GOODS

CENSUS BASIS

The Census basis goods data are compiled from the documents collected by the U.S.
Customs Border and Protection and reflect the movement of goods between foreign
countries and the 50 states, the District of Columbia, Puerto Rico, the U.S. Virgin
Islands, and U.S. Foreign Trade Zones.  They include government and non-government
shipments of goods, and exclude shipments between the United States and its territories
and possessions, transactions with U.S. military, diplomatic and consular installations
abroad, U.S. goods returned to the United States by its Armed Forces, personal and
household effects of travelers, and in-transit shipments.  The General Imports value
reflects the total arrival of merchandise from foreign countries that immediately
enters consumption channels, warehouses, or Foreign Trade Zones.

For imports, the value reported is the U.S. Customs Border and Protection appraised
value of merchandise;  generally, the price paid for merchandise for export to the
United States.  Import duties, freight, insurance, and other charges incurred in
bringing merchandise to the United States are excluded.

Exports are valued at the f.a.s. - free alongside ship - value of merchandise at
the U.S. port of export, based on the transaction price including inland freight,
insurance, and other charges incurred in placing the merchandise alongside the carrier
at the U.S. port of exportation.

Monthly data include actual month's transactions as well as a small number of transactions
for previous months.  Each month we revise the aggregate seasonally adjusted (current
and chain-weighted dollar) and unadjusted export, import and trade balance figures,
as well as the end-use totals for the prior month.  SITC and country detail data are
not revised monthly.  The timing adjustment shown in Exhibit 14 is the difference between
monthly data as originally reported and as recompiled. Quarterly revisions are made
to the chain-weighted dollar series. In the last month of each quarter, the current
and previous quarter are revised to incorporate the Bureau of Labor Statistics' monthly
revisions and align Census and the U.S. Bureau of Economic Analysis' quarterly data.
Annual revisions for the months are made in June to reflect corrections received
subsequent to the monthly revision. These revisions are reflected in totals, end-use,
SITC and country summary data. The monthly end-use, commodity, and country and area
data presented in this release are on a Census basis.  This refers to Exhibits 6 - 18.

U.S./CANADA DATA EXCHANGE AND SUBSTITUTION

The data for U.S. exports to Canada are derived from import data compiled by Canada.
The use of Canada's import data to produce U.S. export data requires several alignments
in order to compare the two series.

1.   Coverage -- Canadian imports are based on country of origin.  U.S. goods shipped
     from a third country are included.  U.S. exports exclude these foreign shipments.
     For March 2007, these shipments totaled $112.7 million.  U.S. export coverage 
     also excludes certain Canadian postal shipments.  For March 2007, these shipments 
     totaled $23.0 million.

     U.S. import coverage includes shipments of railcars and locomotives from Canada.
     Effective with January 2004 statistics, Canada excludes these shipments from its
     goods exports to the United States, therefore creating coverage differences between
     the two countries for these goods.

2.   Valuation -- Canadian imports are valued at the point of origin in the United States.
     However, U.S. exports are valued at the port of exit in the United States and include
     inland freight charges, making the U.S. export value slightly larger.  Canada requires
     inland freight to be reported.  Inland freight charges for March 2007 accounted for 
     2.0 percent of the value of U.S. exports to Canada.

3.   Reexports -- U.S. exports include reexports of foreign goods. Again, the aggregate
     U.S. export figure is slightly larger.  For March 2007, reexports to Canada were 
     $3,005 million.

4.   Exchange Rate -- Average monthly exchange rates are applied to convert the published
     data to U.S. currency.  For March 2007, the average exchange rate was 1.1682 
     Canadian dollars per U.S. dollar.

5.   Other -- There are other minor differences which are statistically insignificant,
     such as rounding error.

Canadian Estimates

Effective with January 2001 statistics, the current month data for exports to Canada
contain an estimate for late arrivals and corrections.  The following month, this
estimate is replaced, in the press release tables only, with the actual value of late
receipts and corrections.  This estimate improves the current month data for exports
to Canada and treats late receipts for exports to Canada in a manner more consistent
with the treatment of late receipts for exports to other countries.

