INTERNATIONAL TRADE LAW
ITAR Explained: Defense Exports and the USML
The International Traffic in Arms Regulations (ITAR) are the strictest U.S. export-control regime: they govern defense articles and defense services — things inherently military in design, purpose, or use — and they’re administered by the State Department’s Directorate of Defense Trade Controls (DDTC), not Commerce. If your product is on the U.S. Munitions List (USML), ITAR applies, you almost certainly need a license to export it, and — critically — you must register with DDTC even if you only manufacture the item and never export it. This guide explains what ITAR covers, the registration requirement, licensing, and how it differs from the EAR.
If you’re not sure whether your item is ITAR or EAR controlled, start with our overview of the three export-control regimes.
What ITAR Covers: The U.S. Munitions List
ITAR controls items and technical data on the U.S. Munitions List (22 CFR 121), organized into 21 categories spanning firearms, ammunition, launch vehicles, military aircraft and vessels, spacecraft, military electronics, and the associated technical data and defense services. “Defense article” includes not just the hardware but the technical data to design, produce, or use it — which is why sharing controlled drawings or specifications with a foreign person can itself be a regulated export. If an item was specifically designed or modified for a military application and appears on the USML, it’s ITAR-controlled, full stop.
Mandatory DDTC Registration
This is the requirement that surprises companies most. Anyone who manufactures, exports, or brokers defense articles or services must register with DDTC — and the manufacturing trigger means even a company that never exports must register if its products are on the USML. Registration:
- Is mandatory, triggered by a single qualifying activity (not by volume).
- Must be renewed annually, with a registration fee (the base tier is $2,250 per year).
- Is a precondition for applying for any ITAR license or using most ITAR exemptions.
Registration is not a license — it’s the entry ticket that lets you then seek licenses.
Licensing Defense Exports
Because ITAR items are inherently military, assume a license is required to export them. Defense-export licenses are applied for through DDTC’s electronic system (DECCS), and the agency reviews them with national-security and foreign-policy scrutiny well beyond a typical commercial export. There are limited ITAR exemptions, but each is narrow and conditional, and using one still generally requires current DDTC registration. Technical data and defense services to foreign persons — including foreign employees inside the U.S. — are licensed activities too.
ITAR vs EAR
| ITAR | EAR | |
|---|---|---|
| Covers | Defense articles/services (military) | Commercial and dual-use items |
| List | U.S. Munitions List (21 categories) | Commerce Control List (ECCNs) |
| Agency | DDTC (State) | BIS (Commerce) |
| Registration | Mandatory (even manufacturers) | None to register |
| License | Almost always required | Depends on item, destination, party, use |
If jurisdiction is unclear — common for items with both civilian and military variants — request a Commodity Jurisdiction determination from DDTC to confirm whether ITAR or the EAR applies.
Frequently Asked Questions
What does ITAR control?
ITAR controls defense articles and defense services on the U.S. Munitions List — items inherently military in design or purpose — across 21 categories, including the technical data needed to design, produce, or use them. It is administered by the State Department’s DDTC.
Do I have to register with DDTC if I don’t export?
Yes, if you manufacture USML items. DDTC registration is mandatory for manufacturers, exporters, and brokers of defense articles — and the manufacturing trigger means a company that makes USML items must register even if it never exports them.
How much does ITAR (DDTC) registration cost?
Registration must be renewed annually and the base registration tier is $2,250 per year. Registration is a precondition for applying for ITAR licenses or using most ITAR exemptions; it is separate from any license.
What is the difference between ITAR and EAR?
ITAR (State/DDTC) governs inherently military defense articles on the U.S. Munitions List and almost always requires a license, with mandatory registration. The EAR (Commerce/BIS) governs commercial and dual-use items on the Commerce Control List, where license requirements depend on the item, destination, party, and end use.
ITAR violations carry some of the most severe penalties in trade law, and the registration trap catches manufacturers who never intended to export. Reidel Law Firm advises defense-trade companies on jurisdiction, registration, and licensing on flat-fee terms. Get an export compliance memo.
