Overview and Background

On Tuesday, the Chamber of Deputies in Mexico approved in general terms the reform to the Customs Law proposed by Claudia Sheinbaum, the President of Mexico City. This reform aims to strengthen controls and penalties against customs agents, making them responsible for all foreign trade operations they participate in.

Voting Details

The vote saw 338 in favor of the Morena, Partido del Trabajo (PT), and Partido Verde’s draft, while 129 voted against from PAN, PRI, and Movimiento Ciudadano (MC). Following the approval, legislators began discussing the particulars of the 71 reserved articles.

Dictamen Fundamentation

Carol Antonio Altamirano, the President of the Chamber’s Hacienda Commission and a Morena member, explained during the dictamen fundamentation that this reform updates an outdated customs law to better combat corruption.

Criticism of the Reform

Patricia Flores, a diputada from Movimiento Ciudadano (MC), stated that her party could not support the dictamen as it “does not address the core issue, nor does it correct corruption within the government.”

Jericó Abramo Masso, a PRI diputado, criticized the lack of professionalization for customs officers and the excessive responsibility placed on customs agents. He argued, “The government is shirking its responsibilities and leaving all the burden to private entities.”

Federico Döring, a PAN diputado, dismissed claims that the reform would combat tax evasion and boost tax collection in Mexico’s 50 customs offices. He pointed out that the government failed to provide an estimate of additional tax revenue from this reform.

Key Provisions of the Customs Law Reform

The proposed customs law reform includes significant changes to key aspects of Mexico’s customs operations, such as holding customs agents fully and solidarily responsible for foreign trade operations they engage in.

The reform eliminates the exonerations of customs agents’ liability from the existing Customs Law, which previously absolved agents from responsibility if discrepancies in taxes or regulatory compliance issues resulted from false or misleading information provided by importers or exporters. These agents could not detect such issues as the information was not visible.

Now, under the new law, customs agents are jointly and severally liable alongside importers and exporters. Consequently, agents must verify that the information provided about a commodity is accurate and matches its intended import or export.

This change aims to counter daily practices in customs aimed at evading tax payments, such as smuggling or undervaluing goods. Additionally, the reform extends patent and authorization validity for customs agents and agencies to 20 years, with the possibility of extending it further. It mandates annual certification for agents, establishes a Customs Council to grant, renew, suspend, or revoke patents and authorizations, among other things.
