Producer Price Indexes — April 2006 

The Producer Price Index for Finished Goods advanced 0.9 percent in April, seasonally adjusted, the 

Bureau of Labor Statistics of the U.S. Department of Labor reported today. This gain followed a 0.5-percent 

rise in March and a 1.4-percent decline in February. The index for finished goods other than foods and energy 

rose 0.1 percent, the same rate of increase as in the previous month. At the earlier stages of processing, prices 

for intermediate goods moved up 0.9 percent in April, after edging down 0.1 percent in the prior month, while 

the crude goods index increased 1.2 percent, following a 2.7-percent decrease in March. (See table A.)

Among finished goods, prices for energy goods advanced 4.0 percent in April, after rising 1.8 percent in 

the preceding month. The index for capital equipment climbed 0.2 percent, following a 0.1-percent gain in the 

previous month. Conversely, price increases for finished consumer foods slowed from 0.5 percent in March to 

0.1 percent in April. The index for finished consumer goods excluding foods and energy inched up 0.1 percent, 

compared with a 0.2-percent rise a month earlier. 

Before seasonal adjustment, the Producer Price Index for Finished Goods advanced 1.0 percent in April 

to 160.6 (1982 = 100). From April 2005 to April 2006, prices for finished goods rose 4.0 percent. Over the 

same period, the finished energy goods index increased 18.0 percent, prices for finished goods other than foods 

and energy moved up 1.5 percent, and the finished consumer foods index fell 1.3 percent. For the 12 months 

ended April 2006, prices for intermediate goods rose 7.3 percent, while the crude goods index climbed 3.4 

percent. 

Finished goods 

 Prices for finished energy goods increased 4.0 percent in April, following a 1.8-percent gain in the prior 

month. The home heating oil index jumped 13.7 percent, after falling 3.6 percent in the preceding month. 

Prices for liquefied petroleum gas, residential electric power, and diesel fuel also turned up in April, while the 

indexes for gasoline and kerosene increased at quicker rates than they had in March. By contrast, residential 

natural gas prices decreased 3.0 percent in April, compared with a 0.5-percent decline in the previous month.

trailers, industrial material handling equipment, and integrating and measuring instruments more than offset 

falling prices for passenger cars, electronic computers, construction machinery and equipment, and heavy motor 

trucks. 

 The finished consumer foods index inched up 0.1 percent in April, subsequent to a 0.5-percent gain in 

the prior month. Prices for eggs for fresh use increased 2.4 percent, after surging 29.2 percent in March. The 

index for finfish and shellfish also rose less than it had in the previous month, while pork prices turned down in 

April. The indexes for beef and veal and for processed young chickens decreased at quicker rates than they had 

a month earlier. Alternatively, prices for fresh and dry vegetables jumped 18.1 percent in April, compared with 

a 3.7-percent increase in the preceding month. The indexes for fresh fruits and melons and for processed fruits 

and vegetables also rose more than they had in March, while prices for dairy products fell less than in the prior 

month. 

The index for finished consumer goods excluding foods and energy went up 0.1 percent in April, 

following a 0.2-percent increase in March. In April, rising prices for alcoholic beverages, mobile homes, 

household furniture, book publishing, and sporting and athletic goods slightly outweighed falling prices for 

passenger cars; periodical circulation; women’s, girls’, and infants’ apparel; and sanitary paper products.

percent advance in the previous month. Leading this acceleration, prices for primary nonferrous metals rose 5.9 

percent, after a 0.5-percent gain in March. The indexes for copper and brass mill shapes, cold rolled steel sheet 

and strip, and aluminum mill shapes also increased at faster rates in April than they had a month earlier. Prices 

for titanium mill shapes and hardwood lumber turned up, and the index for hot rolled steel bars, plates, and 

structural shapes fell less than in March. By contrast, the index for semifinished steel mill products declined 4.8 

percent in April, following a 1.8-percent increase in the prior month. Prices for prepared paint and secondary 

aluminum also turned down, after climbing in March.

faster rates than they had in the prior month, while prices for dry, condensed, and evaporated milk products fell 

less than in March. 

