If you work in defense manufacturing, aerospace, or dual-use technology, you have almost certainly encountered the acronyms ITAR and EAR. Both are U.S. export control regimes, both carry serious penalties for non-compliance, and both require companies to understand whether their products, technology, or services are regulated before exporting them. But they are administered by different agencies, cover different goods, and impose different obligations.
Here is a practical breakdown of what each regime covers, how they differ, and what compliance professionals need to know.
What Is ITAR?
ITAR stands for the International Traffic in Arms Regulations. It is administered by the Directorate of Defense Trade Controls (DDTC) within the U.S. Department of State. ITAR implements the Arms Export Control Act (AECA) and controls the export, re-export, and transfer of defense articles, defense services, and related technical data.
The list of items controlled under ITAR is called the United States Munitions List, or USML. The USML is organized into categories covering everything from firearms and ammunition to military aircraft, naval vessels, night vision equipment, satellites, and more. If your product, component, or technology appears on the USML, it is subject to ITAR — full stop.
Key characteristics of ITAR:
- Administered by: U.S. Department of State, DDTC
- Controlling list: United States Munitions List (USML)
- Scope: Defense articles, defense services, and technical data specifically designed or modified for military use
- Primary license type: State Department license or applicable exemption
- Registration requirement: Most manufacturers, exporters, and brokers of ITAR-controlled items must register with DDTC
ITAR is broadly considered the more restrictive of the two regimes. Once a product or technology is ITAR-controlled, there is very little flexibility in how it is transferred, even to close allies.
What Is EAR?
EAR stands for the Export Administration Regulations. It is administered by the Bureau of Industry and Security (BIS) within the U.S. Department of Commerce. EAR controls the export, re-export, and transfer of dual-use items — goods, software, and technology that have both commercial and potential military or proliferation applications.
The list of items controlled under EAR is called the Commerce Control List, or CCL. Items on the CCL are assigned an Export Control Classification Number (ECCN), which determines what license requirements apply based on the destination country, end user, and end use.
Key characteristics of EAR:
- Administered by: U.S. Department of Commerce, BIS
- Controlling list: Commerce Control List (CCL)
- Scope: Dual-use goods, software, and technology; also items not on the USML but still subject to U.S. jurisdiction
- Primary license type: Commerce license or license exception
- EAR99: Items subject to EAR but not listed on the CCL fall into a catch-all category called EAR99 — these items generally do not require a license for most destinations, but restrictions still apply to embargoed countries or prohibited end users
EAR tends to be more nuanced than ITAR because the license requirement depends heavily on where the item is going and who is receiving it. An item might move freely to Canada but require a license for export to a country of concern.
The Core Difference: Designed for Military vs. Dual-Use
The most important conceptual distinction between ITAR and EAR is the nature of the item itself.
ITAR focuses on items specifically designed, developed, configured, adapted, or modified for military end use. The question is whether the item belongs on the USML because of its inherent military character.
EAR focuses on items with commercial utility that also carry national security, foreign policy, or proliferation concerns. The question is whether the item has a dual-use nature that warrants regulatory oversight, even if it was not built exclusively for military purposes.
In practice, this distinction can get complicated. Some items were originally ITAR-controlled but have been "transitioned" to the CCL as part of Export Control Reform (ECR) — a multi-year effort to move less sensitive military items off the USML. This is why many defense contractors now encounter ECCNs like "600 series" entries on the CCL, which cover items formerly on the USML that are now regulated under EAR with stricter controls than typical commercial items.
Who Controls What — and Why It Matters
Getting the classification wrong has real consequences. If you treat an ITAR-controlled item as EAR-regulated, you may export without the required State Department license and face enforcement action. If you over-classify an EAR item as ITAR, you may impose unnecessary compliance burdens and restrict legitimate business activities.
The classification process matters at every stage: product design, subcontractor agreements, hiring foreign nationals, providing technical assistance, and selling to foreign governments. Both ITAR and EAR extend to deemed exports — meaning that sharing controlled technical data or technology with a foreign national on U.S. soil can trigger export control obligations just as if you physically shipped the item abroad.

Practical Steps for Compliance Teams
- Classify before you export. Determine whether your item falls on the USML, the CCL, or neither before any transfer takes place.
- Document your classification rationale. Regulators expect written records of how you reached your classification conclusion. See our security and recordkeeping guidance for more on audit trails and data retention.
- Screen your parties. Both regimes require you to avoid transactions with denied parties, debarred persons, and sanctioned entities — regardless of whether a license is otherwise required.
- Revisit classifications as products evolve. A design change can shift a product's classification. Build periodic review into your compliance program.
- Get counsel involved for edge cases. When ITAR and EAR overlap, or when you're dealing with newly transitioned 600-series items, consult qualified export counsel. See our FAQ for additional context on when professional advice is essential.
