A. Uniform Packaging and Labeling Regulation

as adopted by

The National Conference on Weights and Measures*

18B1. Background

The Uniform Packaging and Labeling Regulation was first adopted during the 37th Annual Meeting of the National 

Conference on Weights and Measures (NCWM) in 1952. Reporting to the Conference, the Committee on Legislation 

stated:

The National Conference should adopt a model package regulation for the guidance of those states authorized to adopt 

such a regulation under provisions of their weights and measures laws. Since so much of the work of weights and 

measures officials in the package field concerns food products, the importance of uniformity between the Federal 

(FDA) regulations and any model regulations to be adopted by this Conference cannot be overemphasized.

Since its inception, the Uniform Packaging and Labeling Regulation has been continually revised to meet the 

complexities of an enormous expansion in the packaging industry – an expansion that, in late 1966, brought about the 

passage of the Fair Packaging and Labeling Act (FPLA). Recognizing the need for compatibility with the Federal 

Act, in 1968 the Committee on Laws and Regulations of the 53rd Annual Meeting of the National Conference amended 

the “Model Packaging and Labeling Regulation” (renamed in 1983) to parallel regulations adopted by federal agencies 

under FPLA. The process of amending and revising this Regulation is a continuing one in order to keep it current 

with practices in the packaging field and make it compatible with appropriate federal regulations. Amendments and 

additions since 1971 are noted at the end of each section.

The revision of 1978 provided for the use of the metric system (SI) on labels as well as allowing SI-only labels for 

those commodities not covered by federal laws or regulations. “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. [See the “Interpretation of the International System of Units for the United 

States” in the “Federal Register” (Volume 73, No. 96, pages 28432 to 28433) for May 16, 2008, and 15 United States 

Code, Section 205a - 205l “Metric Conversion.” See also NIST Special Publication 330 “The International System 

of Units (SI)” 2008 edition and NIST Special Publication 811 “Guide for the Use of the International System of Units 

(SI)” 2008 edition that are available at www.nist.gov/pml/weights-and-measures/publications/metricpublications or by contacting TheSI@nist.gov.] In 1988, Congress amended the Metric Conversion Law to declare 

that it is the policy of the United States to designate the International System of Units of measurement as the preferred 

system of weights and measures for U.S. trade and commerce. In 1992, Congress amended the federal FPLA to 

require the most appropriate units of the SI and the U.S. customary systems of measurement on certain consumer 

commodities. The 1993 amendments to NIST Handbook 130 require SI and U.S. customary units on certain consumer 

commodities in accordance with federal laws or regulations. Requirements for labeling in both units of measure were 

effective February 14, 1994, under FPLA and as specified in Section 15. Effective Date; except as specified in 

Section 11.32. SI Units, Exemptions for Consumer Commodities.

In 2015, the Federal Trade Commission (FTC) conducted a periodic review of its regulations issued under the FPLA 

and recently published several revisions which go into effect on December 17, 2015. [See the “Rules, Regulations, 

Statements of General Policy or Interpretation and Exemptions Under the Fair Packaging and Labeling Act] Final 

Rule” in the “Federal Register” (Volume 80, No. 221, pages 71686 to 71689) dated Tuesday, November 17, 2015. In 

response to comments from the NCWM’s Packaging and Labeling Subcommittee, the FTC amended its regulations 

to clarify that exponents may be used in conjunction with U.S. customary units and recognized that with today’s online 

resources the location of a business can be readily obtained in lieu of using a printed telephone directory. The FTC 

amended its regulations on the Declaration of Responsibility to allow the street address to be omitted if it is accessible 

in a printed or online telephone directory, or any readily accessible, widely published and publicly available resource. 

In response to a concern that the existing regulation included a limited table of metric conversions, the FTC decided 

to incorporate the more comprehensive metric conversion tables to provide users with the wide range of factors in 

NIST Handbook 133 (2015) “Checking the Net Contents of Packaged Goods,” Appendix E, General Tables of Units 

of Measurements. The FTC also revoked regulations on certain retail price sale representations, since they are no

52

longer used in the marketplace. The regulation was also amended to aid state and local compliance efforts by alerting 

users of the role of the states in regulating packages that fall outside the scope of the FTC’s purview under the FPLA.

(Added 2016)

Nothing contained in this regulation should be construed to supersede any labeling requirement specified in federal 

law or to require the use of SI units on non-consumer packages.

19B2. Status of Promulgation

The table beginning on page 6, Section II. Uniformity of Laws and Regulations of Handbook 130 shows the status of 

adoption of the Uniform Packaging and Labeling Regulation.

*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.”

A. Uniform Packaging and Labeling Regulation

Preamble

The purpose of this regulation is to provide accurate and adequate information on packages as to the identity and 

quantity of contents so that purchasers can make price and quantity comparisons.

(Added 1989)

Section 1. Application 

This regulation shall apply to packages, but shall not apply to:

(a) inner wrappings not intended to be individually sold to the customer;

(b) shipping containers or wrapping used solely for the transportation of any commodities in bulk or in quantity

to manufacturers, packers, or processors, or to wholesale or retail distributors, but in no event shall this

exclusion apply to packages of consumer or non-consumer commodities as defined herein;

(Added 1971)

(c) auxiliary containers or outer wrappings used to deliver packages of such commodities to retail customers if

such containers or wrappings bear no printed matter pertaining to any particular commodity;

(d) containers used for retail tray pack displays when the container itself is not intended to be sold (e.g., the tray

that is used to display individual envelopes of seasonings, gravies, etc., and the tray itself is not intended to

be sold);

(e) open carriers and transparent wrappers or carriers for containers when the wrappers or carriers do not bear

any written, printed, or graphic matter obscuring the label information required by this regulation; or

(f) packages intended for export to foreign countries.

