Importation of Plant Parts for Propagation

Restricted plants or plant parts are inspected and treated if necessary for large pests, such as insects, at a port of entry or at an APHIS-PPQ inspection station.

Postentry plants or plant parts are inspected upon entry but must also be grown at an approved site where a state official inspects the growing plants for pests. Both restricted and postentry genera can be imported in commercial quantities.

Prohibited plants or plant parts for propagation are known to carry small plant pathogens or insects that can not be reliably detected by inspection, because the pests are too small, they occur inside the plant tissue, and/or they do not cause consistent symptoms in dormant or growing plants. Prohibited plant material for propagation can only be imported in small quantities through an APHIS-approved quarantine program, unless they originate from an approved source listed in 319.37-5.
