The label is the law

The ingredient statement

On this page10
On the front, not the back. That single rule reshapes the panel.

The rule

The ingredient statement is normally required on the front panel of the label.

Why that is unusual

Cosmetics, cleaning products and foods all put the ingredient list on a back or side panel. Here it competes directly with the brand name and the product claim for the most valuable area on the package.

Active and inert

The statement distinguishes the active ingredients, named with their percentages, from the inert ingredients given as a total. The actives are what the registration is about.

Percentages have to add up

Actives plus inerts total 100 percent. It is arithmetic, it is checkable by anyone, and it is the kind of error that survives several rounds of proofing because nobody adds it up.

It binds the formula to the label

A percentage on a front panel is a statement about what is in the bottle. A reformulation that moves an active by a fraction of a percent is a label change.

Plan the front panel in three parts

Brand and product identity, the ingredient statement, and the signal word with its hazard statements. Those three share the front and the rest goes elsewhere.

Which rules out some containers early

A narrow cylinder with a small front panel cannot carry three blocks at a legible size. Measure the panel against the three before choosing between bottles, not after.

Inerts are not inactive

The word means they are not the registered active, not that they do nothing. Solvents, surfactants and carriers all sit in that total, and several of them are the reason the container has a chemical resistance problem at all.

The statement is also your supplier check

To state the percentages you have to know them, which means a certificate of analysis on every incoming active rather than a trade name and a promise. A producer who cannot evidence the numbers on the front panel has a supply problem before a labeling one.

40 CFR 156.10, general labeling requirements for pesticides. The label carries the name, brand or trademark; the name and address of the producer or registrant; the net contents; the EPA registration number; the EPA establishment number; the ingredient statement; hazard and precautionary statements; directions for use; and the use classification. Required text must be "clearly legible to a person with normal vision", set in 6-point or larger type, on a clear contrasting background, not obscured or crowded, and placed so as "to render it likely to be read and understood by the ordinary individual under customary conditions of purchase and use".
