Customs Tightening on the Road to 2027: A Brief Overview of How Much Customs Regulation Has Changed This Year and What Trends Point to for the Near Future

Introduction

It is no secret to anyone that there has been an enormous shift in public policy regarding regulatory compliance within the customs and foreign trade sector, where the regulatory squeeze is even more evident due to a series of controls introduced throughout the year.

Recent customs reforms in Mexico reveal a profound transformation: the Mexican State (not to mention the enormous pressures from the international financial system) has left behind reactive review models in order to establish an ecosystem of proactive, technology-driven, real-time oversight.

In my view, 2026 will go down in history as one of the key years in which regulation became truly strict, in line with various international frameworks, forcing countless companies to enter state-of-the-art formality and foreign trade registries. The issue is that legal defense against omissions has become significantly more expensive, since today a single customs defense before the courts is not an effective solution to these diverse challenges.

The question I would like to put to other business owners and taxpayers engaged in foreign trade, and not only to fellow lawyers, is: how did we get here? And what does the future hold for us, as users of the customs system, amid so many changes?

The Incoming “New Order”

As I mentioned earlier, severe penalties and litigation risk have increased dramatically for business taxpayers with weak compliance frameworks.

This reality hits especially hard for companies that use various foreign trade models, which now face suffocating scrutiny of their operations, partners and supply chains.

The most relevant of these include, among others, the following:

A) Various Amendments to the LFPIORPI (Anti-Money Laundering Law) Regarding Customs

In the transition toward 2027, one of the most aggressive fronts is the update of the Anti-Money Laundering Law (LFPIORPI) in customs matters. The provision of foreign trade services by customs brokers and customs agencies is a vulnerable activity (Article 17, Section XIV of the LFPIORPI) when it involves certain types of goods (vehicles, jewelry, metals, works of art, armoring, etc.), and the recent amendment to its Regulations and the new General Rules radically change the situation for those who carry out vulnerable activities. Simple report filing is being abandoned in favor of a Risk-Based Approach (RBA), forcing companies to mandatorily implement assessment methodologies, classify their clients and update their internal manuals.

With a transition period beginning on November 30, 2026, the real challenge will arrive on March 1, 2027, the date on which automated monitoring systems, audits and enhanced due diligence will become mandatory.

In this same area, operational rigidity becomes extreme with the new obligation to report, within a maximum of 24 hours, any attempted suspicious or unconsummated transaction.

In addition, monitoring of the six-month accumulation of transactions is now stricter, requiring immediate notice as soon as the threshold is approached, without waiting for the end of the semester.

Added to this is the exclusion of tax payments from the calculation of these thresholds and relentless scrutiny, backed by law, to identify the Ultimate Beneficial Owner and permanently monitor Politically Exposed Persons (PEPs).

It is definitely no cliché that so many law firms are so emphatic about this first mechanism.

B) Amendment to the Customs Law and Real-Time Oversight

For its part, the foreign trade ecosystem is undergoing a complete restructuring under the amendments to the Customs Law in force this year.

The integration of the comprehensive “Electronic File” now requires importers to include minimum documentation such as contracts, CFDI (electronic invoices), value analyses, proof of transfers and payments of incrementables.

The environment becomes even more emphatic in penalizing irregularities by establishing full joint and several liability for customs brokers regarding the accuracy of the data, transforming their lifetime licenses into 20-year concessions with recertification every three years, and applying fines of up to 300% for omitted contributions or false data.

C) Complement with Tax Matters Through the 2027 Economic Package

The customs outlook for next year is even more challenging due to the 2027 Economic Package initiative currently under review by the Chamber of Deputies, which seeks to tackle undervaluation head-on.

If approved, this proposal could remove the 50% threshold that previously applied to precautionary seizures, granting customs authorities the power to carry out seizures immediately upon any difference detected between the value declared by the importer and the price assigned by the authority.

As financial journalist Dainzú Patiño rightly points out in an article in the popular financial newspaper “Expansión”, a change of that magnitude, applied nationwide and across the board, threatens to cause severe logistical delays and cost overruns, particularly affecting industries that operate their supply chains under the Just in Timemodel, with the imminent risk of overloading bonded facilities at customs.

