Cut Stock, Resawing Lumber, and Planing
NAICS 321912 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in one or more of the following: (1) manufacturing dimension lumber from purchased lumber; (2) manufacturing dimension stock (i.e., shapes) or cut stock; (3) resawing the output of sawmills; and (4) planing purchased lumber. These establishments generally use woodworking machinery, such as jointers, planers, lathes, and routers to shape wood.
Start the review with fire and combustible dust.
For Cut Stock, Resawing Lumber, and Planing, the saved research highlights fire and combustible dust, workers' compensation, equipment breakdown. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What dust collection and suppression systems are in place, and how frequently are they maintained and cleaned?
- Is the facility sprinklered, and what is the construction type of the main production building?
- What types of machinery are in operation — planers, resaws, lathes, routers — and what are their approximate replacement values?
- Are any kiln drying, chemical treatment, or finishing operations performed on-site?
- What is the total value of raw and finished lumber inventory typically on hand?
- Prior loss history, particularly any fire events or workers' comp claims involving machinery?
- For Cut Stock, Resawing Lumber, and Planing, what should the underwriter know about lack of a functioning dust collection and suppression system, or evidence of heavy sawdust accumulation throughout the facility?
- For Cut Stock, Resawing Lumber, and Planing, what should the underwriter know about non-sprinklered or combustible-construction building housing significant lumber inventory and production machinery?

These establishments process purchased lumber using industrial woodworking machinery — planers, jointers, lathes, routers, resaws, and similar equipment — to produce dimensioned lumber, cut stock, and shaped wood components. Output is typically sold to manufacturers, millwork fabricators, or construction supply channels rather than retail consumers. Sawdust, wood shavings, and fine particulate accumulation are a constant byproduct of daily operations.
