§1581 Prohibitions Relating to Importations

Last updated Sep 23, 2026|Official source

Summary

Bans importing seeds that have noxious-weed seeds or that are labeled in a false or misleading way. It also bans seed screenings meant for planting, with an exception for screenings of certain common grains and pulses (like wheat, oats, corn, soybeans, and similar crops) if they are declared and brought in only for cleaning, processing, or manufacturing and not for planting. If a seed lot contains 10 percent or more other agricultural or vegetable seeds, it may only be imported if the invoice and any labels show a lot ID and name every kind and variety present in any amount, and name any agricultural seed that makes up more than 5 percent. Hybrid seed that is more than 5 percent must be labeled as hybrid. Seeds sold for planting that have been chemically treated must have labels saying they were treated, giving the chemical name used, carrying an approved warning if the residue is harmful to people or animals (very toxic treatments must show a skull-and-crossbones and the words “This seed has been treated with POISON” in red on a contrasting background), and giving an approved description of the treatment process.