 The index for materials and components for construction advanced 0.4 percent, the same rate of increase 

as in March. In April, rising prices for nonferrous wire and cable, concrete products, paving mixtures and 

blocks, fabricated structural metal products, steel mill products, and building paper and board outweighed 

declining prices for plastic construction products, softwood lumber, and treated wood.

Net output price indexes for mining, manufacturing, and services industries

Mining. The Producer Price Index for the Net Output of Total Mining Industries rose 2.3 percent in April, 

following a 3.0-percent decline in March. (Net output price indexes are not seasonally adjusted.) Prices 

received by the crude oil and natural gas extraction industry moved up 3.7 percent, after falling 4.8 percent in 

the previous month. The industry indexes for gold ore mining and bituminous coal underground mining also 

turned up in April. Prices received by the natural gas liquid extraction industry decreased less than they had in 

the prior month, while the industry indexes for oil and gas well drilling and for bituminous coal and lignite

Manufacturing. The Producer Price Index for the Net Output of Total Manufacturing Industries increased 1.4 

percent in April, following a 0.9-percent gain in March. The majority of this acceleration can be attributed to 

prices received by manufacturers of petroleum and coal products, which increased 12.0 percent subsequent to a 

7.9-percent rise in the previous month. The industry group indexes for electrical equipment and appliances, 

primary metals, and fabricated metal products also increased more than they had in March, while the prices paid

related support activities industry group turned down, after rising a month earlier. In April, the Producer Price 

Index for Total Manufacturing Industries was 157.1 (December 1984 = 100), 5.0 percent above its year-ago 

level. 

Services. Among services industries in April, prices received by commercial bankers advanced 12.5 percent, 

after declining 8.9 percent in March. The industry indexes for investment banking and security dealing, savings 

institutions, portfolio management, and lessors of nonresidential buildings (excluding miniwarehouses) also

Technical Note 

Brief Explanation of Producer Prices Indexes 

The Producer Price Index (PPI) of the Bureau of Labor Statistics (BLS) is a family of indexes that measure the average 

change over time in the prices received by domestic producers of goods and services. PPIs measure price change from the perspective 

of the seller. This contrasts with other measures, such as the Consumer Price Index (CPI). CPIs measure price change from the

purchaser’s perspective. Sellers’ and purchasers’ prices can differ due to government subsidies, sales and excise taxes, and 

distribution costs. 

 More than 8,000 PPIs for individual products and groups of products are released each month. PPIs are available for the 

products of virtually every industry in the mining and manufacturing sectors of the U.S. economy. New PPIs are gradually being

introduced for the products of industries in the trade, finance, and services sectors of the economy. 

More than 100,000 price quotations per month are organized into three sets of PPIs: (1) Stage-of-processing indexes; (2) 

commodity indexes; and (3) indexes for the net output of industries and their products. The stage-of-processing structure organizes 

products by class of buyer and degree of fabrication. The commodity structure organizes products by similarity of end use or material 

composition. The entire output of various industries is sampled to derive price indexes for the net output of industries and their 

products. 

Stage-of-Processing Indexes 

Within the stage-of-processing system, finished goods are commodities that will not undergo further processing and are ready 

for sale to the final-demand user, either an individual consumer or business firm. Consumer foods include unprocessed foods such as 

eggs and fresh vegetables, as well as processed foods such as bakery products and meats. Other finished consumer goods include

durable goods such as automobiles, household furniture, and appliances, as well as nondurable goods such as apparel and home 

heating oil. Capital equipment includes producer durable goods such as heavy motor trucks, tractors, and machine tools. 

 The stage-of-processing category for intermediate materials, supplies, and components consists partly of commodities that 

have been processed but require further processing. Examples of such semifinished goods include flour, cotton yarn, steel mill

products, and lumber. The intermediate goods category also encompasses nondurable, physically complete items purchased by 

business firms as inputs for their operations. Examples include diesel fuel, belts and belting, paper boxes, and fertilizers. 

