56 Plants

561 General

Plants and plant products are mailable within the United States and its territories and possessions, but are subject to certain prohibitions and restrictions imposed by federal agricultural and conservation statutes. When these prohibitions and restrictions render the shipment of any plant or plant product as unlawful, then those plants are nonmailable. For more information, see Publication 14, Prohibitions and Restrictions on Mailing Animals, Plants, and Related Matter.
