This numerical list includes the principal products and services of the manufacturing and mining industries in the United

States. The data for these products and services were collected in the 2012 Economic Census - Manufacturing on 263

long forms (MC-31101 through MC-33917) and 29 short forms (MC-31171 through MC-33975) and in the 2012 Economic

Census - Mining on 17 long forms (MI-21101 through MI-21352) and 2 short forms (MI-21171 and MI-21271). Each 

report covers one industry or more and includes a product inquiry which lists the primary products of the industries as 

well as the chief secondary products frequently reported by establishments classified in the industries on the form.

There are approximately 4,392 products (ten-digit codes) for which information is published in the manufacturing 

and mining sectors. The new system contains about 1,434 manufacturing and mining product classes 

(seven-digit codes).

NAICS United States industries are identified by a six-digit code. The six-digit code accommodates the large number of 

sectors and allows more flexibility in designing subsectors. Each product or service is assigned a ten-digit code. 

The product coding structure represents an extension, by the U.S. Census Bureau, of the six-digit industry classifications

of the manufacturing and mining sectors. The classification system operates so that the industrial coverage is 

progressively narrower with the successive addition of digits. This is illustrated as follows:

NAICS level NAICS code Description

Sector 31-33 Manufacturing

Subsector 334 Computer and electronic product manufacturing

Industry group 3346 Manufacturing and reproducing magnetic and optical 

media

Industry 33461 Manufacturing and reproducing magnetic and optical 

media

U.S. Industry 334614 Software and other prerecorded compact disc, tape, 

and record reproducing

Product class 3346142 Reproduction of recording media

BLS link code 33461422 Audio Tapes, casette full-length

Product code 3346142201 Audio Tapes, casette full-length

These files attempt to preserve the historical comparability between the 2012 and 2007 censuses for product classes 

and product codes in Appendixes B and C.

content is the same as it was published in 2007.

The U.S. Census Bureau terminated the collection of data for the Current Industrial Report (CIR) program in 

September 2011. In preparation for the FY 2012 budget, the Census Bureau did a comprehensive review of a number 

of programs. The review concluded it necessary to terminate and reduce some existing programs in order to secure

funding for new programs and manage cyclical increases for other data collection programs. The Census Bure

consulted with key federal data users on relative program priorities and specifically about the consequences of 

terminating the CIR program. While few data users wanted to eliminate this existing data source, the availabilit

of manufacturing data from the Annual Survey of Manufactures and the 5-year Economic Census, help mitigat

the loss of the CIR data products. 

The product code column, which includes codes used in the 2012 publications, is based on the NAICS structure. The 

ninth and tenth digits of the product code taken together are unique and identify the product. (Occasionally, the ninth

digit will be similar for a group of related products within the same product class but the ninth digit by itself is not 

significant.)

These product and service codes are arrayed (generally) in ascending numerical order within their respective seven-digit 

product classes: the product classes within their six-digit U.S. industries; where applicable, six-digit U.S. industries

within the respective five-digit industry grouping; and five-digit industry groupings within three-digit NAICS subsectors. 

NAICS subsectors, industry groupings, and U.S. industries are titled in accordance with the long NAICS titles shown in 

Part II, Numerical List of Short Titles, North American Industrial Classification System, 2012. Descriptions of product

classes, eight-digit BLS link codes, and ten-digit products have been developed by the U.S. Census Bureau.

This document contains three appendixes. Appendix A contains codes used on the census forms to collect 

miscellaneous detailed statistics data for selected nonmanufacturing and nonmining activities. Appendixes B and C 

illustrate the relationship between the 2012 and 2007, and the 2007 and 2007 product classes and product codes, 

respectively.

The phrase ‘‘To be spec’’ indicates that the unit of measure is specified by the reporting establishment. The abbreviation

 ‘‘nsk’’ means not specified by kind.
