Introduction to 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

                        tab. View more In February 1999, the statistical agencies of Canada, Mexico, and the United States launched
                            a joint multi-phase initiative to develop NAPCS. In planning the NAPCS initiative, the three
                            countries began with a consensus on the proposition that improved product data for service
                            industries is critical to improving vital economic measures related to measuring the growth
                            of output, prices, productivity, and trade. In recognition of this fact, NAPCS work first
                            focused on identifying and defining the products produced by industries in the 12 NAICS
                            service sectors from Sector 48-49 through Sector 81. Embodying research conducted by 13
                            trilateral working groups, with extensive input from industry experts, this effort was
                            implemented in three phases and was completed in 2009. **Phase I** was launched in early 1999 to explore the feasibility of identifying
                            and defining service products across the three countries, and it focused on the products
                            produced by industries in four NAICS service sectors: Sector 51: Information, Sector 52:
                            Finance and Insurance, Sector 54: Professional, Scientific, and Technical Services, and
                            Sector 56: Administrative and Support and Waste Management and Remediation Services. Phase I
                            generated 36 product lists that cover the final products produced by 117 US service
                            industries. Products from 26 of these lists were incorporated into the 2002 Economic Census,
                            and some were incorporated into the 2001 and subsequent Services Annual Surveys. Based on
                            the success of Phase I, the three countries agreed that the NAPCS should continue and be
                            expanded to cover the products of industries in all NAICS service sectors from Sector 48-49
                            through Sector 81 (excluding those in Sector 814, Private Households, and Subsector 525,
                            Funds, Trusts, and Other Financial Vehicles). **Phase II**, launched in July 2001, extended NAPCS to the industries in five
                            additional NAICS service sectors: Sector 48-49: Transportation and Warehousing, Sector 61:
                            Educational Services, Sector 62: Health Care and Social Assistance, Sector 71: Arts,
                            Entertainment and Recreation, and Sector 72: Accommodation and Food Services. **Phase III** was launched in May 2004, and it extended NAPCS to industries not
                            covered in the sectors addressed under Phases I and II and to industries in Sector 53: Real
                            Estate and Rental and Leasing, Sector 55: Management of Companies and Enterprises, and
                            Sector 81: Other Services (except Public Administration). Taken together, Phases II and III
                            researched the final products produced by more than 250 US service industries. The products developed under Phases I - III are assembled into 102 product lists that
                            identify and define the significant products produced by about 370 US service industries.
                            These lists include 98 that are at the trilateral level; three at the bilateral level (US
                            and Mexico for NAICS 55-Management of Companies and Enterprises, NAICS 621210-Offices of
                            Dentists, and NAICS 621610-Home Health Care Services); and one at the US-only level (for
                            NAICS 621-2 (except 6212, 6, and 9)-Health Care Services of Physicians, Health Care
                            Practitioners (except Dentists) and Hospitals). Product lines developed from all 102 lists
                            were incorporated into product collection forms developed for the 2007 and 2012 Economic
                            Censuses, and they were incorporated incrementally into the Service Annual Survey (beginning
                            in 2001). The 102 product lists can be viewed in PDF file format (PDF files) using links on

                            unduplicating products of NAICS industries, and in some cases, renegotiating trilateral
                            products to align with the demand-oriented concept. The 2017 and 2022 NAPCS structures can be viewed
