Mexico’s Lower House Backs Customs Overhaul, Sets January 2026 Start

The bill now heads to the president for publication, with implementation set for January 1, 2026.

Overview

  • The Chamber of Deputies approved the Senate-backed changes to the Customs Law by 343–123 and sent the measure to the Executive, as opposition lawmakers warned it shifts burdens to brokers and small businesses.
  • Lawmakers revised the first transitory article to delay entry into force until January 1, 2026 rather than the day after publication.
  • The reform creates a new Customs Council and grants concurrent powers to SAT and ANAM, including authority to coordinate with the Digital Transformation Agency.
  • It mandates electronic pedimento records such as CFDI, commercial invoices and carta porte, and adds video surveillance and real-time traceability requirements.
  • It expands the catalog of infractions with higher fines, tightens joint liability for customs brokers, and ends lifetime patents in favor of renewable 20‑year terms.