Nonsampling errors

The goods data are a complete enumeration of documents collected by the U.S. Customs
Border and Protection and are not subject to sampling errors; but they are subject to
several types of nonsampling errors.  Quality assurance procedures are performed at
every stage of collection, processing and tabulation; however the data are still
subject to several types of nonsampling errors.  The most significant of these include
reporting errors, undocumented shipments, timeliness, data capture errors, and errors
in the estimation of low-valued transactions.

Reporting Errors: Reporting errors are mistakes or omissions made by importers, exporters
or their agents in their import or export declarations.  Most errors involve missing
or invalid commodity classification codes and missing or incorrect quantities or
shipping weights.  They have a negligible effect on import, export and balance of
trade statistics.  However, they can affect the detailed commodity statistics.

Undocumented Shipments: Federal regulations require importers, exporters or their
agents to report all merchandise shipments above established exemption levels.  The
U.S. Census Bureau has determined that not all required documents are filed,
particularly for exports.

Timeliness and Data Capture Errors: The U.S. Census Bureau captures import and export
information from administrative documents and through various automated collection
programs.  Documents may be lost, and data may be incorrectly keyed, coded or recorded.
Transactions may be included in a subsequent month's statistics if received late.

Low-valued Transactions: The total values of transactions valued as much as or below
$2,500 for exports and $2,000 ($250 for certain quota items) for imports are estimated
for each country, using factors based on the ratios of low-valued shipments to individual
country totals for past periods.

The U.S. Census Bureau recommends that data users incorporate this information into
their analyses, as nonsampling errors could impact the conclusion drawn from the results.
For a detailed discussion of errors affecting the goods data, see "U.S. Merchandise Trade
Statistics: A Quality Profile" available on the INTERNET at www.census.gov/foreign- trade

Adjustments for Seasonal and Working-Day Variations

Goods are initially classified under the Harmonized System (HS) which describes and
measures the characteristics of goods traded. Combining trade into approximately 140
export and 140 import end-use categories makes it possible to examine goods according
to their principal uses (See Exhibits 7 and 8).  These categories are used as the basis
for computing the seasonal and working-day adjusted data.  These adjusted data are then
summed to the six end-use aggregates for publication (Exhibit 6).  These data are
provided to the U.S. Bureau of Economic Analysis, from the U.S. Census  Bureau, for use
in the Balance of Payments and the National Income and Product Accounts.

The seasonal adjustment procedure is based on a model that estimates the monthly movements
as percentages above or below the general level of each end-use commodity series (unlike
other methods that redistribute the actual series values over the calendar year).  Because
of the extremely variable movements of the data series for aircraft, users studying data
trends may wish to analyze aircraft separately from other trade.

Adjustments for Price Change

Data adjusted for seasonal variation on a chained-dollar basis (2000 base year) are
presented in Exhibits 10 and 11.  This adjustment for price change is done using the
Fisher chain-weighted methodology.  The deflators are primarily based upon the monthly
price indexes published by the Bureau of Labor Statistics using techniques developed for
the National Income and Product Accounts by the U.S. Bureau of Economic Analysis.

SITC Data

Goods data appearing in Exhibit 15 are classified in terms of the Standard International
Trade Classification (SITC) Revision 3.  Agricultural goods consist of non-marine food
products and other products of agriculture which have not passed through complex
processes of manufacture, such as raw hides and skins, fats and oils, and wine.  A few
goods such as essential oils, starches, casein, and albumin, considered to be agricultural
by the U.S. Department of Agriculture, have been excluded from agricultural goods and
are included in manufactured goods where they are classified in the SITC.

Manufactured goods conform to the SITC sections that include chemicals and related products;
manufactured goods classified chiefly by material; machinery and transport equipment;
miscellaneous manufactured articles; and goods and transactions not classified elsewhere.

Reexports are foreign merchandise entering the country as imports, and  at the time of
exportation are in substantially the same condition as when imported.  Reexports,
included in overall export totals, appear as separate line items in Exhibit 15.

