North American Product Classification System

In February 1999, the statistical agencies of Canada, Mexico, and the United States launched a joint multi-phase initiative to develop a comprehensive demand-oriented product classification, known as the North American Product Classification System (NAPCS). Work to date has focused on the products produced by service industries in 12 NAICS sectors 48-49 through 81. With that work nearing completion, this web page provides an overview of and progress report on the NAPCS initiative and presents the final versions of the product lists developed so far for the service industries included in those 12 sectors.
