In making shipment under an individual license, the sender must mark the wrapper “STATE DEPARTMENT EXPORT LICENSE NO. _______________.” Enter the amount being shipped on the back of the license, if only a portion of the amount authorized is mailed.
When a sender presents a State Department license, compare the description of the article indicated on the license with the description of the contents shown on the customs declaration (see 123), or stated orally by the sender in the case of technical data mailed as printed matter (see 541.21). If no discrepancy is noted, and the contents of the package are mailable and are not prohibited by the country of destination, accept the package for mailing.
If the mailing represents the entire amount authorized by the license, retrieve the license from the sender, mark it Completed, apply a legible postmark, and forward it to:
OFFICE OF MUNITIONS CONTROL
US DEPARTMENT OF STATE
2201 C ST NW
WASHINGTON DC 20522–0602
If only a portion of the amount authorized is mailed, the sender must enter on the back of the license the amount being shipped and present it at the Post Office facility, where it will be postmarked and returned to the sender.
