(a) Application—(1) Shipments to foreign countries. Except for aircraft bound for foreign locations referred to in paragraph (b) of this section, clearance, or permission to depart may be given to an aircraft bound for a foreign location by the CBP at the departure airport before a complete manifest or all required Electronic Export Information (EEI) have been filed, if a proper bond is filed on CBP Form 301, containing the bond conditions set forth in subpart G of part 113 of this chapter.

As provided in § 122.79(b), any required air cargo manifest or EEI filing citations, exclusions, and/or exemption legends for direct flights between the United States and Puerto Rico must be filed with the appropriate CBP officer upon arrival in Puerto Rico. If any required manifest or EEI filing citations, exclusions, and/or exemption legends are not filed with the appropriate CBP officer within one business day after arrival in Puerto Rico, a proper bond must be filed at that time on CBP Form 301, containing the bond conditions set forth in subpart G of part 113 of this chapter.
