Net Quantity of Contents: FDA Labeling Requirements
Learn net quantity of contents rules under 21 CFR 101.7, including placement, units, type size, clear space, weight declarations and package accuracy.
Every packaged food sold at retail in the United States must carry a net quantity of contents statement on the front of the package. 21 CFR 101.7 governs where the statement appears, which unit of measure applies, how tall the letters must be, how much clear space surrounds it, and which wording cannot appear inside it.
One clarification matters first. If you have seen 21 CFR 101.105 cited for a food net quantity declaration, it is wrong. That section is not part of the current Title 21, and the food rule has been at 101.7 since it was redesignated at 81 FR 59131 on 29 August 2016.
Net quantity is one of the statements required on every retail food package, alongside the statement of identity, ingredient list, allergen information, and name and place of business. For the complete set, see FDA food labeling requirements.
Where the net quantity statement goes on the package
Paragraph (e) puts the declaration on the principal display panel. If a package has alternate principal display panels, the declaration must appear on each one. A pouch that is equally likely to face outward either way therefore needs the statement twice.
Paragraph (f) contains the placement rule. The wording states that it "shall be placed on the principal display panel within the bottom 30 percent of the area of the label panel in lines generally parallel to the base on which the package rests as it is designed to be displayed."
Three requirements sit inside that sentence:
- It is 30 percent of the area, not the height. On a rectangular panel, the two coincide because the width is constant. On a 6 inch tall, 4 inch wide front covering 24 square inches, the bottom 30 percent of the area is the lower 1.8 inches. On a panel that narrows toward the base, the band containing 30 percent of the area is taller.
- The statement runs parallel to the base as displayed. If the package is designed to sit on its side, the lines run parallel to that face, not necessarily to the bottom edge of the artwork.
- There is one narrow exception. The proviso in (f) removes the bottom 30 percent requirement when the principal display panel is 5 square inches or less, provided the declaration meets the other requirements of the part. Only its position is relaxed.
Net weight labeling requirements: weight, fluid measure or count
Paragraph (a) permits weight, measure, numerical count, or a combination of count and weight or measure, then narrows which one you should use.
The statement must use fluid measure when the food is liquid. It must use weight when the food is solid, semisolid or viscous, or when it is a mixture of solid and liquid.
Dry measure is available only for fresh fruit, fresh vegetables, or another dry commodity customarily sold by dry measure. A firmly established consumer usage and trade custom of declaring a liquid by weight, or a viscous product by fluid measure, may be followed instead.
The mixture rule catches more foods than people expect. Canned beans in liquid and salsa in a jar both declare their quantity by weight.
Paragraph (b) establishes the units:
- Avoirdupois pound and ounce for weight.
- U.S. gallon of 231 cubic inches, with its quart, pint and fluid ounce, for fluid measure.
- U.S. bushel of 2,150.42 cubic inches, with its peck, dry quart and dry pint, for dry measure.
Volume also has a temperature basis. Frozen food sold frozen is measured at the frozen temperature, refrigerated food at 40 degrees F (4 degrees C), and everything else at 68 degrees F (20 degrees C).
Count is the weakest of the three methods. Under (c), when a numerical count does not provide adequate information about the quantity in the package, it must be combined with a statement of weight, measure or size of the individual units. For example, "12 cookies" becomes "12 cookies, net wt 9 oz".
The dual net quantity declaration and what "dual" means
The word dual can refer to two different things here, and confusing them produces labels that look correct but are not.
The dual declaration that 101.7 actually requires exists within the U.S. customary system. Under (j), packages of less than 4 pounds or 1 gallon labeled by weight or fluid measure state the quantity in ounces first.
Once the package reaches 1 pound or 1 pint, the ounce figure is followed in parentheses by the larger unit: pounds with any remainder in ounces or a fraction of the pound, or the largest whole fluid units with the remainder stated in smaller fluid units.
| Quantity | Permitted declaration | Source |
|---|---|---|
| 1 1/2 pounds | "Net Wt. 24 oz (1 lb 8 oz)", "Net Wt. 24 oz (1 1/2 lb)" or "Net Wt. 24 oz (1.5 lb)" | 101.7(m)(1) |
| 3/4 pound | "Net Wt. 12 oz", no parenthetical, being under 1 pound | 101.7(m)(2) |
| 1 quart | "Net 32 fl oz (1 qt)" | 101.7(m)(3) |
| 1 3/4 quarts | "Net 56 fluid oz (1 qt 1 pt 8 oz)", never "(1 quart 24 ounces)" | 101.7(m)(4) |
| 2 1/2 gallons | "Net contents 2 1/2 gallons" or "2 gallons 2 quarts", not "2 gallons 4 pints" | 101.7(m)(6) |
The order is important. Ounces lead, and the larger unit follows in parentheses. The example in (m)(4) also prevents crossing unit families because a remainder after quarts goes to pints or fluid ounces, never to "24 ounces" following a quart.
