After designing a new industrial classification system, the three countries are faced with the task of how to implement this system. Delayed use can only worsen the inherent problems of the original system, so the designers participating in NMCS decided to apply NAICS as soon as possible.

The Census Bureau agreed to implement the new classification system for the 1997 Economic Census, and the scheduled date for the census to start data collection was less than a year before the final approval of the NMCS. ③The Census Bureau plans to publish new general statistical progress data using the NMCS system in early 1999. Beginning in the second quarter of 1999, geographical area reports and professional series reports using only NMCS industry classifications were published. Finally, it is planned to publish a join classification relationship table in March 2000, allowing users to connect NMCS statistics with data published using SIC coding.

[③The Bureau of Economic Analysis (BEA) and the Bureau of Labor Statistics (BIN) also plan to implement NAICS as soon as possible; the initial data published by BEA will be the 1997 Foreign Direct Investment Benchmark Survey (data collected in 1999), and BIN in 2002 Begins to publish data based on NAICS (2001 Annual Employment and Wage Report). ]

There are several elements of the 1997 Economic Census that are not converted to NAICS, including: the Economic Census of remote areas (Puerto Rico, Guam, and the U.S. Virgin Islands), the Commodity Flow Survey, and the Automobile Stock and Usage Survey. Regular economic survey projects of the Census Bureau, such as the 1998 Annual Manufacturing Survey (data are planned to be released using NMCS in March 2000), the monthly wholesale and retail trade industry surveys (both planned in 2001), and the 1999 Annual Capital Expenditure Survey (2001 February 2000), quarterly financial reports (March 2001, the fourth quarter report of 2000), etc. will all start to use NMCS classification after the 1997 census.
