"high protein" on your bag just voided your FDA exemption
Two words on the front of your bag can undo your entire exemption. Under 21 CFR 101.9(j)(18), the FDA small business nutrition labeling exemption does not apply to any product bearing a nutrient content claim, a health claim, or other nutrition information — on the label, in labeling, or in advertising. "High protein" is a nutrient content claim. Your exemption for that product is gone.

Here is how it happens. You checked the thresholds: under 100 employees, under 100,000 units. You filed the annual notice. Then the packaging came back from your designer with HIGH PROTEIN in the corner of the pouch. Nobody asked a lawyer, because it did not feel like a legal statement. It felt like marketing.
It is not marketing. It is a regulated claim with a numeric threshold attached. Using it removes your exemption, obligates a compliant Nutrition Facts panel, and, if the number misses the threshold, misbrands the product on a second, independent ground.
What a nutrient content claim actually is
A nutrient content claim is any statement that "expressly or implicitly characterizes the level of a nutrient" of the type required in nutrition labeling. The definition is at 21 CFR 101.13(b). Two flavors:
Express claims. A direct statement about the level or range of a nutrient. FDA's examples: "low sodium," "contains 100 calories."
Implied claims. Statements describing the food or an ingredient in a way that suggests a nutrient is absent or present, or that suggest the food helps you meet dietary guidelines because of its nutrient content. FDA's example is "high in oat bran." Nobody said "high fiber," but the claim is there.
The structural rule matters more than most founders realize. Under 101.13(b), a nutrient content claim may not be made unless it is defined by regulation in Subpart D of Part 101 and used exactly as defined. FDA does not keep a list of banned phrases. It keeps a list of permitted ones. If your phrase characterizes a nutrient level and FDA never defined it, the phrase is not allowed at all. That is why there is no compliant way to put "low carb" on a conventional food label: "low" is a defined term, carbohydrate is not one of the nutrients it is defined for, and Subpart D has no carbohydrate-level claim. "Keto" is a harder call, and we take it up below.
The phrases that are nutrient content claims
Every term below is defined in Subpart D and carries a numeric condition. Not exhaustive, but it covers what shows up on small-brand packaging.
| Claim term | Defined at | The condition, in short |
|---|---|---|
| Free (also zero, no, without, trivial source of) | 101.60–101.62 | Per RACC and per labeled serving: calories < 5, sugars < 0.5 g, fat < 0.5 g, sodium < 5 mg, cholesterol < 2 mg. |
| Low | 101.60–101.62 | Per RACC and per labeled serving: calories ≤ 40, fat ≤ 3 g, saturated fat ≤ 1 g and ≤ 15% of calories, sodium ≤ 140 mg (very low ≤ 35 mg), cholesterol ≤ 20 mg. If the RACC is 30 g or less, or 2 tablespoons or less, the food must also meet the limit per 50 g. |
| Reduced / less / fewer | 101.60–101.62 | At least 25% less than a reference food, with the reference food and percentage declared. |
| Light / lite | 101.56 | Depends on the reference food. If it draws 50% or more of its calories from fat, fat must be cut 50%, and that is the only route. If it draws less than 50% of calories from fat, you may either cut calories by at least one third or cut fat by 50%. "Light in sodium" means sodium cut 50%. Quantitative comparison required. |
| High / rich in / excellent source of | 101.54 | 20% or more of the RDI or DRV per RACC. |
| Good source / contains / provides | 101.54 | 10 to 19% of the RDI or DRV per RACC. |
| More / added / extra / plus / fortified / enriched | 101.54 | At least 10% more of the RDI or DRV per RACC than a reference food. Available only for protein, vitamins, minerals, dietary fiber, or potassium. |
| Lean | 101.62 | Per RACC and per 100 g: < 10 g fat, ≤ 4.5 g saturated fat, < 95 mg cholesterol. |
| Extra lean | 101.62 | Per RACC and per 100 g: < 5 g fat, < 2 g saturated fat, < 95 mg cholesterol. |
| No added sugars | 101.60 | No sugars or sugar-containing ingredients added, and the food normally contains added sugars. Disclosure statement required. |
| No salt added / unsalted | 101.61 | No salt added in processing and the comparable food is normally salted. If not sodium free, it must say so. |
| High potency | 101.54 | 100% or more of the RDI per RACC for that vitamin or mineral. |
| Healthy | 101.65 | Final rule published December 27, 2024, effective April 28, 2025, compliance February 2028. |
All of these are claims: "high protein," "excellent source of protein," "good source of fiber," "high fiber," "low sodium," "sugar free," "zero sugar," "no added sugar," "fat free," "reduced fat," "light," "lean," "extra lean," "calorie free," "more calcium," "fortified with iron."
