What is a toxin?
A toxin is a poisonous substance produced within living cells or organisms. Toxins can be small molecules, peptides, or proteins that are capable of causing disease on contact with or absorption by human tissues. Examples of toxins: abrin, botulinum toxin, diacetoxyscirpenol, ricin, shiga toxin, tetanus toxin, tetrodotoxin.
Toxins are of biological origin. Man-made substances are not toxins. Toxic substances not produced within living organisms are labeled as "toxicants" or "toxics."
If your product does not fall in line with the definition of a toxin, you do not have to mark it as a restricted item for routing to EH&S.
