(b) Other approval means a document, other than a license, issued by the Deputy Assistant Secretary of State for Defense Trade Controls, or authorized designee, that approves an activity regulated by this subchapter (e.g., approvals for brokering activities or retransfer authorizations), or the use of an exemption to the license requirements as described in this subchapter.
