My research is exempt from export controls under the Fundamental Research Exclusion, can I ship items developed as part of that research overseas?

It depends on whether the items developed are subject to the export control laws.  Although the Fundamental Research Exemption is broad, it generally does not authorize the transfer of physical items outside the U.S. Before shipping or taking any item abroad, even if that item is the result of Fundamental Research, an export control determination needs to be done to determine if a license is required.