One extra trap on protein. A protein claim triggers 21 CFR 101.9(c)(7)(i): you must then declare a percent Daily Value for protein in the panel, calculated on a protein-quality-corrected basis, not raw grams. Plant-protein brands routinely find the corrected number lands under the 20% needed for "high."
The phrases that generally are not
These do not characterize a nutrient level, so on their own they are not nutrient content claims:
- Flavor and identity descriptors. "Dark chocolate," "extra sharp cheddar," "original recipe," "artisan," "small batch."
- Ingredient presence statements. "Made with real butter," "made with whole grain," "made with oat bran." Compare "high in oat bran," which FDA cites as an implied claim. The difference is one word.
- Nonnutritive substance statements. "Contains no preservatives," "no artificial colors."
- Allergen avoidance statements. "100% milk free," where the point is avoidance rather than nutrient level.
- Gluten free. A descriptive claim under 21 CFR 101.91 requiring under 20 ppm gluten. Enforceable, but not a nutrient content claim.
- Organic is USDA territory, and non-GMO is not a nutrient claim either.
- "Light" for color or texture. "Light brown sugar" and "light and fluffy" are fine under 101.56 if the label makes clear what is described.
Two are genuinely context-dependent, and pretending otherwise would do you a disservice:
A bare quantitative statement like "100 calories" or "5 g of fat." Under 101.13(i)(3), stating an amount without characterizing the level is not a nutrient content claim. But it is nutrition information, and the exemption falls to "any nutrient content claim, health claim, or other nutrition information." For exemption purposes, "100 calories per bar" is as fatal as "low calorie." Deleting the word "high" is not always enough.
"Keto." FDA has never defined it, and it has never said publicly whether "keto" counts as a nutrient content claim. The argument that it does goes like this: shoppers read it as a statement about carbohydrate level, that makes it an implied claim, and 101.13(b) permits only claims defined in Subpart D. That reasoning is sound but untested, and no FDA rule or warning letter settles it. "Low carb" is the clear-cut case. Treat "keto" and "macro friendly" as risky, not safe.
The claim does not have to be on the package
Reread the operative sentence from FDA's exemption guidance: the exemption does not apply if the claim appears "on the label, or in labeling or advertising."
Advertising. That is what catches brands who kept the package clean.
Your Amazon bullet points. Your Shopify product description. The Instagram caption where you wrote "packed with 12g of protein." The sell sheet you emailed a distributor. Any of them voids the exemption for that product, even if the pouch says nothing but the product name.
A package gets printed once. Marketing copy gets written continuously, by whoever runs the account that week. If you rely on the exemption, make this a written rule for your marketing, not something the founder remembers.
Health claims and structure/function claims are separate problems
Health claims (21 CFR 101.14) characterize a relationship between a substance and a disease or health-related condition: "calcium may reduce the risk of osteoporosis." There are two routes to using one. FDA either authorizes the claim by regulation, or it permits a qualified health claim through a letter of enforcement discretion, which requires the claim to carry qualifying language about the strength of the evidence. Either way, the food must also stay under 13 g fat, 4 g saturated fat, 60 mg cholesterol, and 480 mg sodium, measured per RACC, per labeled serving, and, if the RACC is 30 g or less or 2 tablespoons or less, per 50 g. Health claims also void the small business exemption.
Structure/function claims describe a nutrient's role in normal body function: "calcium builds strong bones," "fiber maintains bowel regularity." On dietary supplements these require the 21 CFR 101.93 disclaimer that FDA has not evaluated the statement, plus notification to FDA within 30 days of marketing.
The bright line under all three: any statement that your product treats, prevents, or cures a disease makes it an unapproved drug in FDA's eyes. That is a far worse problem than a labeling violation.
The fix is boring, and cheap
You have two options.
Option 1: drop the claim. Strip nutrient characterizations from the package, website, marketplace listing, and ad copy. Keep flavor and identity language, which sells fine. Then hold your exemption and file the annual notice on time, because FDA does not remind you.
Option 2: keep the claim and put a compliant panel on the product. Verify the number clears the threshold, add the panel, and stop worrying about what your marketing team writes.
Option 2 used to be the expensive one. A lab panel runs $1,609 to $1,724 per sample at Medallion Labs, doubled for rush. Food Consulting Company charges $240 per panel. That math is why brands tried to thread the exemption needle in the first place.
Nutrillius builds a 21 CFR 101.9-compliant Nutrition Facts panel from your recipe in about a minute, for $39 one time, PNG/PDF/SVG, 90 days of edits. At that price, keeping the claim is usually cheaper than the meeting about whether to remove it.
