International Traffic in Arms Regulations (ITAR)
U.S. regulations controlling the export and import of defense articles, defense services, and related technical data — administered by the State Department's Directorate of Defense Trade Controls.
Definition
The International Traffic in Arms Regulations (ITAR) are U.S. federal regulations that control the export and temporary import of defense articles, defense services, and related technical data listed on the U.S. Munitions List (USML). Administered by the U.S. Department of State's Directorate of Defense Trade Controls (DDTC), ITAR applies to any company that manufactures, exports, or brokers defense articles or services — including many in the aerospace, defense, and advanced manufacturing sectors.
What ITAR Controls
ITAR controls items on the U.S. Munitions List (USML) — a 21-category list of articles, services, and technical data that are inherently military or that provide significant military advantage. Categories include firearms and ammunition, aircraft and related articles, military electronics, spacecraft systems, naval vessels, nuclear weapons, and more.
Critically, ITAR does not only apply to finished weapons systems. It also applies to components, parts, software, technical data (including specifications, manuals, and blueprints), and defense services (such as training, engineering, or maintenance performed for foreign persons). Technical data alone — an email with design specifications — can constitute an ITAR-controlled export.
Who Must Register Under ITAR?
Any U.S. company that manufactures, exports, or brokers defense articles or services listed on the USML is required to register with the State Department's DDTC — regardless of whether they have actually conducted an export. Registration is a prerequisite for obtaining an export license; it is not a license itself.
ITAR registration is required even for companies that only manufacture USML-controlled articles domestically, intending to sell only to U.S. government customers. The manufacturing of a USML-controlled item triggers the registration requirement.
ITAR and Restricted Party Screening
ITAR-regulated companies must screen their export counterparties — customers, end users, freight forwarders, and intermediaries — against the State Department's AECA Debarred List, which identifies parties who have been prohibited from participating in defense article exports. They must also screen against OFAC sanctions lists, which may prohibit transactions with certain foreign parties entirely.
The State Department's AECA Debarred List is included in the U.S. Consolidated Screening List, making a comprehensive CSL check the appropriate starting point for ITAR-related party screening. However, ITAR-regulated companies typically also conduct country-level assessments and end-use monitoring beyond simple list checks.
Penalties for ITAR Violations
ITAR carries some of the most severe penalties in U.S. export control law. Civil penalties can reach $1 million per violation. Criminal penalties can reach $1 million per violation and up to 20 years imprisonment. Convicted individuals and companies may also be debarred — prohibited from participating in any future defense trade.
ITAR violations also carry significant reputational and contractual consequences. Defense contractors are typically required to maintain ITAR compliance as a condition of government contracts; a violation can result in contract termination and debarment from future government contracting.
How TradeLasso Helps
TradeLasso includes the State Department's AECA Debarred List in every screening search, alongside the OFAC SDN List, BIS Entity List, and 10 other U.S. government watchlists — giving ITAR-regulated exporters a single, documented party-screening record for every transaction.
Frequently Asked Questions
What is the difference between ITAR and the EAR?
ITAR (administered by the State Department) controls defense articles, defense services, and related technical data on the U.S. Munitions List. The EAR (administered by Commerce/BIS) controls commercial and dual-use items on the Commerce Control List. If an item is on the USML, it is controlled exclusively by ITAR. If it is on the CCL, it falls under the EAR. Some items fall under neither (EAR99), while some transactions involve obligations under both regimes.
Does ITAR apply to U.S. citizens working abroad?
Yes. ITAR applies to U.S. persons wherever they are located. A U.S. citizen working in a foreign country who shares ITAR-controlled technical data with a foreign national — including a colleague — is conducting an ITAR-controlled export and must have appropriate authorization.
What is a "deemed export" under ITAR?
Under ITAR, releasing or disclosing ITAR-controlled technical data to a foreign national — including in the United States — is treated as an export to that person's home country. This means that sharing defense-related specifications, blueprints, or manuals with a foreign national employee or contractor on U.S. soil requires an ITAR license or other authorization, just as a physical export would.
Do small companies need to comply with ITAR?
Yes. ITAR compliance obligations do not have a company-size exemption. Any company that manufactures, exports, or brokers USML-controlled articles or services — regardless of size — must register with DDTC and comply with all applicable ITAR requirements. Small manufacturers who supply components to defense prime contractors are frequently subject to ITAR obligations.
