(1) All such merchandise, effects, and property, if imported previously to the restoration of the custom-houses to the Mexican authorities, as stipulated for in the third article of this treaty, shall be exempt from confiscation, although the importation of the same be prohibited by the Mexican tariff.
(2) The same perfect exemption shall be enjoyed by all such merchandise, effects, and property, imported subsequently to the restoration of the custom-houses, and previously to the sixty days fixed in the following article for the coming into force of the Mexican tariff at such ports respectively; the said merchandise, effects, and property being, however, at the time of their importation, subject to the payment of duties, as provided for in the said following article.
(3) All merchandise, effects, and property described in the two rules foregoing shall, during their continuance at the place of importation, and upon their leaving such place for the interior, be exempt from all duty, tax, or imposts of every kind, under whatsoever title or denomination. Nor shall they be there subject to any charge whatsoever upon the sale thereof.
(4) All merchandise, effects, and property, described in the first and second rules, which shall have been removed to any place in the interior, whilst such place was in the occupation of the forces of the United States, shall, during their continuance therein, be exempt from all tax upon the sale or consumption thereof, and from every kind of impost or contribution, under whatsoever title or denomination.
(5) But if any merchandise, effects, or property, described in the first and second rules, shall be removed to any place not occupied at the time by the forces of the United States, they shall, upon their introduction into such place, or upon their sale or consumption there, be subject to the same duties which, under the Mexican laws, they would be required to pay in such cases if they had been imported in time of peace, through the maritime custom-houses, and had there paid the duties conformably with the Mexican tariff.
(6) The owners of all merchandise, effects, or property, described in the first and second rules, and existing in any port of Mexico, shall have the right to reship the same, exempt from all tax, impost, or contribution whatever.
With respect to the metals, or other property, exported from any Mexican port whilst in the occupation of the forces of the United States, and previously to the restoration of the custom-house at such port, no person shall be required by the Mexican authorities, whether general or state, to pay any tax, duty, or contribution upon any such exportation, or in any manner to account for the same to the said authorities.
