(a) Manifest required. Trucks with merchandise transiting Canada from point to point in the United States will be manifested on United States-Canada Transit Manifest, Customs Form 7512-B Canada 8 1/2. The driver shall present the manifest in four copies to U.S. Customs at the United States port of departure for review and validation.

(b) Procedure at United States port of departure. The Customs officer receiving the manifest shall validate it by stamping each copy in the lower right hand corner to show the port name and date and by initialing each copy. All copies of the validated manifest then will be returned to the driver for presentation to Canadian Customs at the Canadian port of entry.

(c) Procedure at Canadian ports of arrival and exit. Truck shipments transiting Canada shall comply with Canadian Customs regulations. These procedures generally are as follows:

(1) Canadian port of arrival. The driver shall present a validated United States-Canada Transit Manifest Customs Form 7512-B Canada 8 1/2, in four copies to the Canadian Customs officer, who shall review the manifest for accuracy and verify its validation by U.S. Customs. If the manifest is found not to be properly validated, the truck shall be required to be returned to the United States port of departure so that the manifest may be validated. If the manifest is validated properly and no irregularity is found, the truck will be sealed unless sealing is waived by Canadian Customs. The original manifest will be retained by Canadian Customs at the port of arrival, and the three copies will be returned to the driver for presentation to Canadian Customs at the Canadian port of exit.

(2) Canadian port of exit. The driver shall present the three copies of the validated manifest to the Canadian Customs officer at the Canadian port of exit for certification. That officer shall verify that the seals are intact if the vehicle has been sealed or, if sealing has been waived, that there are no irregularities. After verification and certification of the manifest, two certified copies will be returned to the driver (one to be presented to U.S. Customs at the United States port of reentry, the other for the carrier's records), and the truck will be allowed to proceed to the United States.

(d) Procedure at United States port of reentry. The driver of a truck reentering the United States after transiting Canada shall present a certified copy of the United States-Canada Transit Manifest, Customs Form 7512-B Canada 8 1/2, to the U.S. Customs officer. If this copy of the manifest does not bear the certification of a Canadian Customs officer at the Canadian port of exit, the driver will be allowed to return to that port to have it certified. The driver will be allowed to break any seals affixed by Canadian Customs upon presentation of a certified manifest. If sealing has been waived, the U.S. Customs officer shall satisfy himself that the truck contains only that merchandise covered by the manifest which moved on the truck from the United States through Canada.

(e) Proof of exportation from Canada. The certified copy of the manifest returned to the driver by Canadian Customs at the Canadian port of exit will serve as proof of exportation of the shipment from Canada.

(a) Manifest required. Trucks with merchandise transiting the United States from point to point in Canada will be manifested on United States-Canada Transit Manifest, Customs Form 7512-B Canada 8 1/2. The driver, in accordance with Canadian Customs regulations, shall present the manifest in four copies to Canadian Customs at the Canadian port of departure for review and validation.

(b) Procedure at Canadian port of departure. The Customs officer receiving the manifest shall validate it by stamping each copy in the lower right hand corner to show the port name and date and by initialing each copy. All copies of the validated manifest then will be returned to the driver for presentation to U.S. Customs at the United States port of entry.

(c) Procedure at U.S. port of arrival—(1) Filing of in-bond application. An in-bond application must be filed pursuant to § 18.1 of this chapter prior to or upon arrival at a U.S. port. At CBP's discretion the driver may be required to present four validated copies of the United States-Canada Transit Manifest, CBP Form 7512-B Canada 8 1/2, to the CBP officer, who will review the manifest for accuracy and verify its validation by Canadian Customs. If the manifest is found not to be validated properly, the truck will be required to be returned to the Canadian port of departure so that the manifest may be validated in accordance with Canadian Customs regulations. If the manifest is validated properly and no irregularity is found, the truck will be sealed unless sealing is waived by CBP. The CBP officer will note in the in-bond record and, if paper, on the manifest, the seal numbers or the waiver of sealing, retain the original, and return three copies of the manifest to the driver for presentation to CBP at the U.S. port of exportation.

(2) Sealing or waiver of sealing. Trucks transiting the United States will be sealed with red in-bond seals at the United States port of arrival unless sealing is waived in accordance with § 18.4 of this chapter. If a truck cannot be sealed effectively and sealing is deemed necessary to protect the revenue or to prevent violation of the Customs laws or regulations, the truck will not be permitted to transit the United States under bond.

(d) Procedure at U.S. port of exportation. The arrival of the in-bond shipment at the port of exportation must be reported to CBP in accordance with § 18.1 of this chapter.

(1) If the seals are intact, they will be left unbroken unless there is indication that the contents should be verified.

(2) If the seals have been broken, or there is other indication that the contents should be verified, all merchandise will be required to be unladen and a detailed inventory made against the waybills.

(e) Procedure at Canadian port of reentry. The driver of a truck reentering Canada after transiting the United States shall present a certified copy of the United States-Canada Transit Manifest, Customs Forms 7512-B Canada 8 1/2, to the Canadian Customs officer. If this copy of the manifest does not bear the certification of a U.S. Customs officer at the United States port of exit, the driver will be allowed to return to that port to have it certified.

(f) Proof of exportation from United States. The certified copy of the manifest returned to the driver by the U.S. Customs officer at the U.S. port of exit will serve as proof of exportation of the shipment from the U.S.

(g) Forwarding procedure. Except as otherwise provided in this section, merchandise transported in trucks shall be forwarded in accordance with the general provisions for transportation in bond (§§ 18.1-18.8 of this chapter).