(Amended 1994 and 1998)

Section 2. Definitions 

2.1. Package. – Except as modified by Section 1. Application, the term “package,” whether standard package or 

random package, means any commodity:

(a) enclosed in a container or wrapped in any manner in advance of wholesale or retail sale; or

(b) whose weight [NOTE 1, page 57] or measure has been determined in advance of wholesale or retail sale. An

individual item or lot of any commodity on which there is marked a selling price based on an established

price per unit of weight or of measure shall be considered a package or packages.

(Amended 1988 and 1991)

NOTE 1: When used in this law (or regulation), the term “weight” means “mass.” (See paragraphs K. “Mass” and 

“Weight” and L. Use of the Terms “Mass” and “Weight” in Section I. Introduction of NIST Handbook 130 for an 

explanation of these terms.)

(Note added 1993)

2.2. Consumer Package of Consumer Commodity. – A package that is customarily produced or distributed for 

sale through retail sales agencies or instrumentalities for consumption or use by individuals for the purposes of 
IV. Uniform Regulations Handbook 130 – 2018

A. Uniform Packaging and Labeling Regulation

58

personal care or in the performance of services ordinarily rendered in or about the household or in connection with 

personal possessions.

(Amended 1988 and 1991)

2.3. Non-Consumer Package: Package of Non-Consumer Commodity. – Any package other than a consumer 

package, and particularly a package intended solely for industrial or institutional use or for wholesale distribution.

(Amended 1988 and 1991)

2.4. Random Package. – A package that is one of a lot, shipment, or delivery of packages of the same consumer 

commodity with no fixed pattern of net contents.

(Amended 1988 and 1990)

2.5. Label. – Any written, printed, or graphic matter affixed to, applied to, attached to, blown into, formed, molded 

into, embossed on, or appearing upon or adjacent to a consumer commodity, or a package containing any consumer 

commodity, for purposes of branding, identifying, or giving any information with respect to the commodity or to the 

contents of the package, except that an inspector’s tag or other non-promotional matter affixed to or appearing upon 

a consumer commodity shall not be considered a label requiring the repetition of label information required by this 

regulation.

(Amended 1988)

2.6. Person. – The term “person” means either singular or plural and shall include any individual, partnership, 

company, corporation, association, or society.

(Amended 1988)

2.7. Principal Display Panel or Panels. – That part, or those parts, of a label that is, or are, so designed as to most 

likely be displayed, presented, shown, or examined under normal and customary conditions of display and purchase. 

Wherever a principal display panel appears more than once on a package, all requirements pertaining to the “principal 

display panel” shall pertain to all such “principal display panels.”

(Amended 1988)

2.8. Multi-unit Package. – A package containing two or more individual packages of the same commodity, in the 

same quantity, intended to be sold as a multi-unit package, but where the component packages are labeled individually 

in full compliance with all requirements of this regulation.

(Amended 1988)

2.9. Combination Package. – A package intended for retail sale, containing two or more individual packages or units 

of dissimilar commodities.

Examples: 

antiquing or housecleaning kit

sponge and cleaner

lighter fluid and flints

(Added 1989)

2.10. Variety Package. – A package intended for retail sale, containing two or more individual packages or units of 

similar, but not identical, commodities. Commodities that are generically the same, but that differ in weight, measure, 

volume, appearance, or quality, are considered similar, but not identical.

Examples: 

two sponges of different sizes

plastic tableware, consisting of 4 spoons, 4 knives, and 4 forks

(Added 1989)

59

2.11. Petroleum Products. – Gasoline, diesel fuel, kerosene, or any product (whether or not such a product is actually 

derived from naturally occurring hydrocarbon mixtures known as “petroleum”) commonly used in powering, 

lubricating, or idling engines or other devices, or is labeled as fuel to 

power camping stoves or lights. Therefore, sewing machine lubricant, 

camping fuels, and synthetic motor oil are “petroleum products” for the 

purposes of this regulation. Brake fluid, copier machine dispersant, 

antifreeze, cleaning solvents, and alcohol are not “petroleum 

products.”

(Added 1987) (Amended 1988)

2.12. Spot Label. – A spot label is a label clearly defined by means of 

a border, indentation, or other means that covers only a small portion 

of the surface of a principal display panel of a package; the entire 

portion of the principal display panel outside the area of the label 

contains no printed or graphic matter of any kind. A spot label may 

contain all required labeling information (identity, responsibility, and net contents), but it must at least indicate the 

identity and net contents. See Section 11.29. Spot Label for net contents placement exemption for a spot label.

(Added 1990) (Amended 1991)

2.13. Header Strip. – A header label or header strip is a label that is attached across the top of a transparent or opaque 

bag or other container that bears no other printed or graphic material. See Section 11.30. Header Strip for net contents 

placement exemptions.

(Added 1990)

2.14. Standard Package. – A package that is one of a lot, shipment, 

or delivery of packages of the same commodity with identical net 

contents declarations.

