U.S. companies operating Mexican maquilas or sourcing from Mexico face Mexican-side compliance: SAT/Aduanas customs, IMMEX program (if applicable), IVA (Mexican VAT), Mexican corporate tax, Mexican labor compliance. Coordination between Mexican-side counsel and U.S.-side advisor is the standard structure.
This guide covers Mexican-Side Compliance for U.S. Importers. For SMB importers and exporters, the practical implementation depends on volume, sector, and operational structure.
For background, see /usmca-cusma/ and our complete cross-border practice.
Mexican corporate structure
Most U.S. companies operating Mexican maquilas use Mexican S.A. de C.V. or shelter companies. Corporate structure affects tax and compliance.
SAT/Aduanas customs
Mexican-side customs entries through Aduanas. Pedimento documentation. Customs broker engagement.
IVA (Mexican VAT)
IMMEX operations have specific IVA treatment. IVA refunds and certifications require careful documentation.
Mexican labor compliance
Mexican labor law compliance is separate from U.S. labor law. IMMEX operations have specific worker classification requirements.
