N.J. Stat. § 4:7-11
If the department has any reason to suspect the presence of a dangerous disease in any shipment of plant material imported from without the state, it may order the examination of every package of such material, in transit or at the point of delivery, and shall not authorize its acceptance or delivery until satisfied that no dangerous disease is present.
When inspection is considered necessary the department shall at once notify the carrier for hire to that effect, which carrier shall thereupon hold the material subject to the further order of the department. The department shall make any necessary inspection of material in transit or at point of destination as promptly as possible after notice of its arrival within the state. The department may in its discretion authorize the delivery of any plant material to the consignee, subject to inspection at unpacking.
If no inspection is considered necessary the department shall at once notify the carrier for hire and the consignee, to that effect, which notice shall serve as an authority for the delivery and receipt of the material.