Examples: 

1 L bottles or 12 fl oz cans of carbonated soda

500 g or 5 lb bags of sugar

100 m packages of rope

(Added 1991)

2.15. SI or SI Units. – SI or SI Units 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. 

See the “Interpretation of the International System of Units for the United States” in the “Federal Register” 

(Volume 73, No. 96, pages 28432 to 28433) for May 16, 2008, and 15 United States Code, Section 205a - 2051 

“Metric Conversion.” See also NIST Special Publication 330, The International System of Units (SI), 2008 edition

and NIST Special Publication 811, Guide for the Use of the International System of Units (SI), 2008 edition that are 

available at www.nist.gov/pml/weights-and-measures/publications/metric-publications or by contacting

TheSI@nist.gov. 

(Added 1993)

Section 3. Declaration of Identity: Consumer Package

3.1. Declaration of Identity: Consumer Package. – A separate declaration of identity [NOTE 2, page 60] on a consumer 

package shall appear on the principal display panel and shall not be misleading or deceptive. The identity shall be in 

terms of:

(a) the name specified in or required by any applicable federal or state law or regulation or, in the absence of

this;

(b) the common or usual name or, in the absence of this;

(c) the generic name or other appropriate description, including a statement of function (such as “cleaning

powder”).

(Amended 1990) (Note added 1986)

NOTE 2: Section 19.(a) of the Uniform Weights and Measures Law (and 21 CFR 101.100 (b) (3) for non-meat and 

non-poultry foods) specifically exempts food packages from identity statements if the commodity is a food, other than 

meat or poultry, that was repackaged in a retail establishment and the food is displayed to the purchaser under either 

of the following circumstances: “(1) its interstate labeling is clearly in view or with a counter card, sign, or other 

appropriate device bearing prominently and conspicuously the common or usual name of the food, or (2) the common 

or usual name of the food is clearly revealed by its appearance.”

(Added 1986) (Amended 2001)

3.1.1. Parallel Identity Declaration: Consumer Package. – A declaration of the identity on a consumer 

package shall appear generally parallel to the base on which the package rests as it is designed to be displayed.

Section 4. Declaration of Identity: Non-Consumer Package

A declaration of identity [NOTE 2, page 60] on a non-consumer package shall appear on the outside of a package and shall 

not be misleading or deceptive. The identity shall be in terms of:

(a) the name specified in or required by any applicable federal or state law or regulation or, in the absence of

this;

(b) the common or usual name or, in the absence of this;

(c) the generic name or other appropriate description, including a statement of function (such as “cleaning

powder”).

(Amended 1990) (Note added 1986)

Section 5. Declaration of Responsibility: Consumer and Non-Consumer Packages

Any package kept, offered, or exposed for sale, or sold at any place other than on the premises where packed shall 

specify conspicuously on the label of the package the name and address of the manufacturer, packer, or distributor. 

The name shall be the actual corporate name, or, when not incorporated, the name under which the business is 

conducted. The address shall include street address, city, state (or country if outside the United States), and ZIP Code 

(or the mailing code, if any, used in countries other than the United States); however, the street address may be omitted 

if it is listed in any readily accessible, well-known, widely published, and publicly available resource, including but 

not limited to a printed directory, electronic database, or website. 

(Amendment effective December 17, 2015)

If a person manufactures, packs, or distributes a commodity at a place other than his principal place of business, the 

label may state the principal place of business in lieu of the actual place where the commodity was manufactured or 

packed or is to be distributed, unless such statement would be misleading. Where the commodity is not manufactured 

by the person whose name appears on the label, the name shall be qualified by a phrase that reveals the connection

may appear first.

(Added 1982) (Amended 1990 and 1993)

6.2. Largest Whole Unit. – Where this regulation requires that the quantity declaration be in terms of the largest 

whole unit, the declaration shall, with respect to a particular package, be in terms of the largest whole unit of weight 

or measure with any remainder expressed (following the requirements of Section 6.5.2. (a) Fractions and Section 6.11. 

Fractions):

(a) SI Units. – in decimal fractions of such largest whole unit.

(b) U.S. Customary Units.

other material packed with such commodity (except as noted in Section 10.3. Aerosols and Other Pre-pressurized 

Containers Dispensing Product Under Pressure), shall appear on the principal display panel of a consumer package 

and, unless otherwise specified in this regulation (see Sections 6.6. Prescribed Units, SI, through 6.9. Bi-dimensional 

Commodities), shall be in terms of the largest whole unit.

6.3.1. Use of “Net Mass” or “Net Weight.” – A quantity declaration may stand alone [e.g., “200 g (7 oz)” or 

“1 lb (453 g)”] or may include the term “net mass” or “net weight” either preceding or following the declaration. 

The term “net” by itself may be used on food labels. However, the quantity of contents shall always declare the 

net quantity of contents even when such terms are not used.

(Amended 1993)

6.3.2. Lines of Print or Type. – A declaration of quantity may appear on one or more lines of print or type.

commodity shall be expressed in terms of:

(a) solid, semisolid, viscous, or a mixture of solid

and liquid

weight or mass

(b) liquid fluid volume measure

(c) dry dry measure

(d) or labeled by linear measure or area linear measure or area

(e) or labeled by numerical units (count) numerical count

However, if there exists a firmly established general consumer usage and trade custom with respect to the terms used 

in expressing a declaration of quantity of a particular commodity, such a declaration of quantity may be expressed in 

its traditional terms, provided such traditional declaration gives accurate and adequate information as to the quantity 

of the commodity. Any net content statement that does not permit price and quantity comparisons is forbidden.