Crude materials for further processing are products entering the market for the first time that have not been manufactured or 

fabricated and that are not sold directly to consumers. Crude foodstuffs and feedstuffs include items such as grains and livestock. 

Examples of crude nonfood materials include raw cotton, crude petroleum, coal, hides and skins, and iron and steel scrap. 

Commodity Indexes 

The commodity classification structure of the PPI organizes products by similarity of end use or material composition, 

disregarding industry of origin. Fifteen major commodity groupings (2-digit commodity codes) make up the All Commodities Index. 

Each major commodity grouping includes (in descending order of aggregation) subgroups (3-digit), product classes (4-digit), 

subproduct classes (6-digit), and individual items (8-digit). Nearly all 8-digit commodities under the traditional commodity coding 

system are now derived from corresponding industry-classified product indexes. In such instances, movements in the traditional

commodity price indexes and corresponding percent changes will be virtually identical to their industry-based counterparts, even if 

their index levels differ. 

Industry Net-Output Price Indexes 

PPIs for the net output of industries and their products are grouped according to the North American Industry Classification 

System (NAICS). Prior to the release of January 2004, industry-based PPIs were published according to the Standard Industrial 

Classification (SIC) system. Industry price indexes are compatible with other economic time series organized by industry, such as 

data on employment, wages, and productivity. Table 5 of the PPI Detailed Report includes data for NAICS industries and industry 

groups (3-, 4-, 5-, and 6-digit codes); Census product classes (7- and 8-digits), products (9-digits), and more detailed subproducts (11-

digits); and, for some industries, indexes for other sources of revenue. 

 Indexes may represent one of three kinds of product indexes. Every industry has primary product indexes to show changes in 

prices received by establishments classified in the industry for products made primarily, but not necessarily exclusively, by that 

industry. The industry classification of an establishment is determined by which products comprise a plurality of its total shipment 

value. In addition, most industries have secondary product indexes that show changes in prices received by establishments classified 

in the industry for products chiefly made in some other industry. Finally, some industries have miscellaneous receipts indexes to show 

price changes in other sources of revenue received by establishments within the industry that are not derived from sales of their 

products, for example, resales of purchased materials, or revenues from parking lots owned by a manufacturing plant. 
Data Collection 

PPIs are based on selling prices reported by establishments of all sizes selected by probability sampling, with the probability

of selection proportionate to size. Individual items and transaction terms from these firms are also chosen by probability proportionate 

to size. The BLS strongly encourages cooperating companies to supply actual transaction prices at the time of shipment to minimize 

the use of list prices. Prices submitted by survey respondents are effective on the Tuesday of the week containing the 13th day of the 

month. This survey is conducted primarily through the mail. 

 Price data are provided on a voluntary and confidential basis; only sworn BLS employees are allowed access to individual 

company price reports. BLS publishes price indexes instead of unit dollar prices. All PPIs are subject to revision 4 months after 

original publication to reflect the availability of late reports and corrections by respondents. 

 BLS periodically updates the PPI sample of survey respondents to better reflect current conditions when the structure, 

membership, technology, or product mix of an industry shifts significantly and to spread reporting burden among smaller firms. 

Results of these resampling efforts are incorporated into the PPI with the release of data for January and July. 

 As part of an ongoing effort to expand coverage to sectors of the economy other than mining and manufacturing, an 

increasing number of service sector industries have been introduced into the PPI. The following list of recently introduced industries 

includes the month and year in which an article describing the industry’s content appeared in the PPI Detailed Report.

