The document discusses challenges that US companies face with Mexico's IMMEX import regulations and provides solutions. Key changes to the IMMEX program include eliminating VAT exemptions, increasing VAT from 11% to 16%, requiring VAT payment at import, and providing a 100% VAT tax credit for certified companies. Companies must demonstrate proper management of their IMMEX program to Mexican authorities, but many lack expertise, procedures, or technology to do so. Partnering with a customs broker with expertise in Mexico can help companies overcome these challenges and establish themselves in the IMMEX program.
