Product Compliance

On 22 September, Mexico wrote a fine, not a seizure, into its customs rules for incomplete product labels: it only survives if the product underneath the paperwork error still meets the standard

On 19 November 2025, Mexico's Customs Law reform removed the correction window for incomplete commercial-information labelling, folding it into broadened precautionary-embargo grounds from 1 January 2026. On 8 September 2026, customs agency ANAM clarified that a fine of 2% to 10% of commercial value still applies, instead of seizure, when the importer can accredit that the product itself meets the standard and only the data is wrong. On 22 September 2026, that distinction was written into the general foreign-trade rules themselves, in force since 23 September.

What actually changes, and on which date

Mexico requires almost every physical consumer product sold in the country, clothing, footwear, electronics, toys, cosmetics and packaged food among them, to carry commercial-information labelling under a Norma Oficial Mexicana (NOM): the manufacturer's and importer's name and address, the country of origin, a product description or model, and, in many sectors, care or safety instructions, all in Spanish. For years, a customs inspection that found this data missing or wrong, as opposed to the product itself failing the standard, triggered retention of the goods with a window of business days to correct the paperwork and pay a fine of 2% to 10% of the merchandise's commercial value under Articles 184, fraction XIV, and 185, fraction XIII, of the Ley Aduanera (Customs Law). The decree published in the Diario Oficial de la Federación on 19 November 2025 repealed that retention carve-out and folded commercial-information non-compliance into the law's broadened precautionary-embargo grounds, effective from 1 January 2026, meaning a data error detected at the border could now be treated the same as any other customs violation serious enough for the goods to be seized outright.

That is where most September 2026 compliance alerts left the story. ANAM's Press Release 74/2026, published 8 September 2026, added the part they did not: an orienting criterion instructing customs officials that when the importer can accredit that the product itself complies with the applicable NOM, and the irregularity is limited to omitted or inaccurate data, the fine under Articles 184-XIV and 185-XIII still applies instead of embargo. Two weeks later, on 22 September 2026, SAT published the Segunda Resolución de Modificaciones a las Reglas Generales de Comercio Exterior para 2026 (Second Resolution Amending the 2026 General Foreign Trade Rules) and its Annexes 1, 2 and 22 in the Diario Oficial de la Federación, writing that same fine-based treatment for accredited-but-mislabelled goods into the general rules rather than leaving it as an internal operating criterion. The resolution took effect 23 September 2026, with exceptions for provisions SAT had already published in advance on its own portal.

Three details behind the 22 September rule

Two penalties, one condition

Whether a mislabelled product faces a fine or an embargo turns on one fact: can the importer accredit that the product itself meets the NOM, data error aside.

The window that disappeared was the general one

Since 1 January 2026, the correction window that used to apply to any commercial-information error is gone. It survives only through the fine track ANAM and SAT then carved back out.

An internal criterion became a general rule in 14 days

ANAM's 8 September criterion and SAT's 22 September resolution state the same fine-over-embargo distinction, the second giving it the binding form of a published rule.

19 Nov 2025

The Diario Oficial de la Federación publishes the Customs Law reform repealing the retention carve-out for NOM commercial-information non-compliance and broadening the law's precautionary-embargo grounds.

1 Jan 2026

The reform takes effect: a commercial-information data error detected during customs clearance becomes, by default, grounds for precautionary embargo rather than a business-days correction window.

8 Sep 2026

ANAM publishes Press Release 74/2026, an orienting criterion instructing customs officials to apply the Article 184-XIV / 185-XIII fine (2% to 10% of commercial value), not embargo, when NOM compliance is accredited and only data is omitted or inaccurate.

22 Sep 2026

SAT publishes the Segunda Resolución de Modificaciones a las RGCE 2026 in the DOF, writing the same fine-based treatment into the general foreign-trade rules; in force from 23 September 2026.

