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 U.S. 

customary 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.

The Conference recognized that some states may only adopt the Method of Sale of Commodities Regulation but 

have the legal authority in their weights and measures law to also regulate and take enforcement action in the areas 

of fuels and related products. For this reason, the user will find fuels and related products within this regulation. A 

brief summary related to the development of regulations on these products can be found in the Background 

information of the Uniform Fuels and Automotive Lubricants Regulation. Efforts have been made when practical to 

align both regulations.

(Amended 2021) 

2. Status of Promulgation

The table beginning on page 6 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.”

B. Uniform Regulation for the Method of Sale of Commodities

Preamble

The purpose of this regulation is to require accurate and adequate information about commodities so that purchasers 

can make price and quantity comparisons.

Packages and their labels should enable consumers to obtain accurate information as to the quantity of the contents 

and should facilitate value comparisons. Equally, sales of commodities from bulk should be according to methods 

and units readily recognized and understood by, both, buyer and seller. 

(Added 1989) (Amended 2019) 

Section 1. Food Products [see Section 1. NOTE 1]

Unless otherwise specified or specifically permitted, the sale of any food product, whether sold from bulk or in 

packaged form, shall be only according to a unit of measure or weight that meets all of the following criteria:

(1) Is recognized and defined by NIST as legal for use in commerce

(2) Has been published in the “Federal Register”; and

(3) The measurement values have metrological traceability (see Section 1. NOTE 2) to a national standard

NOTE: Sale of a product or commodity according to count, where appropriate to be fully informative to facilitate 

value comparison, is permissible as a method of sale.

(Added 2019) 

1.1. Berries and Small Fruits

1.1.1. Definitions. – “Small fruits” includes, but is not limited to cherries, currants, and cherry tomatoes. 

“Berries” includes all fruit whose names end in the term “berry.”

(Added 1991)

Section 1. NOTE 1: Packages subject to this Section and the Federal Fair Packaging and Labeling Act shall be 

labeled in units of the International System of Units (SI) and U.S. customary systems of measure effective 

February 14, 1994, [except for seed (see Section 10.10. Packaged Seed) and camera film and recording tape (see 

Section 11.22. Camera Film, Video Recording Tape, Audio Recording Tape, and Other Image and Audio Recording 

Media Intended for Retail Sale and Consumer Use), and as specified in the Uniform Packaging and Labeling 

Regulation under Section 11.32. SI Units, Exemptions - Consumer Commodities]. SI units may appear first.

(Added 1982) (Amended 1990 and 1993)

Section 1. NOTE 2: As defined in NIST Handbook 130, Uniform Weights and Measures Law, Metrological 

traceability means the property of a measurement result whereby the result can be related to a reference through a 

documented unbroken chain of calibrations, each contributing to the measurement uncertainty.

(Added 2019)

1.1.2. Methods of Sale. – Berries and small fruits shall be offered and exposed for sale and sold by weight [see 

Section 1.1.2. NOTE] or by volume. If sold by volume, they must:

(Amended 1991)

(a) be in measure containers that are either open or else covered by uncolored transparent lids or other 

wrappings that do not obscure the contents, and
IV. Uniform Regulations Handbook 130 – 2024 

B. Uniform Regulation for the Method of Sale of Commodities

108

(b) have capacities per Section 1.1.2.(b)(1) or Section 1.1.2.(b)(2). When selling berries and small fruits 

by volume in measure containers, whether or not covered, the measure containers themselves shall not 

be packages for labeling purposes.

(1) SI Capacities – 250 milliliters, 500 milliliters, or 1 liter.

(Added 1979) (Amended 1985)

(2) U.S. Customary Capacities – 1/2 dry pint, 1 dry pint, or 1 dry quart.

Section 1.1.2. NOTE: When used in this regulation, the term “weight” means “mass.” (See paragraphs K. “Mass” 

and “Weight” in Section I. Introduction of NIST Handbook 130 for an explanation of these terms.)

1.1.3. Marking Requirements for Shipping Containers. – If two or more measure containers are placed in a 

shipping package, the crate or package shall show the number of measure containers and the quantity of 

contents of each.

(Added 1971) (Amended 1979, 1985, 1989, and 1991)

1.2. Bread. – Bread kept, offered, or exposed for sale, whether or not packaged or sliced, shall be sold by weight. 

The wrappers of bread that is sold and expressly represented at the time of sale as “stale bread” shall not be 

considered packages for labeling purposes.

(Added 1971) (Amended 1979, 1980, 1985, 1987, 1991, and 1992)

1.3. Butter, Oleomargarine, Margarine, Butter-Like, and/or Margarine-Like Spreads. – Shall be offered and 

exposed for sale and sold by weight. “Butter-like and/or margarine-like spreads” are those products that meet the 

Federal Standard of Identity for butter or margarine and oleomargarine, except that they contain less than 80 % fat 

and may contain other safe and suitable ingredients.

(Added 1971) (Amended 1979, 1985, 1986, and 1994)

1.4. Flour, Corn Meal, and Hominy Grits. – Wheat flour, whole wheat flour, graham flour, self-rising wheat 

flour, phosphated wheat flour, bromated flour, corn flour, corn meal, and hominy grits, whether enriched or not, 

shall be packaged, kept, offered, or exposed for sale and sold by weight.

(Amended 1994)

1.5. Meat, Poultry, Fish, and Seafood. [see Section 1.5. NOTE]

 – Shall be sold by weight, except that whole shellfish in 

the shell may be sold by weight, measure, and/or count. Shellfish are aquatic animals having a shell, such as 

mollusks (for example, scallops) or crustaceans (for example, lobster or shrimp).

(a) When meat, poultry, fish, or seafood is kept, offered or exposed for sale from bulk (e.g., direct service 

counters) by the portion or piece according to a pre-determined fixed weight, the product identity and net 

weight shall be displayed, as well as the unit price at which it is offered for sale. This information shall 

appear on a label or sign immediately adjacent to the meat, poultry, fish, or seafood and must be presented 

in an easy-to-read type style and color. The font size of the net weight and unit price declaration shall be 

equal to or greater than the font size used for the product identity. 

(b) The unit price required under Sections 1.5.(a) shall be in terms of the unit price per kilogram or unit price

per pound and not in common or decimal fractions of the permitted units. A supplemental declaration of a

(other than products in the tables) remanufactured or joined so as to have changed the form or identity, such as 

individually assembled or packaged millwork items. “Nominal sizes” are customary dimensions to describe 

approximate, rather than actual, sizes of lumber. “Nominal sizes” were originally derived from the dimensions of 

rough lumber before surfacing and are always greater than the actual or minimum dressed dimensions; thus, a dry “2

× 4” is surfaced to the actual dimensions of 1 1/2 in × 3 1/2 in (38 mm × 89 mm). The requirements in Section

2.10.1. Definitions refer to actual sizes of lumber. Examples of nominal sizes and minimum dressed sizes for board

The dry thickness of nominal 1 1/2 in lumber is 1 3/16 in. The dry thickness of nominal 1 1/4 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.
