The data published with NAICS code 322121 include the following SIC industries:

This definition comes from the 1997 NAICS manual. However, for this industry, the 1997 Economic Census Manufacturing did not fully implement the conversion to NAICS. Data for NAICS industry 322121 include paper mills which convert sanitary paper stock into sanitary paper products, but do not include paper mills which are primarily engaged in the manufacture of other converted paper products. The NAICS definitions will be fully implemented with the 2002 Economic Census.
