U.S. AIRBORNE EXPORTS

AND GENERAL IMPORTS

DECEMBER 1974


Shipping Weight and Value

Customs District and Contin&t


This report presents statistics on L.S. exports and
imports by air in U.S. Customs district by continent
arrangement. Data have been compiled from Shipper's
Export Declarations fCommerce Form "525-Vi and
import entries during the regular processing of statis-
tical data on foreign trade shipments. The Customs
districts shown in this report are those having combined
exports and imports b%' air valued at $1.5 million or more
during the preceding calendar year. A complete list of
Customs districts and ports is presented in Schedule D,
Classification of U.S. Customs Districts and Port- for
U.S. Foreign Trade Statistics, Janujry 1, lc-'4 edition,
as amended.

Exports
These statistics represent exports of domestic and
foreign merchandise combined and include government
and nongovernment shipments of merchandise b, air
from the United States to foreign countries. The
statistics, therefore, include Department oi Defense
Military Assistance Program--Crantr-Aid shipments,
shipments for economic assistance under the Foreign
Assistance Act, and shipments of agricultural commod-
tries under P.I 480OThe Agricultural TradeDevelopment
and Assistance Act of 1954, asamendedi and related laws.
Shipments to LI.S. Armed Forces anddiplomatic missions
abroad for their own use are not included in the export
statistics. U.S. trade with Puerto Rico and U.S.
possessions and irade between U.S. possessions are not
included in this report, but exports from PuL rio IPico to
foreign countries are included as a part of the U.S.
export statistics. Merchandise shipped through the
United States in transit from one foreign country to
another, when documented as such with U.S. Customs,
is excluded. (Foreign merchandise that has entered the
United States asan import and is subsequently reexported
is not treated as in-transit merchandise, and is included
in this report.p The figures in this report exclude ex-
ports of household and personal effects, shipments by
mail and parcel post, and shipments of airplanes under
their own power.


The value reported in the e rMlFF/ s tjne rally
is equi.alent to a I a.s. free along l'flP' I alue- at tnh
L.'. port of export, based on the transaction price:, in-
cluding inland freight, insurance, and other charges
incurred in placing the merchandise alongside the
carrier at the U.S. port of exportation.


For security reasons, certain commodities aredesig-
nated as Special Category commodities, for which
e.curity regulations place restrictions upon the export
information that may be released. The data shown in
this report for individual i-uustoms districts and conti-
nents exclude exports of Special Category commodities,
but overall shipping eight and value total' for special
Category commodities are shown. 3. list of special
Categor, commodities may be obtained from th: Bureau
of the Census.


The statistics on exports of domestic ind foreign
merchandise to countries other than Canada reflect fully
compiled data for shipments .alued $4uO and over
combined with estimated data for shipments valued
$251--$419, based on a 50-percent probability sample
01 -uch shipments. For exports to Canada the statistics
reflect fully compiled data for shipments valuedd $2,=.i0
and over combined with estimated data for shipments
valued $251-$1.99, based on j !0-percent probability
sample of such shipments. Shipping weight and value
data are also estimated for shipmerrs valued under $251.
These estimates are not included in the data shown for
indi\ iduai Cu;tom- districts.


Sin.-. the export figurL. shown include estimates
based on a sample ol low-valued shipments, they are
subject to some degree of sampling variability. The
table on the following page provides a rough guide to
the general level of sampling variability of value totals,
on a 2 chances out of 3 basis. Usually, the higher value
figure e will have the lower percent sampling errors.


Inquiries concerning these figures should be addressed to the Chief, Foreign Trade Division, Bureau of the
Census, Washington, D.C. 20233. Tel: Area Code 301, 763-5140.

Imports

These statistics represent general imports, whichare
a combination of imports for immediate consumption and
entries into bonded warehouses. The statistics include
government as well as nongovernment shipments of


Value totals for
"Total" and "North
America" of:


merchandise by air from foreign countries to the United
States. However, American goods returned by the U.S.
Armed Forces for their own use are excluded. L.S. trade
with Puerto Rico and with L'.'. possessions and trade
between U.S. possessions are not included in this report,
but imports into Puerto Ri.co from foreign countries are
considered to beU.S, importsandare included. Merchan-
dise shipped through the United States intransit from one
foreign country to another, when documented as such
through U.S. Customs. is not reported as imports and is
excluded from the data shown in this report. iForeign
merchandise that has eni.red th%- United States as an
import and is subsequ, ntly re:xportcd is not treated as
in-transit merchandise and is included in this report.
Imports of household and personal effects, imports by
mail and parcel post,and import- of airplanLsunder their
own power are not included.




The Customs value shown in this report represents
the value of imports as appraised by the U.S. Customs
Service in accordance with the legal requirements of
Sections 402 and 402a of the Tariff Act of 1Q30, as
amended. It may be bast-d on the foreign market
value, export value, constructed %alue, \merican selling
price, etc. It generally represents a value in the foreign
country, and therefore excludes Li 5. import duties,
freight, insurance, and other charges incurred in bringing
the merchandise to the United States. This valuation is
prmaril,, used for collection of import duties .and
frequently does not reflect the actual transaction value.



The statistics shown for individual customss districts
represent fully compiled data for shipments valued $251
and over. Data for shipments valued under $251, re-
ported on formal and informal entries informal entries
generally contain items % valued under 5251'), are estimated
from a 1-percent sample for 14"-l. Separate shipping
weight and value estimate- for shipments valued under
$251 are shown. The shipping weight data are estimated
from the values on the basis of constants that have been
derived from an observation of thevalue-weight relation-
ships in past periods.



Since the statistics showing total value of imports by
all carriers include sample estimates, :hey are subject
to sampling variability. In general, the higher value
figures will have the lower percent sampling errors.
Value totals of $500,000 and over will generally have a
sampling variability of less than 3 percent; value totals
of under $500,000 will generally have a sampling
variability of less than 5.50.000.