Weights

Weights for most traditional commodity groupings of the PPI, as well as weights for commodity-based aggregate indexes 

calculated using traditional commodity groupings, such as stage-of-processing indexes, currently reflect 1997 values of shipments as 

reported in the Census of Manufactures and other sources. From January 1996 through December 2001, PPI weights were derived 

from 1992 shipment values. Industry indexes also are now calculated with 1997 net output weights. This periodic update of the value 

weights used to calculate the PPI is done to more accurately reflect changes in production and marketing patterns in the economy. Net 

output values of shipments are used as weights for industry indexes. Net output values refer to the value of shipments from 

establishments within the industry to buyers outside the industry. However, weights for commodity price indexes are based on gross 

shipment values, including shipment values between establishments within the same industry. As a result, broad commodity grouping 

indexes, such as the PPI for All Commodities, are affected by the multiple counting of price change at successive stages of processing, 

which can lead to exaggerated or misleading signals about inflation. Stage-of-processing indexes partially correct this defect, but 

industry indexes consistently correct for this at all levels of aggregation. Therefore, industry and stage-of-processing indexes are more 

appropriate than broad commodity groupings for economic analysis of general price trends. 

Price Index Reference Base 

Effective with publication of January 1988 data, many important PPI series (including stage-of-processing groupings and 

most commodity groups and individual items) were placed on a new reference base, 1982=100. From 1971 through 1987, the 

standard reference base for most PPI series was 1967=100. Except for rounding differences, the shift to the new reference base did 

not alter any previously published percent changes for affected PPI series. (See “Calculating Index Changes,” below.) The 1982 

reference base is not used for commodity indexes with a base later than December 1981 or for industry net output indexes and their 

products. 

 For further information on the underlying concepts and methodology of the Producer Price Index, see chapter 14, “Producer 

Prices,” in BLS Handbook of Methods (April 1997), Bulletin 2490. This document can be downloaded from the BLS Web site at 

(http://www.bls.gov/opub/hom/homch14_itc.htm), and reprints are available on request. 

Calculating Index Changes 

Each PPI measures price changes from a reference period which equals 100.0. An increase of 5.5 percent from the reference 

period in the Finished Goods Price Index, for example, is shown as 105.5. This change also can be expressed in dollars, as follows: 

Prices received by domestic producers of a sample of finished goods have risen from $100 in 1982 to $105.50. Likewise, a current 

index of 90.0 would indicate that prices received by producers of finished goods are 10 percent lower than they were in 1982. 

 
Movements of price indexes from one month to another are usually expressed as percent changes, rather than as changes in 

index points. Index point changes are affected by the level of the index in relation to its base period, whereas percent changes are not. 

The following example shows the computation of index point and percent changes. 

Index point change

Finished Goods Price Index 107.5 

Less previous index 104.0 

Equals index point change 3.5 

Index percent change

Index point change 3.5 

Divided by the previous index 104.0 

Equals 0.034 

Result multiplied by 100 0.034 x 100 

Equals percent change 3.4 

Seasonally Adjusted and Unadjusted Data 

Because price data are used for different purposes by different groups, BLS publishes seasonally adjusted and unadjusted 

changes each month. Seasonally adjusted data are preferred for analyzing general price trends in the economy, because these data 

eliminate the effect of changes that normally occur at about the same time, and in about the same magnitude, every year—such as

price movements resulting from normal weather patterns, regular production and marketing cycles, model changeovers, seasonal 

discounts, and holidays. For these reasons, seasonally adjusted data more clearly reveal underlying cyclical trends. Unadjusted data 

are of primary interest to users who need information that can be related to actual dollar values of transactions. Individuals requiring 

this information include marketing specialists, purchasing agents, budget and cost analysts, contract specialists, and commodity 

traders. It is the unadjusted data that are generally cited when escalating long-term contracts such as purchasing agreements or real 

estate leases. (See Escalation and Producer Price Indexes: A Guide for Contracting Parties, BLS Report 807, September 1991, 

available on request from the BLS.) 

In 1998, the PPI implemented the X-12-ARIMA Seasonal Adjustment Method; prior to that year the PPI employed the X-11 

method. Each year, the seasonal status of most commodity indexes is re-evaluated to reflect more recent price behavior. Industry net 

output indexes are not seasonally adjusted. For time series that exhibit seasonal pricing patterns, new seasonal factors are estimated 

and applied to the unadjusted data for the previous 5 years. These updated seasonally adjusted indexes replace the most recent 5 years 

of seasonal data. 