(Amended 1989 and 2015)

6.4.1. Combination Declaration. 

(a) A declaration of quantity in terms of weight or volume shall be combined with appropriate declarations

of the measure, count, and size of the individual units unless a declaration of weight alone is fully

informative.

(b) A declaration of quantity in terms of measure shall be combined with appropriate declarations of the

weight, volume, count, and size of the individual units unless a declaration of measure alone is fully

informative.

(c) A declaration of quantity in terms of count shall be combined with appropriate declarations of the weight,

volume, measure, and size of the individual units unless a declaration of count alone is fully informative.

Table 6.5.

SI Units: Mass, Measure

If a declaration of quantity is in units of: The units shall be in:

(a) mass kilogram, gram, or milligram

(b) liquid measure liter or milliliter and shall express the volume at 

20 °C, except for:

(1) petroleum products or distilled spirits for

which the declaration shall express the

volume at 15.6 °C;

(2) a commodity that is normally sold and

consumed while frozen for which the

declaration shall express the volume at the

frozen temperature; and

(3) malt beverages or a commodity that must be

maintained in the refrigerated state for which

the declaration shall express the volume at

4 °C.

(c) linear measure meter, centimeter, or millimeter

(d) area measure square meter, square decimeter, square centimeter, 

or square millimeter

(e) volume other than liquid measure liter or milliliter, except that units cubic meter and 

cubic centimeter shall be used only when 

specifically designated as a method of sale

(f) Rule of 1000. – The selected multiple or submultiple prefixes for SI units shall result in numerical values

between 1 and 1000. This rule allows centimeters or millimeters to be used where a length declaration is less

than 100 centimeters.

Examples:

500 g, not 0.5 kg

1.96 kg, not 1960 g

750 mL, not 0.75 L

750 mm or 75 cm, not 0.75 m

(Added 1993)

(g) SI declarations should be shown in three digits except where the quantity is below 100 grams, milliliters,

centimeters, square centimeters, or cubic centimeters, where it may be shown in two digits. In either case,

any final zero appearing to the right of the decimal point need not be shown; and

(Added 1993)

(h) the declaration of net quantity of contents shall not be expressed in mixed units.

Example: 

1.5 kg, not 1 kg 500 g

6.5.1. Symbols. – Any of the following symbols for SI units, and none other, may be employed in the quantity

statement on a package of commodity:

centimeter cm cubic meter m3

cubic centimeter cm3 kilogram kg

meter m gram g

milligram mg millimeter mm

liter L or l square meter m2

milliliter mL or ml cubic decimeter dm3

square centimeter cm2 square decimeter dm2

micrometer μm microgram μg or mcg

(a) Symbols [NOTE 4, page 64], except for liter, are not capitalized unless the unit is derived from a proper name.

Periods shall not be used after the symbol. Symbols shall always be written in the singular form. Adding

“s” to an SI symbol to express the plural of the symbol is prohibited.

(b) The “L” symbol and the “mL” symbol are preferred; however, the “l” symbol for liter and “ml” symbol

for milliliter are permitted.

(Amended 1980 and 1993)

NOTE 4: The “e” mark shall not be considered to be a qualifying word or phrase and may be used as part of the 

statement of the net quantity of contents where warranted. When used, the “e” mark shall be at least 3 mm 

(approximately 1⁄8 in) in height. The term “e” mark refers to the symbol “e” used in connection with the quantity 

declarations on labels of some consumer commodities marketed primarily in the European Union (EU) and South 

Africa. The “e” mark constitutes a representation by the packer or importer that the package to which it is applied 

has been filled in accordance with the average system of quantity specified by the EU. The average system is a method 

of declaring package fill in the EU and other countries of the world, including the United States. 

(Added 1993)

6.5.2. Fractions and Prefixes. 

(a) Fractions: An SI statement in a declaration of net quantity of contents of any consumer commodity

may contain only decimal fractions.

(b) Prefixes: The following chart indicates SI prefixes that may be used on a broad range of consumer

commodity labels to form multiples and submultiples of SI units:

Prefix Symbol

Multiplying

Factor*

kilo- k × 103

deka-** da × 10 

deci-** d × 10−1

centi-*** c × 10−2

milli- m × 10−3

micro-**** μ × 10−6

*102 = 100; 103 = 1000; 10−1 = 0.1; 10−2 = 0.01

Thus, 2 kg = 2 × 1000 g = 2000 g and 3 cm = 3 × 0.01 m = 0.03 m

**Not permitted on food labels.

***Should only be used with “meter.”

 Shall only be used for measurements less than 1 mm.

Both upper and lowercase letters and exponents are acceptable.

(Amendment effective December 17, 2017)

(Added 1974) (Amended 1980, 1990, 1993, and 2016)

6.7.2. Units of Two or More Meanings. – When the term “ounce” is employed in a declaration of liquid quantity,

(Amended 1984)

6.8.2. One Foot, 1 Square Foot, 1 Pound, 1 Pint, 1 Gallon, or More. – The declaration of quantity shall be 

expressed in the following terms (see Section 6.2. Largest Whole Unit and Section 6.11. Fractions):

(a) Linear Measure. – If 1 ft or more, expressed in terms of the largest whole unit (a yard or a foot) with

any remainder expressed in inches and fractions of the inch or in fractions of the foot or yard, except that

it shall be optional to include a statement of length in terms of inches.

(b) Area Measure.

(1) If 1 ft2 or more, but less than 4 ft2

, expressed in square feet with any remainder expressed in square

random package may be expressed in decimal fractions of the largest appropriate unit carried out to not 

more than three decimal places.

