Especially in the military sector, electronics development is subject to strict regulatory requirements. Two of the most important US regulations are theInternational Traffic in Arms RegulationsITAR)and thatDefense Federal Acquisition Regulation Supplement (DFARS). „ITAR Electronics“ thus means that the electronics contain components that are subject to ITAR rules. It is therefore strategically disadvantaged. If, on the other hand, electronics are „ITAR-free“, they are subject to weaker controls.

ITAR and DFARS govern the export, import, and handling of defense technology goods or information. Violations of these regulations can lead to severe legal and financial consequences for companies. In particular, the use of critical components with possibleDual-Use- Property (i.e., civilian and military use) presents challenges for designers and manufacturers. The two levels of regulation are as follows: ITAR and DFARS explained and the practical implications for printed circuit board (PCB) design and electronics production are presented. This article clarifies how DFARS and ITAR influence electronics design and manufacturing.
Regulatory Levels: ITAR and DFARS
International Traffic in Arms Regulations
The International Traffic in Arms Regulations are U.S. regulations administered by the U.S. State Department. They control the export, import, and domestic transfer of defense articles, defense services, and related technical data. ITAR specifically applies to items on the United States Munitions List, which includes a wide range of military equipment, weapons, and electronic components and systems for military and aviation applications. The ITAR regulation therefore enforces, among other things:
- Obtaining export licenses: For the export of controlled items or technologies, government approval must be obtained in advance. Example: The export of strong encryption software or radiation-hardened microprocessors requires a license.
- Technical Data Control: Construction drawings, parts lists, source codes, etc., pertaining to USML items may not be released without authorization toforeign nationalsbe passed on. Even sharing such data with a foreign national within the country is considereddeemed exportand requires an ITAR authorization.
- Registration and Record-keeping: Manufacturers or exporters of USML items must register with the responsible authority, the DDTC, and meticulously document all exports and transfers.
In summary, ITAR protects security-relevant technologies from uncontrolled export abroad. This also means that if an ITAR component is incorporated into another product, the entire end product is subject to ITAR regulations. ITAR compliance for a product thus means that the entire value chain consistently adheres to the requirements.
DFARS – Defense Supply Chain Security
The Defense Federal Acquisition Regulation Supplement is a set of regulations issued by the U.S. Department of Defense that supplements procurement regulations for defense contracts. DFARS is aimed at contractors and suppliers in the U.S. defense industry, ensuring that additional requirements are met in areas such as cybersecurity and supply chain protection. Key DFARS requirements include:
- Cybersecurity per NIST 800-171:Companies must implement controls to protect sensitive but unclassified information – such as multi-factor authentication, encryption, and security reviews – in accordance with the NIST SP 800-171 framework. This NIST cybersecurity standard is mandatorily anchored in DFARS for contractors and partially aligns with ISO/IEC 27001. In the future, the multi-tiered CMMC (Cybersecurity Maturity Model Certification) model will also be required to demonstrate cyber defense capabilities.
- Intellectual property protection and data rights:DFARS clauses require that contractors discloseData rightsrespect DoD and do not disclose or commercially exploit confidential technical data without authorization.
- Supply chain securityContractors must thoroughly vet and monitor their suppliers. This includes ensuring that subcontractors have adequate security practices and are not located in countries that pose a security risk. The risk ofCounterfeitThe use of counterfeit components in the supply chain must be minimized through quality control.
- Preference for small businesses:Regarding subcontracts, small business participation goals are to be met according to DFARS. Defense contracts often contain commitments to award subcontract shares to qualified small firms and to document this.
In summary, the aim ITAR refer to the control of defense materiel and their technical data, while DFARS is intended to ensure the secure handling of defense contracts, including cybersecurity and supplier management. Both levels overlap in the daily practice of electronics developers like PICKPLACE, who work for military customers.
Manufacturer Guidelines for Military Use of Components
Some manufacturers strictly prohibit the military use of their products. For example, it is forbiddenMuratain its export control policy the use of its products in the development, production, storage, or use of conventional weapons as well as weapons of mass destruction. Likewise, it calls forKioxiain its sales and delivery terms, customers assure that no products, technologies, or services will be used for weapons or military end-use applications. Violations entitle the company to withdraw from the contract.