 Seasonal factors may be applied to series using either a direct or aggregative method. Generally, commodity indexes are 

seasonally adjusted using direct seasonal adjustment, which produces a more complete elimination of seasonal movements than the

aggregative method. However, the direct seasonal adjustment process may not yield figures that possess additive consistency. Thus, a 

seasonally adjusted index for a broad category that is directly adjusted may not be logically consistent with all seasonally adjusted 

indexes for its components. Seasonal movements for stage-of-processing indexes are derived indirectly through an aggregative 

method that combines movements of a wide variety of subproduct class (6-digit) series. 

Seasonally adjusted indexes can become problematic when previously stable and predictable price patterns abruptly change. 

If the new pattern persists, the seasonal adjustment method will eventually reflect it adequately; if these patterns keep shifting, 

however, seasonally adjusted data will become chronically troublesome. This problem occurs relatively infrequently for farm and 

food-related products but has more often affected manufactured products such as automobiles and steel. 

Since January 1988, the PPI has used Intervention Analysis Seasonal Adjustment methods to enhance the calculation of 

seasonal factors. With this technique, outlier values that may distort the seasonal pattern are removed from the data prior to applying 

the standard seasonal factor estimation procedure. For example, a possible economic cause for large price movements for petroleumbased products might have been the Persian Gulf War. In this case, intervention techniques allowed for better estimates of seasonally 

adjusted data. On the whole, very few series have required intervention. Out of nearly 900 seasonally adjusted series, only 16 

interventions were performed in 1997. 

For more information relating to seasonal adjustment methods, see (1) “Appendix A: Seasonal Adjustment Methodology at 

BLS,” in the BLS Handbook of Methods (April 1997), Bulletin 2490 and (2) “Summary of Changes to the PPI’s Seasonal Adjustment 

Methodology” in the January 1995 issue of Producer Price Indexes. 

Producer Price Index Data Via the Internet 

In 1995, the BLS began posting PPI series, news releases, and technical information to both a World Wide Web (WWW) site 

and a file transfer protocol (FTP) site. During the years following the introduction of PPI Internet services, usage of these sites 

eclipsed more traditional methods of data dissemination, such as subscriptions to the PPI Detailed Report. There were more than 1.6 

million accesses of PPI series over the Internet during the 12 months ended December 31, 2003. 
Retrieving PPI data from the PPI Website 

PPI data can be obtained from the WWW address (http://www.bls.gov/ppi). Scrolling down the page to the “Get Detailed 

Statistics” header reveals the following 5 methods of data retrieval: 

• Most Requested Series is a form-based application that allows the user to quickly obtain PPI time series data by selecting from 

two separate lists (commodity and industry) of the most commonly requested time series, including the All Commodities Index and

the stage-of-processing indexes (for example, Finished Goods). Within each list, any one—or all—of the time series shown can be 

selected. A user can modify the date range and output options after executing the query, using the reformat button above the data 

output table. 

• Create Customized Tables is a form-based query application designed for users unfamiliar with the PPI coding structure. It 

guides a user through the PPI classification system by listing index titles and does not require knowledge of commodity or industry 

codes. Data retrieved are based on a query formulated by selecting data characteristics from lists provided. Two options are available 

to create customized tables, depending on a user’s browser capability. The one-screen option is a JavaScript application that uses a 

single screen to guide a user through the available time series data. The second option is a multiple screen, nonJava-based application. 

Both methods allow a user to browse the PPI coding structure and select multiple series codes. Using the one-screen option, users can 

modify the date range and output options after executing the query using the reformat button above the data output table. 

• Series Report is a form-based application that uses formatted PPI time series identifiers (commodity or industry codes) as input in 

extracting data according to a specified set of date ranges and output options. This application provides the most efficient path for 

those users who are familiar with the format of PPI time series identifiers. Up to 300 indexes can be extracted at one time. 

