Inspectors shall make local arrangements, in accordance with policies of the Plant Protection and Quarantine Programs, with the Collector of Customs for the release by Customs officers on behalf of the inspector of any class of means of conveyance, their stores, baggage, mail, or other products or articles when such arrangements do not increase unduly the danger of plant pest dissemination and will facilitate clearance of means of conveyance, baggage, mail, or other products or articles.

Inspection of domestic movements. For the purpose of preventing the interstate movement of plant pests, provisions requiring inspection of means of conveyance and products or articles moving interstate may be issued as regulations in association with quarantines in part 301 or part 318 of this chapter or in this part.