Advanced Technology Products (ATP)

About 500 of some 22,000 commodity classification codes used in reporting U.S. merchandise
trade are identified as "advanced technology" codes and they meet the following criteria:

1.   The code contains products whose technology is from a recognized high technology field
     (e.g., biotechnology).

2.   These products represent leading edge technology in that field.

3.   Such products constitute a significant part of all items covered in the selected
     classification code.

The aggregation of the goods results in a measure of advanced technology trade which
appears in Exhibit 16 and 16A.  This product and commodity-based measure of advanced
technology differs from broader NAICS industry-based measures which include all goods
produced by a particular industry group, regardless of the level of technology embodied
in the goods.

BALANCE OF PAYMENTS (BOP) BASIS

Goods on a Census basis are adjusted by the U.S. Bureau of Economic Analysis to goods
on a BOP basis to bring the data in line with the concepts and definitions used to prepare
the international and national accounts.  Broadly, the adjustments include changes in
ownership that occur without goods passing into or out of the customs territory of the
United States.  These adjustments are necessary to supplement coverage of the Census basis
data, to eliminate duplication of transactions recorded elsewhere in the international
accounts, and to value transactions according to a standard definition.

The export adjustments include:

     U.S. military sales contracts - This deduction of U.S. military sales contracts is
     made because the U.S. Census Bureau has included these contracts in the goods data,
     but BEA includes them in the service category "Transfers Under U.S. Military Sales
     Contracts."  BEA's source material for these contracts is more comprehensive, but
     has no distinction between goods and services.

     Private gift parcels - This addition is made for parcels mailed to foreigners by
     individuals through the U.S. Postal Service. (Only commercial shipments are covered
     in Census goods exports.)

     Gold exports, nonmonetary - This addition is made for gold that is purchased by
     foreign official agencies from private dealers in the United States and held at
     the Federal Reserve Bank of New York.  The Census data only include gold that
     leaves the customs territory.

     Some smaller adjustments are also made to exports:
     Deductions for repairs of goods, developed motion picture film, and military grant-aid.
     Additions for sales of fish in U.S. territorial waters, exports of electricity to
     Mexico, and vessels and oil rigs that change ownership for which no export document
     is filed.

The import adjustments include:

     Inland freight in Canada - An addition is made for inland freight in Canada.  Imports
     of goods from all countries are valued at the foreign port of export, including inland
     freight charges ("customs value").  In the case of Canada, this should be the cost of
     the goods at the U.S. border.  However, the customs value for imports for certain
     Canadian goods is the point of origin in Canada.  The BEA makes an addition for the
     inland freight charges of transporting these Canadian goods to the U.S. border to
     make the value comparable to the customs value as reported by all other countries.
     Insurance and freight charges for transporting goods to the United States from all
     other countries to the U.S. border are included in services by the BEA.  (The same
     procedure is used for Mexico as an Other Adjustment, but is much smaller.)

     Gold imports, nonmonetary - This addition is made for gold sold by foreign official
     agencies to private purchasers out of stock held at the Federal Reserve Bank of New
     York.  The Census data only include gold that enters the customs territory.

     Imports by U.S. military agencies - This deduction of U.S. military sales contracts
     is made because the U.S. Census Bureau has included these contracts in the goods
     data, but BEA includes them in the service category "Direct Defense Expenditures."
     BEA's source material is more comprehensive, but has no distinction between
     goods and services.

     Some smaller adjustments are also made to imports:
     Deductions for repairs of goods and developed  motion picture film.  Additions
     for imported electricity from Mexico, conversion of vessels for commercial use,
     repairs to U.S. vessels abroad, and valuation of prepackaged software imports at
     market value.

SERVICES

The statistics are estimates of services transactions between foreign countries and the
50 states, the District of Columbia, Puerto Rico, the U.S. Virgin Islands, and other
U.S. territories and possessions.  Transactions with U.S. military, diplomatic, and
consular installations abroad are excluded because they are considered to be part of
the U.S. economy.

Services are shown in seven broad categories.  Types of services for imports and exports
are the same for six of the seven categories.  For the seventh, exports is "Transfers Under
U.S. Military Sales Contracts" while for imports the category is "Direct Defense Expenditures."
The following is a brief description of the types of services included in each category:

     Travel - Purchases of services and goods by U.S. travelers abroad and by foreign
     visitors to the United States.  A traveler is defined as a person who stays for
     a period of less than 1 year in a country of which the person is not a resident.
     Includes expenditures for food, lodging, recreation, gifts, and other items
     incidental to a foreign visit.

