Analysis
NAICS 321215 is the 2022 national industry for engineered wood member manufacturing, part of 32121 (Veneer, Plywood, and Engineered Wood Product Manufacturing). Census lists 18 example activities under it in the official index.
Its index entries, the activities Census uses to assign businesses to this code, include arches, glue laminated or pre-engineered wood, manufacturing, fabricated structural wood members manufacturing, finger joint lumber manufacturing and floor trusses, wood, manufacturing, among 18 in all.
For example, manufacturing prefabricated wood buildings or wood sections and panels for buildings are classified in 321992 (Prefabricated Wood Building Manufacturing) instead.
Census lists 2 related activities that belong elsewhere, most often in 321992 and 321113. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.
County Business Patterns publishes no national count for it, either because the code is out of the survey's scope or because the figures are suppressed to protect individual businesses.
