5% Deviation Threshold for Nutrient Labels Act

Imposes a 5% tolerance on declared nutrient values, tightening labeling enforcement and forcing FDA rule updates.

The Brief

The bill amends the Federal Food, Drug, and Cosmetic Act to define misbranding when the nutrient content on labeling deviates by more than 5% from the declared value for nutrients required on the label. It adds a new subsection to Section 403(q)(2) and requires the Secretary of Health and Human Services, through the FDA, to revise regulations within 60 days of enactment to implement the change.

This creates a uniform standard for nutrient labeling accuracy and sets expectations for enforcement and compliance across packaged foods.

At a Glance

What It Does

Adds a new misbranding trigger: if nutrient content exceeds 5% of the declared value for nutrients on the label, the food is misbranded. It adds subparagraph (C) to FD&C Act Section 403(q)(2).

Who It Affects

Packaged food manufacturers and labelers, FDA labeling enforcement staff, and third-party auditors who verify nutrient declarations on foods regulated under the FD&C Act.

Why It Matters

Provides a clear, enforceable standard for labeling accuracy and prompts timely regulatory updates, reducing consumer confusion and potential misrepresentation.

What This Bill Actually Does

The bill introduces a hard 5% threshold for nutrient labeling accuracy. Under the amendment to Section 403(q)(2) of the FD&C Act, a food will be deemed misbranded if the nutrient content claimed on the label is more than 5% greater than the actual nutrient content for nutrients required to appear on the label (as identified in subparagraphs (1)(C), (1)(D), and (1)(E)).

In addition to establishing this misbranding standard, the bill requires the Secretary of Health and Human Services, via the Commissioner of Food and Drugs, to revise the applicable labeling regulations within 60 days after enactment to reflect the new threshold. This ensures a rapid alignment between law and regulatory practice, aiming to improve labeling accuracy for consumers and professionals who rely on these data.

The proposed rule affects foods subject to existing nutrition labeling requirements and places new compliance expectations on manufacturers and QA programs that verify nutrient declarations.

The Five Things You Need to Know

1

The bill creates a 5% deviation threshold for nutrient values on labeling; exceedance triggers misbranding.

2

Misbranding is defined by adding new subsection (C) to FD&C Act 403(q)(2).

3

The change applies to nutrients required by subparagraphs (1)(C), (1)(D), and (1)(E) on the label.

4

FDA must revise 21 CFR 101.9 regulations within 60 days of enactment to implement the threshold.

5

Introduced January 15, 2026, in the 119th Congress by Rep. Greg Steube with co-sponsors Soto and Donalds.

Section-by-Section Breakdown

Section 1

Short title

This section designates the act as the Ensuring Consistency in Nutrition Labels Act. It establishes the bill's identity and clarifies that its provisions apply to misbranding rules governing nutrient labeling under the FD&C Act.

Section 2(a)

Misbranding for 5% deviation in nutrient value

Section 403(q)(2) is amended by adding a new subparagraph (C). It states that if the nutrient content declared on the label for nutrients required to appear on the label is greater than 5% in excess of the actual nutrient content, the food shall be treated as misbranded. This creates a concrete, numeric standard for enforcement and reduces ambiguities around labeling accuracy.

Section 2(b)

Regulatory updates

The bill directs the Secretary of Health and Human Services, acting through the FDA Commissioner, to revise regulations under 21 CFR 101.9 within 60 days after enactment to reflect the new 5% deviation standard. This ensures that the administrative framework aligns with the statutory change and provides implementable guidance for industry.

Who Benefits and Who Bears the Cost

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.

Who Benefits

  • Consumers who rely on nutrition labels for diet planning gain clearer, more consistent information and reduced risk of over- or under-stated nutrient content.
  • Dietitians and nutrition professionals receive more reliable data to inform clinical guidance and public health recommendations.
  • FDA labeling enforcement staff gain a clear, enforceable threshold to apply when assessing label accuracy.
  • QA and compliance teams in food manufacturing benefit from a precise standard to align internal testing and labeling processes.

Who Bears the Cost

  • Small and mid-sized food manufacturers may face higher QA and testing costs to maintain nutrient accuracy within the 5% threshold.
  • Importers and foreign suppliers may need to adjust labeling or documentation to meet US 5% deviation requirements.
  • Labeling vendors and contract manufacturers may incur transitional costs to update systems, tooling, and tests.
  • Regulatory agencies could see increased workload related to enforcement actions and oversight during the transition period.

Key Issues

The Core Tension

Balancing stringent labeling accuracy with the practical realities of testing variability and manufacturing diversity.

The 5% deviation standard imposes a precise numeric threshold that could be complicated by measurement variability, batch-to-batch variation, and rounding practices. Different nutrients may have different testing methods and tolerances, and the definition of “composite” nutrient content could raise questions for foods with multi-ingredient formulations or fortified products.

The requirement to update 21 CFR 101.9 within 60 days emphasizes regulatory agility, but practical implementation will require guidance on measurement protocols, batch acceptance criteria, and transitional labeling obligations. The bill does not specify grace periods or exemptions for minor reformulations or temporary supply chain disruptions, which could create short-term compliance pressure for manufacturers.
