(a) Approved ports of entry. Any plants for planting required to be imported under a written permit in accordance with § 319.37-5(a), if not precleared, must be imported or offered for importation only at a USDA plant inspection station, unless the Plants for Planting Manual indicates otherwise. Ports of entry through which plants for planting must pass through before arriving at these USDA plant inspection stations are listed in the Plants for Planting Manual. All other plants for planting may be imported or offered for importation at any Customs designated port of entry indicated in 19 CFR 101.3(b)(1). Exceptions may be listed in § 330.104 of this chapter. Plants for planting that are required to be imported under a written permit that are also precleared in the country of export are not required to enter at an inspection station and may enter through any Customs port of entry. Exceptions may be listed in § 330.104 of this chapter.

(b) Notification upon arrival at the port of entry. Promptly upon arrival of any plants for planting at a port of entry, the importer shall notify the Plant Protection and Quarantine Programs of the arrival by such means as a manifest, Customs entry document, commercial invoice, waybill, a broker's document, or a notice form provided for that purpose.

(c) Inspection and treatment. Any plants for planting may be sampled and inspected by an inspector at the port of first arrival and/or under preclearance inspection arrangements in the country in which the plants for planting were grown, and must undergo treatment in accordance with part 305 of this chapter if treatment is ordered by the inspector. Any plants for planting found upon inspection to contain or be contaminated with quarantine pests that cannot be eliminated by treatment will be denied entry at the first United States port of arrival and must be destroyed or shipped to a point outside the United States.

(d) Disposition of plants for planting not in compliance with this subpart. The importer of any plants for planting denied entry for noncompliance with this subpart must, at the importer's expense and within the time specified in an emergency action notification (PPQ Form 523), destroy, ship to a point outside the United States, treat in accordance with part 305 of this chapter, or apply other safeguards to the plants for planting, as prescribed by an inspector, to prevent the introduction into the United States of quarantine pests. In choosing which action to order and in setting the time limit for the action, the inspector shall consider the degree of pest risk presented by the plant pest associated with the plants for planting, whether the plants for planting are a host of the pest, the types of other host materials for the pest in or near the port, the climate and season at the port in relation to the pest's survival range, and the availability of treatment facilities for the plants for planting.

(e) Removal of plants for planting from port of first arrival. No person shall remove any plants for planting from the port of first arrival unless and until notice is given to the collector of customs by the inspector that the plants for planting has satisfied all requirements under this subpart.