Above the threshold, the logic changes. Under (k), packages of 4 pounds or 1 gallon or more lead with pounds or the largest whole fluid unit.
Random packages, meaning members of a lot with varying weights and no fixed pattern, may under (j)(2) be declared in pounds and decimal fractions to two places, as in the "Net Wt. .75 lb" example in (m)(5).
Metric is the other meaning of dual, and 101.7 is permissive about it. Paragraph (p) states that a separate metric statement is not regarded as a supplemental statement and that an accurate metric statement may also appear on the principal display panel or other panels.
On its own terms, this section permits the metric figure rather than requiring it, although nearly every U.S. package carries one. The statement in the diagram above, "NET WT 12 OZ (340 g)", is the (m)(2) example with 12 avoirdupois ounces converted to the nearest gram.
Three additional formatting rules complete this part of the section.
Under (j)(3), the declaration may use more than one line. The term "net weight" must be used when stating quantity by weight. "Net" or "net contents" is optional for fluid measure or count because "Net wt 6 oz" and "6 fl oz" already distinguish an avoirdupois ounce from a fluid ounce.
Under (n), the only permitted abbreviations are wt, oz, lb, gal, pt, qt and fl.
Under (d), a common fraction must use halves, quarters, eighths, sixteenths or thirty-seconds and must be reduced to its lowest terms. A decimal fraction cannot extend beyond two places.
Minimum type size for the net quantity of contents
Paragraph (i) sets the minimum letter height according to the area of the principal display panel. The size must also be uniform across all packages of substantially the same size.
| Area of the principal display panel | Minimum letter height | At 72 points to the inch |
|---|---|---|
| 5 square inches or less | 1/16 inch | 4.5 points |
| More than 5 but not more than 25 square inches | 1/8 inch | 9 points |
| More than 25 but not more than 100 square inches | 3/16 inch | 13.5 points |
| More than 100 square inches | 1/4 inch | 18 points |
| More than 400 square inches | 1/2 inch | 36 points |
The point column is arithmetic, not regulation, and it can hide an important design problem.
The CFR measures actual letter height. Paragraph (h)(2) is specific: the heights apply to capital letters, and when lower case is used, the letter "o" must meet the minimum height. A font set at 9 points does not have a 9 point lower case "o", so set the type, print the artwork and measure it.
Paragraph (h) adds two geometric restrictions. The ratio of letter height to width may not exceed a differential of 3 units to 1. This rules out the highly condensed typefaces designers often reach for when space is limited.
Where fractions are used, each component numeral must meet one half of the applicable minimum height.
When the declaration is blown, embossed or molded onto glass or plastic instead of printed, the minimum sizes increase by one sixteenth of an inch.
All these requirements depend on the principal display panel area, which is defined by 101.1 rather than 101.7.
For a rectangular package where one entire side can properly be considered the principal display panel side, the area is the height multiplied by the width of that side.
For a cylinder or near cylinder, it is 40 percent of the height multiplied by the circumference. For any other shape, it is 40 percent of the total surface, unless there is an obvious principal display panel, such as the top of a circular package of cheese.
Exclude tops, bottoms, can flanges, and the shoulders and necks of bottles and jars.
This is where artwork often goes wrong. A jar that is 3 inches in diameter and 5 inches tall looks large, but 40 percent of its 9.42 inch circumference multiplied by 5 inches produces a principal display panel area of 18.8 square inches. That places it in the 1/8 inch type-size band rather than the 3/16 inch band.
Our PDP area and type size calculator applies the 101.1 geometry for each package shape and returns the 101.7(i) minimum in inches, millimeters and points.
Separation, contrast and prohibited wording
Paragraph (f) requires the net quantity declaration to appear as a distinct item. It measures the required clear space using the statement's own type:
- From other printed label information above or below the statement, leave at least a space equal to the height of the lettering used in the declaration.
- From other printed label information to the left or right, leave at least a space equal to twice the width of the letter "N" in the type style used for the statement.
Both gaps therefore scale with your own typography. On the 24 square inch front described above, using the 1/8 inch minimum means the clear space above and below is 1/8 inch.
Paragraph (h) controls readability. The statement must appear in conspicuous and easily legible boldface type, with distinct contrast from other package matter through typography, layout, color, embossing or molding.
