1. (a)A license (DSP-61) issued by the Directorate of Defense Trade Controls is required for the temporary import and subsequent export of unclassified defense articles, unless exempted from this requirement pursuant to § 123.4. This requirement applies to:
   1. (1)Temporary imports of unclassified defense articles that are to be returned directly to the country from which they were shipped to the United States;
   2. (2)Temporary imports of unclassified defense articles in transit to a third country;
2. (b)A bond may be required as appropriate (see part 125 of this subchapter for license requirements for technical data and classified defense articles.)
3. (c)A DSP-61 license may be obtained by a U.S. importer in satisfaction of § 123.4(c)(4) of this subchapter. If a foreign exporter requires documentation for a permanent import, the U.S. importer must contact the Department of Justice's Bureau of Alcohol, Tobacco, Firearms and Explosives for the appropriate documentation. A DSP-61 will not be approved to support permanent import requirements.
