Title 7 › Chapter CHAPTER 37— - SEEDS › Subchapter SUBCHAPTER II— - INTERSTATE COMMERCE › § 1571
It is illegal to move or ship seeds across state lines unless their containers have the required labels and meet other rules. For agricultural seed mixes, labels must show the name and percent by weight of any seed that is more than 5% of the mix, say if a seed is a hybrid, and for lawn/turf mixes say “mixture” and list components by amount. Labels must also show a lot number, the origin when that origin matters and is known (or say “origin unknown”), percent weed seeds and any noxious weed types with their allowed rates, percent other agricultural seed, percent inert matter, germination and hard-seed percentages for components over 5% (and for small components 5% or less), and the month and year the germination test was done (for mixtures it’s enough to give the oldest test date). Labels must give the name and address of the shipper or the buyer for resale (a code approved by the Secretary of Agriculture may be used), and the month and year after which any inoculant is no longer claimed effective. Vegetable seed labels have similar rules, with different details for containers one pound or less and for containers over one pound; if germination is below the standard the label must include the words “Below Standard” and test results. Seeds must have germination tests done within the five months before shipment unless the Secretary of Agriculture allows a shorter or longer period for certain seeds. It is also illegal to ship seeds with false labels or false advertising. Seeds that must be stained but are not stained, seeds stained to look like required-stained seed, mixtures of differently stained seeds, and certain mixtures with U.S.-grown seed are banned. Screenings are banned for seeding unless they are labeled or invoiced as only for cleaning, processing, or manufacturing. Treated seeds must be labeled that they were treated, name the chemical used, give an approved caution if harmful (for example “Do not use for food or feed or oil purposes”), and, for mercurial-type poisons, show a skull-and-crossbones and a statement such as “This seed has been treated with POISON” in red letters on a contrasting background, plus a description of the treatment process.
