The High Contracting Parties agree that all shipments of merchandise crossing the International Boundary line between the United States and Mexico, originating in and consigned from either of the [Page 511] two countries, shall be covered by a shipper’s export declaration, and a copy of same, verified by the appropriate officials of the country of origin, shall be furnished to the customs officials of the country of destination. It is agreed also that the appropriate officials of either country shall give such information as the appropriate officials of the other country may request concerning the transportation of cargos or the shipment of merchandise crossing the International Boundary line.
The High Contracting Parties agree that clearance of shipments of merchandise by water, air or land from any of the ports of either country to a port of entrance of the other country shall be denied if such shipment comprises articles the introduction of which is prohibited or restricted for whatever cause in the country to which such shipment is destined, provided, however, that such clearance shall not be denied on shipments of restricted merchandise when there has been complete compliance with the conditions of the laws of both countries.
It shall also be deemed to be the obligation of both of the High Contracting Parties to prevent by every possible means, in accordance with the laws of each particular country, the clearance of any vessel or other vehicle laden with merchandise destined to any port or place when there shall be reasonable cause to believe that such merchandise or any part thereof, whatever may be its ostensible destination, is intended to be illegally introduced into the territory of the other Party.
The High Contracting Parties reciprocally agree to exchange promptly all available information concerning the names and activities of all persons known or suspected to be engaged in violations of the laws of the United States or Mexico with respect to smuggling or the introduction of prohibited or restricted articles.
The High Contracting Parties agree that no merchandise or property of any character shall be authorized to be cleared or despatched out of either country, across the International Boundary line, except through ports or places duly authorized to clear such merchandise or property, and to or through duly authorized ports or places on the opposite side of said Boundary line; provided, that merchandise or property may be transported across said boundary [Page 512] line at any convenient place’ under special circumstances and after permits by both countries have been issued therefor.
The High Contracting Parties agree that they will exchange all available information concerning the existence and extent of contagious and infectious diseases of persons, animals, birds or plants, and the ravages of insect pests and the measures being taken to prevent their spread. The parties will also exchange information relative to the study and use of the most effective scientific and administrative means for the suppression and eradication of such diseases and insect pests.
Section II—Migration of Persons
Each of the High Contracting Parties agrees to employ all reasonable measures to prevent the departure of persons destined to territory of the other, except at or through regular ports or places of entry or departure established by the High Contracting Parties.
In all cases in which a national of. one of the High Contracting Parties is to be deported or expelled from the territory of the other, and in the cases in which a national of either country subject to deportation is allowed voluntarily to depart for the country of his nationality in lieu of deportation, due notice will be given the proper Consular representative of the country of such national.
In all cases in which either of the High Contracting Parties may suspend or waive its regulations relating to the contracting of laborers in the territory of the other, or in cases where either of the High Contracting Parties may grant special permits for contract labor, the country granting such permits or so suspending or waiving its regulations will give due notice thereof to the other.
The High Contracting Parties mutually agree that they will exchange information regarding persons proceeding to the country of the other and regarding activities of any persons on either side of the border, when there is reasonable ground to believe that such persons are engaged in unlawful migration activities or in conspiracies [Page 513] against the other Government or its institutions, when not incompatible with the public interest.
