Why Are Some Drawings Marked ITAR, EAR, or CUI?
If you’ve worked with aerospace or defense drawings, you’ve likely seen markings such as ITAR, EAR, EAR99, CUI, or a Distribution Statement prominently displayed in the title block. At first glance, these markings can seem interchangeable—but they serve different purposes under different U.S. regulations. Understanding what these markings mean helps engineers, buyers, suppliers, and program managers handle technical information appropriately and comply with customer and regulatory requirements.
Why Are Drawings Marked?
Engineering drawings often contain technical information that supports the manufacture, inspection, or integration of a product. Depending on the product and the information contained within the drawing, there may be legal or contractual requirements governing:
- Who may access the drawing
- How it may be shared
- Whether it may be exported
- How it should be stored
- Whether additional authorization is required before release
Drawing markings communicates those handling requirements to everyone who receives the document.
ITAR Markings
An ITAR marking generally indicates that the drawing contains technical data related to a defense article or defense service that is subject to the International Traffic in Arms Regulations (ITAR). Typical ITAR warning statements instruct recipients that:
- The information is controlled under U.S. export laws.
- Disclosure to foreign persons may be restricted.
- Export or retransfer may require U.S. Government authorization.
An ITAR marking is tied to the technical data on the drawing, not simply the fact that the product is manufactured in the United States.
EAR Markings
A drawing marked EAR indicates that the technical information is subject to the Export Administration Regulations (EAR). Unlike ITAR, the EAR governs a wide range of commercial, industrial, and dual-use technologies. An EAR marking may identify:
- An Export Control Classification Number (ECCN), or
- An EAR99 classification, when applicable.
While EAR-controlled information is often less restrictive than ITAR-controlled technical data, it is still subject to U.S. export regulations and may require authorization depending on the destination, end user, or end use.
What About EAR99?
Some companies include EAR99 directly on drawings. EAR99 means the technical information is subject to the EAR but is not specifically described by an Export Control Classification Number (ECCN) on the Commerce Control List. Although EAR99 generally allows exports to many destinations without a license, restrictions may still apply for sanctioned countries, restricted parties, or prohibited end uses.
CUI Markings
Controlled Unclassified Information (CUI) is different from ITAR and EAR. CUI is not an export classification. Instead, it is a U.S. Government information handling designation established to protect sensitive but unclassified information. Engineering drawings may be marked as CUI when they contain information requiring safeguarding under federal law, regulation, or government-wide policy.
- Common examples include:
- Controlled Technical Information (CTI)
- Covered Defense Information (CDI)
- Engineering drawings supporting DoD contracts
- Technical manuals
- Manufacturing instructions
- Test reports
CUI markings tell recipients how the information must be protected, regardless of whether it is also subject to export controls.
Distribution Statements
Many Department of Defense drawings also include a Distribution Statement (A-F). These statements identify who is authorized to receive the document. For example:
- Distribution Statement A – Approved for public release; distribution is unlimited.
- Distribution Statement D – Distribution authorized only to the U.S. Department of Defense and U.S. DoD contractors for specified reasons.
- Distribution Statement F – Further dissemination only as directed by the controlling DoD office or higher authority.
A Distribution Statement is not an export classification. It is a dissemination control applied to Department of Defense technical documents.
Can a Drawing Have More Than One Marking? Yes. In fact, many defense drawings contain multiple markings because each serves a different purpose. For example, a single drawing may include:
- A CUI banner marking
- An ITAR or EAR export control warning
- A Distribution Statement
- A proprietary notice
- A copyright notice
These markings work together to communicate different legal, contractual, and handling requirements.
Myth: If a drawing says CUI, it must be ITAR.
Reality: No. CUI and ITAR address different requirements. A drawing may be CUI without being ITAR-controlled, and an ITAR-controlled drawing may or may not also be designated as CUI, depending on the circumstances.
Myth: EAR99 means the drawing is public.
Reality: No. EAR99 is an export classification. A drawing containing EAR99 technical information may still be proprietary, confidential, or contractually restricted from public release.
Myth: A Distribution Statement is the same as export control.
Reality: No. Distribution Statements control the dissemination of certain Department of Defense documents, while ITAR and EAR regulate the export of controlled technical data and items.
Myth: Every military drawing is ITAR.
Reality: Not necessarily. Some military-related drawings are subject to ITAR, others are controlled under the EAR, and some may primarily require CUI handling or Distribution Statement restrictions. The applicable markings depend on the technical data and the governing regulations or contract requirements.
How SV Microwave Handles Controlled Technical Information
SV Microwave reviews customer requirements, applicable U.S. regulations, and contractual obligations to determine the appropriate handling of technical information.
Depending on the product and customer requirements, engineering documentation may include export control notices, CUI markings, Distribution Statements, proprietary notices, or other required markings to support compliant handling throughout the product lifecycle.
Quick Reference
Marking | Purpose | Controls |
ITAR | Identifies export-controlled defense technical data | Export of defense articles and technical data |
EAR / ECCN | Identifies export-controlled commercial or dual-use technical data | Export of commercial and dual-use items |
EAR99 | Indicates the information is subject to the EAR, but no specific ECCN applies | Export of many commercial items |
CUI | Identifies sensitive unclassified government information requiring safeguarding | Information handling and protection |
Distribution Statement | Defines who may receive certain DoD technical documents | Dissemination of DoD technical information |
Proprietary Notice | Protects company-owned confidential information | Contractual and intellectual property rights |
Drawing markings are more than labels, they communicate how technical information must be handled, shared, protected, and, when applicable, exported. Understanding the differences between ITAR, EAR, EAR99, CUI, and Distribution Statements helps organizations protect sensitive information, comply with customer requirements, and reduce the risk of improper disclosure.