 There are three basic formats for creating a unique PPI time series identifier. For commodity and stage-of-processing indexes, 

enter a “wpu” prefix (not seasonally adjusted) or a “wps” prefix (seasonally adjusted) in combination with a commodity-based code to 

create a series identifier. 

Commodity code Will provide data for:

wps063 Drugs and pharmaceuticals, seasonally adjusted 

wpu063803 Pharmaceutical preparations, cardiovascular system 

wpusop3000 Finished goods, not seasonally adjusted 

For a current industry-based price index organized according to the North American Industry Classification System (NAICS), enter 

the prefix “pcu” followed by the industry-product code. The series identifier for products primary to an industry include 12 numeric 

digits, the six-digit industry code is repeated, and up to seven additional digits of product detail. Dashes are used as place holders for 

higher-level industry group codes. 

Industry-product code, Will provide data for:

Current NAICS series 

pcu325---325--- Chemical manufacturing, not seasonally adjusted 

pcu336110336110 Automobile and light duty motor vehicle manufacturing 

pcu621111621111411 Offices of physicians, one and two physician practices and single specialty group practices, 

general/family practice 

To identify a discontinued industry-product code based on the Standard Industrial Classification (SIC), enter a “pdu” prefix and “#” 

between the fourth and fifth characters of the product code. A series identifier for the discontinued dataset uses underscores as 

placeholders to complete a reference to an SIC industry group code of less than four digits. (All PPI industry-based indexes organized 

by SIC were discontinued with the introduction of the NAICS.) In all cases, no spaces are permitted. 

Industry-product code, Will provide data for:

Discontinued SIC series 

pdu28__# Chemicals and allied products, not seasonally adjusted 

pdu331_# Blast furnaces, steel works, and rolling and finishing mills, not seasonally adjusted 

pdu3711#111 Passenger cars 

• Flat Files and the FTP server are best suited for those users requiring access to either a large volume of time series data or other 

PPI-related documentation (such as, seasonal factor and relative importance tables). The FTP site can be accessed at 

(ftp://ftp.bls.gov) or directly from the links on the “Get Detailed Statistics” page or the PPI homepage. Data and documentation 

available for download include: 

 Directory: 

• NAICS Current Series /pub/time.series/pc 

• SIC Discontinued Series /pub/time.series/pd 

• Commodity Series /pub/time.series/wp

• Special Requests /pub/special.requests/ppi

• Latest News Release /pub/news.release/ppi.txt
The FTP site maintains files to help with searches and downloads. These files are centrally located in the /pub/doc directory. 

Within this directory, go to the overview.txt file for an overview relating to all BLS data available through the FTP site. For 

commodity-based PPI data (which appear in tables 1, 2, 3, 6, 7, and 8 of the PPI monthly detailed report and tables 1, 2, 3, and 5 of the 

monthly news release), the program help file is wp.txt. For current industry-based PPI data based on the NAICS (which appear in 

tables 4, 5, and 9 of the monthly PPI report and table 4 of the monthly news release), the file is pc.txt. For industry-based SIC time 

series that have been discontinued, go to pd.txt. (These and other help files are also maintained within each of the five directories 

listed above.) 

Other Sources of PPI Data 

PPI data can also be accessed via the BLS homepage (http://www.bls.gov). After clicking the “Get Detailed Statistics” link 

at the top of the homepage a chart appears listing all of the available BLS programs. The following four methods are available for PPI 

data: Most requested statistics, create customized tables (one screen or multiple screens), and flat files. Additional sources of BLS 

data also are accessible from this page including: Economic news releases, series report, and economy at a glance. 

 

Additional information 

The PPI homepage (http://www.bls.gov/ppi) contains additional information regarding PPI data and methodology. The top 

section of the homepage provides PPI news releases, both current and archived, as well as general PPI information. The “Tables

Created by BLS” section found beneath the statistics section provides relative importance and seasonal factor tables. The remaining 

sections offer special notices and publications pertaining to PPI methodology and applications. 

For questions or comments regarding PPI data classification, methodology, or data availability on the Internet, call or e-mail
