Which code does this activity belong in?
Wood Preservation comprises establishments that treat wood products with chemical preservatives to protect against decay, fire, and insects, as well as those that saw and treat round wood poles, pilings, and posts. The boundary with Sawmills lies in the treatment step: establishments that only saw lumber from logs without applying preservatives are classified in Sawmills, while those performing the preservation treatment function belong in Wood Preservation, regardless of whether they also perform the initial sawing operation.
