SAT explains guarantees for disputed customs values
El CEO reports that SAT outlined how importers may replace precautionary seizures with guarantees under the customs reform. The changes take effect January 1, 2027.
Context
For goods outside the estimated-price regime, a value gap below 20% permits cash or a customs guarantee account, while a gap of 20% or more requires cash. Importers have ten working days after notification to request substitution. The amount covers taxes and compensatory duties on the value difference.
Why it matters
The guarantee may free the goods while tying up funds during the review. If documents establish lawful valuation, the decree requires release of the guarantee or return of the cash deposit. The implementing rules will determine how importers use this option.

Mexico’s digital-payments law enters into force
T21 reports that the digital-payments law was published November 4 and took effect November 5. Hacienda must still identify the first sectors subject to the requirements.
Context
T21 describes a gradual transition set by sector authorities after Hacienda names the sectors. Gas stations and toll booths are possible initial participants. The law allows cash or checks when a contingency prevents digital payment.
Why it matters
If carriers use digital payments for fuel and tolls while fares remain in cash, small carriers will need to deposit receipts to fund daily expenses. T21’s interviewed specialist identifies this cash-flow mismatch. The sector selection and transition rules will determine how soon carriers face it.

DPL News reports tighter FCC requirements for cross-border telecoms
DPL News reports that the U.S. Federal Communications Commission raised cybersecurity and disclosure requirements for telecom operators, including networks linking the United States with Mexico and Canada.
Context
According to DPL News, operators must disclose their border-network layouts and foreign ownership stakes of 5% or more. The report also describes requirements to exclude equipment and services on the FCC’s list of security risks.
Why it matters
Mexico-U.S. network links could face closer scrutiny of suppliers and ownership under the reported requirements. Their operational impact depends on which connections and providers are covered. The report does not establish when the requirements take effect.