(Amended 1993)

6.9. Bi-dimensional Commodities. – For bi-dimensional commodities(including roll-type commodities) the quantity 

declaration shall be expressed in both SI and U.S. customary units of measurement as follows:

(a) if the area is less than 929 cm2 (1 ft2

), in terms of length and width (expressed in the largest whole unit for SI

and in linear inches and fractions of linear inches for U.S. customary);

Example: 

20.3 cm × 25.4 cm (8 in × 10 in)

(b) if the area is at least 929 cm2 (1 ft2

), but less than 37.1 dm2 (4 ft2), in terms of area (expressed in the largest

whole unit for SI and in square inches for U.S. customary), followed by a declaration of the length and width

in terms of the largest whole unit:

Example: 

31 dm2 (49 cm × 64 cm) 3.36 ft2 (1.6 ft × 2.1 ft), provided:

(1) bi-dimensional commodities having a width of 10 cm (4 in) or less, the declaration of net quantity shall

be expressed in terms of width and length in linear measure; no declaration of area is required;

(2) an U.S. customary dimension of less than 2 ft may be stated in inches;

(3) commodities consisting of usable individual units (e.g., paper napkins) require a declaration of unit area

but not a declaration of total area of all such units (except roll-type commodities with individual usable

units created by perforations, for which see Section 6.10. Count: Ply); and

(4) U.S. customary declarations may include after the statement of the linear dimensions in the largest whole

unit a parenthetical declaration of the same dimensions in inches.

Example: 

25 ft2 (12 in × 8.33 yd) (12 in × 300 in)

(c) if the area is 37.1 dm2 (4 ft2

) or more, in terms of area (expressed in the largest whole unit for SI and in square

feet for U.S. customary), followed by a declaration of the length and width, in terms of the largest whole unit,

provided:

(1) no declaration of area is required for a bi-dimensional commodity with a width of 10 cm (4 in) or less;

(2) bi-dimensional commodities with a width of 10 cm (4 in) or less, the U.S. customary statement of width

shall be expressed in terms of linear inches and fractions thereof, and length shall be expressed in the

largest whole unit (yard or foot) with any remainder in terms of fractions of the yard or foot, except that

it shall be optional to express the length in the largest whole unit followed by a statement of length in

inches or to express the length in inches followed by a statement of length in the largest whole unit;

Examples: 

5 cm × 9.14 m (2 in × 10 yd)

5 cm × 9.14 m (2 in × 10 yd) (360 in)

5 cm × 9.14 m (2 in × 360 in) (10 yd)

(3) an U.S. customary dimension of less than 2 ft may be stated in inches; and

A. Uniform Packaging and Labeling Regulation

69

(d) no declaration of area is required for commodities for which the length and width measurements are critical

in terms of end use (such as wallpaper border) if such commodities clearly present the length and width

measurements on the label.

6.10. Count: Ply. – If the commodity is in individually usable units of one or more components or plies, the quantity 

declaration shall, in addition to complying with other applicable quantity declaration requirements of this regulation, 

include the number of plies and total number of usable units.

Roll type commodities, when perforated so as to identify individual usable units, shall not be deemed to be made up 

of usable units; however, such roll type commodities shall be labeled in terms of:

(a) total area measurement;

(b) number of plies;

(c) count of usable units; and

(d) dimensions of a single usable unit.

(Amended 1988)

6.11. Fractions.

(a) U.S. Customary: An U.S. customary unit statement of net quantity of contents of any consumer commodity

may contain common or decimal fractions. A common fraction shall be in terms of halves, quarters, eighths,

sixteenths, or thirty-seconds, except that:

(1) if there exists a firmly established general consumer usage and trade custom of employing different

common fractions in the net quantity declaration of a particular commodity, they may be employed; and

(2) if linear measurements are required in terms of yards or feet, common fractions may be in terms of thirds.

(b) Common fractions: A common fraction shall be reduced to its lowest term.

Example: 2

/4 becomes 1⁄2

(c) Decimal fractions: A decimal fraction shall not be carried out to more than three places.

(Amended 1986 and 1993)

6.12. Supplementary Quantity Declarations. – The required quantity declaration may be supplemented by one or 

more declarations of weight, measure, or count, such declaration appearing other than on a principal display panel. 

Such supplemental statement of quantity of contents shall not include any term qualifying a unit of weight, measure, 

or count that tends to exaggerate the amount of commodity contained in the package (e.g., “giant” quart, “larger” liter, 

“full” gallon, “when packed,” “minimum,” or words of similar import).

6.13. Rounding. [NOTE 5, page 70] – In all conversions for the purpose of showing an equivalent SI or U.S. customary 

quantity to a rounded U.S. customary or SI quantity, or in calculated values to be declared in the net quantity statement, 

the number of significant digits retained must be such that accuracy is neither sacrificed nor exaggerated. Conversions, 

the proper use of significant digits, and rounding must be based on the packer’s knowledge of the accuracy of the 

original measurement that is being converted. In no case shall rounded net contents declarations overstate a quantity; 

the packer may round the converted values down to avoid overstating the net contents.

(Amended 1993)
IV. Uniform Regulations Handbook 130 – 2018

A. Uniform Packaging and Labeling Regulation

70

NOTE 5: When as a result of rounding SI or U.S. customary declarations the resulting declarations are not exact, 

the largest declaration (either metric or U.S. customary) will be used for enforcement purposes to determine whether 

a package contains at least the declared amount of the product.