D) Home Audits “on Steroids” and Their Complement with the Amendment to the General Foreign Trade Rules

Moreover, these customs and anti-money laundering measures are complemented by tax developments with indirect impact that accelerate corporate penalties. The Federal Tax Code (CFF) now empowers the SAT (Tax Administration Service) to conduct express home audits, lightning audits that, if not refuted by the taxpayer within just five days, result in the immediate restriction of digital invoicing seals. In parallel, the Second Resolution of Amendments to the 2026 RGCE (General Foreign Trade Rules), published in September of this year, adds operational pressure by setting new specifications on fines for lack of labeling and establishing strict grounds for resolving suspensions in the Electronic Customs System (SEA) arising from errors in the NICO (Commercial Identification Number) within the SNICE (National Foreign Trade Information Service) platform... What a number of acronyms! The trend toward ultra-specialization of the field is evident, and it serves as a prelude to the final question.

What Lies Ahead?

The tightening of tax and customs policies in 2026 has laid the foundations for a relentless oversight State, and projections for 2027 point to an unprecedented level of sanction-driven demands.

In the humble opinion of the author, this scenario makes large-scale foreign trade an even more complex niche for merchants seeking to formalize and institutionalize their operations, even discouraging the transition to full legality and indirectly encouraging an increase in informality.

To survive in this ecosystem, foreign trade companies must internalize that regulatory compliance is no longer a mere administrative formality, but the fundamental strategic shield that will prevent operational shutdowns, immediate seizures and costly litigation that could jeopardize their profitability and continuity.

RELEVANT POINTS

  • From reactive review to real-time oversight. The 2026 reforms consolidate a model of proactive, technology-driven oversight in customs and foreign trade. Penalties and litigation risk fall more heavily on companies with weak compliance frameworks, and a single defense before the courts is no longer enough.
  • Risk-Based Approach under the LFPIORPI. The provision of foreign trade services by customs brokers and customs agencies is a vulnerable activity (Article 17, Section XIV) when it involves goods such as vehicles, jewelry, metals, works of art or armoring. The amendment to the Regulations and the new General Rules require risk assessment methodologies, client classification and updating of internal manuals.
  • Key dates: November 30, 2026 and March 1, 2027. The transition period begins at the end of November; starting in March 2027, automated monitoring systems, audits and enhanced due diligence will be mandatory.
  • 24-hour reporting and stricter thresholds. Any attempted suspicious or unconsummated transaction must be reported within a maximum of 24 hours. The six-month accumulation of transactions requires immediate notice when the threshold is approached, and tax payments are excluded from its calculation.
  • Ultimate Beneficial Owner and PEPs. The law supports permanent scrutiny to identify the Ultimate Beneficial Owner and monitor Politically Exposed Persons, which requires in-depth knowledge of the structure of clients and partners.
  • Comprehensive Electronic File. With the amendment to the Customs Law, importers must compile minimum documentation such as contracts, CFDI, value analyses, proof of transfers and payments of incrementables.
  • New regime for customs brokers. Their full joint and several liability for the accuracy of the data is established, lifetime licenses become 20-year concessions with recertification every three years, and fines for omitted contributions or false data reach 300%.
  • Precautionary seizures without the 50% threshold. The 2027 Economic Package initiative, under review in the Chamber of Deputies, proposes allowing immediate seizures upon any difference between the declared value and the price assigned by the authority. If approved, it could cause logistical delays, cost overruns and saturation of bonded facilities, with the greatest impact on supply chains Just in Time.
  • Express home audits. The Federal Tax Code empowers the SAT to conduct lightning audits; if the taxpayer does not refute the findings within five days, their digital invoicing seals are immediately restricted.
  • Second Resolution of Amendments to the 2026 RGCE. Published in September, it specifies fines for lack of labeling and sets strict grounds for resolving suspensions in the Electronic Customs System (SEA) arising from errors in the NICO within the SNICE platform.
  • Compliance as a strategic shield. Faced with an increasingly demanding oversight State, regulatory compliance is no longer an administrative formality and becomes the main protection against operational shutdowns, immediate seizures and costly litigation.
