A padrón suspension is not a fine. Nothing is assessed, nothing is billed, and there is no line item to book against it. What happens instead is that the company loses the ability to file import entries, and every container already moving toward Mexico keeps moving toward a port where it cannot be cleared.
That is the reframe a finance team needs. A fine is a number you pay once. A suspension is a stop on the company's ability to trade, and the exposure scales with how much cargo is in motion on the day it lands.
Two clocks start at the same moment, and the company controls neither of them. One runs at the port, where free storage ends in days. The other runs at SAT, where reinstatement is measured in a different unit entirely. Most operations discover the gap between the two only once.
The register is an operating status, not a certificate
Artículo 59, fracción IV of the Ley Aduanera requires importers to be registered and active in the Padrón de Importadores, Mexico's importer register, and, for the goods listed in Anexo 10 of the Reglas Generales de Comercio Exterior (RGCE), in the Padrón de Importadores de Sectores Específicos as well. Steel, iron and steel products, footwear, textiles and apparel, automotive, hydrocarbons and fuels, chemicals, precursors, ethyl alcohol and cigarettes each sit in their own sector, each with its own documentary conditions.
That status has to hold on the day of every filing, not on the day it was granted. Nothing about a padrón is permanent. Rule 1.3.3 of the RGCE lists the conditions under which SAT suspends the register, and the list runs to more than thirty separate grounds. Some of them describe conduct. Many of them describe housekeeping.
A suspension can also be partial. Where the failure belongs to a single sector, the register can be suspended in that sector alone, and reinstatement is then filed for that sector alone. That distinction matters commercially: a company can lose steel and keep everything else, which is worse than it sounds if steel is the line that funds the plant.
Where the money goes while the register is down
Cargo does not wait for a compliance file to be repaired. It sits, and it sits on a meter.
Under artículo 15, fracción V of the Ley Aduanera, facilities holding goods in customs deposit must allow free storage for two days on import cargo, and seven days at recintos fiscalizados located in maritime customs offices. Exports get fifteen days, and minerals thirty. Those windows are counted in calendar days and run from the day after the warehouse receives the goods. For imports arriving by sea or air, they run instead from the day the consignee is notified that the goods have entered the warehouse. After the window closes, storage is billable, and demurrage and detention run on separate commercial contracts with their own triggers.
Then the second threshold arrives, and it is computed on its own terms. Under artículo 29, goods in customs deposit are abandoned in favor of the federal treasury if they are not withdrawn within two months in the general case, and within three days for explosive, flammable, contaminating, radioactive or corrosive goods, as well as perishables and live animals. That three day window extends to as much as forty five days where the facility has the equipment to maintain the goods, and to fifteen calendar days for petroleum products. Artículo 30 starts that clock the day after the goods enter the warehouse, except in maritime traffic, where it starts the day after discharge of the vessel is completed. Artículo 32 then gives the company one more turn: once the abandonment period has run, the authority notifies the owner, consignee or destinatario personally at the address on the transport document and allows fifteen days to withdraw the goods after proving compliance and paying what is owed. The November 2025 reform to the Ley Aduanera added that when the transport document does not identify or locate that party, the notice is posted at the customs office instead of delivered.
Quick check: ask your team for one number today, before you need it. For the three ports that carry the most volume for your operation, what does one held day cost per container, counting storage after the free period, demurrage and detention under your current carrier contracts, and the working capital tied to the shipment? A company that can produce that number in an hour can size a suspension. A company that cannot will spend the first week of one estimating instead of fixing.
What actually triggers it
Rule 1.3.3 rewards reading, because its grounds fall into four groups that behave very differently.
The first group is administrative standing. An expired e.firma. Contact methods for the buzón tributario that were never registered or never updated. Federal tax returns not filed, or any other tax obligation left open. A suspension or cancellation notice filed at the RFC. A tax domicile where the company cannot be located, or an address change made without the corresponding notice. None of this involves a shipment. All of it stops one.
The second group is dormancy. Not carrying out foreign trade operations for a period exceeding twelve months is a ground for suspension in its own right. This is the one that catches good operations: a program pauses for a cycle, a product line moves, a sector goes quiet, and the register goes with it.
The third group is documentary and operational. False documentation. Not holding the documents that support the foreign trade operations. Altered records. Accounting, inventories or control systems that are not kept, or are concealed, altered or destroyed. Supplier or importer details declared on the pedimento, the CFDI or the equivalent document that turn out to be false, nonexistent or unlocatable. A transit that is opened and never closed at the destination customs office within the applicable window.
