ITAR vs. EAR: When PCB Fabrication Can Move Outside the U.S.

Estimated reading time: 3 minutes

The difference between ITAR and EAR is often reduced to a simple rule of thumb: ITAR programs must stay in the U.S. (exceptions apply), while EAR programs can be built anywhere. In practice, that distinction is incomplete and often leads to sourcing decisions that introduce compliance risk rather than reducing it.

Whether a PCB can be fabricated outside the United States depends not just on whether it is ITAR- or EAR-controlled, but on how the program is classified, what data is involved, who can access it, and how fabrication is executed across locations. Understanding that difference is critical for procurement, supplier quality, and engineering teams making supplier decisions.

Why ITAR and EAR Are Commonly Misunderstood
ITAR and EAR are both export control frameworks, but they regulate different types of programs and data in different ways. ITAR focuses on defense articles and defense services, with strict controls over who can access technical data, where work can be performed, and how information is shared.

For PCB fabrication, ITAR programs are generally restricted to U.S. persons and U.S. facilities, except where approved ITAR Technical Assistance Agreements authorize the transfer of controlled technical data for offshore manufacturing.

EAR, on the other hand, governs dual-use and commercial items, including many aerospace and electronics programs. EAR introduces more flexibility, but that flexibility is frequently misapplied in sourcing decisions.

What Actually Changes Under EAR
Under EAR, certain programs may be eligible for fabrication outside the United States, depending on the Export Control Classification Number (ECCN), the nature of the technical data, the end use and end user, the countries involved, or how controlled technology is handled during fabrication. This is where opportunities open up, and where mistakes are often made.

For EAR-controlled programs, offshore PCB fabrication can be compliant if the program is structured correctly and the supplier has the right controls in place.

What Still Restricts Offshore Fabrication Under EAR
Even when a program falls under EAR, there are still meaningful limits. Teams often run into issues when they assume EAR means drawings can be freely shared, CAM data can move without restriction, any offshore facility is acceptable, or supplier controls matter less.

In reality, EAR programs can still be restricted by:

• Controlled technical data embedded in fabrication files
• Access by non-authorized personnel
• Uncontrolled data transfer between sites
• Insufficient traceability or oversight

These issues often surface late, during audits, customer reviews, or program transfers, long after the sourcing decision has been made.

Where Teams Get Caught
The most common problems do not come from intentional violations. They come from assumptions. Examples include:

• A program assumed to be “commercial” that still contained controlled technology
• An offshore build approved without fully understanding data access implications
• Supplier registration being treated as a substitute for process control
• Compliance reviewed only after fabrication had already begun

By the time these issues are identified, the cost of correction is high.

What This Means for PCB Fabricator Selection
For EAR-controlled programs, supplier selection hinges on whether the fabricator understands how export control shapes fabrication operations, not simply on capability or cost.

That includes how design data is handled and segmented, access is controlled within and between facilities, traceability is maintained across locations, and compliance is preserved without disrupting execution. This is where experience matters.

How SOMACIS Approaches ITAR and EAR Programs
At SOMACIS, export control is built into day-to-day fabrication operations and supplier workflows. For ITAR programs, fabrication is typically restricted to U.S. facilities under controlled access, unless the fabricator holds approved ITAR Technical Assistance Agreements (TAAs) that authorize offshore manufacturing. SOMACIS holds such approved TAAs, which permit build-to-print PCB fabrication at specific facilities outside the United States under defined controls.

For EAR-controlled programs, fabrication can be executed outside the United States when classification and program structure allow it. In those cases, compliance is maintained through controlled data handling and access, clear separation of ITAR and EAR workflows, disciplined CAM and process execution, and conservative interpretation when classification or data sensitivity is unclear.

This allows customers to take advantage of global manufacturing capability without introducing export compliance risk.

The Takeaway
ITAR and EAR define not only where a board may be fabricated, but also how the program must be managed throughout its lifecycle. EAR can allow PCB fabrication outside the U.S., but only when classification, data handling, and supplier controls are aligned. Treating EAR as “unrestricted” often creates the very risk teams are trying to avoid.

Understanding the difference and working with fabricators who do is essential for compliant and predictable execution.