Other manufacturers do not recommend use in military applications and disclaim liability for it. These notices are mostly generically worded and often include medical, aviation, or automotive applications in addition to military use.
For example, it introducesRohmin its terms and conditions that products are not designed for military purposes or other „special purposes“; Rohm assumes no liability for use in such areas unless a separate agreement has been made beforehand.Littelfusecomponents are not intended for applications such as military, medical, aerospace, or life support systems – warranties and manufacturer liability are void upon use. AlsoNexperiaindicates that its products are not authorized for military, medical, or safety-critical purposes; use in such areas is at the customer's own risk.
Why ITAR-free Electronics Are Preferred
For European manufacturers of dual-use technologies such as engines, ship propulsion systems, power supply systems, and industrial controls, the selection of electronics is increasingly becoming a strategic decision. The use of ITAR-regulated components can cause an entire product to fall under U.S. export control – even if development, production, and the customer are entirely outside the U.S.
ITAR-free electronics reduce this dependency and create more technical, economic, and political freedom of action.
Even individual US components classified under ITAR can have significant implications for export, service, maintenance, and international cooperation. This affects, for example, FPGA technologies, cryptographic modules, RF components, communication modules, or certain processors. If such a component is integrated into a system, technical data, software, bills of materials, or even support services can become regulatorily restricted.
This presents several risks for manufacturers:
- Export permits may be required even if the product is also or primarily intended for civilian use.
- Deliveries to certain countries may be blocked or delayed.
- Development data may not be freely shared with international teams or partners.
- Maintenance and software updates can fall under US regulation.
- Long-term platform strategies are dependent on geopolitical developments.
This creates a significant strategic risk, especially for products with long life cycles – such as ship propulsion, industrial platforms, or turbine controls. Changes in US foreign policy or export controls can have a direct impact on existing products and customer relationships years later.
ITAR-free electronics consequently aims to avoid regulatory dependencies as much as possible. This includes the conscious selection of non-ITAR-controlled components as well as the establishment of independent supply chains. For European companies, this means, among other things:
- higher export freedom,
- fewer regulatory restrictions,
- better control over technical data,
- reduced geopolitical dependence,
- more sovereignty in development and production,
- establish international cooperation.
Particularly in the context of critical infrastructure, maritime systems, defense-related applications, and industrial electronics, ITAR-free is therefore gaining increasing importance. Electronics are no longer just a technical decision today, but part of a company's strategic supply chain and security architecture.
ITAR & Electronics Summary
The regulation of Embedded Systems and electronics in the military environment show clearly how closely technology, law, and responsibility are intertwined. ITAR and DFARS create a clear framework for protecting security-relevant technologies, controlling sensitive information, and securing the defense supply chain. At the same time, „ITAR electronics“ is sometimes an exclusion criterion for use in Europe because supply chain dependencies become critical.
For developers and manufacturers, this means that technical decisions – from components to data exchange – are always also regulatory decisions.
At the same time, it is becoming clear that many component manufacturers are increasingly facing issues with ITAR, electronics, and dual-use regulations.positionSome completely exclude military applications, while others leave the decision and responsibility to the customers, protecting themselves through appropriate liability and usage disclaimers.
Actionable Recommendations for Electronics Developers and Manufacturers
- Consciously design freedom:Freedom in electronics design ends where export controls, manufacturer restrictions, or safety-related regulations come into play. Those who are aware of these limits early on can make targeted technical decisions without risking later restrictions.
- Anchor export control in the development process:Check during the concept planning phase whether components or technologies fall under ITAR, DFARS, or dual-use regulations, and integrate export control as a fixed part of your development processes.
- Ensure documentation and traceability:Identify and clearly label all sensitive components, technical data, and suppliers. Comprehensive documentation is a prerequisite for compliance and auditability.
- Equating regulatory and technical quality:Address legal requirements with the same care as technical aspects – design quality today also includes regulatory compliance.
- Promote responsibility and awareness:Regularly train teams on legal basics, manufacturer requirements, and liability issues. Only those who understand the legal framework can use design freedom safely and responsibly.
