A label is only worth printing if it is right
Panelry's whole value is that its labels are correct. This page is how that is checked, in enough detail that you could check it yourself.
- 208
- CFR sections watched for amendment
- 51
- state and DC rulebooks, each with a verification date
- 900+
- automated checks run before every release
- 58
- ingredient weights, each traced to a USDA portion
Every rule is read from the regulation, not remembered
The fastest way to break a label tool is to “fix” it against a half-remembered rule. So the working rule here is simple: nothing is called a requirement until the sentence has been read, all of it, from the eCFR or the U.S. Code. The exceptions live in the second half of long sentences, after “except that” or “provided that”, and a search-engine summary never includes them. Two rules on early versions of this site cited a regulation that does not exist, because they were written from memory. That is the failure this method exists to prevent.
The numbers are derived, never typed
Every Daily Value, every rounding increment, every reference serving amount is transcribed from its section and pinned by an automated check that fails if the number and the citation disagree. Ingredient weights work the same way: each density in the table records the USDA portion it was computed from, and a check re-derives it from that portion on every run. Doing it that way found an error in a value that had already shipped, cocoa powder at 29 percent over its USDA weight, that no one could see because there had been no arithmetic to check.
The product refuses what it cannot do correctly
A dietary supplement does not get a Nutrition Facts panel from Panelry; it gets an explanation of why it needs a different document. The same for foods for infants and toddlers, for products that need a second “as prepared” column, and for labels partly in another language. A tool that produces a confident wrong label is worse than one that says no, so where the rules put a product outside what Panelry builds, it says so and points you to the right place.
Every cited section is watched for change
Regulations move. Before a release, an automated check asks the eCFR for the current amendment date of every section the code cites and reports any that has changed since it was last read. Each state's rulebook carries the date each of its facts was last verified against the state's own text, plus the effective date of any change already announced, so a record that is about to describe the old law says so before the date arrives. On its first run the state check found a state that had deleted its guidance and a disclosure on this site missing half of what the statute now requires. Both were fixed the same day.
What this cannot check
Honesty about the limits is part of the method. A Nutrition Facts panel computed from ingredient data is permitted by the regulations, but compliance is judged on what a laboratory finds in the finished food, and the two can differ. Panelry cannot see your kitchen: shared equipment, cross-contact, whether the product was pasteurised, whether your sales are under your state's cap. It takes what you type at face value and says so beside the export button. And it is a labeling tool, not legal advice.
If you find a rule Panelry has wrong, please tell us. It will be read, from the text, and fixed.
