1. When customs notification is required on
flights to Canada and Mexico and a predeparture
flight plan cannot be filed or an advise customs
message (ADCUS) cannot be included in a
predeparture flight plan, call the nearest en route
domestic or International FSS as soon as radio
communication can be established and file a VFR or
DVFR flight plan, as required, and include as the last
item the advise customs information. The station with
which such a flight plan is filed will forward it to the
appropriate FSS who will notify the customs office
responsible for the destination airport.
2. If the pilot fails to include ADCUS in the
radioed flight plan, it will be assumed that other
arrangements have been made and FAA will not
advise customs.
3. The FAA assumes no responsibility for any
delays in advising customs if the flight plan is given
too late for delivery to customs before arrival of the
aircraft. It is still the pilot's responsibility to give
timely notice even though a flight plan is given to

4. Air Commerce Regulations of the Treasury
Department's Customs Service require all private
aircraft arriving in the U.S. via:

(a) The U.S./Mexican border or the Pacific
Coast from a foreign place in the Western
Hemisphere south of 33 degrees north latitude and
between 97 degrees and 120 degrees west longitude;
(b) The Gulf of Mexico and Atlantic Coasts
from a foreign place in the Western Hemisphere south
of 30 degrees north latitude, must furnish a notice of
arrival to the Customs service at the nearest

designated airport. This notice may be furnished
directly to Customs by:
(1) Radio through the appropriate FAA
Flight Service Station.
(2) Normal FAA flight plan notification
procedures (a flight plan filed in Mexico does not
meet this requirement due to unreliable relay of data);
(3) Directly to the district Director of
Customs or other Customs officer at place of first
intended landing but must be furnished at least 1 hour
prior to crossing the U.S./Mexican border or the U.S.

(c) This notice will be valid as long as actual
arrival is within 15 minutes of the original ETA,
otherwise a new notice must be given to Customs.
Notices will be accepted up to 23 hours in advance.
Unless an exemption has been granted by Customs,
private aircraft are required to make first landing in
the U.S. at one of the following designated airports
nearest to the point of border of coastline crossing:
