Section 319.37-11 - Packing and approved packing material(a) Plants for planting for importation into the United States must not be packed in the same container as plants for planting whose importation into the United States is not authorized pending pest risk analysis in accordance with § 319.37-4 .(b) Any plants for planting at the time of importation or offer for importation into the United States shall not be packed in a packing material unless the plants were packed in the packing material immediately prior to shipment; such packing material is free from sand, soil, or earth (except as designated in the Plants for Planting Manual); has not been used previously as packing material or otherwise; and is approved by the Administrator as not posing a risk of introducing quarantine pests. Approved packing materials are listed in the Plants for Planting Manual.(c) If the Administrator determines that a new packing material may be added to the list of packing materials, or that a packing material currently listed should no longer be approved, APHIS will publish in the FEDERAL REGISTER a notice that announces our proposed determination and requests comment on the change. After the close of the comment period, APHIS will publish another notice informing the public of the Administrator's decision on the change to the list of approved packing materials.Approved by the Office of Management and Budget under control number 0579-0190
