The label is the law

What the label must carry

On this page11
Nine required items, and the label is approved as part of the registration rather than written after it.

The nine

Name, brand or trademark. Name and address of the producer or registrant. Net contents. EPA registration number. EPA establishment number. Ingredient statement. Hazard and precautionary statements. Directions for use. Use classification.

Two of them are issued, not chosen

The EPA registration number identifies the product and the establishment number identifies where it was produced. Neither exists until the relevant process has happened, and both must appear.

The establishment number is about the facility

Which means it can differ between production runs of the same product if they were made in different places. That is a labeling consequence of a manufacturing decision.

Directions for use are mandatory and binding

It is unlawful to use a registered pesticide in a manner inconsistent with its labeling. The directions are not advice; they are the permitted uses, and anything not on the label is outside them.

Which is why the label is the product

Two chemically identical products with different approved directions are different products in law. The document is doing work no other label in this library does.

Net contents for a liquid is measured at a temperature

Stated in terms of liquid measure at 68 F, in standard American units. For a solid it is weight in avoirdupois pounds and ounces.

Use classification

General use or restricted use. A restricted use pesticide carries a statement to that effect, and that single classification changes who may buy the product and through what channel.

Build the panel around the nine

They are not negotiable and several have prescribed positions. The brand design is what fits in the space left over, which is the opposite of how most packaging is designed.

The signal word sets the tone of the front

Danger, Warning or Caution follows from the toxicity category, and it is the first thing a buyer reads. A product whose chemistry puts Danger on the front is a different product on a shelf from one that says Caution, whatever the brand does.

Precautionary statements are not boilerplate

Personal protective equipment, environmental hazards and first aid all follow from the specific product. Borrowing the block from a competitor is how a label ends up requiring equipment your product does not need, or omitting what it does.

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". The ingredient statement is normally required on the front panel. law.cornell.edu
Written from 40 CFR 156.10, 165.25 and 157.22, and from the catalog as it stood on 18 October 2026. A pesticide may not be distributed or sold in the United States unless it is registered, and the label is approved as part of that registration; nothing here is a substitute for EPA guidance on a specific product, and whether a given product is a pesticide at all is a determination with consequences.