6.14. Qualification of Declaration Prohibited. – In no case shall any declaration of quantity be qualified by the 

addition of the words “when packed,” “minimum,” or “not less than” or any words of similar import (e.g., 

“approximately”), nor shall any unit of weight, measure, or count be qualified by any term (such as “jumbo,” “giant,” 

“full,” or the like) that tends to exaggerate the amount of commodity. 

(Amended 1998)

6.15. Character of Declaration: Average. – The average quantity of contents in the packages of a particular lot, 

shipment, or delivery shall at least equal the declared quantity, and no unreasonable shortage in any package shall be 

permitted even though overages in other packages in the same shipment, delivery, or lot compensate for such shortage.

(Added 1981)

6.16. Random Packages. – A random weight package must bear a label conspicuously declaring:

(a) the net weight;

(b) unit price; and

(c) the total price.

In the case of a random package packed at one place for subsequent sale at another, neither the price per unit of weight 

nor the total selling price need appear on the package, provided the package label includes both such prices at the time 

it is offered or exposed for sale at retail.

(Added 1999)

Section 7. Declaration of Quantity: Non-Consumer Packages

7.1. General. – The SI and U.S. customary systems of weights and measures are recognized as proper systems to be 

used in the declaration of quantity. Units of both systems may be combined in a dual declaration of 

quantity. [NOTE 6, page 70] (See Section 6.3. Net Quantity, and Section 6.3.1. Use of “Net Mass” or “Net Weight.”)

NOTE 6: Although non-consumer packages under this Regulation may bear SI declarations only, this Regulation 

should not be construed to supersede any labeling requirement specified in federal law.

7.2. Location. – A non-consumer package shall bear on the outside a declaration of the net quantity of contents. Such 

declaration shall be in terms of the largest whole unit (see Section 6.2. Largest Whole Unit; for small packages, see 

Section 11.16. Small Packages).

7.3. Terms: Weight, Liquid Measure, Dry Measure, or Count. – The declaration of the quantity of a particular 

commodity shall be expressed in terms of liquid measure if the commodity is liquid, in terms of dry measure if the 

commodity is dry, in terms of weight if the commodity is solid, semisolid, viscous, or a mixture of solid and liquid, 

or in terms of numerical count. However, if there exists a firmly established general consumer usage and trade custom 

with respect to the terms used in expressing a declaration of quantity of a particular commodity, such declaration of 

quantity may be expressed in its traditional terms if such traditional declaration gives accurate and adequate 

information as to the quantity of the commodity.

7.4. SI Units: Mass, Measure. – A declaration of quantity:

(a) in units of mass shall be in terms of the kilogram, gram, or milligram;

(b) in units of liquid measure shall be in terms of the liter or milliliter, and shall express the volume at 20 °C,

except in the case of petroleum products or distilled spirits, for which the declaration shall express the volume

71

at 15.6 °C, and except also in the case of a commodity that is normally sold and consumed while frozen, for 

which the declaration shall express the volume at the frozen temperature, and except also in the case of malt 

beverages or a commodity that is normally sold in the refrigerated state, for which the declaration shall 

express the volume at 4 °C;

(Amended 1985)

(c) in units of linear measure shall be in terms of the meter, centimeter, or millimeter;

(d) in units of area measure shall be in terms of the square meter, square decimeter, square centimeter or square

millimeter;

(e) in units of volume other than liquid measure shall be in terms of the liter and milliliter, except that the terms

cubic meter, cubic decimeter, and cubic centimeter will be used only when specifically designated as a

method of sale;

(f) Rule of 1000. – The selected multiple or submultiple prefixes for SI units shall result in numerical values

between 1 and 1000. This rule allows centimeters or millimeters to be used where a length declaration is less

than 100 centimeters;

Examples:

500 g, not 0.5 kg

1.96 kg, not 1960 g

750 mL, not 0.75 L

750 mm or 75 cm, not 0.75 m

(Added 1993)

(g) SI declarations should be shown in three digits except where the quantity is below 100 grams, milliliters,

centimeters, square centimeters, or cubic centimeters where it can be shown in two digits. In either case, any

final zero appearing to the right of the decimal point need not be shown; and

(Added 1993)

(h) the declaration of net quantity of contents shall not be expressed in mixed units.

Example: 

1.5 kg, not 1 kg 500 g

7.4.1. Symbols. – Only those symbols as detailed in Section 6.5.1. Symbols, and none other, may be employed 

in the quantity statement on a package of commodity.

7.5. U.S. Customary Units: Weight, Measure. – A declaration of quantity:

(a) in units of weight shall be in terms of the avoirdupois pound or ounce;

(b) in units of liquid measure shall be in terms of the United States gallon of 231 cubic inches or liquid quart,

liquid pint, or fluid ounce subdivisions of the gallon and shall express the volume at 68 °F, except in the case

of petroleum products or distilled spirits, for which the declaration shall express the volume at 60 °F, and

except also in the case of a commodity that is normally sold and consumed while frozen, for which the

employed in the quantity statement on a package of commodity. (For commonly accepted symbols and 

abbreviations, see Section 6.7.1. Symbols and Abbreviations.)

7.6. Character of Declaration: Average. – The average quantity of contents in the packages of a particular lot, 

shipment, or delivery shall at least equal the declared quantity, and no unreasonable shortage in any package shall be 

permitted, even though overages in other packages in the same shipment, delivery, or lot compensate for such shortage.