Prominence has another layer in 101.15. That section lists reasons a required statement can fail the conspicuousness requirement in section 403(f) of the act, including smallness or style of type, insufficient background contrast, obscuring designs or vignettes, and crowding.
Under 101.15(b), an exemption based on insufficient label space does not apply when the lack of space resulted from giving space to something the act does not require. A crowded front panel is therefore no defense when your own hero graphic created the problem.
There is also a wording restriction. Paragraph (f) says the declaration cannot include any term qualifying a unit of weight, measure or count that tends to exaggerate the amount of food in the container. It specifically names "jumbo quart" and "full gallon".
Paragraph (o) repeats that prohibition for supplemental statements elsewhere on the package, which are otherwise permitted when stated in nondeceptive terms.
Accuracy, drained weight and multiunit packages
Paragraph (g) provides the basic accuracy rule. The declaration must accurately reveal the quantity of food in the package, excluding wrappers and other material packed with it.
Interleaving paper, a desiccant sachet and the tray beneath a cookie therefore do not count toward the declared quantity.
Pressurized containers are the exception. They declare what will be expelled when the instructions on the container are followed, including propellant.
Paragraph (q) recognizes reasonable fill variations. Variations caused by loss or gain of moisture during good distribution practice, or by unavoidable deviations in good manufacturing practice, are permitted. The limit is a standard rather than a numerical percentage: variations cannot be unreasonably large.
Because 101.7 sets no percentage, your fill specification and check-weighing records establish the practical boundaries.
Drained weight appears in 101.7 only in paragraph (t), which is not a retail labeling format rule. It is the narrow route through which a product whose net weight, drained weight or volume does not reflect the actual contents may still be sold to government institutions.
That requires a signed acknowledgment kept on file for 2 years and a shipping container marked "This Product Not for Retail Distribution". When a retail food label must declare drained weight, that requirement comes from the standard of identity or standard of fill for that food.
Multiunit retail packages are addressed by (s). The outside package states the number of individual units, the quantity of each unit and, in parentheses, the total in avoirdupois or fluid ounces, without another parenthetical declaration in the largest whole units.
The regulation's examples are "6-16 oz bottles (96 fl oz)" and "3-16 oz cans (net wt. 48 oz)".
The term applies to units of the identical commodity in the same quantity, with each individual unit capable of being sold on its own in full compliance.
When checking a finished front panel against everything that belongs on it, the FDA label checklist walks through each principal display panel element with its citation.
Net quantity of contents frequently asked questions
Does the net quantity statement always have to be in the bottom 30 percent?
No. Under the proviso in 101.7(f), the bottom 30 percent requirement does not apply when the principal display panel is 5 square inches or less, provided the declaration satisfies the other requirements of the part. Those packages still need the 1/16 inch minimum letter height, required separation from surrounding print, and sufficient contrast.
Does 101.7 require the metric figure in parentheses?
No. The text of 101.7(p) is permissive. A separate metric statement is not treated as a supplemental statement and may appear on the principal display panel or other panels. The dual declaration that this section requires is the customary declaration in (j), with ounces first and the pound or larger fluid-unit equivalent in parentheses once the applicable threshold is reached.
Can I just print "Net Wt 1.5 lb" on a 24 ounce package?
Not by itself. Under 101.7(j)(1), a package under 4 pounds labeled by weight is expressed in ounces, followed by the pound form in parentheses. The three forms permitted by 101.7(m)(1) lead with ounces: "Net Wt. 24 oz (1 lb 8 oz)", "Net Wt. 24 oz (1 1/2 lb)" and "Net Wt. 24 oz (1.5 lb)".
How do I work out the panel area on a jar or bottle?
Use 101.1 rather than the artwork's label dimensions. For a cylindrical or nearly cylindrical container, the area is 40 percent of the height multiplied by the circumference, excluding shoulders, necks and can flanges. For a rectangular carton, use height multiplied by width. For other shapes, use 40 percent of the total surface.
Is net quantity the same as serving size?
No. Net quantity under 101.7 tells the consumer how much food is in the entire package, excluding wrappers and other packing material. Serving size derives from the reference amounts in 21 CFR 101.12 and determines how the Nutrition Facts panel is built. See FDA serving size requirements for the serving-size rules.
Which abbreviations can I use in a net quantity statement?
101.7(n) provides a closed list. The permitted abbreviations are wt, oz, lb, gal, pt, qt and fl, with periods and plurals optional. The regulation says these abbreviations and no others may be used, so you cannot create alternative short forms simply to save space on the principal display panel.
