The data published with NAICS code 321912 include the following SIC industries:
2421 Sawmills and planing mills, general (pt)
2426 Hardwood dimension and flooring mills (pt)
2439 Structural wood members, n.e.c. (pt)
2499 Wood products, n.e.c. (pt)
This definition comes from the 1997 NAICS manual. However, for this industry, the 1997 Economic Census Manufacturing implemented the conversion to NAICS differently. Data for NAICS industry 321912 include establishments primarily engaged in the manufacture of hardwood dimension made from logs and bolts, lumber members made from purchased lumber, and semi-machined and fully-machined softwood dimension lumber, but do not include establishments primarily engaged in the manufacture of staves from purchased lumber. The NAICS definitions will be fully implemented with the 2002 Economic Census.