The numbers behind the 22 September rule

One number is the cost of landing on the fine track instead of the embargo track. One is how quickly an internal customs criterion became a published general rule. The third is how many separate legal texts an importer now has to read together to know which track applies to them.

legal texts an importer now has to read together to know its exposure: the November 2025 Customs Law reform, the 8 September ANAM criterion, and the 22 September RGCE resolution

The real subject: enforcement that reads the product before it reads the label

Most coverage of Mexico's 2026 customs reform compresses it into a single line: the correction window is gone, so any commercial-information slip can now get goods seized at the border. That line is accurate about the law's letter and incomplete about how it is actually being applied. The November 2025 reform did remove the general cushion, folding commercial-information non-compliance into the same precautionary-embargo grounds that apply to more serious customs violations. But ANAM's 8 September criterion, now codified in SAT's 22 September resolution, draws a second line inside that harsher framework: embargo is for goods that cannot be shown to meet the NOM at all, while a fine of 2% to 10% of commercial value is for goods that do meet it, where the only failure is in the data printed on the label, the invoice, or the customs declaration itself. The distinction does not turn on how the error looks to an inspector at the border. It turns on whether the importer can accredit, with its own documentation, that the physical product underneath the mislabelled data actually complies. That is a product-data question, not a paperwork-correction question, and it is answered before an inspection happens or not at all.

Why it matters for brands

Any brand exporting apparel, footwear, electronics, toys, cosmetics or packaged food into Mexico sells under a NOM that requires Spanish-language commercial-information labelling, country of origin, manufacturer and importer identity, product description or model, in addition to whatever sector-specific NOM applies to the product category itself. Since 1 January 2026, a mismatch between that label, the commercial invoice and the pedimento (the customs declaration) is no longer a problem a broker can quietly fix after an inspector flags it at the border; it can be treated as grounds for seizure. The 8 September and 22 September clarifications give brands a narrower, more specific task than simply reprinting correct labels: keep documentary proof, lab reports, supplier declarations, bills of materials, that the product itself meets the applicable NOM, filed and ready before goods ship, separately from the label text. A brand that can produce that proof on demand lands on the 2% to 10% fine track even if a data field was wrong. A brand that cannot is exposed to the embargo track the November 2025 reform broadened, regardless of how minor the mislabelling looks. For any brand onboarding a new SKU, supplier or market entry into Mexico, verifying that underlying NOM compliance, and keeping the evidence of it, now matters more than proofreading the label alone.

Two ways to read the 22 September rule

The narrow read

Since 1 January 2026, Mexico can seize goods at the border over incomplete or inaccurate commercial-information labelling, with no correction window left.

The structural read

That seizure risk now applies only when the product itself cannot be shown to comply. Since 22 September, a product that does comply, with the data error isolated to the paperwork, faces a fine of 2% to 10% of commercial value instead, provided the importer can prove the underlying compliance on its own records.

Frequently asked questions

What exactly changed in Mexico's customs rules on 22 September 2026?

SAT published the Segunda Resolución de Modificaciones a las Reglas Generales de Comercio Exterior para 2026 (Second Resolution Amending the 2026 General Foreign Trade Rules) in the Diario Oficial de la Federación, in force from 23 September 2026. Among other customs changes, it codifies into the general rules an orienting criterion ANAM had issued on 8 September 2026: when an importer can accredit that a product complies with the applicable Norma Oficial Mexicana (NOM) and the only irregularity is omitted or inaccurate commercial-information data, the penalty is a fine of 2% to 10% of the merchandise's commercial value under Articles 184-XIV and 185-XIII of the Ley Aduanera, rather than precautionary embargo.

Does this mean a mislabelled product is no longer at risk of seizure in Mexico?

No. The seizure risk introduced by the Customs Law reform that took effect 1 January 2026 is still real, and it is the default outcome. It applies to goods that cannot be shown to comply with the applicable NOM at all. The fine track confirmed on 8 and 22 September 2026 is narrower: it is available only when the importer can accredit that the product itself meets the standard and the error is confined to the commercial-information data on the label, invoice or customs declaration.

What should a brand exporting to Mexico check to land on the fine track rather than the embargo track?

Keep documentary proof, lab test reports, supplier declarations, bills of materials, that each product actually meets the NOM applicable to its category, filed and accessible before the goods ship, and separate from the label's printed text. Then ensure the country of origin, importer and manufacturer identity, and product description match exactly across the physical label, the commercial invoice and the pedimento. The fine track under Articles 184-XIV and 185-XIII is available only when that underlying compliance can be accredited; without it, a data mismatch falls under the broadened precautionary-embargo grounds in force since 1 January 2026.