Section 8. Prominence and Placement: Consumer Packages

8.1. General. – All information required to appear on a consumer package shall appear thereon in the English 

language and shall be prominent, definite, plain, and conspicuous as to size and style of letters and numbers and as to 

color of letters and numbers in contrast to color of background. Any required information that is either in hand 

lettering or hand script shall be entirely clear and equal to printing in legibility.

8.1.1. Location. – The declaration or declarations of quantity of the contents of a package shall appear in the 

bottom 30 % of the principal display panel or panels. For cylindrical containers, see also Section 10.7. Cylindrical 

Containers for additional requirements. For small packages, see Section 11.16. Small Packages.

(Amended 1975)

8.1.2. Style of Type or Lettering. – The declaration or declarations of quantity shall be in such a style of type 

or lettering as to be boldly, clearly, and conspicuously presented with respect to other type, lettering, or graphic 

material on the package, except that a declaration of net quantity blown, formed, or molded on a glass or plastic 

surface is permissible when all label information is blown, formed, or molded on the surface.

8.1.3. Color Contrast. – The declaration or declarations of quantity shall be in a color that contrasts 

conspicuously with its background, except that a declaration of net quantity blown, formed, or molded on a glass 

or plastic surface shall not be required to be presented in a contrasting color if no required label information is on 

the surface in a contrasting color.

8.1.4. Free Area. – The area surrounding the quantity declaration shall be free of printed information:

(a) above and below, by a space equal to at least the height of the lettering in the declaration; and

(b) to the left and right, by a space equal to twice the width of the letter “N” of the style and size of type

used in the declaration.

(b) in the case of a cylindrical or nearly cylindrical container, 40 % of the product of the height of the container

times the circumference;

For Figure 4, the area of the principal display panel is:

25 cm (10 in) × 5 cm (2 in) = 125 cm (20 in2

) × 0.40 = 50 cm2 (8 in2) 

(see also Section 10.7. Cylindrical Containers).

The area of the principal display panel is the same in both examples. The declaration of net quantity of 

contents must be of the same height in both cases. It is not the size of the label that is used to determine the 

minimum type size of the quantity statement, but the size of the surface of the package exposed to view to 

the customer. The package on the right side of the figure has a spot label (see Section 2.12. Spot Label and 

Section 11.29. Spot Label); and

(c) in the case of any other shaped container, 40 % of the total surface of the container, unless such container

presents an obvious principal display panel (e.g., the top of a triangular or circular package of cheese, or the

top of a can of shoe polish), in which event the area shall consist of the entire such surface.

form” (see Section 2.1. Package) of the same commodity shall bear on the outside of the package a declaration of:

(a) the number of individual units;

(b) the quantity of each individual unit; and

(c) the total quantity of the contents of the multi-unit package.

Example:

soap bars, 6 Bars, Net Wt 100 g (3.53 oz) each

total Net Wt 600 g (1.32 lb).

The term “total” or the phrase “total contents” may precede the quantity declaration.

A multi-unit package containing unlabeled individual packages which are not intended for retail sale separate 

from the multi-unit package may contain, in lieu of the requirements of section (a), a declaration of quantity of 

contents expressing the total quantity of the multi-unit package without regard for inner packaging. For such 

multi-unit packages it shall be optional to include a statement of the number of individual packages when such a 

statement is not otherwise required by the regulations.

Examples:

NOTE 7: For foods, a “multi-unit” package means a package containing two or more individually packaged units 

of the identical commodity in the same quantity, intended to be sold as part of the multi-unit package but labeled to 

be individually sold in full compliance with this regulation. Open multi-unit retail food packages under the authority 

of the FDA or the USDA that do not obscure the number of units or prevent examination of the labeling on each of 

the individual units are not required to declare the number of individual units or the total quantity of contents of the 

multi-unit package if the labeling of each individual unit complies with requirements so that it is capable of being sold 

individually. (See also Section 11.11. Soft Drink Bottles and Section 11.12. Multi-Unit Soft-Drink Bottles.)

(Added 1984)

10.5. Combination Packages. – A combination package is a package intended for retail sale, containing two or more 

individual packages or units of dissimilar commodities. The declaration of net quantity for a combination package 

shall contain an expression of weight, volume, measure, or count or a combination thereof, as appropriate, for each 

individual package or unit, provided the quantity statements for identical packages or units shall be combined. This 

section does not apply to food or other commodities subject to the Federal Food, Drug, and Cosmetic Act (21 USC).

UPLR Appendix B: Converting U.S. Customary Units to SI Units

for Quantity Declarations on Packages 

1. Conversion.

To convert an U.S. customary quantity to an SI quantity, multiply the appropriate conversion factor in Table 1 in 

Appendix A by the U.S. customary unit and round according to the following rules.

2. Rounding and Significant Digits.

It is the packager’s responsibility to round converted values appropriately and select the appropriate number of 

significant digits to use in quantity declaration. [These rounding rules are for converting quantity determinations on 

packages and do not apply to digital scales that automatically round indications to the nearest indicated value.] 

