                         U.S. IMPORT AND EXPORT PRICE INDEXES - APRIL 2012

U.S. import prices declined 0.5 percent in April, the U.S. Bureau of Labor Statistics reported today, 
following a 1.5 percent increase in March. The April decrease was driven by lower fuel prices which more 
than offset a small increase in nonfuel prices. The price index for overall exports rose 0.4 percent in April 
after a 0.8 percent increase the previous month. 

 
Imports
 	
All Imports: Prices for U.S. imports fell 0.5 percent in April, the first monthly decrease since a 0.4 percent 
decline in October 2011 and the largest one-month drop since the index decreased 0.6 percent in June 2011. 
Despite the April decline, import prices rose 0.5 percent over the past year, although that was the smallest 
12-month advance since the index last recorded a year-over-year decrease in October 2009.  

Fuel Imports: A 2.1 percent drop in fuel prices led the overall decline in import prices in April. The decrease 
in fuel prices followed a 4.4 percent increase in March and was the largest decline for the index since a 
similar 2.1 percent decrease in August 2011. A 1.8 percent decline in petroleum prices and a 14.1 percent 
drop in natural gas prices each contributed to the April decrease in overall fuel prices. Fuel prices also fell 
over the past 12 months as a 45.3 percent decline in natural gas prices more than offset higher petroleum 
prices that ticked up 0.1 percent from April 2011 to April 2012. The decrease in overall fuel prices was the 
first 12-month decline since the index fell 14.2 percent for the year ended in October 2009.     

All Imports Excluding Fuel: The price index for nonfuel prices ticked up 0.1 percent in April after rising 
0.5 percent the previous month. Higher prices for nonfuel industrial supplies and materials, automotive 
vehicles, consumer goods, and foods, feeds, and beverages all contributed to the increase in overall nonfuel 
prices. Capital goods prices were unchanged. Nonfuel prices rose 1.3 percent over the past 12 months.  

Table A. Percent changes

Exports
 
All Exports: U.S. export prices increased 0.4 percent in April as agricultural and nonagricultural prices each 
contributed to the advance. The April rise in overall export prices followed a 1.5 percent increase in the first 
quarter of 2012. Export prices advanced 0.7 percent for the April 2011-12 period, the smallest year-over-
year increase since the index rose 0.4 percent between November 2008 and November 2009. The 12-month 
increase in April was led by higher nonagricultural prices which more than offset declining agricultural prices 
over the past year.   

Agricultural Exports: Agricultural prices rose 2.0 percent in April after rising 2.5 percent in March. The 
April advance was led by a 7.4 percent increase in soybean prices. Despite the increases in the past two 
months, agricultural prices fell 3.1 percent over the past 12 months. That decline was driven by falling 
cotton, corn, and wheat prices between April 2011 and April 2012.       

All Exports Excluding Agriculture: The price index for nonagricultural prices advanced 0.2 percent in 
April following a 0.5 percent rise the previous month. Rising prices for nonagricultural industrial supplies 
and materials, as well as automotive vehicles, more than offset lower consumer goods prices. Overall 
nonagricultural prices increased 1.2 percent for the year ended in April.

                                          TECHNICAL NOTE


Import and Export Merchandise and Services Price Indexes -- All indexes use a modified Laspeyres 
formula and are not seasonally adjusted.  Price indexes are reweighted annually, with a two-year lag in 
the weights.  Published series use a base year of 2000=100 where possible.  More detailed index series 
and additional information may be obtained at http://www.bls.gov/mxp, or by calling (202) 691-7101.

Merchandise Goods Classification Systems -- The merchandise price indexes are published using 
three classification systems.  Items are classified by end use according to the Bureau of Economic 
Analysis Classification System, by industry according to the North American Industry Classification 
System (NAICS), and by product category according to the Harmonized System (HS).  While 
classification by end use and product category are self-explanatory, some notes are in order for 
classifying items by industry.  In the NAICS imports and exports tables, items are classified by output 
industry, not input industry.  As an example, NAICS import index 326 (plastics and rubber products 
manufacturing) include outputs such as manufactured plastic rather than inputs such as petroleum.  The 
NAICS classification structure also matches the classification system used by the PPI (Producer Price 
Index) to produce the NAICS primary products indexes.

Import Price Indexes -- Products have been classified by the Harmonized Tariff Schedule of the United 
States Annotated (TSUSA).  Import prices are based on U.S. dollar prices paid by the U.S. importer.  
The prices are generally either "free on board" (f.o.b.) foreign port or "cost, insurance, and freight" 
(c.i.f.) U.S. port transaction prices, depending on the practices of the individual industry.  The index for 
crude petroleum is calculated from data collected by the U.S. Department of Energy.  

Export Price Indexes -- Products have been classified by the Harmonized Schedule B classification 
system of the U.S. Bureau of the Census.  The prices used are generally either "free alongside ship" 
(f.a.s.) factory or "free on board" (f.o.b.) transaction prices, depending on the practices of the individual 
industry.  Prices used in the grain index, excluding rice, are obtained from the U.S. Department of 
Agriculture.

Services Price Indexes -- Starting in September 2008 the Import Air Passenger Fares Indexes represent 
changes in the average revenue per passenger received by foreign carriers from U.S. residents and are 
calculated from data obtained from an airline consulting service.  These data include tickets sold by 
travel agencies and travel websites.  Tickets sold directly by the airlines are excluded, as are frequent 
flyer tickets generally.  Starting in January 2008 the Export Air Passenger Fares Indexes represent 
changes in the average revenue per passenger received by U.S. carriers from foreign residents and are 
calculated from data collected directly from airlines. These data include frequent flyer tickets and those 
sold by consolidators. Taxes and fees are included in the Import Air Passenger Fares Index and excluded 
from the Export Air Passenger Fares Index. The Air Freight Indexes are calculated from data collected 
directly from airlines. These data exclude mail and passenger baggage. The scope of the service being 
priced is the movement of freight from airport to airport only, and does not include any ground 
transportation or port service. The Air Freight Indexes are presented using two definitions: Balance of 
Payments (which represent transactions between U.S. and foreign residents) and International (which 
represent transactions inbound to and outbound from the U.S.). Fact sheets specifying detailed 
information for each services industry are available at http://www.bls.gov/mxp under "MXP 
Publications."

Import Indexes by Locality of Origin -- Prices used in these indexes are a subset of the data collected 
for the Import Price Indexes.  Beginning with January 2002, the indexes are defined by locality of origin 
using a nomenclature based upon the North American Industry Classification System (NAICS).  
Nonmanufactured goods are defined as NAICS 11 and 21 and manufactured goods are defined as 
NAICS 31-33. 
 
Revision Policy -- To reflect the availability of late reports and corrections by respondents, monthly data 
may be revised in each of the three months after original publication.  After three months, no further data 
revisions take place.  So, for example, data released in the January release will be subject to revision in 
the releases for February, March, and April.

Uses of the Data -- The primary use of the indexes is to deflate trade statistics, notably the foreign trade 
sector of the National Income and Product Accounts constructed by the Department of Commerce.  
Other published indexes are useful for general market analysis.  For trade in international services, 
Balance of Payments indexes are used for deflating National Income and Product Accounts, while 
International indexes are more appropriate for market analysis.  Merchandise and services indexes also 
can be used to study U.S. competitiveness and to compute price elasticities, and the merchandise import 
indexes by country or region of origin are useful in terms of trade analysis.
