4 Certain terrestrial plants listed in Appendices I, II, or III of the Convention or determined by the U.S. Department of the Interior to be endangered or threatened or similar in appearance to endangered or threatened species are required to be accompanied by documentation at the time of importation, exportation, or reexportation (see 50 CFR chapter I). Plants are allowed to be imported, exported or reexported only at ports authorized for such purposes by the U.S. Department of the Interior, or, under certain circumstances as determined by the U.S. Department of the Interior, at nondesignated ports, pursuant to section 9(f) of the Act (16 U.S.C. 1538(f)). (see 50 CFR part 24 for a list of designated ports.)

Any terrestrial plant which is to be imported, exported, or reexported by means other than mail and which may be imported, exported, or reexported under 50 CFR part 17 or part 23 only if accompanied by documentation, shall at the time of importation, exportation, or reexportation plainly and correctly bear on the outer container or on a tag, invoice, packing list, or other document accompanying the plant, the following information:

Genus and species, and quantity of each (if a hybrid, genus of each parent, and quantity of each hybrid),

Country and locality where collected from the wild or where produced from cultivated stock,

Name and address (in the United States if exported or reexported) of shipper, owner or person shipping or forwarding the plants,

Name and address (in the United States if imported) of consignee,

Identifying shipper's mark and number, and

Serial number and type (e.g., permit, certificate) of document issued for the importation, exportation, or reexportation of the plant.

Promptly upon arrival at a port of import (listed in 50 CFR part 24, or, if allowed by the U.S. Department of the Interior, at a nondesignated port) of any terrestrial plant which is imported by means other than mail and which may be imported under 50 CFR part 17 or part 23 only if accompanied by documentation, the importer shall notify Plant Protection and Quarantine of the arrival and of the genus and species of the plant by such means as a manifest, Customs entry document, commercial invoice, waybill, broker's document, or notice form provided for that purpose.

Prior to the exportation or reexportation of any terrestrial plant which is to be exported or reexported by other than mail and which may be exported or reexported under 50 CFR part 17 or part 23 only if accompanied by documentation, the exporter or reexporter shall notify Plant Protection and Quarantine of the intended exportation or reexportation and of the genus and species of the plant by such means as a manifest, commercial invoice, waybill, broker's document, or notice form provided for that purpose.
