Immediately upon arrival of any shipment of plants or plant products (including noxious weeds) subject to this part and covered by a specific permit, the importer shall submit to an inspector notice of such arrival using a form provided for that purpose (Form PPQ-368) and, where relevant, the proposed routing to the proposed U.S. port of exit. Forms will be submitted using a U.S. Government electronic information exchange system or other authorized method. Notice of arrival shall not be required for other products or articles subject to this part since other available documentation meets the requirement for this notice.
