California Lumber Products Assessment

Department of Commerce. Canadian softwood lumber imported into the U. For purposes of grading, softwood lumber may be categorized into two categories of intended use: construction or remanufacture. Construction lumber is lumber that will function as graded and sized after primary processing — sawingsurfacing, etc.

It is commonly available in producgs lumber yards and definitikn as the primary softwood resource for many woodworkers. Lumber for remanufacture can be expected to undergo secondary manufacturing to create a product that may differ markedly from the original graded piece. Industrial operations are the typical users of this type of lumber.

Some examples include stock for pencils, ladders, poles, boxes, and moulding. Most softwood lumber is sold as construction lumber and that will be the definition softwood lumber products test of the following discussion. Lumber intended for general construction purposes may be subdivided into stress-gradednonstress-gradedand appearance lumber. For stress-graded and nonstress-graded lumber, the structural integrity of the wood is the primary requirement in the grading process.

With appearance lumber, the appearance or visual quality of the piece is most important and structural integrity is of secondary importance. This is the type of lumber that peoducts woodworkers utilize. With such lumber, grading is done on dwfinition better side of a piece after drying and surfacing, and grades are designated by specifying the allowable size and number of defects e.

This contrasts with hardwoods where most grades are determined definition softwood lumber products test the poorer side of each piece on the basis of a specified number of clear cuttings.

Another distinction is that hardwoods are typically graded prior to drying and surfacing. With nonstress-graded lumber, pieces are graded primarily for serviceability but appearance is also considered, especially in the higher grades. Imperfections such as knots and knotholes are allowed to become larger and osftwood frequent as the grade drops.

The primary product is boards that are less than 2 inches in nominal thickness and 2 inches or more in nominal width. Common nominal widths are 2- 3- 4- 6- 8-,and inches. Lengths are usually from 6- to feet in increments of 2 feet. Boards may be sold square-edged, tongue-and-grooved, or shiplapped. Three to five different Common grades may be applied to boards in this group depending upon the species and the lumber manufacturing association involved.

In descending order of quality, the grades are No. The first three grades are most commonly available in retail lumber yards. Paints well. Used for siding, cornice, shelving, paneling, some furniture. Paints fair. Similar uses as No.

Does not take paint well. Used for crates, sheathing, subflooring, small furniture parts. Large waste areas. Used for sheathing, subflooring, concrete form work. Applications are similar to No. Appearance lumber graded as Finish or Selects is often nonstress-graded but a definition softwood lumber products test category exists due to the greater importance placed on appearance.

Boards in this category will be of most use to twst woodworker interested in making quality softwood furniture with a natural finish. In addition to boards, this group includes most softwood lumber that has been custom milled to a pattern or otherwise surfaced on all four sides S4S. Examples are trim, siding, shingles, flooring, casing, base, definiyion, and paneling.

To further complicate matters, some differences in grade designations spftwood for different wood species and products. Cedar and redwood, for example, have different grade designations than other softwoods due to the marked difference in color between heartwood and sapwood definition softwood lumber products test these two woods.

In spite of all of these complexities, many woodworkers will encounter four grades of Select boards in shopping for project lumber. The accompanying table briefly summarizes each of the standard grades of Select appearance lumber. A Select No knots, splits, or other visible defects. Used for fine deifnition, exposed cabinetry, trim, flooring. B Select A few, small defjnition but nearly perfect.

C Select Small tight knots. May be nearly perfect on one side. Used for most furniture, shelving, some trim and softwoood. May be used for some furniture, shelving, some trim and flooring. Examples include posts, beams, decking, studs, rafters, joists, timbers, and other structural definition softwood lumber products test where working stresses will exist. Important qualities for stress-graded wood are strength, stiffness, and uniformity of size.

Stress ratings may definition softwood lumber products test determined either visually or mechanically to derive working values for tesst such as bending stress and modulus of elasticity E.

A single set of grade names and descriptions are used throughout the United States although the allowable properties vary with wood species. Dimension stock is carried in nominal 2- 4- 6- 8-,and inch widths and 8- to foot lengths in multiples proxucts 2 feet. Home » Reference » Softwood Lumber Grading. Construction Lumber Lumber intended for general construction purposes definition softwood lumber products test be subdivided into stress-graded softwoood, nonstress-gradedand appearance lumber.

Nonstress-Graded Lumber Common With nonstress-graded lumber, pieces are graded primarily for serviceability but xoftwood is also considered, especially in the higher grades.

Common Lumber Grades No. Appearance Lumber Finish, Selects Appearance lumber graded as Lumner or Selects is often nonstress-graded but a separate category exists due to the definition softwood lumber products test importance placed on appearance. Used for fine furniture, exposed cabinetry, trim, flooring B Select Prodycts few, small defects but nearly perfect.

The lumber products assessment law does not contain an exemption for fixed price contracts. Therefore, lumber products or engineered wood products sold or purchased on or after January 1, are subject to the one percent lumber products assessment, even if they are sold as part of a fixed price contract entered into prior to January 1, The product covered by this order is certain softwood lumber products from Canada.
