for ITAR workloads.

• Encrypt all ITAR-controlled data transfers, including backups and system integrations.

• Limit cloud access to verified U.S. persons and review those permissions regularly.

• Perform scheduled audits of data storage locations and transfer methods to confirm compliance.

6. Recordkeeping and Reporting Lapses

Recordkeeping lapses undermine ITAR compliance even when daily practices appear sound. DDTC and BIS regulators view lack of documentation on supplier screening, including who was screened, when, how, and results, as non-compliance in ITAR and EAR audits, regardless of intent. Missing export licenses, incomplete shipping paperwork, and weak transaction records all raise red flags.

Create documentation habits that prove your controls work in practice.

• Maintain comprehensive records for at least the required five-year retention period.

• Capture every classification decision and license application in a central system.

• Use automated recordkeeping tools that provide timestamps and audit trails.

• Schedule periodic internal audits to test documentation completeness and accuracy.

7. Unlicensed Brokering and Shipping

Unlicensed brokering and shipping occur when organizations move defense articles or provide related services without DDTC authorization.

Unlicensed exports represent a major category of ITAR violations, occurring when organizations ship defense articles, transfer technical data, or provide defense services without obtaining required DDTC authorization. Freight forwarders, logistics providers, and intermediaries often sit at the center of these violations.

Integrate logistics partners into your export control program instead of treating them as separate.

• Confirm that all logistics providers understand ITAR requirements and maintain documented compliance capabilities.

• Secure required export licenses before shipping any defense articles or related technical data.

• Screen every intermediary, routing point, and destination against restricted party and embargo lists.

• Use pre-shipment compliance checks to verify licenses, documentation, and routing details.

8. Unauthorized Re-Exports by Suppliers

Unauthorized re-exports occur when foreign suppliers or subsidiaries transfer U.S.-origin defense articles or technical data without approval. ITAR’s extraterritorial jurisdiction applies to non-U.S. aerospace companies handling U.S.-origin defense articles, components, technology, or software, including in re-exports and cloud-based engineering collaboration. Once items leave the United States, oversight often weakens, which increases risk.

Extend your compliance expectations beyond first-tier partners and into downstream transfers.

• Include clear ITAR compliance clauses and re-export restrictions in all supplier agreements.

• Monitor downstream transfers and perform end-use verification where practical.

• Require suppliers to obtain re-export authorization for any controlled transfers they initiate.

• Conduct recurring supplier compliance assessments that review both paperwork and actual practices.

9. Failure to Register as Manufacturer

Failure to register as a manufacturer occurs when producers of USML-listed items operate without DDTC registration. Failing to register with the Directorate of Defense Trade Controls (DDTC) is a common ITAR violation; producers of USML-listed items must register even without intent to export. Many aerospace suppliers incorrectly assume only direct exporters need to register.

Address registration at the start of every defense-related manufacturing program.

• Register with DDTC before manufacturing any USML-listed items or components.

• Keep registration current with timely annual renewals and internal reminders.

• Track USML changes that could bring existing products under registration requirements.

• Embed registration checks into new product introduction and contract review workflows.