Conversions, the proper use of significant digits, and rounding must be based on the packer’s knowledge of the 

accuracy of the original measurement that is being converted. For example, if a package is labeled 453.59 g (1 lb), 

the packer is implying that the package declaration is accurate within ± 0.005 g (or ± 5 mg). For liquid volume 

measure, a label declaration of 473 mL (16 fl oz) implies that the package declaration is accurate to within 

± 0.5 mL (0.01 fl oz). The requirements of 6.13. Rounding apply to all quantity declarations that are derived from 

converted values:

6.13. Rounding. – In all conversions for the purpose of showing an equivalent SI or U.S. customary

quantity to a rounded U.S. customary or SI quantity, or in calculated values to be declared in the net quantity 

statement, the number of significant digits retained must be such that accuracy is neither sacrificed nor 

exaggerated. Conversions, the proper use of significant digits, and rounding must be based on the packer’s 

knowledge of the accuracy of the original measurement that is being converted. In no case shall rounded 

net contents declarations overstate a quantity; the packer may round the converted values down to avoid 

overstating the net contents.

NOTE: When as a result of rounding SI or U.S. customary declarations calculated based on the conversion factors 

in Appendix A, the resulting declarations are not exact, the largest declaration, whether metric or U.S. customary, 

will be used for enforcement purposes to determine whether a package contains at least the declared amount of the 

product.

Do not round conversion factors or any other quantity used or determined in the calculation; only round the final 

quantity to the number of significant digits needed to maintain the accuracy of the original quantity. Use the rounding 

rules presented below in Table 1 as guidance to round the final result. In general, quantity declarations on consumer 

commodities should only be shown to two or three significant digits (for example, 453 g or 85 g). Any final zeros to 

the right of the decimal point need not be expressed. The U.S. customary and SI declarations of quantity must be 

accurate and equivalent to each other. For example, a package bearing a net weight declaration of 2 lb (32 oz) must 

also include an SI declaration of 907 g.

Table 1. Rounding Rules

When the First Digit 

Dropped is:

The Last 

Digit 

Retained is:

Examples

143Bless than 5 Unchanged 2.44 to 2.4

2.429 to 2.4

more than 5, or 5

followed by at least 1 digit

other than 0

Increased by 1 2.46 to 2.5

2.451 to 2.5

5 followed by zeros

Unchanged if 

Even, or 

Increased by 1

if Odd

2.450 to 2.4

2.550 to 2.6

(a) When the first digit discarded is less than 5, the last digit retained should not be changed. For example, if

the quantity 984.3 is to be declared to 3 significant digits, the number 3 to the right of the decimal point must

be discarded since it is less than 5 and the last digit to be retained (the number 4) will remain unchanged.

The rounded number will read 984. The same rationale applies to numbers declared to two significant digits

(for example 68.4 and 7.34); again, the final digit is dropped and the last digit retained remains unchanged

so that the “rounded-off” numbers become 68 and 7.3 respectively.

(b) When the first digit to be discarded is greater than 5, or it is a 5 followed by at least one digit other than zero,

the last digit to be retained should be increased by one unit.

Examples:

984.7 becomes 985

984.51 becomes 985

6.86 becomes 6.9

6.88 becomes 6.9

(c) When the first digit to be discarded is exactly 5, followed only by zeros, the final digit to be retained should

be rounded up if it is an odd number (1, 3, 5, 7, or 9), but no adjustment should be made if it is an even

number (2, 4, 6, or 8).

Examples:

984.50 becomes 984

985.50 becomes 986

68.50 becomes 68

7.450 becomes 7.4

7.550 becomes 7.6

*NOTE: See additional examples in Table 2.

3. Additional Advice on Rounding and Significant Digits

(a) These rules require the packer to use good judgment in making decisions on how to round and the number of

significant digits to use in quantity declarations. Rounding should always be done in one step; for example,

if 16.946 47 g has to be rounded to three significant digits, it should be rounded to 16.9 g, not 16.946 5, then

to 16.946, then to 16.95 which would then round to 17.0 g (see rounding rules above).
Handbook 130 – 2018 IV. Uniform Regulations

A. Uniform Packaging and Labeling Regulation

UPLR Appendix B: Converting U.S. Customary Units to SI Units

93

(b) Do not use rounded SI values to calculate quantities. For example, using 1 in = 25.4 mm, rounded to 25 mm,

should not be multiplied by 2 to determine the SI equivalent for 2 in. The SI equivalent for 2 in is determined

by multiplying 2 in × 25.4 mm = 50.8 mm, then rounding to 51 mm.

(c) If a dimension given as 8 ft is valid to the nearest 1

/10 in, consider it to mean 96.0 in and treat it as having

3 significant digits. The rounded dimension would then be 2.44 m instead of 2.4 m.

(d) Conversions using a multiple digit conversion factor usually give a product with more digits than the original

quantity. The final product should contain no more significant digits than are contained in the number with

the fewest significant digits used in the conversion. For example, the area of a sheet of paper is determined

on a calculator by multiplying 1.25 cm (length) × 1.5 cm (width) = 1.875 cm2

. The product given to

four significant digits on the calculator cannot be any more accurate than two significant digits (the number

of significant digits in 1.5 cm), so the area should be declared as 1.9 cm2

.

(e) Packagers of consumer commodities should be aware that when a converted value is rounded up, there may

be a need to (1) increase the package contents and/or, (2) select a converted value that does not exaggerate

the precision of the quantity or overstate the net contents. For example, under the rules above, a net weight

declaration of 16 oz (453.592 37 g) may be rounded up to 454 g for three significant digits. Inspections by

weights and measures officials are typically conducted using devices with a resolution of 0.5 g or less. If the

packer does not address this possibility, some lots of commodities may pass when the U.S. customary

declaration is tested, but fail when the SI declaration is verified.
