Mexico Ley Aduanera Structural Reform — ANAM Statutory Recognition, Consejo Aduanero Governance Organ, and IMMEX/OEA Surveillance Overhaul

Mechanism

The decree amends, adds to, and repeals more than 150 provisions of the Ley Aduanera — the foundational customs statute that governs all Mexican import/export procedures, customs-agent licensing, and bonded manufacturing. Five structural changes define the reform:

1. ANAM statutory recognition and expanded fiscal powers. The Agencia Nacional de Aduanas de México (created administratively in 2021) is formally embedded in the statute with expanded inspection, fiscalisation, and technological-verification powers at recintos fiscales and IMMEX warehouses. ANAM now holds direct audit-right authority at bonded-manufacturing sites, previously held only through SAT delegation. This materially changes the compliance calculus for ~3,200 IMMEX operators.

2. Consejo Aduanero — new governance organ. A four-member inter-secretarial body is established comprising SHCP (Secretaría de Hacienda y Crédito Público), SAT (Servicio de Administración Tributaria), ANAM, and the Secretaría Anticorrupción y Buen Gobierno. The Consejo holds binding decisional power over the granting, suspension, cancellation and extinction of patentes aduanales (customs-agent operating licences) and corporate authorisations (agencias aduanales). This fundamentally re-prices the regulatory-risk economics of Mexican customs-broker operations and creates a new institutional vehicle that will generate forward IPTM amendment events.

3. Mandatory real-time traceability infrastructure. All recintos fiscales and recintos fiscalizados must deploy electronic inventory control, video surveillance, security, and real-time traceability systems with full interoperability to the Ventanilla Única Electrónica (customs e-system). A 180-day deadline was set for technology-cooperation agreements with the Agencia de Transformación Digital y Telecomunicaciones (deadline ~18 May 2026).

4. IMMEX and OEA/Authorized Economic Operator scope tightening. Certification conditions for IMMEX bonded manufacturing and OEA status are tightened, imposing stricter controls on goods handling and customs-regime transitions. This raises compliance costs for nearshoring operators but simultaneously strengthens USMCA-origin-certification integrity — a negotiated trade-off given ongoing US scrutiny of Chinese-entity IMMEX utilisation.

5. Enhanced penalties and new conduct categories. Penalties for customs-law violations are increased and new categories of sanctionable conduct are introduced for customs agents and importers, including digital-system manipulation and failure to maintain mandated traceability records.

Downstream implications

• Nearshoring platform integrity: Mexico's ~3,200 IMMEX operators collectively underpin the

USMCA-origin compliance chain for roughly US$800bn in annual MX-US merchandise trade. ANAM's expanded fiscalisation powers and the mandatory traceability mandate raise compliance infrastructure requirements but simultaneously defend against tariff-rule-shopping (Chinese entities routing exports via Mexican IMMEX without genuine value-add) — directly relevant to ongoing US Section 232/301 enforcement and USMCA Chapter 32 consultation risk.

• Customs-broker licensing re-rating: The Consejo Aduanero's binding authority over patentes aduanales

creates an administrative bottleneck risk and a concentration-of-oversight concern. Major agencias aduanales (AFAC, Fedex Trade Networks MX, DHL Global Forwarding MX, Kuehne+Nagel MX) will need to maintain ongoing regulatory relationships with a four-ministry body rather than primarily SAT.

• Technology-agreement milestones: The ~18 May 2026 technology-cooperation deadline has already

passed without public notification; tracking the implementation status of the mandatory e-inventory / video-surveillance rollout at recintos fiscales is a near-term IPTM amendment trigger.

• Reglamento de la Ley Aduanera reform: The decree required a reform to the Reglamento within

120 calendar days (deadline ~17 March 2026). Holland & Knight reported the follow-on Reglamento reform was published in February 2026, operationalising the new ANAM powers and Consejo Aduanero procedures. A separate IPTM filing for the Reglamento reform may be warranted if CAMEX/SAT issues implementing rules.

• LIGIE/TIGIE tariff architecture: The Ley Aduanera reform operates as the legal-enforcement

architecture that conditions the effectiveness of the concurrent 29-Dec-2025 LIGIE 1,463-line MFN tariff hike and the 23-Apr-2026 TIGIE/PROSEC decree — enforcement and tariff instruments are now co-dependent.

Open questions

• Has the mandatory Reglamento reform (120-day deadline ~17-Mar-2026) been published in full? Holland &

Knight confirms a Feb-2026 publication; full text and IPTM amendment tracking warranted.

• What is the current status of technology agreements between ANAM/SAT and the Agencia de Transformación

Digital? The ~18 May 2026 180-day deadline has just passed — no public announcement of signed agreements found as of this filing.

• How will the Consejo Aduanero's first licensing decisions (granting, suspension, cancellation of patentes

aduanales) be published and tracked? SAT/ANAM transparency portals are the expected venue.

• Will Chinese-entity IMMEX operators face targeted ANAM audits under the expanded fiscalisation powers,

and if so, what is the trigger threshold? This is the key US-facing dimension of the enforcement reform.
