Polyunsaturated fat — FDA label rounding
Polyunsaturated fat has no FDA Daily Value and is declared voluntarily — it appears on a Nutrition Facts label only when a manufacturer chooses to list it, or when a related claim requires it. It does have a rounding rule, set by § 101.9(c)(2)(iii).
Polyunsaturated fat rounding rules
Amount
| Amount range | Rounding rule |
|---|---|
| 0 to <0.5 | declared as 0g |
| 0.5 to 5 | nearest 0.5g |
| ≥5 | nearest 1g |

Frequently asked questions
Every figure on this page traces to a paragraph of 21 CFR 101.9. These are those paragraphs, in full.
What is the FDA Daily Value for Polyunsaturated fat?
Polyunsaturated fat has no established FDA Daily Value, so it never carries a %DV on the Nutrition Facts label — it is still declared under 21 CFR 101.9.
How is polyunsaturated fat rounded on a Nutrition Facts label?
Polyunsaturated fat content shall be indented and expressed as grams per serving to the nearest 0.5 (1/2) gram increment below 5 grams and to the nearest gram increment above 5 grams. If the serving contains less than 0.5 gram, the content shall be expressed as zero.
Note: Polyunsaturated fat is declared voluntarily, except where a fatty-acid claim is made.
How do I find out how much polyunsaturated fat is in a food?
A Daily Value is a reference target, not a measurement of any particular food. To find the polyunsaturated fat content of a specific ingredient or product, look it up in USDA FoodData Central, then use that amount here to see what a label would declare and what %DV it carries.
