(a) If you import a restricted organism through a land border port in the United States by commercial vehicle (i.e., automobile or truck), then the person carrying the restricted organism must present the permit required by § 322.14 and an invoice or packing slip accurately indicating the complete contents of the shipment to the inspector at the land border port.

(b) The restricted organisms must be surrendered at the port of entry and can continue on to the destination identified on the permit only by a bonded carrier (commercial express delivery).

(c) If you fail to present a copy of the permit and an invoice or packing list accurately indicating the complete contents of the shipment at the port of entry, an inspector will refuse the organism's entry to the United States or confiscate and destroy the refused material.