The fourth group is linkage, and it is the one that travels. Being listed by SAT under artículos 69 and 69-B, fourth paragraph, of the Código Fiscal de la Federación, or having transacted with a listed party without demonstrating the goods or services were real. Having a resolution issued and notified that determines the company issues false tax receipts under artículo 49 Bis of the CFF. Holding a legal representative, partner or shareholder who belongs to a suspended company or was suspended personally without clearing it. And, as amended for 2026, being criminally investigated or bound over to process for participating in a tax, industrial property or copyright offense. The 2025 text spoke of being subject to criminal proceedings for the presumed commission of an offense. The current wording reaches earlier in the timeline.
On paper, group four is about misconduct. In practice, it is a governance exposure: the company can lose its ability to file because of a person on its cap table or a counterparty in its ledger, not because of anything the trade compliance team did or failed to do.
The notice arrives after the door closes
The suspension is immediate. The notice is not the trigger, it is the record.
Rule 1.3.3 requires the authority, once it becomes aware that a ground has been met, to notify the cause of the immediate suspension within five days, through the channels of artículo 134 of the Código Fiscal de la Federación. The register is already down while that notice is prepared and delivered.
Read that alongside the ground for suspension covering contact methods for the buzón tributario, and the design becomes clear. The channel through which the company learns it has been suspended is itself something the company is required to keep current, and failing to keep it current is one of the grounds. In our work across the corridor, the first practical signal of a suspension is rarely the notification. It is a filing that will not go through.
Reinstatement, measured honestly
The path back is ficha de trámite 7/LA of Anexo 2 of the RGCE, filed through the SAT portal for the register as a whole, or through a clarification case in Mi Portal when the suspension covers one or more specific sectors.
The published maximum for SAT to resolve the filing is fifteen days. That is the headline number, and it is the wrong number to plan around on its own, for three reasons.
First, the filing has to be complete before the clock means anything. The company must prove the ground that caused the suspension has been cured, and separately satisfy every standing condition: active RFC, valid e.firma, tax obligations current, tax domicile shown as located, buzón tributario validated, at least one customs broker or brokerage with a live patente and an updated encargo conferido, and no listing under artículos 69 or 69-B, fourth paragraph, of the CFF, and no artículo 49 Bis resolution outstanding.
Second, rule 1.3.4 adds a step that is invisible from outside. Where SAT does not hold enough evidence to judge whether the irregularity was actually cured, it forwards the proof to the administrative unit that generated the information in the first place, and that unit has up to fifteen calendar days to analyze it and report back. The fifteen day resolution window and the fifteen day internal review window are not the same clock.
Third, some grounds carry a price of admission. Where the importer was suspended and a PAMA was opened, or a record of facts or omissions was raised implying unpaid contributions, countervailing duties, transition measures or penalties, reinstatement requires filing a written statement expressly accepting the finding and paying the assessed liability. Where the suspension came from presenting false documentation to prove compliance with non-tariff regulations and restrictions, reinstatement additionally requires that the case not be a repeat offense and that the competent authority issue written agreement to the reinstatement.
There is one fast path, and it is narrow. Where the suspension was based on grounds the authority did not appreciate correctly, the rule provides that it is lifted immediately. That is a remedy for an error of assessment, not a remedy for a cure delivered late.
The valve for cargo already at the border
Rule 1.3.5 allows a suspended importer to request authorization to import on a single occasion while the reinstatement is pending. The request is filed with the Dirección General de Operación Aduanera of ANAM using form A5 of Anexo 1, and it cannot be filed until five days have passed since the 7/LA reinstatement request went in. Among the supporting documents is proof that the goods are already in customs deposit.
Then read the response time. The authorization is resolved within a period of up to three months from a complete filing.
Set the three clocks next to each other and the exposure becomes a planning problem rather than a legal one. Free storage ends in two days, or seven at a maritime port. Abandonment runs at two months in the general case, and at three days for perishables and hazardous cargo. The relief valve for cargo already sitting in deposit can take up to three months to open. The valve is real and it is worth filing, but no CFO should model it as the thing that saves the quarter.
What to hold before you need it
Nothing in this mechanism is difficult to survive if the file is clean before the notice arrives. Four items are verifiable this week and cost nothing to check: the expiry date on the company e.firma, the contact methods currently registered for the buzón tributario, the date of the last foreign trade operation against the twelve month dormancy threshold, and whether any current partner, shareholder or legal representative sits in a suspended company or on the 69-B list. Add a fifth if the operation is sectoral: whether the sector specific documents on file, permits, licenses, socio and accionista records, are the versions SAT holds today.
The right moment to bring in a broker on padrón standing is not the week the notice lands. It is the quarter before a sector is added, a shareholder changes, a domicile moves, or a product line goes quiet for twelve months.
A suspension is not a penalty a company absorbs. It is a stop on trading whose cost is set by two clocks the company does not control, and whose duration is set by how ready the file was on the day it started.
