If your company exports defense articles or shares technical data with foreign persons, you generally need a license or other approval from the State Department's Directorate of Defense Trade Controls (DDTC). But ITAR is not entirely a license-or-nothing system. The regulations include a set of exemptions — specific, narrowly defined circumstances where an export, reexport, or transfer can occur without prior DDTC approval.
Understanding which exemptions apply to your situation, and what conditions attach to each, is one of the more practical skills in day-to-day ITAR compliance. Misusing an exemption — or assuming one applies when it doesn't — carries real risk. What follows is a practical overview designed to help defense contractors think through this area more carefully.
What Is an ITAR Exemption?
An ITAR exemption is not a waiver of the regulations. It is a pre-authorized category of activity that DDTC has determined does not require a separate license application, provided specific conditions are fully met. If any condition is not met, the exemption is unavailable and a license is required.
Exemptions are found in Part 123 (for hardware exports), Part 124 (for agreements), and Part 125 (for technical data and defense services) of the International Traffic in Arms Regulations (22 CFR Parts 120–130). Before relying on any exemption, you need to confirm the item is actually subject to the ITAR — meaning it appears on the United States Munitions List (USML) — and that no other disqualifying conditions apply.
Common Exemptions Defense Contractors Should Know
Government-to-Government Transfers
One of the most frequently used exemptions covers exports made by or for an agency of the U.S. government. When a foreign government acquires U.S. defense articles through a Foreign Military Sale (FMS) or through direct procurement by a U.S. government agency, the export is often covered without a separate commercial license. However, contractors fulfilling these orders still need to pay attention: the exemption attaches to the government action, not automatically to every shipment made by a private company on the government's behalf. Review the specific conditions carefully.
Defense Services to Dual and Third-Country Nationals
The treatment of foreign nationals working alongside U.S. personnel on ITAR-controlled programs is one of the more operationally complex areas of ITAR compliance. Sharing technical data with a foreign person in the United States — or abroad — can constitute a "deemed export" or a "deemed reexport" that requires either a license or a valid exemption. There is an exemption for foreign nationals employed by U.S. persons under certain circumstances, but it comes with documentation requirements and does not extend to all nationalities or situations. Many contractors rely on Technology Control Plans (TCPs) and employment-based screenings to manage this risk, rather than assuming an exemption applies.
Intracompany and Intragovernment Transfers
ITAR includes exemptions for certain transfers of technical data between U.S. entities and their foreign subsidiaries or affiliates. These are sometimes called "intracompany" or "internal" exemptions. They can cover sharing of data within a corporate family for certain purposes, but they generally do not permit onward disclosure to third parties abroad, and they carry their own conditions around which countries are involved and what the data will be used for. Companies with overseas operations should map out data flows carefully before relying on this category.
Temporary Imports and Exports
There is an exemption framework for items temporarily exported from the United States and returned — for example, for demonstration, testing, or repair — and for items temporarily imported for the same purposes. The temporary export exemption is frequently used by defense companies attending trade shows, conducting field demonstrations, or returning hardware to foreign customers for evaluation. Key requirements typically include the intent and ability to return the item to the United States, proper documentation, and in some cases advance notice to DDTC or use of an AES filing with an appropriate designation.
Canadian Exemptions
The ITAR maintains a special exemption framework for exports to Canada, reflecting the close defense industrial relationship between the two countries. Many defense articles and technical data transfers can move between the United States and Canada without a license under this framework. However, the Canadian exemption is not unlimited. It generally does not apply to certain sensitive USML categories, classified items, items subject to congressional notification requirements, or re-exports to third countries. Contractors using the Canadian exemption should confirm eligibility item by item and category by category.
What Disqualifies an Exemption?
Several conditions will override an otherwise available exemption regardless of the category involved:
- Classified information. Classified defense articles and technical data are generally outside the scope of standard exemptions and require separate handling under specific authorities.
- Prohibited countries and persons. If the recipient country or individual is subject to an arms embargo or appears on a DDTC debarred parties list, no exemption applies.
- Specific USML categories. Some USML categories are explicitly excluded from one or more exemptions. Check the text of the relevant exemption and the applicable USML category.
- Congressional notification requirements. Certain significant defense exports require congressional notification, which cannot be bypassed by an exemption.

Documentation and Recordkeeping
Relying on an exemption does not eliminate your recordkeeping obligations. ITAR requires that records supporting exemption use be maintained for a specified period. Those records should demonstrate that you assessed the exemption conditions, confirmed eligibility, and maintained the documentation trail needed to defend your determination in the event of an audit or inquiry. For more on how ITAR Screen supports audit-ready recordkeeping, see our security and recordkeeping overview.
Classification Comes First
Before any exemption analysis can happen, you need to know whether your item is on the USML at all — and if so, under which category. Misclassification is one of the most common root causes of exemption errors. If a company incorrectly assumes an item is EAR99 or subject only to the Export Administration Regulations, it may skip ITAR analysis entirely, including the question of whether a license or exemption is needed.
You can explore USML categories in detail — including Category VIII (Aircraft) and others — to understand how specific hardware and technical data are classified before layering exemption analysis on top.
