(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.
ARTICLE XX
Through consideration for the interests of commerce generally, it is agreed, that if less than sixty
days should elapse between the date of the signature of this treaty and the restoration of the custom
houses, conformably with the stipulation in the third article, in such case all merchandise, effects and
property whatsoever, arriving at the Mexican ports after the restoration of the said custom-houses,
and previously to the expiration of sixty days after the day of signature of this treaty, shall be
admitted to entry; and no other duties shall be levied thereon than the duties established by the tariff
found in force at such custom-houses at the time of the restoration of the same. And to all such
merchandise, effects, and property, the rules established by the preceding article shall apply.
ARTICLE XXI
If unhappily any disagreement should hereafter arise between the Governments of the two
republics, whether with respect to the interpretation of any stipulation in this treaty, or with respect to
any other particular concerning the political or commercial relations of the two nations, the said
Governments, in the name of those nations, do promise to each other that they will endeavour, in the
