B. Uniform Regulation for the Method of Sale of Commodities

as adopted by

The National Conference on Weights and Measures*

1. Background 

The National Conference on Weights and Measures (NCWM) has long been concerned with the proper units of 

measurement to be used in the sale of all commodities. This approach has gradually broadened to concerns of 

standardized package sizes and general identity of particular commodities. Requirements for individual products 

were at one time made a part of the Weights and Measures Law or were embodied in separate individual Model 

Regulations. In 1971, this “Model State Method of Sale of Commodities Regulation” was established (renamed in 

1983); amendments have been adopted by the Conference almost annually since that time.

Sections with “added 1971” dates refer to those sections that were originally incorporated in the Weights and 

Measures Law or in individual Model Regulations recommended by the NCWM. Subsequent dates reflect the 

actual amendment or addition dates.

The 1979 edition included for the first time requirements for items packaged in quantities of the International 

System of Units (SI), the modernized metric system, as well as continuing to present requirements for inch-pound 

quantities. It should be stressed that nothing in this Regulation requires changing to the SI system of measurement. 

SI values are given for the guidance of those wishing to adopt new SI quantities of the commodities governed by 

this Regulation. SI means the International System of Units as established in 1960 by the General Conference on 

Weights and Measures and interpreted or modified for the United States by the Secretary of Commerce.

This Regulation assimilates all of the actions periodically taken by the Conference with respect to certain food 

items, non-food items, and general method of sale concepts. Its format is such that it will permit the addition of 

individual items at the end of appropriate sections as the need arises. Its adoption as a regulation by individual 

jurisdictions will eliminate the necessity for legislative consideration of changes in the method of sale of particular 

commodities. Such items will be able to be handled through the normal regulation-making process.

2. Status of Promulgation 

The table beginning on page 10 shows the status of adoption of the Uniform Regulation for the Method of Sale of 

Commodities.

*The National Conference on Weights and Measures (NCWM) is supported by the National Institute of Standards 

and Technology (NIST) in partial implementation of its statutory responsibility for “cooperation with the states in 

securing uniformity in weights and measures laws and methods of inspection.”

2.12. H ardwood Lumber - Retail Sales. – The requirements of this section apply to retail sales of hardwood 

lumber, but not to hardwood flooring, molding, or other pre-formed products.

2.12.1. Definitions.

2.12.1.1. Board foot. – The inch-pound unit of volume measurement for hardwood lumber. A board foot 

is the volume of a board 1 ft long, 1 ft wide, and 1 in thick or its equivalent (144 in3 of wood).

2.12.1.2. Surfaced lumber. – Lumber that has been surfaced for the purpose of attaining smoothness of 

surface and uniformity of size.

2.12.1.3. Kiln drying. – A specialized process used to minimize dimensional changes in service. 

Hardwood lumber used for most products must have moisture removed by placing it in a drying kiln with 

controlled humidity and heat for a period of time determined by the initial and the final moisture content, 

the species, and the thickness.

2.12.1.4. Surface measure. – A rounded area measurement for hardwood lumber. The surface measure 

shall be determined by multiplying the full width of the piece in inches and fractions by the standard length 

(see Section 2.12.1.7. Standard Lengths) in feet, dividing by 12, and rounding up or down to the nearest 

whole square foot. (Fractions less than or equal to one-half square foot are rounded down and those greater 

than one-half square foot are rounded up.)

2.12.1.5. Species. – The commercial name assigned to a species of trees.

2.12.1.6. S pecies group. – The commercial name assigned to two or more individual species having 

similar characteristics.

2.12.1.7. Standard lengths. – 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, or 16 feet. Fractional lengths are 

rounded down to the next lower standard length (for example, if a board is 6 ft 8 in long, its length is 

rounded down to 6 ft).

2.12.1.8. Stock widths. – Special items manufactured to predetermined widths, normally for retail sale.

2.12.2. Identity. – Representations shall include a declaration of identity that specifies the species or species 

group.

2.12.3. Surfaced (S4S) Lumber Manufactured to Stock Widths. 

2.12.3.1. Quantity. – Representations shall be in terms of one of the following:

(a) by linear measure when surfaced width and thickness are stated; or

(b) by count when length and surfaced width and thickness are stated; or

(c) by surface measure (square feet) when a thickness is stated.

2.12.3.2. Representations. – The use of nominal dimensions shall be allowed if the table of Minimum 

Surfaced Sizes for Kiln Dried Hardwood Lumber or the actual dimensions are prominently displayed to the 

customer, and the term “nominal” or “nom” is used in conjunction with any representation of nominal 

dimensions.

2.12.3.3 Minimum surfaced sizes for kiln dried lumber (width and thickness). – Table 2. Minimum 

Surfaced Sizes for Kiln Dried Hardwood Lumber, shows the minimum sizes for the stock widths listed. 

This table includes dimensions for thicknesses of 1 in and 2 in thick stock lumber. Hardwood lumber is 

also manufactured in thicknesses of 11⁄4 in (1 in surfaced) and 11⁄2 in (13

/16 in surfaced). For other 

thicknesses, use the nominal and minimum widths from the table. For example: a board with the nominal 

dimensions of 11⁄4 in x 4 in would have minimum thickness of 1 in and minimum width of 31⁄2 in.

The dry thickness of nominal 11⁄2 in lumber is 13/16 in. The dry thickness of nominal 11⁄4 in lumber is 1 in. Sizes are 

shown in inches and millimeters. Minimum sizes in millimeters are calculated by multiplying the size in inches by 

25.4 and rounding to the nearest millimeter. The rule for rounding is: round up for numbers greater than 0.50 mm 

and round down for numbers less than or equal to 0.50 mm. In case of a dispute on size measurements, the inch 

measurement takes precedence. Nominal and minimum widths for these thicknesses are shown above. The SI 

equivalents for 1 in and 13

/16 in lumber are 25.4 mm and 30.1 mm, respectively.

2.12.4. Random Width Lumber. 

2.12.4.1. Sales of random width hardwood lumber. – Sales of random width hardware lumber measured 

after kiln drying shall be quoted, invoiced, and delivered on the basis of net board footage with no addition 

of footage for kiln drying shrinkage or surfacing. Sales of hardwood lumber measured and sold prior to 

kiln drying or surfacing shall be quoted, invoiced, and delivered on the basis of net board footage before 

kiln drying or surfacing. If the lumber is to be kiln dried or surfaced at the request of the purchaser, the 

kiln drying or surfacing charge shall be clearly shown and identified on the quotation and invoice.
