North American Product Classification System (NAPCS)


The North American Product Classification System (NAPCS) is a comprehensive, market- or demand-based, hierarchical classification system for products (goods and services) that (a) is not industry-of-origin based but can be linked to the NAICS industry structure, (b) is consistent across the three North American countries, and (c) promotes improvements in the identification and classification of service products across international classification systems, such as the Central Product Classification System of the United Nations. For more information, see discussion paper, "Overview of NAPCS Objectives, Guidance, and Implementation Strategy and Goals: A United States Perspective." The three countries agreed that the objectives and principles articulated in sections A through C of that paper define the purposes of NAPCS and the operational guidelines for creating it. Also see additional papers under the NAPCS History tab and Frequently Asked Questions about NAPCS under the FAQs tab.
