In general, the majority of exchanges between researchers off-campus can go forward without the requirement of an export license where the purpose of the meeting is to present research findings that have been published. However, this is only the case if they do not provide detailed information regarding defense articles found on the Munitions List, and international conferences are limited to published research which is covered by the "publicly available/public domain" exclusion provided by the regulations and no export license is needed when these discussions take place during participation in these conferences.
The U.S. Export Regulations (ITAR) only permits unlicensed export of technical information which falls within the meaning of the first categories above and is NOT ITAR-controlled.
However, technical information which is likely to be ITAR-controlled, and thus require an export license before sharing with a foreign national or foreign entity, includes detailed information about design, manufacture and test.
a. General description of defense article systems
b. Basic marketing information on function or purpose
c. Information regarding general scientific, mathematics or engineering principles commonly taught in schools, and
