National Classifications


Country / Area: United States of America

Classification category: Product classifications

General information
1 (a)Name of the current national classification (full name in official national languages and in English with acronyms in brackets, should be given)We will continue to link, when possible, the products in NAPCS product lists to CPC products throughout the NAPCS development program.
1 (b)In which language(s) is the classification available?The NAPCS is generally more detailed than the CPC and its products are identified and defined with extensive outreach to industry experts (more than 300 in U.S. to date). The NAPCS development process identifies and defines the products of industries rather than industry-defined revenue categories as is sometimes the case with the CPC. See, for example, the CPC (1.0) product list for Telecommincation Services (Division 84). Here CPC (1.1) incoporated product detail taken from NAPCS product list for NAICS 517 except 5175.
1 (c)Can the classification (or information about it) be accessed on the Internet? If yes, please provide the URL.The overall NAPCS structure is under development but does not exist yet. Unlike existing systems, however, it is anticipated that the NAPCS will be designed around a single unifying principle for grouping and aggregating products based on a demand-based aggregation principles. Moreover, NAPCS will not be an industry-of-origin classification system. Ultimately, all products identified in the industry product list will be arranged in the overall NAPCS structure. The product lists developed to date contain as many as seven levels.
Classification structure
2 (a)Please describe the structure of the classification: How many levels does the classification have? (Please provide labels, such as “Division”, “Class”) How many categories exist at each level?Since the system is in development, the number of products is unknown, and since this is a trilateral effort, the number of detailed products varies by country. However, at the present time 33 provisional product lists have been completed and 3 others are in the final review stage. These lists cover the products of some 117 US service industries, and they identify and define nearly 1200 trilateral products and approximately 1000 US national products below the trilateral level.
2 (b)Please provide examples of the coding system used at each level.No, the system is still in development. However, we are including CPC links for each of the products in our product lists.
Relationship to international standards
3 (a)Is this classification based on (or linked to) an international standard classification? If yes, please describe.The ECPC (Economic Classification Policy Committee)

Washington, DC 20503
3 (b)Is the classification structure identical to the international standard or, if not, how does it differ? (e.g. have additional levels been added to the international standard or have changes been made within the level of the international structure, such as aggregations or additional breakdowns)John Burns Murphy
Chairperson, ECPC

3 (c)Please describe deviations from the international standard (in terms of structure, methodology or application rules). Please use examples, if a general statement is not possible.Michael F. Mohr

Tel: (301) 457- 2589,

The NAPCS Website (http://www.census.gov/napcs) contains detailed background information on NAPCS and on 26 of the product lists completed to date.

3 (d)At what level of the international standard can data be reported for international comparison? (Please provide examples of programmes / indicators if reporting takes place at different levels of the classification.)Planned completion of product lists for the service industries is 2005; a target date for including goods in NAPCS has not yet been determined. To date, work has been completed for the majority of industries in 4 NAICS sectors (Phase I of NAPCS): Information; Finance and Insurance; Professional; Scientific and Technical Services; and Administrative and Support and Waste Management and Remediation Services. To field test the collectability of data for these products, many of them were incorporated into the 2002 Economic Census; some were incorporated in the 2001 Services Annual Survey, and the otheres will be progressively incorporated in subsequent Services Annual Surveys. In addition, we are presently developing product lists for the industries in 5 more NAICS sectors (Phase II of NAPCS): Transportation and Warehousing, Education; Health Care and Social Services; Arts, Entertainment, and Recreation; and Accommodation and Food Services.
3 (e)If no links to international classifications exist or no international standard is used, please state if there are plans to use international norms in the future.After the classification system is developed and official, it will be maintained and revised on a regular cycle.
Classification uses
4 (a)Please state for which statistical purposes (surveys etc.) this classification is used and if there are users outside of the Statistical Office. Please indicate at which level the classification is used for data collection and for data publishing.In the US, the Census Bureau will use this classification system in the quinquennial economic census and in current annual surveys starting with 2002. Users outside of the Census Bureau will be the Bureau of Economic Analysis (BEA) and the Bureau of Labor Statistics (BLS).
4 (b)Please give the names of institutions that use the classification for non-statistical purposes (as opposed to statistical purposes in question 4(a)). Also indicate the kind of use (e.g. tax offices, social security, customs, enterprise register, employment services, work permits etc.)For the Census Bureau’s Economic Censuses and the current annual surveys, the level of detail will be somewhere between the minimum comparable 3-country level of detail and the maximum full US detail on the entire list of products.
4 (c)Please indicate if alternative classifications are used by other institutions of the economy. Are these classifications available and useful for the Statistical Office?NAPCS-defined product data for industries classified in NAICS sector 51 (except 512 and 516 industries) and in NAICS 5415 was experimentally collected in the 2001 Services Annual Survey. This data was just publised on the internet and can be located at the following addressess: http://www.census.gov/svsd/www/sas51.html and
In addition data, the 2002 Economic Census is presently attempting to collect NAPCS-defined product data for more than 80 industries.
Implementation / revision status
5 (a)Please state the date of the official adoption of the classification. If not yet adopted, please indicate the current state (e.g. in development, sent for approval, in printing, ready to be distributed etc.)The US version of NAPCS will be in English only.
5 (b)Please state the date of use of the classification for individual statistical programmes.No
5 (c)Are there existing plans for revision or update of the current classification?No
5 (d)Name of former (previous) national classification (full name in both national tongue and in English with acronyms in brackets, should be given)No- system still in development.
5 (e)Please describe the link of the former classification to international classificationsWe have just begun collection of NAPCS-defined products. We will evaluate for problems when the data collection process is complete.
5 (f)Please describe the structure of the former classification and indicate the number of items at each level of the classification. (similar to question 2(a))Assistance from international organizations is not needed at this time.
5 (g)Do conversion tables exist between the former and current classification?It is expected that affected companies and professional organizations will use the classification system in their analytical programs related to competitiveness, market share, and trade, etc.
5 (h)When was the former classification implemented?Some of the systems in use are the CPC, the International Harmonized Commodity Description and Coding System (HS), the Producer Price Index Program (PPI) and the Treasury Management Association (TMA) codes. All of these systems are available and useful to our statistical office.
5 (i)Are statistical data still collected or published according to the former classification? Please indicate if this statistical data is collected or published by the Statistical Office or elsewhere.Conversion tables are not available at this time.
Supporting documents
6 (a)Have national explanatory notes and/or guidelines been elaborated?With the exception of product codes for goods, there was no previous classification system for service products in the United States. Prior to 2002, the Economic Census for service industries used a loose collection of revenue lines as opposed to "products."
6 (b)Do correspondence tables exist between the national and the international classifications (if applicable)?N/A
6 (c)Are correspondence tables between alternative and current classification available (if applicable)?N/A
6 (d)Does a national coding index exist?N/A
6 (e)Is the classification available in electronic form? If yes, in which formats is it available?(e.g. PDF, TXT, Excel, XML)N/A
6 (f)Are the correspondence tables or indexes available in electronic form?N/A
Contact information
7 (a)Name of institution / office responsible for the development and maintenance of the classificationCurrently, the current business surveys and the economic censuses are collected and published according to the old system of revenue lines. Some of these collected items are used as input to the National Accounts.
