These establishments produce lumber that may be rough, or dressed by a planing machine to achieve smoothness and uniformity of size, but is generally not further worked or shaped. Establishments that preserve wood are also included.

  • Exclusion(s):

    Establishments primarily engaged in:

    • chipping logs in the field (See 11331 Logging)
    • manufacturing glued-laminated timber, nailed-laminated lumber beams, parallel strand lumber, laminated veneer lumber, fingerjoined lumber, and similar products (See 32121 Veneer, Plywood and Engineered Wood Product Manufacturing)
    • peeling or slicing logs to make veneer (See 32121 Veneer, Plywood and Engineered Wood Product Manufacturing)
    • planing purchased lumber or working lumber further than dressed (See 32191 Millwork)

    • Lumber (i.e., rough, dressed), made from logs or bolts
    • Lumber, hardwood dimension (e.g., 2x4), made from logs or bolts
    • Lumber, softwood dimension (e.g., 2x4), made from logs or bolts
    • Sawdust and shavings, made from logs or bolts (i.e., in a sawmill)
    • Sawmills
    • Siding, dressed lumber, manufacturing
    • Snow fence lath, made from logs or bolts
    • Ties, railroad, made from logs or bolts
    • Timbers, made from logs or bolts
    • Wood chips, made in sawmills

321112 - Shingle and Shake MillsMEX

This Canadian industry comprises establishments primarily engaged in sawing blocks of wood to produce shingles or splitting blocks of wood to produce shakes.

  • Example Activities:

    • Shakes (i.e., hand split shingles), manufacturing
    • Shingle mills, wood

321114 - Wood PreservationUS

This Canadian industry comprises establishments primarily engaged in treating lumber, plywood, poles and similar wood products, produced in other establishments, with preservatives to prevent decay and to protect against fire and insects. Establishments primarily engaged in cutting to size and treating poles, pilings, posts and similar roundwood products are included. Pressure treating is the most common method used. Some common preservatives are water-borne inorganic compounds, such as chromated copper arsenate and creosote.

  • Example Activities:

    • Creosoting of wood
    • Lumber, treating with creosote or other preservatives
    • Piles, foundation and marine construction, treating
    • Plywood, treating with creosote or other preservatives
    • Pressure treated plywood, made from purchased plywood
    • Railroad ties (i.e., bridge, cross, switch), wood, treating
    • Treating wood products with creosote or other preservatives
