The ATA Carnet is an international customs document that allows the holder to temporarily (up to one year) import goods without payment of normally applicable duties and taxes, including value-added taxes. The Carnet eliminates the need to purchase temporary import bonds. So long as the goods are re-exported within the allotted time frame, no duties or taxes are due.
Mexico accepts the ATA Carnet in all of its entry points.
For larger projects, we suggest to rent the equipment in Mexico or make a temporary import through a customs agent.