     Passenger Fares - Fares paid by residents of one country to residents of other
     countries.  Receipts consist of fares received by U.S. carriers from foreign
     residents for travel between the United States and foreign countries and between
     two foreign points.  Payments consist of fares paid by U.S. residents to foreign
     carriers for travel between the United States and foreign countries.

     Other Transportation - Charges for the transportation of goods by ocean, air,
     waterway, pipeline, and rail carriers to and from the United States.  Includes
     freight charges, operating expenses that transportation companies incur in foreign
     ports, and payments for vessel charter and aircraft rentals with crew.

     Royalties and License Fees - Transactions with foreign residents involving intangible
     assets and proprietary rights, such as the use of patents, techniques, processes,
     formulas, designs, know-how, trademarks, copyrights, franchises, and manufacturing
     rights.  The term "royalties" generally refers to payments for the utilization of
     copyrights or trademarks, and the term "license fees" generally refers to payments
     for the use of patents or industrial processes.

     Other Private Services - Transactions with affiliated foreigners, for which no
     identification by type is available, and transactions with unaffiliated foreigners.
     (The term "affiliated" refers to a direct investment relationship, which exists when
     a U.S. person has ownership or control, directly or indirectly, of 10 percent or
     more of a foreign business enterprise's voting securities or the equivalent, or
     when a foreign person has a similar interest in a U.S. enterprise.)  Transactions
     with unaffiliated foreigners consist of education services; financial services
     (includes commissions and other transactions fees associated with the purchase and
     sale of securities and noninterest income of banks, and excludes investment income);
     insurance services; telecommunications services (includes transmission services
     and value-added services); and business, professional, and technical services.
     Included in the last group are advertising services; computer and data processing
     services; database and other information services; research, development, and
     testing services; management, consulting, and public relations services; legal
     services; construction, engineering, architectural, and mining services; industrial
     engineering services; installation, maintenance, and repair of equipment; and other
     services, including medical services and film and tape rentals.

     Transfers Under U.S. Military Sales Contracts (Exports only) - Exports of goods and
     services in which U.S. Government military agencies participate.  Includes both
     goods, such as equipment, and services, such as repair services and training,
     that cannot be separately identified.

     Direct Defense Expenditures (Imports only) - Expenditures incurred by U.S. military
     agencies abroad, including expenditures by U.S. personnel, payments of wages to
     foreign residents, construction expenditures, payments for foreign contractual
     services, and procurement of foreign goods.  Includes both goods and services
     that cannot be separately identified.

     U.S. Government Miscellaneous Services - Transactions of U.S. Government nonmilitary
     agencies with foreign residents.  Most of these transactions involve the provision
     of services to, or purchases of services from, foreigners; transfers of some goods
     are also included.

Services estimates are based on quarterly, annual, and benchmark surveys and partial
information generated from monthly reports.  Service transactions are estimated at
market prices.  Estimates are seasonally adjusted when statistically significant seasonal
patterns are present.  No country or area detail is available due to the lack of adequate
source data upon which to base estimates.

The revision policy is as follows:  Each month, a preliminary estimate for the current
month and a revised estimate for the immediately preceding month are released.  After
a revised month is released, no further changes are made to that month until more complete
source data become available in March, June, September, and December.  The releases in
March, June, September, and December contain revised data for the previous six months.
The release in March also contains revisions for all months of the previous year in order
to align the seasonally adjusted monthly data with annual totals.  The release in June
contains annual revisions, which reflect updated source data and changes in estimating
methodologies.

Quarterly and annual estimates of services are included as part of the U.S. international
transactions accounts, published in the April, July, October, and January issues of the
Survey of Current Business.  The next release of the U.S. international transactions
accounts is scheduled for June 15, 2007.  The Survey is available from the
Superintendent of Documents, U.S. Government Printing Office, Washington, D.C.
20402.
